I am newbie and trying to integrate glassfish with hibernate.

I am getting the following error msg when server starts

Please help.

I'm sad to say, it's as simple as that jar not being available to your applications when they are deployed.

Identify which application is throwing that exception, and then find out where the jar file containing that class comes from. Make sure it's either packaged with the app, or placed on the classpath of the server, although depending on how classloaders are configured, that might not be the silver bullet.

In all likelihood, the developers linked to the jar file externally during development, so it wasn't part of the deployed application, and now you're having a ClassNotFoundException on the server.

Hope that helps!

Thanks for the reply Cameron, but can you let me know the jar name that I need to include..I have googled this error and sometimes some one says you need to remove hibernate3.jar, sometimes remove the annotations jar. Nothing has worked so far.

Currently, I have I have hibernate3.jar, hibernate-annotations.jar and hibernate-common-annotations.jar in lib directory of glassfish.

Yes, its correct. Glassfish looks at those hibernate files at run time in its lib directory and that's where it throws this error on server startup.

Tom.

Never mind.

I added hibernate-validator.jar to lib and its working fine (although I am getting other exceptions like java.lang.reflect.InvocationTargetException
but the validator exception is gone.

Thanks for the reply and bearing with a newbie in Hibernate.
