Re: ClassLoader IllegalStateException
To turn it off, set reloadable="false" in the context definition of your app. I do not know where you have it defined, it might be tomcat's server.xml or context.xml of your app. I am not sure if it will work -- I have used applications listeners to stop the threads, which was very easy.

It might that it unloaded an app. You may turn off app unloading/reloading in serwer.xml. Or start and stop threads using listeners. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: ClassLoader IllegalStateException
ok, there could be plenty of things. but basically this is what is happening: one of your JDBC connections is being garbage collected. When this happens, it tries to close itself and in doing so, it needs to load a class. But the webapp is in a state where it has stopped (either been stopped, or reloaded) and throws an error. as mentioned earlier, more info on when this happens and in what circumstance.
