i tried downloading various Jars. but i am not getting that particular jar which has Synchronization class/interface in any pacakge like transaction.

When i try to import javax.transaction.(Here i couldn't find any Synchronization Class/Interface)

The Synchronization interface is not present under the transaction package

What am i supposed to do now. Where can i get it. help me.

It's not in my Java 6 API; have you tried the J2EE documentation? You might have to install J2EE as well as the standard edition.

I have gone through all suggestions you have told. I am not getting through it. Is there any way to avoid J2EE installation and still get Synchronization interface?

[Rahul Shilpakar]

Is there any other way to get Synchronization interface?

What does the "lib/README.txt in the Hibernate distribution" say?

[Rahul Shilpakar]

I have only jar of hibernate-2.1.3 and when i extract this jar file and i havn't find any lib directory in it.

Where can i read this README.txt file? And what significant point i can achive from it?

[Ilja Preuss]

When you said that you had gone through all the suggestion, I assumed that you also had read the the FAQ entry I linked to, just before that post. There it says:

You are missing a third-party library Hibernate needs, check lib/README.txt in the Hibernate distribution first. You need all classes that are listed as required for runtime.

[Rahul Shilpakar]

I gone through the FAQ of hibernate but havn't find the relative information regarding hibernate distribution.
