[jboss-dev-forums] [Design of POJO Server] - Re: JBAS-6061 or weird nested jar

[rzumwalt]

I was seeing this same problem as Luc in CR2, but the original fix for this issue only partially resolved my problem. Our archive file actually includes sqljdbc.jar in it's WEB-INF/lib directory. We do this because we ship an EAR file out to customers who then install it on one of the app servers we support (JBoss being one of them). If I remove the JAR from our EAR and place it in the server's lib directory, then everything works just fine. I'd prefer to be able to deploy our EAR file with the jar inside of it since it reduces the number of steps to deploy our app.

the stack trace I see is below:

I assumed from the comments for the fix that the intent was to be able to specify additional exception handlers for problematic jars in conf/bootstrap/vfs.xml when needed. I tried adding an additional exception handler (that used the server's tmp/vfs-nested.tmp/ directory as the key since that is where the JAR is read from when deploying) to the vfs.xml file but that did not work. Perhaps I did something wrong, here was the entry I added to vfs.xml


  ${jboss.server.home.url}tmp/vfs-nested.tmp/
