OPENFIRE支持EMOJI(OPENFIRE 3.8.1版本)

用openfire搭建XMPP服务器时，客户端一发送emoji表情文字就会掉线，错误日志片段如下

2013.05.21 12:57:44 org.jivesoftware.openfire.nio.ConnectionHandler – Closing connection due to error while

processing message: <message type=”chat” to=”[email protected]” dateline=”1369112264.017495″><body>这里是

可以看到，在MXParser.java的第384行，出了问题，这里是XML的合法性验证代码，因为emoji表情文字的编码不在合法的XML字符范围内，所以只要将这里改掉，就可以正常收发emoji了将MXParser.java中的more函数改为如下：

@Override
	protected char more() throws IOException, XmlPullParserException {
		final char codePoint = super.more(); // note – this does NOT return a
												// codepoint now, but simply a
												// (single byte) character!
		if ((codePoint == 0x0)
				|| // 0×0 is not allowed, but flash clients insist on sending
					// this as the very first character of a stream. We should
					// stop allowing this codepoint after the first byte has
					// been parsed.
				(codePoint == 0x9) || (codePoint == 0xA) || (codePoint == 0xD)
				|| ((codePoint >= 0x20) && (codePoint <= 0xFFFD))
				|| ((codePoint >= 0xE000) && (codePoint <= 0xFFFD))
				|| ((codePoint >= 0x10000) && (codePoint <= 0x10FFFF))) {
			return codePoint;
		}
		throw new XmlPullParserException("Illegal XML character: "
				+ Integer.parseInt(codePoint + "", 16));
	}

重新编译得到openfire.jar,替换服务器上的openfire.jar,再重启openfire服务，就OK了
