I have been playing around with java web programming a lot lately, and am using the Spring Framework MVC to do this. My problem is that when I go to the url http://localhost:8080/Forum/index.html the spring framework calls the controller it is suppose to call, but when I go to http://localhost:8080/Forum/ it won't call the controller, and I can't seem to figure out how I can get it to do that.

Below is my web.xml file:

EDIT: Nevermind. Sorry.

Maybe you need to play with the mapping options more. All I can think of.

pushkarajthorat · Feb 11th, 2008, 7:05 AM

when you call any URL; procedure to locate this resource within the webserver is:

for a URL:
<http|https>://<hostname|IP>[:portno]/<ApplicationName>/[Resource]
1: Go to the <ApplicationName>'s web.xml
2: Find the matching servlet-mapping tag with <url-pattern> regex. for URL:/[Resource] Go to the servelet-mapping tag.. and execute the servelet-class tag servelet
3: If there is no Servelet-mapping match then resource not found error is displayed.
4: if URL:/[Resource] is blank it will take each <welcome-file> from <welcome-file-list> is taken and used as URL:/[Resource] and execute the whole thing from 2: skipping the 3rd point.

In your second case http://localhost:8080/Forum/ resource is blank and specified welcome-file "index.jsp" is not matching with any servelet-mapping tag's <url-pattern> so... Insted of <url-pattern>*.html</url-pattern> put <url-pattern>*.*</url-pattern> in servelet-mapping tag.. so scope of index.jsp will within the front controller.
