Chapter 56. Castor DataFormat (deprecated)

from("direct:order").
  marshal().castor().
  to("activemq:queue:order");

For example the following uses a named DataFormat of Castor which uses default Castor data binding features.

CastorDataFormat castor = new CastorDataFormat ();

from("activemq:My.Queue").
  unmarshal(castor).
  to("mqseries:Another.Queue");

If you prefer to use a named reference to a data format which can then be defined in your Registry such as via your Spring XML file. e.g.

from("activemq:My.Queue").
  unmarshal("mycastorType").
  to("mqseries:Another.Queue");

If you want to override default mapping schema by providing a mapping file you can set it as follows.

CastorDataFormat castor = new CastorDataFormat ();
castor.setMappingFile("mapping.xml");

Also if you want to have more control on Castor Marshaller and Unmarshaller you can access them as below.

castor.getMarshaller();
castor.getUnmarshaller();

The following example shows how to use Castor to unmarshal using Spring configuring the castor data type

<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
  <route>
    <from uri="direct:start"/>
    <unmarshal>
      <castor validation="true" />
    </unmarshal>
    <to uri="mock:result"/>
  </route>
</camelContext>

This example shows how to configure the data type just once and reuse it on multiple routes. You have to set the <castor> element directly in <camelContext>.

<camelContext>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
  <dataFormats>
    <castor id="myCastor"/>
  </dataFormats>

  <route>
    <from uri="direct:start"/>
    <marshal ref="myCastor"/>
    <to uri="direct:marshalled"/>
  </route>
  <route>
    <from uri="direct:marshalled"/>
    <unmarshal ref="myCastor"/>
    <to uri="mock:result"/>
  </route>

</camelContext>

The Castor dataformat supports 9 options which are listed below.

To use Castor in your camel routes you need to add the a dependency on camel-castor which implements this data format.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-castor</artifactId>
  <version>x.x.x</version>
</dependency>
