redirect - How to fix my url in spring framework -

i working spring mvc3.2 , have registration form(http://my-server.com:8080/tracks/apks). users post server , server return error message when validation fails. got error message server, url different wanted. here code:

web.xml <servlet-mapping>     <servlet-name>tracks</servlet-name>     <url-pattern>/</url-pattern> </servlet-mapping>   applicationcontext.xml <bean id="viewresolver"     class="org.springframework.web.servlet.view.internalresourceviewresolver">     <property name="prefix">         <value>/web-inf/pages/</value>     </property>     <property name="suffix">         <value>.jsp</value>     </property> </bean>  @controller @requestmapping("/apks") public class apkcontroller {  @requestmapping() public modelandview index() {     map<string, object> modelmap = new hashmap<string, object>();     modelmap.put("menus",   adminservice.getmenus("apks"));     return new modelandview("apks", "model", modelmap); }  @requestmapping(value = "/insert", method = requestmethod.post) public modelandview uploadapk(apkinfo apkinfo, bindingresult bindingresult) {       map<string, object> modelmap = new hashmap<string, object>();      modelmap.put("menus",   adminservice.getmenus("apks"));       if (!fileexists(apk.getfilename())){       modelmap.put("message", message);       }       //do       return new modelandview("apks", "model", modelmap); } 

after calling uploadapk, expected http://my-server.com:8080/tracks/apks returned url http://my-server.com:8080/tracks/apks/insert.

what do fix it?

thanks in advance.

couple of observation.

1. in web.xml, specify context-paran, servlet tracks , listener?
2. is context:component-scan enabled in spring configuration file?
3. use requestmapping @ method level map request specific method.
