Hello,
New to Hibernate and Open Source projects and I'm fiding this very interesting! Great job to all! I wanted to reverse engineer my hbm files to see if I had designed my class properly but I'm having a heck of a time getting code generator to run. It will be a very simple question for most of you but I don't have much experience running from the command prompt.

The instructions advise java -cp [hibernate_classpaths] net.sf.hibernate.tool.hbm2java.CodeGenerator [options] [mapping_files].

My (dumb) question is basically could someone give a real world example exactly what would go in those optional boxes. secondly, what position on the drive to you navigate to with command prompt before this would be run. I can't quite figure which Jar files will be necc. to run, also do I need to put anything in the environmental variables? It seems I need multiple jar files from multiple places. Also what is the format for the last variable, the mapping files, i.e. is it the whole path? Or should that file sit in the output directory?

Thanks in advance!

Jim

I was right where you are, on Monday. Here is the bat file that I came up with, and just ran it (doesn't matter from where):
--------------------------------------------------------------------
set JDBC_DRIVER=%ORACLE_HOME%\jdbc\lib\classes12.zip
set HIBERNATE_HOME=c:\test\hibernate-2.0.3

set CORELIB=%HIBERNATE_HOME%\lib
set LIB=..\lib
set PROPS=%HIBERNATE_HOME%\src
set CP=%JDBC_DRIVER%;%PROPS%;%HIBERNATE_HOME%\hibernate2.jar;%CORELIB%\commons-logging.jar;%CORELIB%\commons-collections.jar;%CORELIB%\commons-lang.jar;%CORELIB%\cglib.jar;%CORELIB%\dom4j.jar;%CORELIB%\odmg.jar;%CORELIB%\xml-apis.jar;%CORELIB%\xerces.jar;%CORELIB%\xalan.jar;%LIB%\jdom.jar;%LIB%\..\hibernate-tools.jar

java -cp %CP% net.sf.hibernate.tool.hbm2java.CodeGenerator -output=C:\test\java\ C:\test\*.xml
