I'm developing a DLL for Symbian for using in Java-programs. In the DLL (C++) I create a thread, listening on a socket for incomming data. When data is received I want to make a Javacallback. If I make a Callback out of the thread (in JNI-Calls) it works fine but in the thread I get an Kern-Exec 3 (nullpointer-error i think).
It crashes here (before trying to do the callback itself)
(*glob_jvm)->AttachCurrentThread(glob_jvm, (void**)&local_env, NULL)
Without the JNIenvironment-pointer local_env its not possible to call a function in Java.
I hope somebody can help.
