Hello forum i have used a week now trying to make the http://www.myeclipseide.com/images/tutorials/quickstarts/struts/ to work without any luck, is there any other tutorial specificly for my eclipse
because i want to take advantage of the integreated servers, so Wouldn’t
have to make my own build.xml.
I have made an example by following http://www.myeclipseide.com/images/tutorials/quickstarts/struts/
how do i called a struts application packed in war ?
************************************************************
when i do http://localhost:8400/TEST/Login.jsp
I get the following error

HTTP Status 500 –

Edit your struts-config.xml file, and change your “path” attribute from “login” to “/login”
