Throwing PL/SQL Exceptions to Java

Question

Hi, anyone have experience with calling a PL/SQL stored procedure from Java?
I am using the CallableStatement, but my issue is capturing error messages
thrown by the stored procedure. In the exception block of the stored
procedure I throw errors using the RAISE_APPLICATION_ERROR.
Will that raise an SQLException in Java, or does the error message get set to the CallableStatement interface's Warning message (accessed through CallableStatement.getWarnings();)? Or perhaps something else? If anyone has
some previous experience in this area, please let me know. Thanks,
Mac

Shravan,
Actually, I already know that that works. In fact, you can create two OUT parameters, on with the error code and one with the message. In your exception block you should be able to assign values to each one. When you do this, don't use the RAISE_APPICATION_ERROR procedure, for it will clear your OUT parameters.
The issue is that this does not raise a SQLException, which is what I would like to do. Since JDBC already has the facility to raise an SQLException with an unhandled error condition in a Procedure, I am wondering if RAISE_APPLICATION_ERROR allows programmers to pipe custom errors into the JDBC as SQLException objects. The reason I want to do this is because I would like my PL/SQL procedure to handle exception conditions internally, and deliver an error which is meaningful to consumer of the service provided by the PL/SQL procedure. I can accomplish this with an OUT parameter or two, but I'd prefer to send exception conditions out of the procedure as actual SQLExceptions, rather than out parameters.
