middlegen不能生成java文件

[mwx2008]

我是在eclipse环境下使用middlegen的，可以生成hbm.xml,但不能生成java文件.
错误提示：

This may be intentional from the design of the database, but it may also be because you have incorrectly defined the relationships. It could also be because the JDBC driver you're using doesn't correctly implement DatabaseMetaData. See the samples (for an example on how to define relationships) and verify that your driver correctly implements DatabaseMetaData.

针对hibernate,middlegen确实只能生成hbm文件，如果需要生成pojo，可以使用hbm2java工具
