How to redirect a Java ResponseWriter?

For debug reasons, I want to see the ouput of my ResponseWriter directly in standard output. Because the response will be processed by JavaScript I am not able to see the outpu开发者_如何学JAVAt there.

Is there an easy solution to redirect the ResponseWriter to standard output?

How about this?

ResponseWriter rw1, rw2; // ...
rw2 = rw1.cloneWithWriter(new PrintWriter(System.out));

Documentation for ResponseWriter

• http://developers.sun.com/docs/jscreator/apis/jsf/javax/faces/context/ResponseWriter.html#cloneWithWriter(java.io.Writer)

Use whichever writer your find most convenient

And finally, system.out.

There is - you can wrap your response and writer objects. But in this case there is a better solution: use Firebug. It will tell you what the response has been.
