Hi everyone,
I've been searching for days and still couldn't find good tutorials on jbpm5. I have a hard time using external jars in my project. Any help is appreciated :)
Here are the steps I took;
I have a CreateProject.jar file that I need to use with my process so that I can write stuff to the database via a web service.
I have com.deneme.CreateProject class in it that I import and use in my script task.
I've uploaded it as POJO model jar
Package validation and build is successful but I don't see my process in jbpm-console and jboss server log has the following:

Moreover, is using script task is fine or should I use another approach?
Thanks in advence
