然后修改setenv.bat文件
@echo off
rem -------------------------------------------------------------------
rem Setup environment for hibernate tools
rem -------------------------------------------------------------------
set JDBC_DRIVER=C:\Opensource\lib\mysql-connector-java-3.1.7-bin.jar
set HIBERNATE_HOME=C:\Opensource\hibernate-2.1
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-1.0.3.jar;%CORELIB%\commons-collections-2.1.jar;%CORELIB%\commons-lang-1.0.1.jar;%CORELIB%\cglib-2.0-rc2.jar;%CORELIB%\dom4j-1.4.jar;%CORELIB%\odmg-3.0.jar;%CORELIB%\xml-apis.jar;%CORELIB%\xerces-2.4.0.jar;%CORELIB%\xalan-2.4.0.jar;%LIB%\jdom.jar;C:\Opensource\hibernate-extensions-2.1\tools\hibernate-tools.jar;
然后运行hbm2java c:\sample\org\hibernate\sample\*.xml --output=c:\sample\
结果总提示空指针的exception，那位朋友能帮忙看一下，谢谢了！
