Error during web application execution on JBoss 4.0.1...

[pavelkrupets]

I haven't changed anything in JBoss configuration and I use server/all deployment. I added web application with element in web.xml. Application is deployed through JBoss farm.

There are 2 JBoss instances running one on Windows Server 2003 and another on Linux.

When I access web application through server1 I've got following error on server2 (the same on server1 if I access web application through server2)

Also TomcatClusteringCache.printDetails() prints following lines:

/JSESSION

/D76LReQ+j0nUTjMiUtXJ8g**

Don't know why this error can occur. Can anyone help me?
