Jetty Component

The jetty component provides HTTP-based endpoints for consuming and producing HTTP requests. That is, the Jetty component behaves as a simple Web server.
Jetty can also be used as a http client which mean you can also use it with Camel as a producer.

Info

title	Stream

The assert call appears in this example, because the code is part of an unit test.Jetty is stream based, which means the input it receives is submitted to Camel as a stream. That means you will only be able to read the content of the stream once.
If you find a situation where the message body appears to be empty or you need to access the Exchange.HTTP_RESPONSE_CODE data multiple times (e.g.: doing multicasting, or redelivery error handling), you should use Stream caching or convert the message body to a String which is safe to be re-read multiple times.

Maven users will need to add the following dependency to their pom.xml for this component:

Code Block

	xml
	xml

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jetty</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

Code Block
jetty:http://hostname[:port][/resourceUri][?options]

You can append query options to the URI in the following format, ?option=value&option=value&...

Options

Div

class	confluenceTableSmall

Name	Default Value	Description
`sessionSupport`	`false`	Specifies whether to enable the session manager on the server side of Jetty.
`httpClient.XXX`	`null`	Configuration of Jetty's HttpClient. For example, setting `httpClient.idleTimeout=30000` sets the idle timeout to 30 seconds. And `httpClient.timeout=30000` sets the request timeout to 30 seconds, in case you want to timeout sooner if you have long running request/response calls.
`httpClient`	`null`	To use a shared `org.eclipse.jetty.client.HttpClient` for all producers created by this endpoint. This option should only be used in special circumstances.
`httpClientMinThreads`	`null`	Camel 2.11: Producer only: To set a value for minimum number of threads in `HttpClient` thread pool. This setting override any setting configured on component level. Notice that both a min and max size must be configured. If not set it default to min 8 threads used in Jettys thread pool.
`httpClientMaxThreads`	`null`	Camel 2.11: Producer only: To set a value for maximum number of threads in `HttpClient` thread pool. This setting override any setting configured on component level. Notice that both a min and max size must be configured. If not set it default to max 16 threads used in Jettys thread pool.
`httpBindingRef`	`null`	Reference to an `org.apache.camel.component.http.HttpBinding` in the Registry. `HttpBinding` can be used to customize how a response should be written for the consumer.
`jettyHttpBindingRef`	`null`	Camel 2.6.0+: Reference to an `org.apache.camel.component.jetty.JettyHttpBinding` in the Registry. `JettyHttpBinding` can be used to customize how a response should be written for the producer.
`matchOnUriPrefix`	`false`	Whether or not the `CamelServlet` should try to find a target consumer by matching the URI prefix if no exact match is found. See here How do I let Jetty match wildcards.
`handlers`	`null`	Specifies a comma-delimited set of `org.mortbay.jetty.Handler` instances in your Registry (such as your Spring `ApplicationContext`). These handlers are added to the Jetty servlet context (for example, to add security). Important: You can not use different handlers with different Jetty endpoints using the same port number. The handlers is associated to the port number. If you need different handlers, then use different port numbers.
`chunked`	`true`	Camel 2.2: If this option is false Jetty servlet will disable the HTTP streaming and set the content-length header on the response
`enableJmx`	`false`	Camel 2.3: If this option is true, Jetty JMX support will be enabled for this endpoint. See Jetty JMX support for more details.
`disableStreamCache`	`false`	Camel 2.3: Determines whether or not the raw input stream from Jetty is cached or not (Camel will read the stream into a in memory/overflow to file, Stream caching) cache. By default Camel will cache the Jetty input stream to support reading it multiple times to ensure it Camel can retrieve all data from the stream. However you can set this option to `true` when you for example need to access the raw stream, such as streaming it directly to a file or other persistent store. DefaultHttpBinding will copy the request input stream into a stream cache and put it into message body if this option is `false` to support reading the stream multiple times. If you use Jetty to bridge/proxy an endpoint then consider enabling this option to improve performance, in case you do not need to read the message payload multiple times.
`throwExceptionOnFailure`	`true`	Option to disable throwing the `HttpOperationFailedException` in case of failed responses from the remote server. This allows you to get all responses regardles of the HTTP status code.
