== Marshal EIP

Marshalling is the opposite of unmarshalling, where a bean is marshalled into some binary or textual format for transmission over some transport via a Camel link:https://github.com/apache/camel/tree/master/components[Components]. Marshalling is used in the same way as unmarshalling above; in the link:https://github.com/apache/camel/blob/master/docs/user-manual/en/dsl.adoc[DSL] you can use a DataFormat instance, you can configure the DataFormat dynamically using the DSL or you can refer to a named instance of the format in the link:https://github.com/apache/camel/blob/master/docs/user-manual/en/registry.adoc[Registry].

== Options

// eip options: START
The Marshal EIP supports 1 options which are listed below:

[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *dataFormatType* | *Required* The data format to be used |  | DataFormatDefinition
|===
// eip options: END

=== Samples

The following example unmarshals via serialization then marshals using a named JAXB data format to perform a kind of link:https://github.com/apache/camel/blob/master/camel-core/src/main/docs/eips/message-translator.adoc[Message Translator]

[source,java]
----
from("file://foo/bar").
  unmarshal().serialization().
  marshal("jaxb").
  to("activemq:Some.Queue");

[[DataFormat-UsingSpringXML]]
==== Using Spring XML

This example shows how to configure the data type just once and reuse it
on multiple routes

You can also define reusable data formats as Spring beans

[source,xml]
--------------------------------------------------------
<bean id="myJaxb" class="org.apache.camel.model.dataformat.JaxbDataFormat">
  <property name="prettyPrint" value="true"/>
  <property name="contextPath" value="org.apache.camel.example"/>
</bean> 
--------------------------------------------------------
