Delegate Servlet cannot access liferay utility beans

[Carlos Alonso Vega, modificado hace 6 años.]

Hi all,

I am trying to build a delegate servlet that needs to know the list of connected users in Liferay (using com.liferay.portal.service.UserLocalServiceUtil)

I had no problem getting a simple delegated servlet to work and say Hello when deployed in Liferay, but when I try to use UserLocalServiceUtil I get this exception

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'com.liferay.portal.service.UserLocalService' is defined

Reading docs it seems that a delegate server could access core portal utilities, but could I be wrong. Any help or advice will be appreciated.

This is the servlet

   

package es.upna.liferay;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.liferay.portal.service.UserLocalServiceUtil;
import com.liferay.portal.service.UserServiceUtil;
import com.liferay.portal.model.User;
import java.util.List;

public class myDelegateServlet extends HttpServlet {

 protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
 
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
 
       try {
 
            out.println("");
            out.println("");
            out.println("");
            out.println("<title>My delegate Servlet</title>");            
            out.println("");
            out.println("");
            out.println("<h1>My delegate Servlet at " + request.getContextPath() + "</h1>");
            
            int userCount = UserLocalServiceUtil.getUsersCount();
            List<user> users = UserLocalServiceUtil.getUsers(0, userCount);
                
            out.print("Connected Users:");
            for (User user : users) 
              {
               out.print("<li>User: "+user.getUserId()+"</li>" );   
              }
            
            out.println("");
            out.println("");
                       
        } 
        catch (Exception e) 
            {
             out.print("Exception! "+e.getMessage() );   
             }          
        finally {
            out.close();
        }
    }
...
</user>