`transferException`	`false`	Camel 2.6: If enabled and an Exchange failed processing on the consumer side, and if the caused Exception was send back serialized in the response as a `application/x-java-serialized-object` content type. On the producer side the exception will be deserialized and thrown as is, instead of the `HttpOperationFailedException`. The caused exception is required to be serialized.
`bridgeEndpoint`	`false`	Camel 2.1: If the option is true , HttpProducer will ignore the Exchange.HTTP_URI header, and use the endpoint's URI for request. You may also set the throwExceptionOnFailure to be false to let the HttpProducer send all the fault response back. Camel 2.3: If the option is true, HttpProducer and CamelServlet will skip the gzip processing if the content-encoding is "gzip". Also consider setting disableStreamCache to true to optimize when bridging.
`enableMultipartFilter`	`true`	Camel 2.5: Whether Jetty `org.eclipse.jetty.servlets.MultiPartFilter` is enabled or not. You should set this value to `false` when bridging endpoints, to ensure multipart requests is proxied/bridged as well.
`multipartFilterRef`	`null`	Camel 2.6: Allows using a custom multipart filter. Note: setting `multipartFilterRef` forces the value of `enableMultipartFilter` to `true`.
filterInit.xxx	null	Camel 2.17: Configuration for the InitParameters of filter. For example, setting filterInit`.parameter=value` , the parameter could be used when calling the filter init method.
`filtersRef`	`null`	Camel 2.9: Allows using a custom filters which is putted into a list and can be find in the Registry
`continuationTimeout`	`null`	Camel 2.6: Allows to set a timeout in millis when using Jetty as consumer (server). By default Jetty uses 30000. You can use a value of `<= 0` to never expire. If a timeout occurs then the request will be expired and Jetty will return back a http error 503 to the client. This option is only in use when using Jetty with the Asynchronous Routing Engine.
`useContinuation`	`true`	Camel 2.6: Whether or not to use Jetty continuations for the Jetty Server.
`sslContextParametersRef`	`null`	Camel 2.8: Deprecated Reference to a `org.apache.camel.util.jsse.SSLContextParameters` in the Registry. This reference overrides any configured SSLContextParameters at the component level. See Using the JSSE Configuration Utility.
`sslContextParameters`	`null`	Camel 2.17: Reference to a `org.apache.camel.util.jsse.SSLContextParameters` in the Registry. This reference overrides any configured SSLContextParameters at the component level. See Using the JSSE Configuration Utility.
`traceEnabled`	`false`	Specifies whether to enable HTTP TRACE for this Jetty consumer. By default TRACE is turned off.
`optionsEnabled`	`false`	Camel 2.17: Specifies whether to enable HTTP OPTIONS for this Jetty consumer. By default OPTIONS is turned off.
`headerFilterStrategy`	`null`	Camel 2.11: Reference to a instance of `org.apache.camel.spi.HeaderFilterStrategy` in the Registry. It will be used to apply the custom headerFilterStrategy on the new create HttpJettyEndpoint.
`httpMethodRestrict`	`null`	Camel 2.11: Consumer only: Used to only allow consuming if the HttpMethod matches, such as GET/POST/PUT etc. From Camel 2.15 onwards multiple methods can be specified separated by comma.
`urlRewrite`	`null`	Camel 2.11: Producer only Refers to a custom `org.apache.camel.component.http.UrlRewrite` which allows you to rewrite urls when you bridge/proxy endpoints. See more details at UrlRewrite and How to use Camel as a HTTP proxy between a client and server.
`responseBufferSize`	`null`	Camel 2.12: To use a custom buffer size on the `javax.servlet.ServletResponse`.
`proxyHost`	`null`	Camel 2.11: Producer only The http proxy Host url which will be used by Jetty client.
`proxyPort`	`null`	Camel 2.11: Producer only The http proxy port which will be used by Jetty client.
`sendServerVersion`	`true`	Camel 2.13: if the option is true, jetty will send the server header with the jetty version information to the client which sends the request. NOTE please make sure there is no any other camel-jetty endpoint is share the same port, otherwise this option may not work as expected.
`sendDateHeader`	`false`	Camel 2.14: if the option is true, jetty server will send the date header to the client which sends the request. NOTE please make sure there is no any other camel-jetty endpoint is share the same port, otherwise this option may not work as expected.
`enableCORS`	`false`	Camel 2.15: if the option is true, Jetty server will setup the CrossOriginFilter which supports the CORS out of box.
okStatusCodeRange	`200-299`	Camel 2.16: Producer only The status codes which is considered a success response. The values are inclusive. The range must be defined as from-to with the dash included.

