I just added an example for a Web Service invocation with simplistic data flow: http://fisheye.codehaus.org/changelog/activiti/?cs=899

Could you please have an eye on XML namespaces. We will need them as soon as multiple Web Services are used in one process definition.

I added two more examples for complex data flow using UEL and XPath as expression language:

• Document web service task

postponed to 5.1

the reason is that we need to work out how a web service example will be presented in the distribution.
this should be done in a separate example project. and with separate library dependencies.
similar as now features jpa and groovy are done.

This release I'll add the cxf test as an example to the distribution. This includes ensuring that the libraries are shipped and that the dependencies are listed in a text file and that the example libs can be populated using that text file.

Postponing to Later as we first need someone to fix the CXF test case.

The test is fixed and included in build now: https://fisheye.codehaus.org/changelog/activiti/?cs=2024 (the problem was that some id refs have to be qualified)

A web service task was already present in Activiti 5.6
