Springs dispatcher servet searching a jsp page instead of calling a controller method -

hi trying authenticate user seems calling jsp page instead of controller mapping.

my dispatcher servlet is

<bean id="datasource"     class="org.springframework.jdbc.datasource.drivermanagerdatasource">     <property name="driverclassname" value="${database.driver}" />     <property name="url" value="${database.url}" />     <property name="username" value="${database.user}" />     <property name="password" value="${database.password}" /> </bean>  <bean id="sessionfactory"     class="org.springframework.orm.hibernate3.annotation.annotationsessionfactorybean">     <property name="datasource" ref="datasource" />     <property name="annotatedclasses">         <list>             <value>com.beingjavaguys.domain.user</value>             <value>com.beingjavaguys.domain.chat</value>         </list>     </property>     <property name="hibernateproperties">         <props>             <prop key="hibernate.dialect">${hibernate.dialect}</prop>             <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>         </props>     </property> </bean>    <bean id="hibernatetransactionmanager"     class="org.springframework.orm.hibernate3.hibernatetransactionmanager">     <property name="sessionfactory" ref="sessionfactory" /> </bean> 

my web.xml is

dispatcher org.springframework.web.servlet.dispatcherservlet 1

<servlet-mapping>     <servlet-name>dispatcher</servlet-name>     <url-pattern>*.html</url-pattern> </servlet-mapping>  <welcome-file-list>     <welcome-file>index.jsp</welcome-file> </welcome-file-list> 

and controller is

@requestmapping(value="/authenticate",method=requestmethod.post)     public modelandview getauthenticateresult(@modelattribute("user") user user,             bindingresult result) {         if(userservice.authenticate(user))         {             return new modelandview("/userlist");         }         else{         return new modelandview("login");         }     }  @requestmapping(value="/userlist", method=requestmethod.get)     public modelandview getuserlist() {         map<string, object> model = new hashmap<string, object>();         model.put("chat", userservice.getchat());         return new modelandview("userdetails", model);      } 

i calling authenticate.html login file using post method problem error

http status 404 - /spring-hibernate-integration-helloworld/web-inf/view/userlist.jsp  type status report  message /spring-hibernate-integration-helloworld/web-inf/view/userlist.html.jsp  description requested resource not available. 

why searching jsp file instead of redirecting controller method? if use redirect:/userlist.html works then.whats logic behind it?

if return string interpreted name of view render. name of view passed no viewresolver (in case internalresourceviewresolver) generate (internal) url forward to. in case jsp.

now redirect: , forward: prefixes 2 special cases. redirect: result in client side redirect url, in turn call controller due configuration. forward: handled on server side , not client side.