Message Headers

Camel uses the same message headers as the HTTP component.
From Camel 2.2, it also uses (Exchange.HTTP_CHUNKED,CamelHttpChunked) header to turn on or turn off the chuched encoding on the camel-jetty consumer.

Camel also populates all request.parameter and request.headers. For example, given a client request with the URL, http://myserver/myserver?orderid=123, the exchange will contain a header named orderid with the value 123.

Starting with Camel 2.2.0, you can get the request.parameter from the message header not only from Get Method, but also other HTTP method.

Usage

The Jetty component supports both consumer and producer endpoints. Another option for producing to other HTTP endpoints, is to use the HTTP Component

Component Options

The JettyHttpComponent provides the following options:

Div

class	confluenceTableSmall

`errorHandler`	`null`	Camel 2.15: This option is used to set the ErrorHandler that Jetty server uses.
allowJavaSerializedObject	`false`	Camel 2.16.1/2.15.5: Whether to allow java serialization when a request uses context-type=application/x-java-serialized-object. This is by default turned off. If you enable this then be aware that Java will deserialize the incoming data from the request to Java and that can be a potential security risk.

Producer Example

The following is a basic example of how to send an HTTP request to an existing HTTP endpoint.

in Java DSL

Code Block

	java
	java

from("direct:start").to("jetty://http://www.google.com");

or in Spring XML

Code Block

	xml
	xml

<route>
    <from uri="direct:start"/>
    <to uri="jetty://http://www.google.com"/>
<route>

Consumer Example

In this sample we define a route that exposes a HTTP service at http://localhost:8080/myapp/myservice:

Wiki Markup
{snippet:id=e1\|lang=java\|url=camel/trunk/components/camel-jetty9/src/test/java/org/apache/camel/component/jetty/JettyRouteTest.java}

Note

title	Usage of localhost

When you specify localhost in a URL, Camel exposes the endpoint only on the local TCP/IP network interface, so it cannot be accessed from outside the machine it operates on.

If you need to expose a Jetty endpoint on a specific network interface, the numerical IP address of this interface should be used as the host. If you need to expose a Jetty endpoint on all network interfaces, the 0.0.0.0 address should be used.

Tip
To listen across an entire URI prefix, see How do I let Jetty match wildcards.

Tip
If you actually want to expose routes by HTTP and already have a Servlet, you should instead refer to the Servlet Transport.

Our business logic is implemented in the MyBookService class, which accesses the HTTP request contents and then returns a response.
Note: The assert call appears in this example, because the code is part of an unit test.

Wiki Markup
{snippet:id=e2\|lang=java\|url=camel/trunk/components/camel-jetty9/src/test/java/org/apache/camel/component/jetty/JettyRouteTest.java}

The following sample shows a content-based route that routes all requests containing the URI parameter, one, to the endpoint, mock:one, and all others to mock:other.

Wiki Markup
{snippet:id=e1\|lang=java\|url=camel/trunk/components/camel-jetty9/src/test/java/org/apache/camel/component/jetty/JettyContentBasedRouteTest.java}

So if a client sends the HTTP request, http://serverUri?one=hello, the Jetty component will copy the HTTP request parameter, one to the exchange's in.header. We can then use the simple language to route exchanges that contain this header to a specific endpoint and all others to another. If we used a language more powerful than Simple (such as EL or OGNL) we could also test for the parameter value and do routing based on the header value as well.

