   static final long serialVersionUID = 1L;
   
    public FindEmpServlet() {
super();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  response.setContentType("text/html");
  PrintWriter out=response.getWriter();
  out.println("<html><body><h2> Emp details </h2>");
  try
  {
   int empno=Integer.parseInt(request.getParameter("EMPNO"));
   // OPEN THE RECORD FOR EMPNO
   Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
   Connection con= DriverManager.getConnection("jdbc  :-o	  dbc:javaoracle","scott","tiger");
   PreparedStatement ps=con.prepareStatement("select empno,ename,job,sal,deptno from emp where empno=?");
   ps.setInt(1,empno);
   ResultSet rs=ps.executeQuery();
   if(rs.next())
   {

Please be sure to use UBB code tags when posting code to the forums. Unformatted code is extermely hard to read and many people that might be able to help you will just move along. Please read this for more information.

You can go back and change your post to add code tags by clicking the .

Pls help

Also, please use real words when posting to the forums. Abbreviations such as "pls" in place of "please" only serve to make your posts more difficult to read and less likely to generate useful responses.

Please read this for more information.

thanks,
