Jetty add additional stuff inside the response header???HELP

[kenryu]

I have a problem when I tried to send the response back from a Servlet. I'm using Jboss 3.0.3 that comes with Jetty. The exception that I got is
10:55:35,526 WARN [jbossweb] WARNING: Invalid length: Content-Length=17 written
=19 for http://localhost:8080/

The strange thing is if I add 2 into the message.length then it will stop complain. So When I'm sending String with length of 17 and I add 2 = 19 it will stop complaining. This has caused my POST connection a BIG problem. Anybody especially JBOSS developer know how to handle this????

This is the snippet of the code
==============================


message = "somemessage";
response.setContentType("text/plain");
res.setContentLength(message.length());
PrintWriter out = response.getWriter();
out.println(message);

There is a mismatch between the amout of data that you are declaring you are going to send, and the amount of data that you are actually sending - Jetty issues a warning.

It looks like you are setting contentLength to 17 and then sending 19 bytes - hence the warning.

If you set contentLength to the correct value (19), the warning goes away.

What is the problem ?

Do you have to set the contentLength ?

Do you think that Jetty is miscalculating the amount of content that you are actually sending ?

OK - now I've looked at the code snippet !

I suspect that you are probably need to account for a newline and maybe a terminator of some kind at the end of your message - I'll check with the powers-that-be.

Or just don't bother setting the content length at all!
Jetty will handle that for you if your client in HTTP/1.1

you only really need to set your own content length if you have lots of http/1.0 clients.

hi All;
Thank's for the reply. Actually those code above is J2ME code (MIDlet). I'm trying to make a POST Connection with servlet that in turns will make connection to session bean. Have anybody find out about this??Help!

Thank's

By the way the reason why I have to add 2 because when I'm sending a message with a length of 17 it will complain : 10:55:35,526 WARN [jbossweb] WARNING: Invalid length: Content-Length=17 written
=19 for http://localhost:8080/
so that's why I decided to add 2 and it will stop complaining. Anybody?? help..:)

did you read my answer ?

You are probably adding one byte because you are using printLN which will append a newline.

The other byte is probably a terminator.

As Greg says, there is probably no need for you to explicitly set the ContentLength anyway.
