You just have to register two different out parameters in this way

callableStatement = dbConnection.prepareCall("{call getTWOCursor(?,?)}");

callableStatement.registerOutParameter(1, OracleTypes.CURSOR);
callableStatement.registerOutParameter(2, OracleTypes.CURSOR);

// execute getTWOCursor store procedure
callableStatement.executeUpdate();

then read both Recordsets in this way:

rs1 = (ResultSet) callableStatement.getObject(1);
rs2 = (ResultSet) callableStatement.getObject(2);

Why have you got two ResultSet and how are they related? If there's a good reason to return two (which frankly i doubt) then you can return ResultSet[]

I've never heard about returning of  ResultSet[] ?! But I'm agree that if there is a need of returning of  ResultSet[], then there is something wrong in the design of the application.

I mean to say what if the procedure has the following set of statements.

create procedure sp_get
as
begin
select uname,password where dept='cse'
select count(*) from dept
end

Those are two independent statements and are not returned by the procedure, just used in it.

It's OK. If he return them as out parameters then there is no problem to read them as I showed in my first comment. I think that it's normal and right.
Ignoring that the second parameter is not cursor, it is "Int".
I mean in the example "sp_get" that the author posted.

Yes, 'if'. In the example posted nothing is returned.

I think that it's normal and right
There, i have to disagree. If you can show me several examples of where more than one cursor is returned from a procedure or function, then i would reassess it.

The question asked is "How to return 2 recordsets IN JAVA" (my emphasis). The answer to that is to use ResultSet[], IF it seems legitimate
