Hello everbody,

I have a problem in inserting data in database using hibernate,
Lets i explain total scenario of my problem,

I creates three tables in mysql database.

1) Category:
which has following fields.

-cid (int 6)(primary key,)
-cname (varchar 100) (NULL)
-description (varchar 100) (NULL)
-parentid (int 6) (NULL)

2)Test:
which has following fields.

-tid (int 6) (primary key,)
-tname (varchar 100) (NULL)
-criteria (varchar 100) (NULL)
-cid (int 6) (references Category(cid)) (NULL)

3)Question:
which has following fields.

-id (int 6) (primary key,)
-qid (int 6) (NULL)
-question (varchar 100) (NULL)
-option (varchar 100)
-answer (int 1)
-tid (int 6) (references Test(tid)) (NULL)
-cid (int 6) (references Category(cid))


I am using NetBeans 6.8 IDE and tomacat server.
I ceates java web application with hibernate.
first i creates reverse engineering and then creates "Hibernate mapping files and POJOs from database"

please make one java package named as "pojos" and creates all pojos and hbm files in that package.


below is all pojo and hbm files..........

1)category.hbm.xml :-

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

}

----------------------------------------------------------------------------------------

now I created one package named as "servlets" and make one servlet as "addQuestionData".

below is that servlet "addQuestionData.java" :-


package servlets;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import pojos.Category;
import pojos.Question;
import pojos.Test;

public class addQuestion extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {

SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session s = sf.openSession();
Transaction tx = s.beginTransaction();

Category c = new Category();
c.setCname("gate-2011");
c.setDescription("Entrence for MTech.");
c.setParentid(0);

s.save(c);
tx.commit();

out.print("Category Data saved.<br/>");

Test t = new Test();
t.setTname("Test1");
t.setCriteria("20:2:1;");
t.setCategory(c);

tx.begin();
s.save(t);
tx.commit();

out.print("Test Data saved.<br/>");

Question q = new Question();
q.setQid(1);
q.setQuestion("name");
q.setOption("jayesh:pratik:priyanka:pruthika;");
q.setAnswer(1);
q.setTest(t);
q.setCategory(c);

tx.begin();
s.save(q);
tx.commit();
s.close();
out.print("Question Data saved.");

}catch(Exception ex){
ex.printStackTrace();
}
finally {
out.close();
}
}

// <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
/**
* Handles the HTTP <code>GET</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}

/**
* Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}

/**
* Returns a short description of the servlet.
* @return a String containing servlet description
*/
@Override
public String getServletInfo() {
return "Short description";
}// </editor-fold>
}

----------------------------------------------------------------------------------------

After run the servlet , it will insert data in category and test table,
but it will not insert data in to question table,
i got this error :-
