Hello Everyone,
I am a newbie to tomcat. I had deployed a war file in tomcat. When i
start tomcat i get the following errors. To give you more details. I am
using gridsphere portlet container. I am deploying a portlet in
gridsphere using tomcat. Please look below for error details.
I guess the problem is with web.xml. I had also attached web.xml,
portlet.xml, layout.xml in the bottom.
Thanks
