Hi all,

I’m using MyEclipse 4.0 GA. Encountered a ClassDefNotFound error with the class antlr/ANTLRException while setting up Hibernate and running it.

According to the Hibernate website, the antlr.jar is required for the Hibernate library set to be put into WEB-INF/lib. However this seems to be missing from my list of Hibernate libraries for 2.1 and 3.0.

Am I having a faulty installation, or could this be a bug?

This was a bug and was corrected either in 4.0 or 4.0.1, sorry for the trouble. You can certainly manually add thsio file to your build path for your project, additioanlly y ou can fix this missing dependency by going to Window > Prefs > MyEclipse > Project Capabilities > Hibernate > 3.0, and adding the JAR there so future use of adding Hibernate capabilities won’t give that same issue.

ok. thanks for the suggestion. I think I’ll just upgrade to 4.0.2 instead. Do I need to re-install it, or can I just update it using Eclipse update? What’s the best way to do so?

Since you are using 4.0 GA you can use the update manager without any problems. We are going to release a 4.0.3 by the end of the week as well that fixes a whole slew of “annoying little bugs” that folks wanted right awawy and didn’t want to wait for 4.1.
