Hi!
I would like to run a servlet(/FunPacmanServlet) from java.This servlet
would then show a jsp page in web browser. The problem is that the
contents of jsp page is shown in eclipse console, but the browser does
not show the page. Any idea what i'm doing wrong? I am using eclipse
3.2, tomcat 5.5,firefox. Does tomcat maybe need some setting up?
Best regards, Goran
