How return char array from native method to Java?

[Robert Paris]

I have a JNI method that creates a char[] array and then will return it do the java program that called it. how do i do this? Do I have to create a jcharArray? how do I do that?
Basically what I want to do is: (pseudo code)

char myArr[16] = { 'f', '3' };
jcharArray result = new jcharArray[ sizeof( myArr ) ];
for ( int i = 0; i < sizeof( myArr ); i++ )
    result[ i ] = myArr[ i ];
return result;

How would I do something like that?
Also, related:
1. Can I return a jobject (or something else) for an object of a non-"standard" class? For example, IP_ADAPTER_INFO (found here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/iphlp/iphlp/ip_adapter_info.asp )
2. Anyone know of a really good JNI explanation site? The Sun stuff is not the best.

Well, I finally figured it out. Here's the code for anyone who's interested:

JNIEXPORT jbyteArray JNICALL 
Java_MyClass_getByteArray(JNIEnv *env, jobject obj) 
{
//CREATE A NEW BYTE ARRAY OF SIZE 6
jbyteArray firstMacArray = env->NewByteArray( 6 ); 

//GET THE "EMPTY" ELEMENTS OF MY JAVA BYTE ARRAY
jbyte *bytes = env->GetByteArrayElements( firstMacArray, 0);

//LOOP AND ADD ALL THE ELEMENTS
for ( int i = 0; i < sizeof( pAdapterInfo->Address ); i++ )
{
//Address IS A BYTE ARRAY
bytes[ i ] = pAdapterInfo->Address[ i ];
}
//ADD THE BYTES COLLECTED TO THE JAVA BYTE ARRAY
env->SetByteArrayRegion(firstMacArray, 0, 6, bytes );

//NEED TO RELEASE THE BYTE ARRAY
env->ReleaseByteArrayElements( firstMacArray, bytes, 0 );

return firstMacArray;
}

That's it! However: does anyone know if there's any cleanup I need to do? Is there anything else I need to do to make sure the jbyteArray is returned but can be garbage collected later and that there are no "leaks?"
