SERVICE BUILDER USING MULTIPLE TABLES

SERVICE BUILDER USING MULTIPLE TABLES

This is the UserAFinderImpl class in this class I have declared 1 method. i.e findUser() this method takes no argument and gives the result in the form of list object.

package com.adrsuser.slayer.service.persistence;

import java.util.ArrayList;

import java.util.List;

import javax.portlet.ActionRequest;

import com.adrsuser.slayer.model.AddressU;

import com.adrsuser.slayer.model.UserA;

import com.adrsuser.slayer.model.impl.AddressUImpl;

import com.adrsuser.slayer.model.impl.UserAImpl;

import com.liferay.portal.kernel.dao.orm.SQLQuery;

import com.liferay.portal.kernel.dao.orm.Session;

import com.liferay.portal.kernel.exception.SystemException;

import com.liferay.portal.service.persistence.impl.BasePersistenceImpl;

import com.liferay.util.dao.orm.CustomSQLUtil;

public class UserAFinderImpl extends BasePersistenceImpl implementsUserAFinder{

      public static String FIND_USERS = "findUsers";

     

      public List findUser() throws SystemException

      {

            Session session = null;

            try

            {

                 

            List objectListUserAddress=new ArrayList();

             List objectListUser=new ArrayList();

              List objectList=new ArrayList();

            

 session = openSession();   

                   String sql = CustomSQLUtil.get(FIND_USERS);

                   

                   System.out.println("Query   -----"+sql);

                   

                   SQLQuery query = session.createSQLQuery(sql);

                   

                   query.addEntity("UserA", UserAImpl.class);

                

 objectListUser=(List)query.list();

            

 objectList.add(objectListUser);

           

                    session=openSession();

                  query = session.createSQLQuery(sql);

                  query.addEntity("AddressU", AddressUImpl.class);

                  objectListUserAddress=(List)query.list();

                  objectList.add(objectListUserAddress);

                    

                  return (List)objectList;

                 

            }

            catch (Exception e) {

                  System.out.println(e);

                 

            }

            return null;

      }

     

      }

In My jsp page I have written simply like this…

<%@page import="java.util.ArrayList"%>

<%@page import="com.adrsuser.slayer.model.UserA"%>

<%@page import="com.adrsuser.slayer.model.AddressU"%>

<%@page import="java.util.List"%>

<%@page import="com.adrsuser.slayer.service.UserALocalServiceUtil"%>

<h1>success fully reached....</h1>

<%

List objectListUser=new ArrayList();

List objectList=new ArrayList();

objectList=UserALocalServiceUtil.findUser();

List<UserA> h1=(List)objectList.get(0);

List<AddressU> h2=(List)objectList.get(1);

        for(UserA ha:h1)

          {

          %>

<%=ha.getUaid() %>

 <%=ha.getUid()%>

<%=ha.getUname()%>

         <% }

      

          for(AddressU hb:h2)

          {

       %>

       <%=hb.getCity()%>

       <%=hb.getState()%>

       <%=hb.getCountry()%>

       <%

       }

       %>

This is my service.xml here are 2 tables UserA and AddressU.
