Log4jRepositorySelector undeployment problem

perrucci Jun 7, 2006 2:24 PM

Hi all,

I'm trying to separate log4j logs of my web application running inside jboss 4.0.4GA and I tried to use the Log4jRepositorySelector found here

http://wiki.jboss.org/wiki/Wiki.jsp?page=Log4jRepositorySelector

It seems that it works like a charm until the webapp undeployment.
At this point I get a lot of exception starting with:

I'm also facing the same problem. Anobody from jboss can help us resolve this? Looks like something related to cleaning up/destroying some logger related objects.

Though I couldn't find the clean solution, I was able to get around the problem.
The problem was for some reason, the class variable "repositories" didnt get initialized properly though its been assigned value(new Hashmap()) while declaring it.

I had to do 2 changes here to get around:
1.Made the "defaultRepository" a instance variable instead of static one and assigned it a value in the place where its declared.
private LoggerRepository defaultRepository = LogManager.getLoggerRepository();

2.In the method getLoggerRepository, I added a bullet proof code before accessing repositories table.
if ( repositories == null )
return defaultRepository;

Hope this will help to avoid throwing exceptions while undeploying.

I also ran into this problem and I am sorry to say phanir's solution does not work for me. I still get the same error.
I did find some additional information on this problem at:
