Has anyone run into this?

I get a org.hibernate.MappingException: Unknown entity when I try to build the class name like this in a createCriteria but not when I hardcode the class name:

Criteria q = session.createCriteria(className+".class");

I have verified that the class name is building correctly and the string is identical to the hardcoded string.

Any ideas?

Umm. That is because:

"Job.class" != Job.class

The former is a string, the latter is a reference to Job's Class object.

"Job" or Job.class will work, but not what you're doing.

Oh of course! I kept thinking that the the method would pick up the String variable's value but I guess that would mean that there needs to be a method that takes a String in addition to a method that takes a class. doh! I feel so stupid! Thanks!

PS - I think this would be a nice enhancement.

No, to clarify - there is a method that takes a string. Your problem was that the format of the string you were trying to use was wrong. The string you were trying to use was "Job.class" and should have been "Job". Does that make sense?

Yes, thanks!
