depends how you deploy your processes and rules. If you simply use jbpm.console.directory then only processes are read from that location and rules are not. You could use Guvnor for that and import both process and rule there. That will make both rules and processes available for the runtime inside console.

Hello, Maciej !

That is the point!
I cannot see an instance of Sample process as completed in JBPM-console although it allows me to start a new one and does not show any errors.
It says "All: 0 instances of Sample process".
Person class is on path, I suppose: d:\jbpm\dependencies\Person.jar
I did that after I put Person.jar in d:\jbpm\dependencies:
ant clean.demo
ant install.demo.noeclipse

But there are not other messages in server.log while I start an instance except those:

So I am in doubt is an instance created or not?

Not sure if this helps, but I would debug it by putting some script tasks in your process which just print something like "Got here" so you at least know the process is being run. If the process is being run, but you are not seeing the "Person " part, then you know it's something with the rule or the way you are calling the rule.

HTH.

+1 doboss

alternatively you can take a look at data base tables (nodeinstanelog)

I think that the instance is created and since it has no wait state it finishes in the same thread it was started so console won't show it as active.

Just looked at the process again, I think what happens is that the process you insert is null. And this is bacause you set p (which is a process variable) in the script but that is only assigning the value but does not set it as process variable. if you replace the first script with following lines I think the rule will be fired:
*p = new Person("john", 19);*
kcontext.getProcessInstance().setVariable("p", p);

I don't know about the casting, but I don't think the jar needs to be in the Guvnor path, as the Guvnor is just a repository. I think you want to make sure the jar is in the path of the application running the process...
