Hello,

    I am using JBuilder Foundation 3.5 and DataGateway to access a
Paradox table under Windows NT 4 (SP5). I can setup the connection
correctly but when I try to execute a query (ie SELECT), I get a Dr.
Watson error message concerning Access Violation with javaw.exe. First I
tryied to find the bug in my application and then, really confident
about my code, I tryied to run a sample application provided with
DataGateway. The same error occured, confirming that the problem is not
my program but probably a bug with JBuilder or DataGateway (or both
together). I tryied to reinstall both but the bug was still existant. I
tryied to access my database through ODBC and it was successful.
However, the ODBC solution does not provide portability on other OS and
is just a temporary alternative. I would like to know if somebody else
encountered that bug and what can I do about it?

Here is the detailed error in the Dr Watson's log file (sorry about the
French) :
