Hello,
I 'm getting an InstanceAlreadyExistsException (exception trace below) when
redeploying a Wicket app (1.3.1) in Websphere test environment. I didn't
have this problem when running Wicket 1.2-rc1. When doing a regular stopping
and starting of the App server the application starts up fine.
I'm using the WicketServlet (not the Filter) and I'm integrating with Spring
using the annotation method.
Any ideas? Something I'm doing wrong, or a work around maybe?
I will provide more information if required.
Thanks,
Nick
