Hi,

maybe somebody can help me out with this:

I have a C++ DLL which is called from a Java VM which works fine. I can
do callbacks from C++ to Java within the thread created by the VM.
I store the reference to the VM via env->GetJavaVM( &globalVM ) from
this thread in a global variable.

int CALLBACK func(LPVOID pCmd, LPVOID pParam)
{

   JNIEnv* localEnv;
   int rc = globalVM->AttachCurrentThread((void**) &localEnv, NULL);

   rc = globalVM->GetEnv( (void**)localEnv, JNI_VERSION_1_2 );

   if( rc == JNI_EDETACHED )
       printf("GetEnv failed: thread not attached\n");
   else
       if( rc == JNI_EVERSION )
           printf("GetEnv failed: wrong jni version\n");
   else
       if( rc == JNI_OK )
           printf("GetEnv ssucceded\n");

   localEnv->ExceptionClear();
   ...

At the last command, I get an unhandled exception in the Java VM.
However, the AttachCurrentThread and the GetEnv seem to work. At least,
they don't give negative numbers.
What am I doing wrong.

Any help appreciated,

Rainer
