could not instantiate ClassValidator

I have a problem with using Hibernate Tools and Classes with Validator Annotations.

When I compile and run my program I don't have any errors, however, when I try to open a Session in HibernateTools the following Exception is thrown...

I haven't modified the validator bundle resource files. I tried putting hibernate-annotations...jar in the Tool's class-path but nothing worked.

Thank you in advance

Hibernate version:
Hibernate 3.2, Hibernate Tools 3.2.0 beta9 & Nightly of 1 Feb 2007

don't put any hibernate jars into the custom classpath...does not work out well ;)

If you could reduce this to the simplest project for which it fails then attach it to a new jira case and i'll look at it to see if there is something weird going on.

Thank you max, for your reply...

I got it working now, however.

I used @NotEmpty on a String Property:

Code:

class Test {
  @Id
  @GeneratedValue
  long id;

  @NotEmpty
  String test;

  ...  getters/setter/equals/hashCode

}

Now I replaced @NotEmpty with @NotNull and the session is created w/o problems... However, I don't think, this Exception should be thrown, as in the documentation @NotEmpty is available for any type of property.

Should I still file a JIRA case?

Greetings

yes please so i can ensure we don't have a classpath/loader issue internally.

Filed it in JIRA:

Any chance that this issue is going to get resolved?

I can't use the Hibernate3 Maven Plugin until this is resolved. (See http://jira.codehaus.org/browse/MOJO-817)

you are mixing up hibernate.jar versions, at least using an old version of validator
