Created a Process Model with a Data item of type 'XML Document' named 'InputXml'. Connected the type to an Application activity that writes the XML to the console.

Adapted Wen Service example Java application found in ws-example-java.zip:
http://help.eclipse.org/luna/topic/org.eclipse.stardust.docs.dev/html/examples/ws-client-java/readme.html?cp=61_10_1_0
to start the process with XML as a parameter.

Attached the Process Model and a Java class, modified from example mentioned above, see method startProcess(), to setup the parameters.

The server side fails with an exception: 
15:46:25 ERROR [80-exec-33] DataFlowUtils             - Unmarshaling of DataValue (InputXml) failed. Type not supported

Hello Roger,

As the "XMLDocument" data is a depricated dataType, i would encourage to use the External Reference structured data type instead, which is equivalent to the XML Data type.

Please refer the "Using External XSD Types" section from following documentation link:
http://help.eclipse.org/mars/topic/org.eclipse.stardust.docs.dev/html/handbooks/modelling/data-integration/structured-data/struct-type-def.html?cp=72_7_0_1_1_0

If you would still like to make use of the XMLData type data, please try one of the following approaches to set the XMLData:

1. Use a Primitive Data Type with default value set to the XML String and map the data in the InData Mapping.
2. Use a Java Application and set out-datamapping which passes the xml content into the xml document data.

Attached are the models for the same.

-Regards
Ashish
