The following data formats are currently supported

Unmarshalling

If you receive a message from one of the Camel Components such as File, HTTP or JMS you often want to unmarshal the payload into some bean so that you can process it using some Bean Integration or perform Predicate evaluation and so forth. To do this use the unmarshal word in the DSL in Java or the Xml Configuration.

...

from("file://foo/bar").
  unmarshal().serialization(). 
  marshal("jaxb").
  to("activemq:Some.Queue");

Using Spring XML

This example shows how to configure the data type just once and reuse it on multiple routes

{snippet:id=example|lang=xml|url=camel/trunk/components/camel-jaxb/src/test/resources/org/apache/camel/example/marshalAndUnmarshalWithRef.xml}

You can also define reusable data formats as Spring beans

<bean id="myJaxb" class="org.apache.camel.model.dataformat.JaxbDataFormat">
  <property name="prettyPrint" value="true"/>
  <property name="contextPath" value="org.apache.camel.example"/>
</bean>
