RE: CGI servlet is not found after it gets initialized...
Does anyone know the answer to why this is? Or, perhaps, the prevailing opinion is that I am crazy. It took me a long time to figure out a theory that fit the facts of this problem, and I didn't really believe what I came up with. I don't really know how the internals of Tomcat work and how the CGI servlet attaches to other webapps, but I really can't understand why it works for the CGI servlet (in org.apache) and not for my copy (int dsi.app).
