[jbpm-users] [JBoss jBPM] - jBPM4 Hello World example - null pointer exception

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.
