Hibernate version:3.1 beta3 + tool 3.1 alpha 5
try to reverse engineering from db, build error:

java.lang.NoClassDefFoundError: org/hibernate/cfg/HbmBinder$SecondPass

Checked the hibernate3.jar(3.1 beta3), it does not have HbmBinder$SecondPass.class, downloaded hibernate3.0.5.jar which has the class, and put into classpath, the issue is gone. However I have 2 hibernate3.jar now. Is this a bug in either tool or core? Thanks.

that is because alpha5 uses 3.1 b2 not b3.

just use the hibernate.jar that comes with the tools to do rev.eng etc.
