Hi All
Please HELP!! new bee :|
I have created my own human task process but i cant get it to start using eclipse when i
debug it, what could be the issue?
I have tried everything i could think of , "even compared it with a the evaluation
process"

Take a look at HumanTaskExample in jbpm-examples module for a start:
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-examples/src/main/jav...
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-examples/src/main/jav...
Looks like you are never creating your TaskClient

Hi,
you have misspelled the user name. So update the line
params.put("employee", "Krisv");
to
params.put("employee", "krisv");
Regards
