Java网页聊天如何实现，问题如下：

改成下面的样子：

%@ page language="java" pageEncoding="GBK"%

html

head

titleMy JSP 'lab.jsp' starting page/title

/head

body

if(application.getAttribute("chat")!=null)

{ if(request.getParameter("mywords")!=null)

{ String mywords=request.getParameter("mywords");

mywords=(String)application.getAttribute("chat")+"br"+mywords;

application.setAttribute("chat",mywords);

out.print((String)application.getAttribute("chat"));

}

}else{

application.setAttribute("chat","");

}

form action="a1.jsf" method="post"

input type="text" size="30" name="mywords" value="我喜欢聊天"

input type="submit" name="sumbit" value="提交"

/form

/body

/html

1.要用post提交，否则中文乱码

2.out.print((String)application.getAttribute("char")); 这句你写错了，应该是chat不是char

3.你第一次运行的时候application.getAttribute("chat")肯定是空的，是空的话你又什么都不作，下次还是空的呀

急求一个JAVA编写的局域网聊天代码？不要求很复杂。只要可以在两台机子上简单的对话就可以。
