shabarish vai, please read my reply to you in your previous post regarding your choice of subjects.

The title "jdbc" in a forum of all JDBC questions is of little value.

I see a whole list of Oracle error codes there (12500, 12538, 12560, 508). Go to for example http://www.ora-code.com/ or look in the Oracle documentation to find out what those error codes mean; they will most likely give you a clue to what is going wrong.

Or just try typing in for example "ORA-12538" in Google and see what you find.
