Hi all,

I am trying out Hibernate after longtime. Facing issues right away. I was following some example on the net.

There are three tables: students, courses and student_courses.

Hibernate mappings:
1. Course.hbm.xml

2. Student.hbm.xml

Then I have the two POJO classes for Course and Student.

I am trying to execute this code:

Right away I get the error:

I have declared courseId as int in the POJO and in the mapping as you see.

Can you explain why this error happens still?

I agree. Here's the link:
