"GWT module may need to be (re)compiled" when deployed into the Tomcat and the war is generated with maven

Question

I got the issue( "GWT module 'SmartWPS' may need to be (re)compiled") while accessing the url. I have generated the war file by running maven-clean-install. I placed the same war file in the /webapp folder.

I have developed application using GWT with client side GIN as Dependency Injection and server side as the Spring Dependency Injection. When I am running the maven-clean-install, war file is generating successfully. After placing the war file in the /webapp folder then i am seeing following error in the tomcat logs folder,

My spring-servlet.xml file is like as pasted below,

http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

<!-- The application context definition for the DispatcherServlet -->

<!-- Maps the request through to a concrete controller instance -->
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <value>
        <!-- /**/SampleApp.rpc=sampleAppController -->
        /**/empDetails.rpc=empDetailsController
        </value>
    </property>
</bean>

<!-- GwtRpcController wraps our service in order to decode the incoming -->
<!-- request then delegates processing of the call to the POJO service -->
<!-- and then encodes the return value forwarding the response. -->    <!--<bean id="sampleAppController" class="com.infor.ion.boddesk.server.GwtRpcController">
    <property name="remoteService">
        <bean class="com.infor.ion.boddesk.server.sampleapp.SampleAppService" />
    </property>
</bean>  -->      <bean id="empDetailsController" class="com.infor.ion.boddesk.ui.sample.server.GwtRpcController">
    <property name="remoteService">
        <bean class="com.infor.ion.boddesk.ui.sample.server.EmployeeDetailsServiceImpl"

/>

When enabling with maven iam facing with all these problems, with build.xml, it was just successful and even within jetty server is running successfully.

Thanks, Saritha

Clean the temp files(Run > %temp%) Clean your project(in your IDE) Clean the browsers' cache.(Use CCleaner) Compile the project once again.
