messagesPresent problem for displaying actionMessage

Hi, all

I feel dizzy to solve this problem in few days. I had searched the forum and tried many solutions but not help.
I hope somebody can help me. Thanks.

The problem is I cannot display the messages in the jsp, it seems that <logic:messagesPresent> always returns false.
I have tried to use the common log to retrieve the saved messages from the request and sure that the message is present.

The web is using jdk1.4.11 + jrun4 + struts 1.2.9 .

Here is the action class:

public class DeviceDetailsPrepareInsertAction extends Action
{
    private static Log log = LogFactory.getLog(DeviceDetailsPrepareInsertAction.class);
 
    public ActionForward execute(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) throws Exception
    {
        DynaActionForm daForm = (DynaActionForm)form;
        
        HttpSession session = request.getSession();
        try
        {
            String custId = daForm.getString("custId");
            
            //Retrieve the customer id from database
            List customer = UserDAO.findUserList();
            request.setAttribute("custlist", customer);                 
                                    
            if ( custId==null || custId.equals(""))
            {
                return mapping.findForward("prepare1");
            } else
            {   
                DeviceInventoryDAO dao = new DeviceInventoryDAO(custId);
                //Search the location of the contact to display as selection
                List locationlist = dao.findLocation(null);
                if (locationlist.size() > 0)
                {
                    session.setAttribute("device.add.custId", custId);
                    session.setAttribute("locationList", dao.findLocation(null));
                    return mapping.findForward("success");
                } else
                {
                    ActionMessages messages = new ActionMessages();
                    messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(
                            "The customer does not define location yet. Please input them before."));
                    saveMessages(request, messages);
                    
                    ActionMessages m = getMessages(request);
                    log.info(m.toString());
                    
                    return mapping.findForward("prepare1");
                }                
            }    
        } catch (Exception e)
        {
            log.info("Exception", e);
            ActionMessages messages = new ActionMessages();
            messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage(
                    "message.exception", e.getMessage()));
            saveMessages(request, messages);
        }        
        
        return mapping.findForward("prepare1");
    }

web.xml

The jsp:

<table width="800px" cellpadding="0" border="0" >
          <tr>
            <td>
              <html:form action="/DeviceDetailsInsertPrepare">

        <logic:messagesPresent>

            </html:messages>
          </td>
        </tr>
        </logic:messagesPresent>
 
                  <tr>
                    <td><bean:message key="inventory.device.details.custId"/></td>
                    <td><html:select property="custId"><html  :-o	  ptions collection="custlist" property="custId" /></html:select></td>
                  </tr>
                  <tr>
                    <td> </td>
                    <td><html:submit /></td>
                  </tr>
              </table>
              </html:form>
            </td>
            <td width="8px"></td>
          </tr>
        </table>

The problem is the way you're constructing messages. The String parameter that the ActionMessage constructor accepts is not for the message itself, but for a message key which is to be found in the ApplicationResources.properties file.

In your example, you should make the following entry in ApplicationResources.properties:

error.undefined.location=The customer does not define location yet. Please input them before.

Then in your action class, code this;

messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("error.undefined.location"));

Seethis link for more information on how to set up and configure your message resources.

It works now.

Thanks, Merrill.
