Hi!
I have a tomcat server with my webapp.
In my tomcat/lib, i have a "commons-logging-1.0.4.jar".
And i upgrade birt from v2.5 to v3.7. Now, i am having this error:
HTTP Status 500 - An internal error occurred: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy. You have more than one version of 'org.apache.commons.logging.Log' visible, which is not allowed. (Caused by org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy. You have more than one version of 'org.apache.commons.logging.Log' visible, which is not allowed.)
Did some one see that problem by using Birt?

It's because 3.7 made the move to a POJO runtime. You could try deleting the version that is in BIRT and see if you run into any issues. BIRT should pick up the other version in the classpath. If you have issues with something not working properly, after this, there is an option in 3.7.2+ to use the OSGi runtime, which is like the one back in 2.5. This would solve the issue, for sure.
