JDBC - Closing Statements and Closing ResultsSets

[Dirk Struyf]

Hello,

     I'm using servlets to query an Oracle database, and encountered on several
occasions an oracle message : too many open cursors.

     I implemented a resultset.close() statement, but this did leave some
cursors open. ( I accessed Oracle directly to retrieve details on the open
cursors.)

     I replaced the resultset.close statement with the following piece of code
and my oracle database query shows me now that the cursors are closed directly.

     This is what I did:

     public void close(ResultSet x)
     { // first close the related statement, if it can be found
       Statement y = null;
       try      {   y = x.getStatement();
                    System.err.println("...Statement retrieved.. ");
               }
       catch (Exception e) {  System.err.println("ERROR: No statement found or
closed");
                }

       if (y != null)  {
       try        { y.close();
                  System.err.println("Statement Closed");
                  }
       catch (Exception e) { System.err.println("ERROR: Statement Closed
INCORRECT ");
                }
        // then close the actual resultset
       try        {   x.close(); System.err.println("ResultSet Closed");
                  }
       catch (Exception e) { System.err.println("ERROR: ResultSet Closed
INCORRECT ");
                }

     }}

Any comments, suggestion, on this ?

Dirk
