Dispatcher mapping problem

**thebugslayer** · Jul 5th, 2007, 12:12 PM

Hi there,

I wonder if any one has tried successfully mapping "/*" with spring's DispatcherServlet?

Basically I want the following to work:

Code:

<servlet>
		<servlet-name>webapp</servlet-name>
		<servlet-class>
			org.springframework.web.servlet.DispatcherServlet
		</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>webapp</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>

I tried many configuration, and got those handler mapping to controller executed, but the ViewResolver don't seem able to resolve url correctly. I can see log reporting url can't be found that include the contextpath in front. Anyone has issue with this that can give me some pointer?

Thanks,
TBS.

We use it without any problem.

Also if you want an answer including a bit more information (actuall error message, stacktraces, configuration etc.).

mdeinum, Thks for taking interest.

Please note that I am familiar with SpringMVC in general. I have created webapp with urls mapping/setup like these without any problems:

Code:

http://hostname/webappname/springdispathername/<mypath>
http://hostname/webappname/<mypath>.dispatcher

It's just bother me that I can't get mapping style working like following:

Code:

http://hostname/webappname/<mypath>

When I run a webapp (eg: http://localhost:8080/myspringmvc/index) that has this config, I get a HTTP Status 404 page with the following logging:

Code:

So is there configuration that I missed?

take a look at my recent thread: http://forum.springframework.org/showthread.php?t=42820. well, i changed to the mapping "/*" and started having the same problem as you. my controller mapping is:

<bean name="/login.htm" class="myapp.web.LoginController">

using the url http://domain/myapp/login.htm i had these two situations:

1 - using the mapping "<url-pattern>*.htm</url-pattern>" it worked well and i got the spring log:

Code:

...JstlView] - <Rendering view with name 'login' with model {(...)} and static attributes {}>
...view.JstlView] - <Forwarded to resource [WEB-INF/jsp/login.jsp] in InternalResourceView 'login'>
...DispatcherServlet] - <Cleared thread-bound request context: org.apache.catalina.connector.RequestFacade@149f041>
...DispatcherServlet] - <Successfully completed request>

2 - when i changed to "<url-pattern>/*</url-pattern>" it did not work and i got the logs:

Code:

...JstlView] - <Rendering view with name 'login' with model {(...)} and static attributes {}>
...DispatcherServlet] - <Testing handler map [org.springframework.web.servlet.handler.SimpleUrlHandlerMapping@eb9dfa] in DispatcherServlet with name 'myapp'>
...SimpleUrlHandlerMapping] - <Looking up handler for [/WEB-INF/jsp/login.jsp]>
...DispatcherServlet] - <Testing handler map [org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping@2c5f8a] in DispatcherServlet with name 'myapp'>
...BeanNameUrlHandlerMapping] - <Looking up handler for [/WEB-INF/jsp/login.jsp]>
...DispatcherServlet] - <No handler found in getLastModified>
...DispatcherServlet] - <DispatcherServlet with name 'myapp' received request for [/myapp/WEB-INF/jsp/login.jsp]>
...DispatcherServlet] - <Bound request context to thread: org.apache.catalina.core.ApplicationHttpRequest@7af3e0>
...DispatcherServlet] - <Testing handler map [org.springframework.web.servlet.handler.SimpleUrlHandlerMapping@eb9dfa] in DispatcherServlet with name 'myapp'>
...SimpleUrlHandlerMapping] - <Looking up handler for [/WEB-INF/jsp/login.jsp]>
...DispatcherServlet] - <Testing handler map [org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping@2c5f8a] in DispatcherServlet with name 'myapp'>
...BeanNameUrlHandlerMapping] - <Looking up handler for [/WEB-INF/jsp/login.jsp]>
...WARN [org.springframework.web.servlet.PageNotFound] - <No mapping for [/myapp/WEB-INF/jsp/login.jsp] in DispatcherServlet with name 'myapp'>
...DispatcherServlet] - <Cleared thread-bound request context: org.apache.catalina.core.ApplicationHttpRequest@7af3e0>
...DispatcherServlet] - <Successfully completed request>

note that after "Rendering view with name 'login'" it tries to locate a mapping for "myapp" and do not find it. so maybe the problem is that the mappings in myapp-servlet.xml are missing something.

I think the problem might be that it creates some kind of loop, due to the mapping of /*. I checked our configuration and we use a *.htm notation.

Can you create a small sample project that I can use for debugging? I will take a closer look.

**thebugslayer** · Aug 20th, 2007, 03:38 PM

Thanks for give it a shot guys. As I have mentioned earlier, I don't have problem getting it work with a extension mapping. But I am curious as why won't a "/*" mapping won't work.

Attached is a eclipse project that contains files I presented in this post. It's very simple project that depends only on spring and logging and jstl jars.

The project is configured with Maven Eclipse Plugin that auto download all jars and it can be install by this update site: http://m2eclipse.codehaus.org/update

And the project is runable by a Tomcat runtime server inside Eclipse. I am using Tomcat 5.5.

Please do let me know if anyone of you find a solution.

Hum... attachment doesn't seem to work.

See if you guys can download it here

Or email at

Thanks.

Im not so sure you would find /* mapping to be useful; wouldnt that also push all requests for simple static items such as style sheets and images through the servlet as well? Doesnt seem like it is what you are looking for; I bet you would find extension mapping to be your answer (e.g. *.htm, you can even map *.jsp to the spring dispatcher, and it will override the server's implicit mapping for jsp files if you like).
