[githikashree]

Hi All,

I am getting exception(.registerWorkItemHandler() method not supported) when register work item handler with ksession created through RemoteRuntimeEngine again created through RemoteRestRuntimeFactory.

Please help on this issue.

Please let me know, is there a way to solve this issue or any other alternative way or workaround it would help me lot.

Thanks,

RemoteRuntimeEngine is actually a wrapper that is meant to simplify execution of the process remotely. Although it does implement main interfaces (KieSession, TaskService) it does not provide complete implementation for it as they are not matching the execution behavior. Please note that when you interact with engine remotely you interact with already configured engine, so handlers, listeners, etc should be registered on server side and not on client side as how would you like transfer that class instance that you create locally to the server??

Hi Maciej,

I'm facing the same issue, how can I register handlers on server side?
