Assuming you want char * on the native side (you may need more memory allocated if the string contains non-ascii characters),

String myString = "CURRENT_USER";
Pointer m = new Memory(myString.length() + 1); // WARNING: assumes ascii-only string
m.setString(0, myString); 

You can then use m wherever you need to reference the "native" string.

For wide strings (wchar_t *),

String myString = "CURRENT_USER";
Pointer m = new Memory(Native.WCHAR_SIZE * (myString.length() + 1));
m.setWideString(0, myString);
