Hello Huisheng,

thanks for your answer.
I installed jBPM via demo.setup.jboss.

In my project I'm using the create.and.deploy.pois target of the following build.xml. I copied the build.xml from the example project. But I had to modify it a little bit, because the original build.xml creates an example.bar which contains *.java - Files and not *.class - Files. So I changed it and my pois.bar contains *.class - Files.  

<?xml version="1.0" encoding="UTF-8"?>

<project name="jbpm.pois">
