Hi,
I need a working example of Jetty web server, embedded inside my application.
Tried the example from here:
http://jetty.mortbay.org/xref/org/mortbay/jetty/example/OneContext.html
But it doesn't work, possibly because it is for v6, and I have v7.
I want one (multithreaded) method to handle all the HTTP requests.
Thanks!

To quote dpkg:

>>
 Look buddy, "doesn't work" is a vague statement.  Does it sit on the couch all day long?  Does it procrastinate doing the
             dishes?  Does it beg on the street for change?  Please be specific!  Define 'it' and what it isn't doing.  Give us more
             details so we can help you without needing to ask basic questions like "what's the error message?".

Doesn't work: waiting for the response forever.
Opening another port shows nobody is listening.
Opening the port I attached the server to causes the browser to wait forever and never show any page.

Well certainly a default maven build creates a lot of stuff, but i got it started with the following command (your paths will start differently, but should end the same) and don't forget to include servlet.jar:
java -classpath /bk/goose/tecra8000/home/java/java-libraries/httpunit-1.6.2/jars/servlet.jar:/home/goose/.m2/repository/org/mortbay/jetty/jetty/6.1.18/jetty-6.1.18.jar:/home/goose/.m2/repository/org/mortbay/jetty/jetty-embedded/6.1.18/jetty-embedded-6.1.18.jar:/home/goose/.m2/repository/org/mortbay/jetty/jetty-util/6.1.18/jetty-util-6.1.18.jar org.mortbay.jetty.example.OneContext

Yes, I know.
And it is leaking connections.
And you are trying to help me here:

So now I'm also trying to use Jetty instead, maybe this will help.

I'm not yet convinced it is :)

Moved to Jetty v6 and it works like in the example.

To close HTTP connection, I added a call to flush() and close() on the output stream.

>>Found out myself I needed to close and flush the output buffer

Can you explain that please?

Yeah sure. When I moved the code to Jetty, and started in, the connection number started climbing too.
I opened the browser on that page and it said "Waiting for [server]..." and the animation kept running, that is it was still running the page. However, I wrote all what I wanted and finished processing it.
So I realized that if my handler doesn't flush and close the output stream, then the server thread that calls it won't either. Frankly I expected more from it, especially since no example I've seen implicitly does that.

So basically I added, in the end of the handle(...) method in my Handler, the following code.

ServletOutputStream out = response.getOutputStream();
out.flush();
out.close();
response.flushBuffer();
