marshal— Converts a high-level data format to a low-level data format.

unmarshal — Converts a low-level data format to a high-level data format.

Java serialization—Enables you to convert a Java object to a blob of binary data. For this data format, unmarshalling converts a binary blob to a Java object, and marshalling converts a Java object to a binary blob. To read a serialized Java object from an endpoint, SourceURL, and convert it to a Java object, you use a rule like the one shown in Example 7.2.

<camelContext id="serialization">
  <route>
    <from uri="SourceURL"/>
    <unmarshal>
      <serialization/>
    </unmarshal>
    <to uri="TargetURL"/>
  </route>
</camelContext>

JAXB—Provides a mapping between XML schema types and Java types (see https://jaxb.dev.java.net/). For JAXB, unmarshalling converts an XML data type to a Java object, and marshalling converts a Java object to an XML data type. Before you can use JAXB data formats, you must compile your XML schema using a JAXB compiler to generate the Java classes that represent the XML data types in the schema. This is called binding the schema. After the schema is bound, you define a rule to unmarshal XML data to a Java object, using code like Example 7.3.

<camelContext id="jaxb">
  <route>
    <from uri="SourceURL"/>
    <unmarshal>
      <jaxb prettyPrint="true" contextPath="GeneratedPackageName"/>
    </unmarshal>
    <to uri="TargetURL"/>
  </route>
</camelContext>

XMLBeans—Provides an alternative mapping between XML schema types and Java types (see http://xmlbeans.apache.org/). For XMLBeans, unmarshalling converts an XML data type to a Java object and marshalling converts a Java object to an XML data type. To unmarshal XML data to a Java object using XMLBeans, you use code like the Example 7.4.

<camelContext id="xmlBeans">
  <route>
    <from uri="SourceURL"/>
    <unmarshal>
      <xmlBeans prettyPrint="true"/>
    </unmarshal>
    <to uri="TargetURL"/>
  </route>
</camelContext>
