Well I have a little more information on this issue if someone would be kind enough to help... The exact version of Oracle that I am using is 8.1.7.0.0... So I wrote a very simple CMP bean, that is to store a custom object that is Serializable (this object is very simple and only contains 2 Strings and one integer), and I get the same error as below for the new CMP bean as well... I tried changing the type in the data mappings in standardjbosscmp-jdbc.xml to LONG RAW and still no luck with retrieving the object... I am now going to try the CMP examples... Hopefully they work... I have the code for the CMP bean and the tests that I just wrote if that would be of any help... This worked on the RI!
