Servlets- How to read from a servlet output(out.println)

Question

Could you please help me in reading a servlet output by using a java class/servlet. Scenario : I have a servlet which prints "Hello World" say from out.println("Hello World).

I need to capture the output of that servlet in a java/servlet file and perform a task

Appreciate for any leads on this.

Thanks

Sample Snippet would be of more help. Thanks – pal Sep 08 '11 at 12:42 — pal, Sep 08 '11 at 12:42

if out is the response stream then you can make call using HttpURLConnection to read the output it prints on response.

We can use filters. And after "chaining" we can use response object to read the response string.

chain.doFilter(request, response);

There is a similar question with full description. As it contains an extensive description, I am not repeating it here again.

You forgot one important additional step. There is no standard way to read the body from `HttpServletResponse` directly. There's no `getInputStream()` method or something. – BalusC Sep 08 '11 at 12:18
