> The issue is that I will be sending the string from a C++ socket, so I can't just use

wr.write(myString);)  I get the following at the INFO level, which is before any of my code

hmm, you need to write the length of the byte array of the string you
are sending instead of writing the
length of the string.
byte[] data = myString.getBytes( "UTF-8" );
