Reproduce steps:
Simple Servlet or EJB process application bundled as WAR file with a dependent JAR bundled in the WAR with the application (maven-managed dependencies). JavaDelegate can refer to classes in bundled JAR but groovy script task can not find classes in bundled JAR.
Problem:
Script task throws exception as it can not find referenced class in dependent JAR
Expected behavior:
Script task should be able to refer to classes in dependent library JAR, as the JavaDelegate does
Hints (optional):
I began this exploration on the camunda-bpm-users google group and have had several exchanges with Daniel Meyer already. Link here: https://groups.google.com/forum/#!topic/camunda-bpm-users/TrZas5rtRco
Two workarounds for this issue are to either put the dependent JAR in the lib/ext directory of my WAS app server, or to explicitly load the required class from my groovy script. Neither of these solutions is ideal and Daniel suggested filing a bug report

[CAM-2857] Cannot reference process application provided classes inside a Groovy Script

Hi Sebastian
This issue is not critical for me. It was critical to have my library application-scoped as opposed to globally shared in lib/ext in my application server, but loading the class explicitly from my groovy script is an acceptable workaround.
When I execute the process in an embedded-engine scenario, the groovy script is able to find the required class so it seems that the groovy engine does not have access to the application context when run in a shared-engine scenario.
Anyhow, I just created this ticket at Daniel's suggestion so the issue can be tracked. It is not critical.
Thank you.

Hi Bryan,
Thanks for pointing out this issue. We are currently not aware of a way to fix this issue of the groovy script engine or if we can actually even fix this on our side.
I want to ask you how important this issue is for you?
Cheers,
Sebastian
