我用jbuilder9和weblogic7作了个CMP,数据库用的是Sql Server 2000,引擎用的是jdbcodbc。部署成功后，用jbuilder生成了一个客户端测试程序，结果可以执行ejbCreate(...)函数，却不能执行findByPrimaryKey(..)，我都快哭了，这CMP出的问题让你都不知道去哪里找毛病，给的提示如下：javax.ejb.FinderException: Problem in findByPrimaryKey while preparing or executing statement: 'weblogic.jdbc.rmi.SerialPreparedStatement@5dc941':

那位大师有这方面经验能不能指点一二，谢谢。
