在hibernate-extensions中使用hbm2java出错

C:\test\ext\tools\bin>hbm2java c:\test\com\dlsp\*.xml --output=c:\test\
信息:
HIBERNATEHOME_HOME set to C:\test\hibernate-3.0
HIBERNATEHOMETOOLS_HOME set to C:\test\ext\tools
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/hibernate/MappingException

hibernate 版本是3.0的， 上面目录 ext即hibernate-extension目录

急等各位高手赐教！！！
