jBPM4 Hello World example - null pointer exception

[dwise1]

I am working through the jbpm4 hello world example,
I am getting a null pointer exception when executing:

repositoryService.createDeployment()
.addResourceFromClasspath("helloWorld.jpdl.xml")
.deploy();

Any suggestions?
Also, is there a book or an article that goes into depth on how to set up jbpm4? I am a beginner to jbpm and it would help me alot to get something like this to work with.

I am trying the directions from the above suggestion ... "Refer this link ... http://twger.blogspot.com/2009/08/jbpm-4.html "

In Eclipse I do not have the option to create a new "JBoss jBPM - Process Project". The only option that is available under JBoss jBPM is "jBPM 4 Process Definition". Any suggestions on what could be wrong with my Eclipse that would not allow me to select a Process Project for jBoss jBPM?
Thanks!

And use some search functionality regarding your second question.... (answer: not needed to have a process project)
