有点晕，楼主多看API。

能不全是代码吗？

全是代码，还没格式化，谁看的懂啊，晕

额。。。。
面对这一段代码，我表示，很有压力，谁能给我看完的勇气。。。

很难看完，当场就晕 了

代码没看，但异常看到啦 ^_^,在Tomcat文件夹下按Ctrl+F,然后搜*.ser，把搜出来的都del,应该就OK了！

我以前也遇到过，不过你的代码太多了，没法看呀
你去 http://jacky1118sally.iteye.com/admin/blogs/1128332 看看我写这个文章有用么，希望有帮助

你这个问题我刚碰到过  是因为你在客户端有多个socket和ois和oos   导致前一个读写和后一个读写混乱  建议你用一个
