[rules-users] Null pointer exception when adding drools to existing project

I am having too many issues integrating drools into my existing code base, bcos I am unfamiliar with drools/jboss/maven. I have large code base and trying to add drools to it. I was able to run helloworld-drools from eclipse, but I cannot make it work when I add drools to existing project(File ->new ->drools->rule resource). I could compile, but I get null pointer exception when I run it (makes me believe that it has to add something to pom.xml or involved with other setup) I described my entire problem below. http://stackoverflow.com/questions/21466716/unknown-kiesession-name-in-dr... <http://stackoverflow.com/questions/21466716/unknown-kiesession-name-in-dr... One of the threads in this forum speaks about wiki; I appreciate pointing me to any specifics in resolving this. -- View this message in context: http://drools.46999.n3.nabble.com/Null-pointer-exception-when-adding-droo...
