Have you tried using putChar method of ByteBuffer?

ByteBuffer buf = ByteBuffer.allocate(1024);

for (char ch : myChars) {
  buf.putChar(ch);
}

Several ways eg

char[] c = {'1', '2'};
String str = new String(c);
ByteBuffer bb = Charset.defaultCharset().encode(str);

or

ByteBuffer.wrap(str.getBytes());

Only comment, more than likely you'll want to be explicit about what character set you are using to encode your character array instead of just using the default charset. Your server is probably expecting a specific one, and you don't want to be prey to the whims of whichever platform and locale is running your code. – Charlie Dec 20 '12 at 07:54
