:-) With block IO, I can do this, but Mina is a NIO framework . If I use Mina , I should use NIO, of course NIO is prominent.
I can use a delimiter to delimit the messages easily . I just want to know what's the reason which lead to this result, so I have this question, Thank all of you. :-) hpq852 2006-07-24 发件人： Maarten Bosteels 发送时间： 2006-07-24 21:40:28 收件人： [email protected] 抄送： 主题： Re: Re: About Mina Question, Could you help me ?

Maybe it appears to work on localhost or on your local lan but I would certainly not depend on it. Why do you need this ? Would using a delimiter to delimit your messages not be easier ?
