need help in making dll using in jogl's display method

Hello,

i would like to create a dll to an existing C code.
i created the jni C and H code, i compiled it, i created a test code:

static{
System.loadLibrary(“helpsm”);
HelpSMServices.updateMtx2();
HelpSMServices.updateMtx2();
}

this works fine…

when i want to make this calls from the jogl display method i got this:

An unexpected error has been detected by HotSpot Virtual Machine:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6d73c55d, pid=1560, tid=3080

Java VM: Java HotSpot™ Client VM (1.5.0_05-b05 mixed mode, sharing)

Problematic frame:

An error report file with more information is saved as hs_err_pid1560.log

What can i do? (i’m using visual studio 6 for the dll creation)

Check the created log file (hs_err_pid1560.log in your example). That might shed some light on the situation…
