我用weblogic连接sql,通过测试,connection successfully,但是当我在程序中引用时老是不行
具体提示错误为:
javax.transaction.TransactionRolledbackException: EJB Exception: : javax.ejb.EJBException: nested exception is: java.sql.SQLException: Failed to Generate Wrapper Class.
Nested Exception: java.lang.RuntimeException: Failed to Generate Wrapper Class
这是怎么回事,请赐教
