     最近公司做一个基础tapestry3.0的应用的二次开发，Tomcat的后台时不时的抛如下异常：

由于自己也是第一次使用tapestry，貌似国内用的公司也不多，资料比较难找。

 

 

 这是在网上找到的貌似是一个老外给的治表不治根的解决方案。

 

    I saw that error a lot in my existing 3.0 application. In my case I
eventually tracked it down to a low level socket write error (my server was
reporting that the browser shut the socket before it finished sending the
full stream). I'm sure there's another underlying cause e.g. the browser
didn't do that on a whim, but I couldn't figure out how to fix it.

I ended up having to superclass BaseEngine and turn the error
message into a noop just to keep my log from filling up with that particular
error message.

If you want to get rid of it, superclass BaseEngine, and override
reportError like this.

public void reportException(String reportTitle, Throwable ex) {
String name = ex.getClass().getCanonicalName(); //ex.getClass().getName();
if (name.endsWith("ClientAbortException")) {
Log.debug("Threw one of those annoying IE only flush
errors");
return;
}
super.reportException(reportTitle,ex);
}

 

 

就是捕获这个异常，只在后台打印相应的信息。 在一定程度上减轻服务器的负担，暂时也没找到根本的排队异常的方法 。

 请遇到相同问题的高手能指点一下。
