[jboss-user] [JBoss/Spring Integration] - Problem persisting data using Spring + Hibernate JPA

[suneetshah]

Hello,

I am getting the following exception when I try to insert a record into mysql. I am using Spring 2.03 with Hibernate JPA. I have pasted my code below and the config files.

Any help would be greatly appreciated.

public class ServiceMgr {

protected ServiceDAO serviceDao;
	
public ServiceMgr() { 	}
	
public ServiceMgr(ServiceDAO serviceDao) {
	super();
	this.serviceDao = serviceDao;
}
	

public Service getService(String id) {
		return serviceDao.findById(id);