Session Support

The session support option, sessionSupport, can be used to enable a HttpSession object and access the session object while processing the exchange. For example, the following route enables sessions:

Code Block

	xml
	xml

<route>
    <from uri="jetty:http://0.0.0.0/myapp/myservice/?sessionSupport=true"/>
    <processRef ref="myCode"/>
<route>

The myCode Processor can be instantiated by a Spring bean element:

Code Block

	xml
	xml

<bean id="myCode"class="com.mycompany.MyCodeProcessor"/>

Where the processor implementation can access the HttpSession as follows:

Code Block

	java
	java

public void process(Exchange exchange) throws Exception {
    HttpSession session = exchange.getIn(HttpMessage.class).getRequest().getSession();
    ...
}

SSL Support (HTTPS)

Using the JSSE Configuration Utility

As of Camel 2.8, the Jetty component supports SSL/TLS configuration through the Camel JSSE Configuration Utility. This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels. The following examples demonstrate how to use the utility with the Jetty component.

Programmatic configuration of the component

Code Block

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

SSLContextParameters scp = new SSLContextParameters();
scp.setKeyManagers(kmp);

JettyComponent jettyComponent = getContext().getComponent("jetty", JettyComponent.class);
jettyComponent.setSslContextParameters(scp);

Spring DSL based configuration of endpoint

Code Block

	xml
	xml

...
  <camel:sslContextParameters
      id="sslContextParameters">
    <camel:keyManagers
        keyPassword="keyPassword">
      <camel:keyStore
          resource="/users/home/server/keystore.jks"
          password="keystorePassword"/>
    </camel:keyManagers>
  </camel:sslContextParameters>...
...
  <to uri="jetty:https://127.0.0.1/mail/?sslContextParametersRef=sslContextParameters"/>
...

Configuring Jetty Directly

Jetty provides SSL support out of the box. To enable Jetty to run in SSL mode, simply format the URI with the https:// prefix---for example:

Code Block

	xml
	xml

<from uri="jetty:https://0.0.0.0/myapp/myservice/"/>

Jetty also needs to know where to load your keystore from and what passwords to use in order to load the correct SSL certificate. Set the following JVM System Properties:

until Camel 2.2

jetty.ssl.keystore specifies the location of the Java keystore file, which contains the Jetty server's own X.509 certificate in a key entry. A key entry stores the X.509 certificate (effectively, the public key) and also its associated private key.
jetty.ssl.password the store password, which is required to access the keystore file (this is the same password that is supplied to the keystore command's -storepass option).
jetty.ssl.keypassword the key password, which is used to access the certificate's key entry in the keystore (this is the same password that is supplied to the keystore command's -keypass option).

from Camel 2.3 onwards

org.eclipse.jetty.ssl.keystore specifies the location of the Java keystore file, which contains the Jetty server's own X.509 certificate in a key entry. A key entry stores the X.509 certificate (effectively, the public key) and also its associated private key.
org.eclipse.jetty.ssl.password the store password, which is required to access the keystore file (this is the same password that is supplied to the keystore command's -storepass option).
org.eclipse.jetty.ssl.keypassword the key password, which is used to access the certificate's key entry in the keystore (this is the same password that is supplied to the keystore command's -keypass option).

For details of how to configure SSL on a Jetty endpoint, read the following documentation at the Jetty Site: http://docs.codehaus.org/display/JETTY/How+to+configure+SSL

Some SSL properties aren't exposed directly by Camel, however Camel does expose the underlying SslSocketConnector, which will allow you to set properties like needClientAuth for mutual authentication requiring a client certificate or wantClientAuth for mutual authentication where a client doesn't need a certificate but can have one. There's a slight difference between the various Camel versions:

Up to Camel 2.2

The value you use as keys in the above map is the port you configure Jetty to listen on.

