JiBX

XStream

XStream is a Data Format which uses the XStream JiBX library to marshal and unmarshal Java objects to and from XML.

// lets turn Object messages into XML then send to MQSeries
from("activemq:My.Queue").
  marshal().xstreamjibx().
  to("mqseries:Another.Queue");

XMLInputFactory and XMLOutputFactory

The XStream library uses the javax.xml.stream.XMLInputFactory and javax.xml.stream.XMLOutputFactory, you can control which implementation of this factory should be used.

The Factory is discovered using this algorithm:
1. Use the javax.xml.stream.XMLInputFactory , javax.xml.stream.XMLOutputFactory system property.
2. Use the lib/xml.stream.properties file in the JRE_HOME directory.
3. Use the Services API, if available, to determine the classname by looking in the META-INF/services/javax.xml.stream.XMLInputFactory, META-INF/services/javax.xml.stream.XMLOutputFactory files in jars available to the JRE.
4. Use the platform default XMLInputFactory,XMLOutputFactory instance.

How to set the XML encoding in Xstream DataFormat?

From Camel 1.6.3 or Camel 2.2.0, you can set the encoding of XML in Xstream DataFormat by setting the Exchange's property with the key Exchange.CHARSET_NAME, or setting the encoding property on Xstream from DSL or Spring config.

Please note that marshaling process can recognize the message type at the runtime. However while unmarshaling message from XML we need to specify target class explicitly.

// lets turn XML into PurchaseOrder message
from("mqseries:Another

from("activemq:My.Queue").
  marshalunmarshal().xstream("UTF-8"jibx(PurchaseOrder.class).
  to("mqseriesactivemq:AnotherMy.Queue");

JiBX Spring DSL

JiBX data format is also supported by Camel Spring DSL.

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

  <!-- Define data formats -->
  <dataFormats>
    <jibx id="jibx" unmarshallClass="org.apache.camel.dataformat.jibx.PurchaseOrder"/>
  </dataFormats>

  <!-- Marshal message to XML -->
  <route>
    <from uri="direct:marshal"/>
    <marshal ref="jibx"/>
    <to uri="mock:result"/>
  </route>

  <!-- Unmarshal message from XML -->
  <route>
    <from uri="direct:unmarshal"/>
    <unmarshal ref="jibx"/>
    <to uri="mock:result"/>
  </route>

</camelContext>

Dependencies

To use JiBX To use XStream in your camel routes you need to add the a dependency on camel-xstreamjibx 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-xstream<jibx</artifactId>
