I am using notepad editor. I am trying to instantiate a DbBean class inside the servlet's init() method.
once i set (C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar) this path to compile the Controller servlet.
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\WEB-INF\classes>set classpath=C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar
C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\WEB-INF\classes>javac Controller.java
Controller.java:5: package bean does not exist

C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\ROOT\WEB-INF\classes>
this is my servlet
import java.sql.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import bean.DbBean;
public class Controller extends HttpServlet
public void init(ServletConfig config)throws ServletException
ServletContext context = config.getServletContext();
context.setAttribute("base_url",config.getInitParameter("base_url"));
{color:#ff0000}DbBean dbbean = new DbBean();{color} {color:#0000ff}error showing in this line
{color}dbbean.setDburl(config.getInitParameter("dburl"));
dbbean.setUserName(config.getInitParameter("username"));
dbbean.setPassward(config.getInitParameter("pwd"));
/// database bean can be access from jsp page
context.setAttribute("dbbean",dbbean);
/// Load the data base driver
try{
Class.forName(config.getInitParameter("jdbcDriver"));
catch(ClassNotFoundException e)
System.out.println(e.toString());
super.init(config);
public void doGet(HttpServletRequest req, HttpServletResponse res)throws ServletException,IOException
doPost(req,res);
public void doPost(HttpServletRequest req, HttpServletResponse res)throws ServletException,IOException
String base = "/onlinetest1/";
String url = base + "login.jsp";
String action = req.getParameter("action");
if(action!=null)
if(action.equals("successlogin.jsp"));
url = base + "successlogin.jsp";
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url);
dispatcher.forward(req,res);
public void destroy()
System.out.println("Servlet stopped");
This below class can be put inside bean folder( (ie)sub dir of controller servlet)
package bean;
import java.sql.*;
import java.util.*;
import java.io.*;
public class DbBean
String dburl="";
String dbuser="";
String dbpass="";
public void setDburl(String url)
dburl = url;
public void setUserName(String uname)