Configuring general SSL properties

Available as of Camel 2.5

Instead of a per port number specific SSL socket connector (as shown above) you can now configure general properties which applies for all SSL socket connectors (which is not explicit configured as above with the port number as entry).

Code Block

	xml
	xml

<bean id="jetty" class="org.apache.camel.component.jetty.JettyHttpComponent">
    <property name="sslSocketConnectorProperties">
        <map>

            <entry key="truststore"value="..."/>
        </map>
    </property>
</bean>

How to obtain reference to the X509Certificate

Jetty stores a reference to the certificate in the HttpServletRequest which you can access from code as follows:

Code Block
HttpServletRequest req = exchange.getIn().getBody(HttpServletRequest.class); X509Certificate cert = (X509Certificate) req.getAttribute("javax.servlet.request.X509Certificate")

Configuring general HTTP properties

Available as of Camel 2.5

Instead of a per port number specific HTTP socket connector (as shown above) you can now configure general properties which applies for all HTTP socket connectors (which is not explicit configured as above with the port number as entry).

Code Block

	xml
	xml

<bean id="jetty" class="org.apache.camel.component.jetty.JettyHttpComponent">
    <property name="socketConnectorProperties">
        <map>
            <entry key="acceptors" value="4"/>
            <entry key="maxIdleTime" value="300000"/>
        </map>
    </property>
</bean>

Obtaining X-Forwarded-For header with HttpServletRequest.getRemoteAddr()

If the HTTP requests are handled by an Apache server and forwarded to jetty with mod_proxy, the original client IP address is in the X-Forwarded-For header and the HttpServletRequest.getRemoteAddr() will return the address of the Apache proxy.

Jetty has a forwarded property which takes the value from X-Forwarded-For and places it in the HttpServletRequest remoteAddr property. This property is not available directly through the endpoint configuration but it can be easily added using the socketConnectors property:

Code Block

language	xml

<bean id="jetty" class="org.apache.camel.component.jetty.JettyHttpComponent">
    <property name="socketConnectors">
        <map>
            <entry key="8080">
                <bean class="org.eclipse.jetty.server.nio.SelectChannelConnector">
                    <property name="forwarded" value="true"/>
                </bean>
            </entry>
        </map>
    </property>
</bean>

This is particularly useful when an existing Apache server handles TLS connections for a domain and proxies them to application servers internally.

Default behavior for returning HTTP status codes

The default behavior of HTTP status codes is defined by the org.apache.camel.component.http.DefaultHttpBinding class, which handles how a response is written and also sets the HTTP status code.

If the exchange was processed successfully, the 200 HTTP status code is returned.
If the exchange failed with an exception, the 500 HTTP status code is returned, and the stacktrace is returned in the body. If you want to specify which HTTP status code to return, set the code in the Exchange.HTTP_RESPONSE_CODE header of the OUT message.

Customizing HttpBinding

By default, Camel uses the org.apache.camel.component.http.DefaultHttpBinding to handle how a response is written. If you like, you can customize this behavior either by implementing your own HttpBinding class or by extending DefaultHttpBinding and overriding the appropriate methods.

The following example shows how to customize the DefaultHttpBinding in order to change how exceptions are returned:

Wiki Markup
{snippet:id=e1\|lang=java\|url=camel/trunk/components/camel-jetty9/src/test/java/org/apache/camel/component/jetty/HttpBindingRefTest.java}

We can then create an instance of our binding and register it in the Spring registry as follows:

Code Block

	xml
	xml

<bean id="mybinding"class="com.mycompany.MyHttpBinding"/>

And then we can reference this binding when we define the route:

Code Block

	xml
	xml

<route><from uri="jetty:http://0.0.0.0:8080/myapp/myservice?httpBindingRef=mybinding"/><to uri="bean:doSomething"/></route>

Jetty handlers and security configuration

You can configure a list of Jetty handlers on the endpoint, which can be useful for enabling advanced Jetty security features. These handlers are configured in Spring XML as follows:

