Java HotSpot Virtual Machine

Hi,

I am terribly stuck up at a point in my code where I need to do some passing around of strings.

I have a java program which passes a string to my C++ dll (through JNI).

In the C++ dll i convert thi string i.e. the jstring to a char* as follows:

char* cText = (char *)(*jenv)->GetStringUTFChars(jenv, jtext, NULL);

Here jtext is a jstring that comes from my java program.

Now, within my C++ dll I call my VC++ dll and pass cText to it where it expects an argument of the type char*.

But each time I make a call to the function in the VC++ dll, which looks something like this:

int intMyReturnVal2 = MyFunction2(0, cText, "D:\\audioJNI.wav",5,5,5,5,1);

THe program crashes. I get this error:

# An unexpected error has been detected by HotSpot Virtual Machine:

**************************************************************

could someone please help me with this? I have tried a lot of things to make it work, but in vain. I know that the problem is with passing the char* from my C++ dll to my VC++ dll, and that the JVM seems to be complaining about it, but dont knw how to fix it.

Instead of passing the string from java to C++ to VC++, I even tried to hardcode a char* during my call from C++ to VC++, but i get the same error.

Any help will be really appreciated.

Thanks
