Hi Shyam,
The
JDBC Developer's Guide and Reference (part of the Oracle documentation) contains this information. One of the places you can access the Oracle documentation from is:
http://tahiti.oracle.com You need to register with the site first, but registration is free.
Unfortunately, the mapping is not consistent, and depends on things like
the Oracle database version you are usingthe EJB container you are usingthe JDBC driver you are using Excuse me, but I couldn't find any of those details in your post, so what I am about to say may prove to be totally incorrect for your situation.
Usually, the (Oracle) DATE datatype maps to either "java.sql.Timestamp" or "java.sql.Date".
Good Luck,
Avi.
