In Hibernate 3.0 Beta 4, SchemaExport.bat has some older libs in the class path:

Old CP Setting
set CP=%JDBC_DRIVER%;%PROPS%;%HIBERNATE_HOME%\hibernate2.jar;%LIB%\commons-logging-1.0.3.jar;%LIB%\commons-collections-2.1.jar;%LIB%\commons-lang-1.0.1.jar;%LIB%\cglib-2.0-rc2.jar;%LIB%\dom4j-1.4.jar;%LIB%\odmg-3.0.jar;%LIB%\xml-apis.jar;%LIB%\xerces-2.4.0.jar;%LIB%\xalan-2.4.0.jar


Suggested New CP Setting
set CP=%HIBERNATE_HOME%\hibernate3.jar;%JDBC_DRIVER%;%PROPS%;%LIB%\commons-logging-1.0.4.jar;%LIB%\commons-collections-2.1.1.jar;%LIB%\cglib-full-2.0.2.jar;%LIB%\dom4j-1.5.2.jar;%LIB%\ehcache-1.1.jar;%LIB%\log4j-1.2.9.jar;%LIB%\jdbc2_0-stdext.jar;%LIB%\jta.jar

SchemaUpdate.bat seems to have the same problem but I've not updated it as yet.

Thank you very, very, very much.

Finally managed to get some schema output!
