Subject: Re: classloader problem
Hi A Srivani,
I this is not a problem with tomcat, instead it is a problem with your
deployment.
You are putting commons-discovery.jar, and this JAR file is storing a
reference to the webapp classloader.
When the app is reloaded, the old webapp classloader gets invalidated,
and a new one is created.
but since you put the the JAR in shared/lib that instance doesn't get
reloaded, and is now holding a reference to the wrong classloader.
This is simple a deployment problem, the correct way to deploy it is to
have it in WEB-INF/lib or fix the commons-discovery code.
