org.jboss.netty.internal.LoggerConfigurator is already installed error

[Ross Lambert]

Figured it out... Netty creates a bean for logging in META-INF/jboss-beans.xml:

  <bean name="org.jboss.netty.internal.LoggerConfigurator"
        class="org.jboss.netty.container.microcontainer.NettyLoggerConfigurator" />

Changing the name to something unique to each servlet took care of the problem.

Maybe this was obvious, but I've been using Netty as a black box and haven't really cracked the code yet (darn good black box, BTW... thanks again, Tristin). Hopefully this helps somebody else who has the same issue.

The plot thickens...

I got the bright idea to remove the old servlet and install the new... and the it worked! The new servlet that was throwing the IllegalStateException is now installing with no problems. So naturally, I tried to reinstall the old servlet, and it croaked. 

Does this mean I can only install Netty once inside JBoss?  Is there an easy way around this?

Thanks,

Gentlefolks,

I have a servlet that uses Netty to talk an external bit of software. No big deal, works fine.

What has me baffled is that now when take the same code and build a different servlet and deploy it under JBoss 5.1, I get this error:

DEPLOYMENTS IN ERROR:
  Deployment "vfszip:/C:/jBoss/server/default/deploy/dems-gui.war/" is in error due to the following reason(s): java.lang.IllegalStateException:
org.jboss.netty.internal.LoggerConfigurator is already installed.

The tale gets weirder still: If I remove netty-3.2.4.Final.jar from the deployed .war, everything is fine! The servlet will blow if I make any Netty calls, of course, but it deploys fine and can do everything else OK.

I have tried deploying to two different servers and got the same result, so it does not appear to be anything peculiar to a single JBoss instance. I have also Googled this issue and searched the archives and see nothing relevant. The error message is so long that it a bit hard to narrow the search, so I could have easily missed something.

Does anybody have any ideas? I'm embarrassed to say how much time this has cost me already. :-)

Thanks,

== Ross ==
