Оригинальный портлет выглядит следующим образом:

package org.jboss.portlet.hello;

 

import javax.portlet.GenericPortlet;

import javax.portlet.PortletException;

import javax.portlet.RenderRequest;

import javax.portlet.RenderResponse;

import javax.portlet.UnavailableException;

import java.io.IOException;

import java.io.PrintWriter;

 

public class HelloWorldPortlet extends GenericPortlet

{

   protected void doView(RenderRequest rRequest, RenderResponse rResponse) throws PortletException,

IOException, UnavailableException

   {

      rResponse.setContentType("text/html");

      PrintWriter writer = rResponse.getWriter();

      writer.write("Hello World!");

      writer.close();

   }

}

Модифицированный портлет:

1 package org.jboss.portlet.samplesql;

 

2 import javax.portlet.GenericPortlet;

3 import javax.portlet.PortletException;

4 import javax.portlet.RenderRequest;

5 import javax.portlet.RenderResponse;

6 import javax.portlet.UnavailableException;

7 import java.io.IOException;

8 import java.io.PrintWriter;

 

9 import java.sql.*;

10 import java.util.Properties;

 

 

11 public class SampleSQLPortlet extends GenericPortlet

12 {

 

13 Connection conn = null;

14 String url = "jdbc:mysql://localhost:3306/";

15 String userName = "jbossuser";

16 String password = "";

 

17   public void init()

18   {

19   }
