then i have to restart the application (or websphere server) and works well again.

which can be the problem?

thanks in advance,
César.

Have you found a fix for this? It is very annoying--and becoming expensive--to have to restart the application server to deploy a change.

[cesar]

Hello,
No, i have to restart the server.
Saludos,
César.

I was trying to run a simple application in debug mode to pinpoint exactly where the error occurs. In debug mode within WSAD, the error didn't occur at all!

[joeparks]

Although the ContextLoaderServlet fails on a restart of the web application, the Struts ContextLoaderPlugin succeeds!

If I remove the root context (by disabling the ContextLoaderServlet) and move all of the bean definitions to the action-servlet.xml descriptor, I am able to refresh the classes/jars used by the web application without having to restart the application server.

Hello,

Struts ContextLoaderPlugin? i use spring mvc, i can replace ContextLoaderServlet with this plugin and works?

Cesar.

I may have posted too quickly. I was using the WAS 5.1 test environment; not WAS 4.0.
I went back and tested with the 4.0 Test Environment, and the workaround did not work around the problem.
It probably wouldn't help you much, though, if you aren't using Struts.

Sorry.

It is good to note, though, that the problem does not occur with WAS 5.1 (JDK 1.4.1).

thanks anyway, i hope that upgrade to was 5.1 early...

Saludos,
César.

same thing for me... it doesn't seem to be container-related, I'm using orion as my container and getting this when i redeploy my app
