Problems running the simple demo process

When I try to run the simple demo process in Eclipse, I get the follow message in the console:

java.lang.IllegalArgumentException: Could not connect task client

I have gone through setup a few times to make sure I did not miss anything. Ideas?

I figured out that the problem was with start.human.task. This was not being started correctly because the h2.jar file was not located in ${install.home}/db/driver directory. Once I added the jar to the directory, start.human.task loaded fine and I was able to run the simple demo process.

Hi team,
I do have the same issue but the h2.jar is correctly placed in the location.
Any idea to resolve this?

Thanks

If you try to run ant start.human.task inside the jbpm-installer, does it start up the human task service correctly or does it give any other useful output why it might not start?
