    Async call using ExecutorService is getting class not found when server is restarted

    Jim Rennie Newbie

      Using JBPM6 and I'm trying to setup an async call by defining my command in the kie-wb-deployment-descriptor.xml file.

       

      So I define command like this:

          <work-item-handler>

            <resolver>mvel</resolver>

            <identifier>new org.jbpm.executor.impl.wih.AsyncWorkItemHandler(org.jbpm.executor.ExecutorServiceFactory.newExecutorService(javax.persistence.Persistence.createEntityManagerFactory("org.jbpm.domain")), "com.jimrennie.errorhandling.workitemproject.workitems.MyFirstCommand")</identifier>

            <parameters/>

            <name>MyFirstAsync</name>

          </work-item-handler>

       

      Through business central I added my workitems project into the artifact repository, added it as a dependency in my jbpm project, and added it to my WorkDefinitions.wid file. All of this works great. The process executes as expected. The issue I'm running into is when I restart my server while the async process is still running, I get "Unknown Command implemenation with name 'com.jimrennie.errorhandling.workitemproject.workitems.MyFirstCommand'" when the process attempts to start up again. Once the server is started I can requeue the job and it runs without issue. Is this a bug or am I doing something wrong.

        • 1. Re: Async call using ExecutorService is getting class not found when server is restarted
          Jim Rennie Newbie

          Fixed the issue by defining the my async workItemHandler in each project instead of for the whole execution server. I suppose it makes sense why this didn't work since I added the dependency to "MyFirstCommand" in my project, but the async workItemHandler was defined for the whole execution server. On an additional note, I now pass in the entityManagerFactory as a parameter to the newExecutorService method instead of creating a new one every time. Not sure why the developer guide code sample creates a new EntityManagerFactory for every async work item handler.
