Armin: SequenceManagerHighLowImpl is generating the primary key which is stored in Oracle 9i as NUMBER. Data conversion is required for two other regular fields. Where exactly is the bug? When will it be fixed? Also is it a common practice to boundle ojb.jar inside myejb.jar file?
Thank you very much!

Then it seems that the conversion was not done in some cases. regards, Armin ----- Original Message ----- From: "Lucy Zhao" <[EMAIL PROTECTED]> To: "'OJB Users List'" <[EMAIL PROTECTED]> Sent: Friday, February 21, 2003 4:42 PM Subject: RE: ClassCastException in OJB 0.9.9 with Oracle 9i > I have three java data types in the object.
