Difference between / and /* in servlet mapping url pattern
(5 answers)
Closed 8 years ago.
What is the difference between:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
And:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
?
/ matches only root ie. http://yourserver/webapplication/. /* matches all requests hitting your application http://yourserver/webapplication/ as well as http://yourserver/webapplication/any/path/you/want
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
maps http://server.local/your-application/ to dispatcher servlet
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
maps http://server.local/your-application/%ANYTHING% to dispatcher servlet

I'm having trouble with the servlet mapping in web.xml. It works when I put in a specific file but not when using a wildcard:
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/resources123/bootstrap.css</url-pattern>
</servlet-mapping>
This works fine. But when I change the URL pattern to /resources123/* it doesn't hit the DispatcherServlet.
I am developing one Spring Web application with Intellij IDEA deployed to tomcat.
I met the issues below:
When I set the application context to the application name(my app) in the Run/Debug configuration page then run tomcat i can access the tomcat homepage and can see "myapp" in the manager page but can't access it.
The URL will be "localhost:8080/request" when clicking myapp in the manager page.
I have to add "myapp" to the URL as "localhost:8080/myapp/request".In this way the requested page can be accessed.
But if i removed "/myapp" from application context leaving it blank in the Run/Debug configuration page then run tomcat i will access the requested page successfully.
The URL is "localhost:8080/request" now the same as before without "myapp".
If I just added the myapp.war file in /webapps folder the result is the same as the first scenario.
What i want is that I put the war file in /webapps folder and start the tomcat server then the page can be accessed.
Anything wrong i have done for the configuration or missed something?
Thanks in advance for the help.

Here is my web.xml:

<init-param>
<param-name>contextConfigLocation</param-name>

</servlet>
<servlet-mapping>
<servlet-name>springServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
but, when I try it out in Swagger-ui, it sends a request having a url without suffix '.do', surely 404 returns, how can I config it?
One way to fix it is to do some changes in the js of Swagger-ui, but it's not a good way.
I have a webapp that works with Tomcat 8 and Jetty 8. Recently, we have introduced servlet-mappings
<servlet>
<servlet-name>page</servlet-name>
<jsp-file>/Dashboard.html</jsp-file>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>page</servlet-name>
<url-pattern>/editjob</url-pattern>
</servlet-mapping>
When you put an url with "http://localhost:8080/app/editjob", in tomcat is redirected to "http://localhost:8080/app/Dashboard.html". But when we deploy it using embed Jetty, a 404 Not Found it is being returned. It seems that the servlet-mapping is not working.
HTTP ERROR 404
Problem accessing /app/page. Reason:
Not Found
Powered by Jetty://
I can enter in the app by using directly
http://localhost:8080/app/Dashboard.html. Without mappings, we have no problem with jetty
This is the code for embedding Jetty:
final Server server = new Server();
SocketConnector connector = new SocketConnector();
connector.setMaxIdleTime(-1);
connector.setSoLingerTime(-1);
connector.setPort(8080);
server.setConnectors(new Connector[]{connector});
final WebAppContext context = new WebAppContext();
context.setServer(server);
context.setContextPath("app");
context.setWar(location.toExternalForm());
server.setHandler(context);
context.start();
server.join();
This is the web.xml with the mappings.

I have tried to define the servlet-mappings when i start the server, but did not work.
This mappings are working perfectly with Tomcat, but Jetty...I dont know which could be the problem.
Thanks in advance.
Problem accessing /app/page.
That URL is not mapped anywhere in your pasted web.xml
The servlets with urls patterns (defined in <servlet-mapping> entries) are:
/webresources/*
/login
/home
/jobs
None of those will match on a request URL of /page, resulting in the DefaultServlet (which is default mapped at /) returning a 404 for that requested resource.
Also, you haven't setup JSP in your embedded-jetty environment, so no JSP is being used.
Copied from prior answer https://stackoverflow.com/a/28483349/775715
If that code snippet represents how you are initializing your webapp, then you are missing a lot of JSP initialization steps.
There's an example project produced by the Jetty Project showing how to use JSP with embedded Jetty at
https://github.com/jetty-project/embedded-jetty-jsp
Pay attention to ...
The dependencies you need
The required ClassLoader type
The scratchDir declaration
The ServletContainerInitializer setup
The Jsp Servlet Holder and mappings
The InstanceManager
(just to name a few big ones)
The project(named:'myproject') use Spring MVC framework. The default page will be "index.action", web.xml configed as below:
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.action</welcome-file>
</welcome-file-list>
The server response 404 not found When while visiting http://www.example.com/myproject/, but it works fine while visiting http://www.example.com/myproject/index.action.
Any help will be appreciated!
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Changing the servlet mapping to the above means all request mappings will handled by spring.
