I'm trying to port our applications from 3.2.6 to 4.0.2 using the built-in Hibernate feature of 4.0.2. I followed the directions about building a HAR file but when I start up I get an error that the MySQLDialect can't be found. Has anyone else encountered this error? Since Hibernate is already integrated, should I have to include the Hibernate3.jar in my $JBOSS_DIR/server/app/lib directory? I tried doing that and it didn't work. Any help would be great. My error log is below. Thanks!

Code:

Oi! That's it. Thanks.

One more question, do I need to place mapped Hibernate classes inside the HAR? Or, can the mapped classes be inside a JAR outside the HAR? I only ask because now I'm getting this exception:

I solved my problem by building two separate JARs. The first JAR contains only my Hibernate classes and that's put inside my HAR (had to tweak the MANIFEST file to allow a JAR inside a HAR). The 2nd JAR is my application JAR and that gets deployed outside the HAR.
