How to create humantask in JBPM 5.4 without starting jbpm task server

[suraj.bahl.50]

Hi,

I want to integrate JBPM5 with one of our existing web application hosted on Websphere (WAS). In workflow we have some human tasks on which we want users to take action though existing application instead of JBPM console. Is it possible to create a human task in JBPM 5 without running the task service? Is there an example which can show me how to start a task through POJO & JBPM API's (as it was in JBPM older versions). Once user takes some action then using JBPM API's we should be able to execute the task further.

you need to use task service in the local mode with combination of Local task service handler. Here is a test case illustrating it.

Thanks Maciej for looking into this, I tried it with JBPM6 and it was very straightforward in that. I was able to start & execute human tasks using the TaskService provided by RunTimeManager. i think i'll go with jbpm6, one question if i dont want to enable persistence then i need to pass my own implementation of WorkItemHandler to RunTimeManager. Are there any default implementations provided by JBPM or any sample you can share?

Hi,

It looks like there is some issue with jBPM version 6.1. i removed 6.1 and re-installed 6.0 now it is working fine.

Thanks,

I believe the problem is that you don't have jbpm-human-task.jpa on your classpath and thus the transaction interceptor and jpa persistence is not available.
