Using the SOA-P 5 and the Smooks Editor for an action chain. The Editor will not map from XML to Java. Here are the steps followed:

1. Select XML as the input type and add an XML example file as the input data for the model(I used order.xml from the SOA-P examples)

2. Click on Input Task and add a Task , and select Java Mapping.

3. In the Selected Task Details pane, you should be able to right click and add a Java Class. This would allow mapping from XML and the new Java Class selected. Please see figure 2.7 of the Smooks Editor documentation: http://docs.jboss.org/tools/3.1.0.CR2/en/jboss_smooks_plugin_ref_guide/html_single/index.html
