Urgent : Another kind of EXCEPTION VIOLATION ACCESS

Recommended Posts

my desktop app is using xFunction to access dlls of the card machine and reader.

I deploy my app in Jboss server with xFunction.dll in dll folder set by '-Djava.library.path=dll\'. and i put all my card machine and reader dll files in Windows/system32. So when i run my app and do a few trx, my app disappears and it crashes with JVM with error message like 'EXCEPTION VIOLATION ACCESS....problematic frame : ntdll.dll..........not only ntdll.dll, sometimes can be verify.dll in jdk1.5.0/jre folder...and so on

When i run my app in eclipse, everything is ok..no crash.........may i know whether  the root of cause is my code, or the card machine and reader dll files

Please give advice, THANKS...

No way to tell if it is your code or the reader's DLL. Simplify the problem. Write a simple application that doesn't use xFunction, making it more and more complex until you get a crash, then try to figure it out from there.
