Hibernate version:3.0

I am using HibernateUtil written by chritianbauer for getting the session and Transaction I am Getting the error that session is closed
while excuting the following code.

public static String create(ICategory category)throws CategoryNotFoundException
{
if(category==null)
{
throw new CategoryNotFoundException("category Not Found");
}
String msg = "Category created";

category.setId(UniqueIdGenerator.getUniqueId());




try{
HibernateUtil.beginTransaction();
HibernateUtil.getSession().save(category);
HibernateUtil.commitTransaction();
HibernateUtil.closeSession();
} catch(HibernateException ex)
{
System.out.println("Class CategoryManager Function: createCategory");
ex.printStackTrace();
msg= "category All ready Exists";

}

setRefreshed(true);






return msg;
} // end create

With 3.0, you no longer need to do this. Read [/quote]

Tomcat is not a managed environment, so he still needs HibernateUtil. Since he doesn't show it we don't know what could be wrong in his implementation of it. He also doesn't care about "BEFORE POSTING" steps: http://www.hibernate.org/ForumMailingli ... AskForHelp
