Javolution string UDP

Question

I'm new to Javolution and C/C++ . But I really like it so far and I think makes the code much cleaner.

I have been playing with the UDP example that can be found here http://javolution.org/target/site/apidocs/javolution/io/Struct.html

It is working well except when I use UTF8String. Is this normal.

So for I have a Struct like this

public class UserTest extends Struct
{
    public Unsigned8 age  = new Unsigned8();
    public UTF8String name  = new UTF8String(8);
}

then i have another class that sends via udp the struct

ByteBuffer buf = ByteBuffer.allocate(1400);
DatagramChannel channel = DatagramChannel.open(); 
channel.connect(new InetSocketAddress("localhost", 54300));
buf.clear();
buf.put(userStruct.getByteBuffer());
buf.flip();
channel.write(buf);

Now on the otherside of the connection I have the following

channel.receive(buffer);
buffer.flip();
userStruct.getByteBuffer().put(buffer);
System.out.println("Do I have a name >>>> "+ userStruct.name.get());
System.out.println("Do I have an age >>>> "+ userStruct.age.get());

Now this doesn't work but I remove name and just keep age then I can retrieve the value of age?

Is it possible to send String via Struct over the network?

Thank you, Anthony
