Hi, I have installed tomcat 4.1, eclipse 3.2 , a sysdeo plugin and then I dropped in the struts-example war file. When I start up tomcat I get the following error.

Additionally, I can not get to the struts-example page. It shows it as expanded in the webapps but it is not listed on my admin page of tomcat. I am not sure if that is a related problem or not. I have tried searching for answers but the ones I find or related to using log4j but I am not using that (unless it is part of the packages I installed.) I have even deleted everything and re-installed but no luck yet. Thanks for the help
