Hi,
I am using Hibernate3.2 with MySql Server 5.0.

I have written the following Servlet code

Code:

[color=darkred]import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

import org.hibernate.*;
import org.hibernate.cfg.*;
import org.hibernate.SessionFactory.*;

import employee.Department;

public class departmentTest extends HttpServlet {

    private SessionFactory sessionFactory;
    
    public void init(ServletConfig config) throws ServletException
    {

   super.init(config);
   try{
      sessionFactory = new Configuration().addClass(Department.class).buildSessionFactory();
      

   }catch(Exception e)
   {
      e.printStackTrace();
   }   


    }

    private void displayAll(PrintWriter out, Session session)
    {
   try {
   
      out.println("<html>");
      out.println("<table border = '1'>");
      out.println("<tr><th>Department ID</th><th>Name</th></tr>");

      List depts = session.find("from departments");
   
      Iterator iter =  depts.iterator();
      while(iter.hasNext())
      {

         Department dept = (Department)iter.next();         
         out.println("<tr><td>");
         out.println(dept.getId());
         out.println("</td><td>");
         out.println(dept.getName());
         out.println("</td><tr>");

      }
   }catch(Exception e)
   {
      e.printStackTrace();
   }
    }         
        
    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
    {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        
   Session session=null;
   
   try{
      session=sessionFactory.openSession();
      
      String action = request.getParameter("submit");
      if(action.equals("Get Departments"))
      {
         displayAll(out, session);
   
      }
      else
         out.println("Bad Input");
   
      session.flush();
      session.close();      

   }catch(Exception e)
   {
      e.printStackTrace();
   }
    }



public void doPost(HttpServletRequest request, HttpServletResponse response) 
throws IOException, ServletException
{
   doGet(request,response)   ;
}
}[/color]
