Hello!
I've tried to build war with jbpm, but I was stopped on deploypar process. maybe I do something wrong, it because of missing good (and full) tutorial with steps for duilding and depoying jbpm. UserGuide and articles on jboss wiki misse a lot of very important questions.
To deploy par I've used this ant target:

<target name="deploy.processes" description="deploys the jbpm processes">
 <taskdef name="deploypar" classname="org.jbpm.ant.DeployProcessTask">
 <classpath refid="classpath"/>
 </taskdef>
 <deploypar process="${build.dir}/simple.par"/>
 </target>

But during deploying process archive I've got exception:
[deploypar] 20:01:45,423 [main] INFO SessionFactoryImpl : building session factory
[deploypar] 20:01:48,393 [main] INFO SessionFactoryObjectFactory : Not binding factory to JNDI, no JNDI name configured
