Comment afficher le message de réussite dans liferay sans utiliser de session?

Question

Ceci est ma première question sur ce site. S'il vous plaît ignorer mon erreur grammaticale anglaise.

J'essaye d'afficher le succès et le message d'erreur dans liferay sans utiliser la session après avoir soumis la réponse dans la page.

J'utilise liferay6.2CE

Mon contrôleur est ci-dessous.

Comment faire?

Toute aide ..

Answer 1

Je l'ai

Dans méthode processAction i utilisé ci-dessous le code.

Boolean bl=s.getoutputList(outputList,userId); 

     if(!bl){ 
      actionResponse.setRenderParameter("Result", TestDetailsConstants.TEST_ERROR_MSG); 
     } 
     else{ 
      actionResponse.setRenderParameter("Result",TestDetailsConstants.TEST_SUCCESS_MSG); 
     } 

J'appelle cela dans méthode doView et passer msg à jsp et l'affichage

public void doView(RenderRequest renderRequest, RenderResponse renderResponse) throws IOException, PortletException 
    { 
     String viewPage=""; 
     String s=""; 
     try 
     { 

     viewPage = "/view.jsp"; 
     s=renderRequest.getParameter("Result"); 

     renderRequest.setAttribute("Strimgmesg",s); 
     }// try block ends here 
     catch (Exception e) 
     { 
      e.printStackTrace(); 
     }// catch block ends here 

     finally { 

      include(viewPage,renderRequest,renderResponse); 
     } 
    } 

Dans JSP

</br> <input type="submit" id="submit" value="Submit"> 
     <% 
      String a = (String) renderRequest.getAttribute("Strimgmesg"); 
     %> 
     <% 
      if (a != null) { 
     %> 
     <%=a%> 
     <% 
      } 
     %>
