Is this possible with log4j?

Hello guys!

I had to rush from work today with out solving this issue.

I tried to configure my JBoss 5 in the jboss-log4j.xml to produce 2 separate log files.

1 for a ear (deployed in a separate, ear like company.ear)
1 for a war (deployed in a separate, war like company.war)

...running in the same JBoss.
Below is the snippets from jboss-log4j.xml.

The problem is that logging for the ear shall handle only all classes (from within the ear) that call the log with package starting with:
com.projectx

...and logging for the war shall handle only all classes (from within the war) that call the log with package starting with:
com.projectx.web

But what I end up with is one nice log file (web.log) with all logging from the war.
...AND a not so nice log file (server.log) with logging from both the ear and war.

I guess this is because of the package got the same starting.

I of course want them totally separated.
So if you got any solutions for this please let me know.
I hope I do not need to force the server to change the package-name.

Best regards
Fredrik
