How to use jar files in guvnor?

created by xealous in jBPM - View the full discussion

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
