UrlFilenameViewController does not return View (Spring-MVC) - spring

According to Spring framework API
UrlFilenameViewController's purpose is:
Transforms the virtual path of a URL into a view name and returns that view
If i request for /info.xhtml, its logical view name is info
See UrlFilenameViewController documentation
Both web.xml and controller is mapped according to
/WEB-INF/web.xml

My smac app deploys fine.
So, if i request for http://127.0.0.1:8080/smac/info.xhtml, Spring-MVC should return /WEB-INF/output/info.jsp. But i have seen in console the following:
No mapping found for HTTP request with URI [/smac/info.xhtml] in DispatcherServlet with name 'controller'
Could anyone help me ?
regards,

You need to configure a HandlerMapping. Default one is BeanNameUrlHandlerMapping which will only do what you want if you bind your controller bean under the name matching your URI. You probably want the SimpleUrlHandlerMapping instead:
<bean name="myController" class="org.springframework.web.servlet.mvc.UrlFilenameViewController"/>
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<value>
/**/*.xhtml=myController
</value>
</property>
</bean>

SimpleUrlHandlerMapping not working for url with few extentions like dsm or ds

I am trying to implement SimpleUrlHandlerMapping in Spring. I am using Spring 4.2.5 version.
Following is my mapping
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
.....
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello1.dsm">hc</prop>
</props>
</property>
</bean>
<bean id="hc" class="com.vaannila.HelloWorldController" >
<property name="message" value="Hello World!" />
</bean>
....
</beans>
When I run tomcat, I get the info message on console saying
org.springframework.web.servlet.handler.AbstractUrlHandlerMapping registerHandler
INFO: Mapped URL path [/hello1.dsm] onto handler 'hc'
But When I hit the url "http://localhost:8080/SpringExample5/hello1.dsm" in my browser I get the requested resource is not available error i.e 404.
Later when I change key to "/hello1.htm", it worked fine with respective url. I am wondering is there any rule on url extention while mapping url to controller.
In web.xml, The dispatcher servlet url pattern is configured to .htm extention
<?xml version="1.0" encoding="UTF-8"?>
............
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>............
and hence It is working fine for ".htm" extention.
To make it work for other extentions we need to set corresponding url-pattern in web.xml file.

Spring MVC: I set the default page but the spring always should me the configuration files do not find

The error you can see in the picture:
HTTP Status 404 - /springupload/WEB-INF/webmvc-config.xml

description The requested resource (/springupload/WEB-INF/webmvc-config.xml) is not available.

I really do not know why I configure the html and jsp page, while it should some configuration file as my start page?
Your configuration is not far from being OK.
One thing I notice is that the hello.html file is in your root WebContent folder. I suppose this is the view you want rendered when you access http://localhost:8080/springupload/ because of this line in the configuration:
<mvc:view-controller path="/" view-name="hello"/>
If this is so, then Spring is trying to resolve to /WEB-INF/hello.html because of the prefix and suffix on this viewResolver :
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="htmlre">
<property name="prefix" value="/WEB-INF/"/>
<property name="suffix" value=".html"/>
</bean>
However, you have two view resolvers with no order in them, and Spring is taking only the first one which resolves to /WEB-INF/hello.jsp, hence the 404 Not found
To wrap it up your solution is to move hello.html to /WEB-INF/ and to change your viewResolver configuration in webmvc-config.xml like so
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="jspre">
<property name="order" value="2" />
<property name="prefix" value="/WEB-INF/"/>
<property name="suffix" value=".jsp"/>
</bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="htmlre">
<property name="order" value="1" />
<property name="prefix" value="/WEB-INF/"/>
<property name="suffix" value=".html"/>
</bean>
Last, you're not supposed to access directly content in the http://localhost:8080/WEB-INF/* URL, so everything you try here will result in a 404 Not found.
change your configuration file name to [dispatcher servlet name]-servlet.xml
http://static.springsource.org/spring/docs/3.0.x/reference/mvc.html

What are the configurations or xml files to run a basic Spring MVC application?

I need to know the basic XML configuration files to put in my Web-inf folder, like web.XML, and where to write view resolver bean.
How do I register the controller?
When I run my application I get the error "could not open servlet context resource". What is servlet context resource and where do I mention it?
My web.xml is:
<?xml version="1.0" encoding="UTF-8"?>

<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
I have these two xml files only.
I know I need a spring configuration file too. I don't know what details I need to put in that.
If you use STS (Spring Tool Suite) then you can create a Spring Template Project.
(New Project/SpringSource Tool Suite/Spring Template Project/-Spring MVC Project)
This contains all the files you need to start.

Java Spring address of page

I am really confused how does the address of my spring application come from.
I followed the tutorial, but now I am trying to change the address, but I can't find the spot.
At the moment address is this : http://localhost:8080/HelloWorld/
Where can I change HelloWorld to something else?
I will provide you with any code you need. I have two conf files : web.xml, spring-servlet.xml, but there is nothing in them that contains HelloWorld.

Actually this is not issue unless you deploy it on production environament.
When you deploy it there you should create new HOST in TOMCAT_HOME/conf/server.xml file
it should look something like:
<Host name="www.mysite.com" appBase="www"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
Second option is to deploy your war file in ROOT directory, but in my opinion the first option is more suitable.
Update: No problem, If you are using eclipse, please click right mouse button on your project, Select Properties - > Web Project Settings.
and change name of your "HelloWorld" directory.
It's the name of your war file.

Tomcat unable to find jsp in war file

I recently switched one of my static html files to a Spring controller that uses a JSP to render its view. I use jetty to test locally and local testing shows the page rendering fine. Upon deploying to our test server, which uses Tomcat 6.0.26, I get the following exception:
javax.servlet.ServletException: Could not get RequestDispatcher for [/WEB-INF/jsp/index.jsp]: check that this file exists within your WAR
org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:219)

The difference between my dev instance and test instance is that the dev instance is deployed to the root (localhost/search.html) whereas the test instance is deployed to server.com/appname/search.html. Appname is the name of the *.war file I deploy. I have tried adding the full path as the prefix to the jps files (/appname/WEB-INF/jsp/) and a number of other combinations with no luck. I have verified that the jsp-api jars are in the tomcat lib directory. My tomcat install is the basic/default install.
The issue was caused by the default jsp servlet being removed from the default web.xml of the tomcat install. This had been done by a former co-worker and not to my knowledge. Replacing the test server's web.xml with the default web.xml (which included url-patterns/servlets for handling jsp files) corrected the issue.
