Advanced AmazonSimpleDB configuration

If you need more control over the AmazonSimpleDB instance configuration you can create your own instance and refer to it from the URI:

from("direct:start")
.to("aws-sdb://domainName?amazonSDBClient=#client");

The #client refers to a AmazonSimpleDB in the Registry.

For example if your Camel Application is running behind a firewall:

AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey");
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("http://myProxyHost");
clientConfiguration.setProxyPort(8080);

AmazonSimpleDB client = new AmazonSimpleDBClient(awsCredentials, clientConfiguration);

registry.bind("client", client);

Dependencies

Maven users will need to add the following dependency to their pom.xml.

pom.xml
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-aws</artifactId>
    <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel (2.8.4 or higher).
