Hi, it's jta.jar which comes with Hibernate.
In Eclipse, make an additional project containing all jars you have. So you can always search for any class using Ctrl-Shift-T finding the right jar for it an add it to the project. Even better: You can also make a function less class in your project like follows: import javax.transaction.Synchronization; public class Imports { Synchronization a; } For the application without any funktion, just to document all the ClassNotFoundExceptions you faced. If you get another ClassNotFound, just add the not-found-class to your "Imports" class. There will be two errors displayed in Eclipse. Go to the (erroneous) import statement, Press Ctrl-1 and select "Add jar to project build path". A very simple way to document which jars are needed and to get them into the project.
