Here is an example, including the style for
processing all possible returns from a procedure
or complex SQL. This is a PreparedStatement,
but the same is true for a Callable Statement.
Just do the getXXX() calls for the output parameters
after the processing loop:

       boolean getResultSet = ps.execute();

       // handle all resultsets and/or update counts
       while (true)
       {
           int updateCount = -1;
           ResultSet r = null;

           if (getResultSet)
           {
               r = ps.getResultSet();
               while (r.next());
               r.close();
           }
           else
           {
              updateCount = ps.getUpdateCount();
           }
           if ((r == null) && (updateCount == -1))
           {
               break; // done with loop
           }
           else
             getResultSet = ps.getMoreResults();
      }
