Access Violation calling GetMethodId

Question

Hi !
I'm getting an access violation on the jvm.dll when trying to execute a call from the native side. Well, in fact, the exception is raised when a try to get the method reference, by calling GetMethodId ().
The _javaClass variable is a class attribute and is correctly initialized since I'm being able to execute other calls.
Can somebody help me, please ?
This is the code:
void JavaBridge::pushJava (const char* str)
// To java push
// Get some variables
jmethodID javaMethod;
jstring javaString;
// Get the string     
javaString = _env->NewStringUTF(str);
if (javaString == 0) {
JCB_ERROR ("JavaBridge::pushJava: Out of memory...");
return;
// Get the process() method
javaMethod = env->GetMethodID(javaClass, "process", "(Ljava/lang/String;)V");
if (javaMethod == 0) {
JCB_ERROR ("Can't find CppBridge's process() method.");
return;
// Call it
env->CallVoidMethod (javaObject, javaMethod, javaString);

Answer 1

I think your class reference is null.
