Need help with callableStatement()

[penciled]

I have a PL/SQL procedure that SELECTs lists of data from several tables. I want to be able to use this with JSP. I've read about people using CURSORS to retrieve multiple tuples from database queries. I'm new to cursors and callableStatements.
Can someone please walk me through (examples would be nice) this process?
My procedure is fairly basic. I give it a userID and/or location that are used in the WHERE clause and it will list all the information for that user and/or location.
I think this is how it's supposed to be done-> but I'm not positive:
callableStatement cs = con.prepareCall ( "{ call myProc ( ?,?, ? )}" );
cs.registerOutParameter( 1, CURSOR );
cs.setString( 2, uNum );
cs.setString( 3, location );
cs.execute();
resultSet rs = cs...?
while( rs.next() ) {
//List data
}
Is this right?

I was told that I needed to do this:
ResultSet rs = ((OracleCallableStatement)cs).getCursor(1);
...so I added the Oracle stuff- I had to include <%@ page import=&quot;oracle.jdbc.driver.*&quot; %> as well, but now I'm getting several errors like this one:
C:\Tomcat\work\localhost\examples\jsp\Henry\telcom\tReports\tCreateReport$jsp.java:0: The method oracle.jdbc2.Clob getClob(int) / getRef(int) / getBlob(int) / getArray(int) declared in class oracle.jdbc.driver.OracleCallableStatement cannot override the method of the same signature declared in interface java.sql.CallableStatement. They must have the same return type.
package org.apache.jsp;

I tried a few other things, but I'm not sure what I'm supposed to do with that. Any ideas?
Here's my code:
cs = con.prepareCall ( &quot;{ call myProc ( ?,? )}&quot; );
cs.registerOutParameter( 1, OracleTypes.CURSOR );
cs.setString( 2, uNum );

cs.execute();
rs = ( ( OracleCallableStatement ) cs ).getCursor( 1 );
