Spring MVC - methodNameResolver isn't recognizing the method in the Controller's methods

[Liav Ezer]

Hi,

I wrote a table in jsp using <display:table> tag. I added a pagination support That throws an exception saying:

No request handling method with name 'nextPage' in class [com.liav.adam.admin.spring.controller.AdDetailsCon troller]

This is the table in the jsp

    
<tr >
				<td colspan="3" align="center">
  			 <div style="height: 140px; width:100%; overflow: auto;">
  			   <table width="100%" border="0" cellpadding="0" cellspacing="0" align="center">

             <c:set var="listPageUrl" scope="page">
								<c:url value="/AdDetails.htm"/>
             </c:set>      
                       
		     	   <display:table name="adSummary.inventoryList" 
		     	                  defaultsort="1" 
		     	                  id="inventoryListTable" 
		     	                  style="height: 45px; border:0px solid red; width:100%;"
		     	                  excludedParams="*" 
								            decorator="com.liav.adam.admin.decorator.AdDetailsDecorator"
		     	                  sort="list"
		     	                  requestURI="${listPageUrl}"
		     	                  pagesize="3"
		     	                  >
		     	                  
		     	  <display:setProperty name="paging.banner.first">
						  <span class="pagelinks">
							<input type="image" name="nextPage" src="images/next.jpg">
							<input type="hidden" name="nextPageURI" value="{3}"/>
						  </span>
						</display:setProperty>

						<display:setProperty name="paging.banner.full">
						  <span class="pagelinks">
						    <input type="image" name="prevPage" src="images/prev.jpg">
						    <input type="image" name="nextPage" src="images/next.jpg"> 
						    <input type="hidden" name="prevPageURI" value="{2}"/>
						    <input type="hidden" name="nextPageURI" value="{3}"/>
						  </span>
						</display:setProperty>
						
	   				<display:setProperty name="paging.banner.last">
						  <span class="pagelinks">
							  <input type="image" name="prevPage" src="images/prev.jpg">
							  <input type="hidden" name="prevPageURI" value="{2}"/>
						  </span>
						</display:setProperty>
						
    				<display:column property="name" style="width: 25%" title="Inventory Name" maxLength="15" sortable="false"/>
  					<display:column property="page.site.name" style="width: 25%" maxLength="15" title="Site" sortable="fasle"/>
  					<display:column property="page.name" style="width: 25%" title="Page" sortable="false"/>
        		<display:column property="location.value"  style="width: 25%" title="Placement" sortable="false"/>				          		
					</display:table>
				
			</table>
		  </div>

		</td>		                                            
</tr>

This is the declared bean acting as the controller for the above jsp:

    
<bean id="AdDetailsController" class="com.liav.adam.admin.spring.controller.AdDetailsController" scope="request">
	      <property name="methodNameResolver" ref="adDetailsPageActionResolver"/>
   	   	<property name="adFacade" ref="adFacade"/>
	   	  <property name="adminFacade" ref="adminFacade"/>
  	   	<property name="adSummary" ref="adSummary"/>	
   	   	<property name="sessionForm" value="true" />
   	   	<property name="requireSession" value="true" />
        <property name="commandName" value="adSummary"/>
		    <property name="commandClass" value="com.liav.adam.admin.spring.uiobj.AdSummary"/>
        <property name="formView" value="AdDetails"/>
        <property name="successView" value="AdDetails.htm"/>
	 </bean>
	 
	 <bean id="adDetailsPageActionResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
       <property name="methodParamNames">
         <list>
           <value>prevPage</value>
           <value>nextPage</value>
         </list>
       </property>
   </bean>

And finaly, here is the controller with the problematic methods:

   
public class AdDetailsController extends AbstractSearchListController {
public AdDetailsController() {
		super.setRequireSession(true);
	}
	private AdFacade adFacade;
	private AdminFacade adminFacade;
	private AdSummary adSummary;

@Override
	protected Object formBackingObject(HttpServletRequest request) throws Exception {
...
    return (AdSummary) adSummary;
}

public ModelAndView [b]nextPage [/b](HttpServletRequest request, 
			  					  HttpServletResponse response, 
			  					  InventoryList commandObj,
			  					  BindException errors) {
		
		return super.nextPage(request, response, commandObj, errors);
	} 
	
public ModelAndView [b]prevPage [/b](HttpServletRequest request, 
			  					  HttpServletResponse response, 
			  					  InventoryList commandObj,
			  					  BindException errors) {
		return super.prevPage(request, response, commandObj, errors);
	}

Can you suggest why does the nextPage & prevPage aren't invoked when i press the paging buttons on the screen?

Thanks.
