Spring Framework Controller
 
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:
:
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  3.   <display-name>Forum</display-name>
  4.  
  5.   <servlet>
  6.           <servlet-name>springapp</servlet-name>
  7.           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  8.           <load-on-startup>1</load-on-startup>
  9.   </servlet>
  10.  
  11.   <servlet-mapping>
  12.           <servlet-name>springapp</servlet-name>
  13.           <url-pattern>*.html</url-pattern>
  14.   </servlet-mapping>
  15.  
  16.   <welcome-file-list>
  17.     <welcome-file>index.jsp</welcome-file>
  18.   </welcome-file-list>
  19.  
  20. </web-app>

Below is my springapp-servlet.xml
:
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

Re: Spring Framework Controller
 
EDIT: Nevermind. Sorry.

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

Re: Spring Framework Controller
 
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.
