hi everyone

I am trting to load an object from my database table MyUserType:

Code:

        Session session = HibernateUtil.openSession();
    MyUserType type=(MyUserType) session.get(MyUserType.class,"1");

but I got this execption:

Code:

org.hibernate.MappingException: Unknown entity: com.ext.portlet.login.model.MyUserType

so I tried with sql query:

Code:

Session session = HibernateUtil.openSession();
MyUserType type=(MyUserType) session.createSQLQuery("select *  from MyUserType where myusertypeid=1;").uniqueResult();

and I got this exception:

Code:

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to com.ext.portlet.login.model.MyUserType

I also tried with hql query

Code:

Session session = HibernateUtil.openSession();
MyUserType type=(MyUserType) session.createQuery("from MyUserType where myusertypeid=1").uniqueResult();

and I've got this new exception:

Code:

org.hibernate.exception.SQLGrammarException: could not execute query

thanks in advance

is MyUserType.class available in same package specified below in your classpath (note that if you are doing in Web application then it should be in WEB-INF/classes or WEB-INF/lib)?
if yes please share mapping file.
