Custom ClassLoader and Groovy Scripts

zoikks1 — Sun, 08 Mar 2015 12:56:19 GMT

I have created a workflow framework that utilizes Activiti 5.16.3 as the workflow engine. The framework runs in WebLogic 12c and is an EJB environment with Spring injections. Recently, I created a specialized classloader that I use to split workflow delegates/objects outside of the framework class

Afaik, that doesn't propagate to the scripting engine … as that is done by the JDK itself. I'm actually not sure if that will work anyway.

Can't you get the classloader in the script itself? The processEngineConfiguration should be reachable, even in a script (or make a reusable utility class for it …)

Thanks for the reply.

If retrieving the ProcessEngineConfiguration from the workflow is possible, what would be the syntax to retrieve it in the script node? With that question asked, what would one do to modify the runtime classloader for Groovy?

Thanks,

the syntax is the same as in a JavaDelegate: execution.getEngineServices().getProcessEngineConfiguration

I don't know about that …
