Does the table 'COURSES' definetly exist in your database?

Zolf

ASKER

no i was expecting hibernate to create that for me

Gurvinder Pal Singh

looks like you dont have the COURSES mapped. Do you have something like
Course.hbm.xml?

or you haven't added

<mapping resource="com/zolf/Course.hbm.xml"/>

to hibernate.cfg.xml?

can you show the query also?

you need to use com.zolf.Course in the query in place of COURSES

Zolf

ASKER

can you please tell me more specific,since i am new to hibernate

Zolf

ASKER

here is the main code

package com.zolf;

import java.util.Calendar;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;

import com.util.HibernateUtil;

public class Main
{
	public static void main(String[] args)
	{
		Calendar c = Calendar.getInstance();
		c.set(2011, 03, 31);
		Main m = new Main();
		Long courseId1 = m.saveRecord("Hibernate", "ABCD", c, 1);
	}

	public Long saveRecord(String courseName, String courseFaculty,
			Calendar courseDate, int courseDuration)
	{
		Long recordID = null;

		Session session = HibernateUtil.getSessionFactory().openSession();
		Transaction transaction = null;

		try
		{
			transaction = session.beginTransaction();
			Course course = new Course();
			course.setCourseName(courseName);
			course.setCourseFaculty(courseFaculty);
			course.setCourseDuration(courseDuration);
			course.setCourseDate(courseDate);
			recordID = (Long) session.save(course);
			transaction.commit();
		} catch (HibernateException e)
		{
			// TODO Auto-generated catch block
			transaction.rollback();
			e.printStackTrace();
		} finally
		{
			session.close();
		}

		return recordID;

i checked the db and the table has been created and the value has been inserted into the table.
one thing when i set the date to 31/3/2011 in my code,but in the table it is something else.why??

Sathish David Kumar N

check the data inserted today ?

Zolf

ASKER

what do you mean

colr__

Sorry, just back from lunch! Is it a java.util.Date object in your code, or a String? And what is the type of the column in the database?

colr__

Also, what is the value that ends up in the database?

Zolf

ASKER

>>Is it a java.util.Date object in your code,
please see my code i pasted above.

>>And what is the type of the column in the database?
datetime.the table was created by hibernate,after adding the tag you mentioned in the cfg.xml file

also i get some message in my eclipse console which i paseted above.can you please tell me the reason for it

colr__

I'm not sure, but I suspect its something to do with using a Calendar - try using a Date instead

Zolf

ASKER

i get error if i change the Calender to Date
