Problems with Activiti 5.12 logging in WebLogic

[mmaker1234]

Hello Activiti developers,

I'm trying to collect the minimum set of support libraries Activiti 5.12 requires. Currently I found the libraries set to run seamlessly my standalone environment (in Ant).

The problem is that when I package Activiti and the set of supporting libraries with my application and deploy it on WebLogic I receive the following error:

Exception while initializing process engine: org/apache/commons/logging/LogFactory

The release notes for 5.12 mentioned that Activiti and its libraries were migrated to SLF4J.

Do I still need to provide commons-logging for Spring together with the SLF4J for Activiti?

See this: http://activiti.org/userguide/index.html#loggingConfiguration

Important note when using a container with commons-logging in the classpath: In order to route the spring-logging through SLF4J, a bridge is used (see http://www.slf4j.org/legacy.html#jclOverSLF4J). If your container provides a commons-logging implementation, please follow directions on this page: http://www.slf4j.org/codes.html#release to ensure stability.

Maybe that can help…

Hello Frederik,

Thank you for the point. I had missed an important information. Again 

Thankful,
