EXCEPTION_ACCESS_VIOLATION when loading DB2 driver

Question

Hi,
I'm currently developing an executable jar application. I've got a problem in connecting to the DB2 server after packaging the application into a jar file. Below is the error that I encountered:
# An unexpected error has been detected by HotSpot Virtual Machine:
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6d6c9a1f, pid=2296, tid=2260

# Problematic frame:

    } catch (SQLException sqle) {

    return data;
}This code actually worked fine when I ran it from VisualAge for Java environment.
I'm currently using J2SDK version 1.4.2_10 and J2RE version 1.4.2_10.
Appreciate any help that you all can suggest. I've been looking for this error on the web. Seems like this has been a known and common problem but I couldn't find the working answer so far. Thank you in advance for any help.

Hi Russel,
Thanks for the reply. I've executed the jar file using the -Xcheck:jni as follows:

        at java.awt.EventDispatchThread.run(Unknown Source)I recognized that the error appeared during the execution of function "forName(driver)", which is exactly what I predicted before. Strange that this function worked well when executed from the development software (before packaging it into jar file). Is there a difference in the way the program works as executable jar file and as the file in the development sofware?
And regarding the JDBC driver, I did try another driver, which was the JDBC type 2 and 4 driver. But when I ran the application, there's an error saying that the DB2 server does not support type 2 or 4 JDBC driver. Seems like I have no other choice but to use this driver.
Do you have any suggestion on how to make the driver work as an executable Jar file? Meanwhile, I'll try to report the bug for this driver. Thanks....
