How are you "sending" it?

Some general advice:

Java strings are *not* zero terminated. Java strings are length+char 
array.  You'll want to actually count the size of the C++ string before 
constructing the Java String.

Depending on how you're passing the character data around, you may be 
able to do that on either the C++ or Java side, though I would suggest 
the C++ side.

Also note that a char[] in C++ is not the same as a char[] in Java. 
char[] in C++ is more like (but not exactly) byte[] in Java.
