Hi, I am calling C++ methods from Java. Everything is working fine except when I make 2 calls simultaneously. For Example : I have a native method in Java and it's implementation in C+ by the name MyFunc(int i, String s); When in the main method I am calling : MyFunc(1,"A"); MyFunc(2,"B"); I am getting a Memory "Read" error. Any help on resolving the error would be of great help. Raj Sun Certified Java Programmer.
