关于mina的过滤器问题

[xk1982]

public class Xml2ObjFilter extends IoFilterAdapter{
	
	private static Logger logger = Logger.getLogger(LockManager.class);
	private FunctionMapping functionMapping;
	
	public FunctionMapping getFunctionMapping() {
		return functionMapping;
	}

	public void setFunctionMapping(FunctionMapping functionMapping) {
		this.functionMapping = functionMapping;
	}

	public void messageReceived(NextFilter nextFilter, IoSession session,
			Object message) throws Exception {
		
		String xml = (String)message;
		//读出读信息
		LoadHead head = (LoadHead)Xml2Obj.fromXML(xml, LoadHead.class);
		//取出功能号
		String funNum = head.getHead().getFunNum();
		//从映射关系中找出所对应的对象
		String beanName = functionMapping.getBeanMapping().get(funNum);
		//反射出class		
		Class clazz = null;
		Object obj = null;
		try{
			clazz = Class.forName(beanName);
			//将xml转成对象
			obj = Xml2Obj.fromXML(xml,clazz);
		}
		catch(Exception e){
			logger.error(e);
		}
		nextFilter.messageReceived(session, obj);
	}

	
	
	
}

我定义了一个过滤器，从客户端发送过来的数据是可以进行过滤的，请问，服务器如果像客户端发送数据，又如何进行过滤呢？需要在这个类里加上什么方法？
