Hi,

I have deployed my process plugin code. Trying to start process. Getting below error.

Hi Suhaib,

could you give more details? How do you deploy your project?
The error is happening in task listener, right? Is your BPMN model and Task Listener deployed within the same deployment unit?

Can you post your Task listener code here?

Hi @SuhaibSultan,
Have you found a solution? I have the same problem and I think it could be related to the type of engine you are using: In a shared engine you have to deploy the plugin in the tomcat/lib folder, where spring jars are not present. So a plugin cannot use spring framework.
Alternatively you have to put spring jars also in the tomcat lib folder, but I don’t know what downside can have this solution.

Hi Mizar01 and Suhaib,

Were you able to resolve this issue?

Thanks,
