Memory exeception

Hi

I have a problem in processing large numbers of rows in ResultSets.
Here's the code fragment where the problem occurs:

...
    ResultSet rset = stmt.executeQuery( "select ... from ... where ...
order by ..." ) ;
    while(rset.next() )
    { // Process the row }
...

The query addresses some 100'000 rows. When stmt.executeQuery() is
executed suddenly an exception occurs.
The same program works fine with other JDBC drivers.

Any ideas ?

Greetings
Peter