Code Block

	xml
	xml

<-- Jetty Security handling -->
<bean id="userRealm" class="org.mortbay.jetty.plus.jaas.JAASUserRealm">
    <property name="name" value="tracker-users"/>
    <property name="loginModuleName" value="ldaploginmodule"/>
</bean>

<bean id="constraint" class="org.mortbay.jetty.security.Constraint">
    <property name="name" value="BASIC"/>
    <property name="roles" value="tracker-users"/>
    <property name="authenticate" value="true"/>
</bean>

<bean id="constraintMapping" class="org.mortbay.jetty.security.ConstraintMapping">
    <property name="constraint" ref="constraint"/>
    <property name="pathSpec" value="/*"/>
</bean>

<bean id="securityHandler" class="org.mortbay.jetty.security.SecurityHandler">
    <property name="userRealm" ref="userRealm"/>
    <property name="constraintMappings" ref="constraintMapping"/>
</bean>

And from Camel 2.3 onwards you can configure a list of Jetty handlers as follows:

Code Block

	xml
	xml

<-- Jetty Security handling -->
<bean id="constraint" class="org.eclipse.jetty.http.security.Constraint">
    <property name="name" value="BASIC"/>
    <property name="roles" value="tracker-users"/>
    <property name="authenticate" value="true"/>
</bean>

<bean id="constraintMapping" class="org.eclipse.jetty.security.ConstraintMapping">
    <property name="constraint" ref="constraint"/>
    <property name="pathSpec" value="/*"/>
</bean>

<bean id="securityHandler" class="org.eclipse.jetty.security.ConstraintSecurityHandler">
    <property name="authenticator">
        <bean class="org.eclipse.jetty.security.authentication.BasicAuthenticator"/>
    </property>
    <property name="constraintMappings">
        <list>
            <ref bean="constraintMapping"/>
        </list>
    </property>
</bean>

You can then define the endpoint as:

Code Block
from("jetty:http://0.0.0.0:9080/myservice?handlers=securityHandler")

If you need more handlers, set the handlers option equal to a comma-separated list of bean IDs.

How to return a custom HTTP 500 reply message

You may want to return a custom reply message when something goes wrong, instead of the default reply message Camel Jetty replies with.
You could use a custom HttpBinding to be in control of the message mapping, but often it may be easier to use Camel's Exception Clause to construct the custom reply message. For example as show here, where we return Dude something went wrong with HTTP error code 500:

Multi-part Form support

From Camel 2.3.0, camel-jetty support to multipart form post out of box. The submitted form-data are mapped into the message header. Camel-jetty creates an attachment for each uploaded file. The file name is mapped to the name of the attachment. The content type is set as the content type of the attachment file name. You can find the example here.

Jetty JMX support

From Camel 2.3.0, camel-jetty supports the enabling of Jetty's JMX capabilities at the component and endpoint level with the endpoint configuration taking priority. Note that JMX must be enabled within the Camel context in order to enable JMX support in this component as the component provides Jetty with a reference to the MBeanServer registered with the Camel context. Because the camel-jetty component caches and reuses Jetty resources for a given protocol/host/port pairing, this configuration option will only be evaluated during the creation of the first endpoint to use a protocol/host/port pairing. For example, given two routes created from the following XML fragments, JMX support would remain enabled for all endpoints listening on "https://0.0.0.0".

Code Block

	xml
	xml

<from uri="jetty:https://0.0.0.0/myapp/myservice1/?enableJmx=true"/>

Code Block

	xml
	xml

<from uri="jetty:https://0.0.0.0/myapp/myservice2/?enableJmx=false"/>

The camel-jetty component also provides for direct configuration of the Jetty MBeanContainer. Jetty creates MBean names dynamically. If you are running another instance of Jetty outside of the Camel context and sharing the same MBeanServer between the instances, you can provide both instances with a reference to the same MBeanContainer in order to avoid name collisions when registering Jetty MBeans.
