1. Re: In what order are classes loaded?
alesj Oct 20, 2010 1:02 PM (in response to sannsims)The common/lib/ is loaded before your app, so you should see them.
Perhaps you have some parent-child issue, as war's use child-first class lookup notion?

2. Re: In what order are classes loaded?
sannsims Oct 20, 2010 2:40 PM (in response to alesj)Hi Ales,
Thanks for your quick reply! Is there a way I can debug this issue; determine if the war is being loaded in the same class loader? The classes should only exist in the common/lib directory.
Thanks in advance for your help!

Normally it's best not to add your dependencies on the common/lib, ideally you would leave the common/lib with the stock jars, and add you custom jars in your <server_name>/lib folder or more specific jars in your WEB-INF/lib (for War applications).
JBoss loads the jars from common/lib, then the jars in <server_name>/lib and then the ones in the deploy folder, you can change the behavior using jboss-web.xml (or jboss-app.xml in ear) specific configurations. These configurations are normally only necessary if you want to bundle previous or conflicting jars with your application, for example an older or newer version of hibernate.
It's possible in your case that you might have added some other libs to the classpath that are conflicting with current libs in other levels, if you could post a stack trace, it could be easier to track exactly what's happening.

4. Re: In what order are classes loaded?
sannsims Oct 21, 2010 4:49 PM (in response to fstani)Thanks fstani for your reply. I needed to put my jar file in the common/lib directory so that it would be visible to other applications. For example, I have a web application in the default directory and another one in the web directory; both will need visibility to the jar file in common/lib. It seems I have this issue resolved though, I was missing some dependencies required by my jar file.
