Question about broken pipe

Michael Szalay 8 May 2008 04:52:03
 
Hi all

I've got a question about an exception message I often see in the log of my Jetty installation (see stack trace below). Its in a servlet reading a blob out of a database and writing the byte-stream back into the servlet output stream. It works fine, I've never heard any complaints from users. Does
anyone know if this message can be ignored?

Thanks for an answer

Regards

Michael

 The big question is...

Is
ImageServlet.proces­sRequest(Unknown Source)
the line that sends the LAST item of data?

I myself would want to get to the bottom of it, to make sure there was no
possibility of data loss.

Are the clients standard Browsers or are they applets?

Is your servlet trying to close the Output stream (it ought not to).

 Yep, that's it.

Don't close the stream yourself, you don't even need to flush it. Jetty handles
all flushing and closing for you. And, in the case of 1.1 it does not close the
stream after each response.

"Michael Szalay" replied:


Yes, the servlet sends all bytes of the response.
Clients are all web browsers.

The servlet does a close() to its OutputStream. Is that a problem (e.g.
concerning HTTP 1.1)?

Thanks for the answer.

 Hi, Chris,

I also had this issue for a long tme. Thanks for pointing out the
problem. However, I have another question.

In order to optimize the response, I compress the data being sent back
to the browser. So, I have:

out = new GZIPOutputStream(re­sp.getOutputStream()­)
// send the data using out
...
// with gzip'ed stream, we have to close the output stream
//in order for the browser to see the html page
out.close();

So, as you see, I have to call the close() on the GZIP stream. I have
tested using firefox as the browser, if I don't close the GZIP stream,
the browser won't get/render the html sent as compressed.

But, as you mentioned, because of the close() call, I got occasionally
broken pipe in the log. Any thoughts how to tackle this?

Thanks,

Jian

 FilterOutputStream alwaysOpen =
new FilterOutputStream(­ resp.getOutputStrea­m() ){
public void close(){;}
};

out = new GZIPOutputStream( alwaysOpen );

 From the javadocs for GZIPOutputStream:

public void finish()
throws IOException
Finishes writing compressed data to the output stream without closing
the underlying stream. Use this method when applying multiple filters
in succession to the same output stream.
