No mapping found for HTTP request with URI

[rotbart]

Hi! I am newable in SPRING, and have the following question:
I am trying to use MultiActionController for MVC implementation.I decided to delegate the request from the
JSP file to some class I wrote (i.e there is NO inheritance from MultiActionController).

I am getting the error:
No mapping found for HTTP request with URI [/SpringMVC/index.dispatch] in DispatcherServlet with name 'dispatcher'

I added log prints and I see that my requests do not handled by MultiActionController at all!


my web.xml has the next lines:

...
<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>*.dispatch</url-pattern>
    </servlet-mapping>
....

dispatcher-servlet.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="..."
 xmlns:xsi="..."
 xsi:schemaLocation="...">
  <bean id="propsResolver"
   class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
   
   <property name="mappings">
          <value>
           /index.dispatch=goToNextForm
           /*.dispatch=goToNextForm
          </value>
   </property>
  </bean>
  
  <bean id="paramMultiController"
   class="org.springframework.web.servlet.mvc.multiaction.MultiActionController">
   <property name="methodNameResolver" ref="propsResolver"/>
   <property name="delegate">
    <bean class="controller.Form1Controller" />
   </property>
  </bean>
  
 <!-- MULTI CONTROLLER END -->
  
 </beans>

my JSP has the next target on submit:

<form action="index.dispatch">
...
</form>

The question i what do I do wrong????? why the request does not handled by MultiActionController?

[rotbart]

No even single reply... to bad
OK
I would like to ask another question:

What do I need to do to cause all requests to be handled by MultiActionController?
Do I need to change web.xml mapping and to add MultiactionController instead of DispatcherServlet?

Thanks in advance.

I suggest you read the reference guide and take a look at the sample applications. First understand how things work. The DispatcherServlet handles ALL the request but DELEGATES to a controller. In your case your MAC.

There is no Controller named 'goToNextPage' at least not in the snippet you showed here.

Hi

The DispatcherServlet routes the control to the specified controller/handler. The DispatcherServlet looks for the handler-mapping specified in the context. By default it uses BeanNameURLHandlerMapping.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="..."
xmlns:xsi="..."
xsi:schemaLocation="...">
<bean id="propsResolver"
class="org.springframework.web.servlet.mvc.multiac tion.PropertiesMethodNameResolver">

<property name="mappings">
<value>
/index.dispatch=goToNextForm
/*.dispatch=goToNextForm
</value>
</property>
</bean>

<bean name="/index.dispatch"
class="org.springframework.web.servlet.mvc.multiac tion.MultiActionController">
<property name="methodNameResolver" ref="propsResolver"/>
<property name="delegate">
<bean class="controller.Form1Controller" />
</property>
</bean>

<!-- MULTI CONTROLLER END -->

</beans>

Plz note the way i have defined the bean for MultiActionContoller, i have specifed a name instead of an id. Here i am making use of the BeanNameURLHandlerMapping

U can also use SimpleURLHandlerMapping if not BeanNameURLHandlerMapping

U can look into the documentation for indepth understanding.
Let me know if it works

Marten , thanks for your reply!
'goToNextPage' is method name that handles the request.
And yes , I read the rererences, more than once.

Madhusudhan81 , Thanks for your reply!

Yes, it solves the problem: if I add URL path in "name" attribute of the bean, it works.

I found another similar solution. If I add BeanNameURLHandlerMapping and order him to delegate
the requst handling to my MultiActionController bean, it works also:

<bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
		<property name="mappings">
			<props>
				<prop key="/*">paramMultiController</prop>
			</props>
		</property>
	</bean>

As I understand, my problem was that Spring did not forwarded request to MultiActionController bean. It is
strange: I saw examples in Spring docummentation, there are NO additional mappings
(like SimpleUrlHandlerMapping) for request handling, and MultiActionController bean is defined without
"name" attribute! Check by yourself paragraph 13.3.3 of Spring Reference Documentation.

Do I always need to add additional mapping to MultiActionController?

Thanks in advance for answer.

Hi rotbart,

As far as my understanding goes, u always need to have a handler mapping defined in the context. If u dont define any handler mapping, DispatcherServlet creates the default handler mapping for u .

In the spring documentation they have just shown how to configure the
MultiActionController. U need to define the handler mapping if u want the control to be directed to your controller.

Thanks
