oh ! I posted mapping file again instead of pojo ..
Course pojo ::

import java.io.Serializable;

public class Course implements Serializable
{
    private long courseID;
	
	private String courseName;
	private Integer creditPoints;
  
	public void setCourseName(String courseName) {
		this.courseName = courseName;
	}
	public String getCourseName() {
		return courseName;
	}
	public void setCreditPoints(Integer creditPoints) {
		this.creditPoints = creditPoints;
	}
	public Integer getCreditPoints() {
		return creditPoints;
	}
	public void setCourseID(long courseID) {
		this.courseID = courseID;
	}
	public long getCourseID() {
		return courseID;
	}
		
	   
}

[Waswani Naresh]

Please provide RegisterStudent POJO and the code for inserting the object as well.

Could you also provide complete stack trace.

Interesting thing is that for the courseID field you have specified access="field" in your mapping file, still Hibernate is trying to use getter.
