Hello, And I am also cannot login the admin page of the tomcat. What is the username and password for the tomcat admin page? There is a file named tomcat-users.xml in yout /conf directory (in tomcat_home). Just add a user with a fairly complex password with the role admin. Also change the defuault password tomcat for the other users, just in case... I'm new with Tomcat, but it work for me! Gustavo Comba

So I don't know is that any error on the line that I add to the web.xml. Since the applcation is running on the Jrun with no problem and I only change the environment from Jrun to tomcat. And tomcat and Jrun seems to be the same to be the servlet engine. So I think there is the problem of the setting. But I still do not where is the problem come from.
