II upgraded today to the latest versions of hibernate & annotations. This code worked with 3.1beta3 but now it complains about a missing @Enitity annotation that is already there. Any ideas. Is it because I have rc2 ?

Name and version of the database you are using:

The generated SQL (show_sql=true):

Debug level Hibernate log excerpt:

This should work, are you sure, you're using @javax.persistence.Entity and not the org.hibernate.annotations one?

As you can see from the imports, it's javax...Entity. I don't know what the heck is wrong with this, as I told you it worked before

You'll need to play with the debugger, I don't know what's going on

I had a working application that spontaneously started complaining about missing entity tags. Does anyone have an idea of what steps I should take to troubleshoot this issue?

Here's the error:
org.hibernate.AnnotationException: Annotated class should have an @Entity annotation: RemediationType

Here's what I remember:

The application was working fine yesterday. It's been working for 2 months now. I made some minor changes which all seemed to work fine. I restarted the server and everything worked fine. I shut down the server (my workstation) and start it up today and I get this error. I used to map 10 classes in my configuration file and whatever was the first annotated class would appear in the error message (so I'm certain it's nothing to do with my actual class). I suspect it's classloader or hibernate configuration related, but am stumped.

I'd appreciate any help possible with this issue.

Thanks,
Steven

Here's the class:



Here's my config:

It appears my issue was Tomcat/WTP and not hibernate. Eclipse WTP 0.7 failed to synchronize my classes and libraries properly after a major change. I fixed the issue by recreating my eclipse project.

Thanks all!
