My comapany recently upgraded to Tomcat 5.5.26 from Tomcat 4.0.4. I have been put in charge of getting our applications up and running in the new version. I am trying to run tests on the server in Tomcat to see if it is accepting .jsp and servlets. The .jsp files are working find but when I try to test a servlet I am getting an error. Can someone please help me with this? I change the web.xml file to enable the servlet and servlet-mapping elements. I also changed the context.xml file and set reloadable to true. I am going to copy in the error that I am receiving.
