Activiti initializes engine twice under WebLogic

mmaker1234 — Fri, 22 Jun 2012 08:24:45 GMT

Hello,I tried to run Activiti as a library in our application on WebLogic. What I observe is that Activiti finds the (single) configuration twice and initializes the engine twice. Here is an excerpt from the start log:INFO | 2012-06-22 08:19:30.182 | workflow.engine.WfEngineManager | startEngineLook

Seems like a valid improvement. I'll add this to trunk. To prevent this issue for now, maybe best to initialize the engine yourself, based on the configuration-file URL rather that just use the "default" initialization.

Hello Frederik,

Thank you for your quick reply!

We also thought on the approach to provide a configuration URL but here are our concerns:
- We prefer to non burden our administrators with file placements and application configuration tasks;
- Our application is deployed in different directories on the different servers (dev, test, prod, …) because some of them share the same file/operating system;
- WebLogic (as you can see in the provided log excerpt) unpacks the application .EAR(s) in different temporary directories.
As a consequence:
- It is not easy to "invent" an URL that to be valid on all environments where our application works
- We decided to deliver the Activiti configuration with our .EARs and to use the "default" initialization;

The original post was not a complaint (in contrast to http://forums.activiti.org/en/viewtopic.php?f=6&t=4121&p=16036 where I still expect an answer) - I only shared our experience. Actually the duplicated WF engine initialization is not a big issue for us:
- The first engine is stopped during the second initialization because the engine names appear to be equal;
- The initialization is fast enough (a couple of seconds, as you can see in the logs);
- As a result we have only one engine, which is the desired behavior;
- I already patched Activiti 5.9 and built it for our environment.
