Camel Data Format

JAXB

Using the Java DSL
For example the following uses a named DataFormat of jaxb which is
configured with a number of Java package names to initialize the
JAXBContext.
DataFormat jaxb = new JaxbDataFormat("com.acme.model");
from("activemq:My.Queue").
unmarshal(jaxb).
to("mqseries:Another.Queue");
You can if you prefer 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("myJaxbDataType").
to("mqseries:Another.Queue");

Using Spring XML
The following example shows how to use JAXB to unmarshal using Spring
configuring the jaxb data type
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:start"/>
306 DATA FORMAT APPENDIX
<unmarshal>
<jaxb prettyPrint="true" contextPath="org.apache.camel.example"/>
</unmarshal>
<to uri="mock:result"/>
</route>
</camelContext>
This example shows how to configure the data type just once and reuse it on
multiple routes. For Camel versions below 1.5.0 you have to set the <jaxb>
element directly in <camelContext>.
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<dataFormats>
<jaxb id="myJaxb" prettyPrint="true" contextPath="org.apache.camel.example"/>
</dataFormats>
<route>
<from uri="direct:start"/>
<marshal ref="myJaxb"/>
<to uri="direct:marshalled"/>
</route>
<route>
<from uri="direct:marshalled"/>
<unmarshal ref="myJaxb"/>
<to uri="mock:result"/>
</route>
</camelContext>

Partial marshalling/unmarshalling
This feature is new to Camel 2.2.0.
JAXB 2 supports marshalling and unmarshalling XML tree fragments. By
default JAXB looks for @XmlRootElement annotation on given class to operate
on whole XML tree. This is useful but not always - sometimes generated code
does not have @XmlRootElement annotation, sometimes you need
unmarshall only part of tree.
In that case you can use partial unmarshalling. To enable this behaviours you
need set property partClass. Camel will pass this class to JAXB's
unmarshaler.
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:marshal"/>
<marshal>
<jaxb prettyPrint="false" contextPath="org.apache.camel.example"
partClass="org.apache.camel.example.PurchaseOrder"

 Multiple context paths
It is possible to use this data format with more than one context
path. You can specify context path using : as separator, for
example com.mycompany:com.mycompany2. Note that this is
handled by JAXB implementation and might change if you use
different vendor than RI.

fragment="true"
partNamespace="{http://example.camel.org/apache}po" />
</marshal>
<to uri="mock:marshal"/>
</route>
<route>
<from uri="direct:unmarshal"/>
<unmarshal>
<jaxb prettyPrint="false" contextPath="org.apache.camel.example"
partClass="org.apache.camel.example.Partial" />
</unmarshal>
<to uri="mock:unmarshal"/>
</route>
</camelContext>
For marshalling you have to add partNamespace attribute with QName of
destination namespace. Example of Spring DSL you can find above.
