Hi:
I am trying to use hbm2java(hibernate-extensions-2.0.2) with hibernate 2.1. I have a couple of questions :

Is it okay to have differentversions for hibernate and hibernate-extensions ?

When I invoke hbm2java.bat I get the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/collections/MultiMap

I have commons-collections-2.1.jar in my claspath.

any pointers would be greatly appreciated

thanks

The release numbers for the tools don't follow hibernates. Not sure about your class path problem. My guess is that most users are using the Ant task. You could also review the JAOO Tools bundle we created - the tools and hibernate jars are older than current versions but it is setup and may provide a good starting point.

As you can see, hbm2java.bat (below) calls setenv.bat:

[code]
call setenv.bat
java -cp %CP% net.sf.hibernate.tool.hbm2java.CodeGenerator %*
[code]

So, you must have CP environment variable set accordingly.
If your setenv.bat says, for example:

[code]
set CP=...;%CORELIB%\commons-collections.jar;...
[code]

but if %HIBERNATE_HOME%\lib contains commons-collections-2.1.jar, it will not work, since the jars have different names. The same applies to all jars in the %CP%.

Just my 2 cents, maybe it helps.
