Re: [jetty-users] Re: error while building jetty 8 from svn
|
Pieter,
I've tested all the glassfish samples and they're all
working fine with head of jetty-8.
You may notice an exception with the async chat app if you
close the page or browse way. This is due to this code
in the chat app:
for (AsyncContext ac : queue) {
try {
PrintWriter acWriter = ac.getResponse().getWriter();
acWriter.println(cMessage);
acWriter.flush();
} catch(IOException ex) {
System.out.println(ex);
queue.remove(ac);
}
}
This code tries to write the async context representing the
closed connection and discovers that the connection has
been closed. Note that PrintWriter specifically cannot
throw IOException, so the try/catch statement in this
code is a bit pointless. It would have been more correct
to do the println() and then call checkError() to see if
the println succeeded or not.
Now, the other factor at play - and the reason you can see
an exception - is that Jetty actually throws an
UncheckedIOException which is a RuntimeException when
the PrintWriter implementation encounters an error. We
do this for the very reason that 99% of people just don't
check the error on PrintWriter IO operations. I think
perhaps we need to make the throwing of the UncheckedIOException
configurable, so I've raised this issue for it:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=318551
Thanks for pointing out the javaee RI sample apps, it
was quite illustrative running them, I fixed up a few
little problems they revealed.
cheers

Dear Jan,
Are you also working on the servlet 3.0 async code?
Since running the glassfish chat example
(http://blogs.sun.com/enterprisetechtips/entry/asynchronous_support_in_servlet_3)
doesn't seem to work.
Kind regards,
Pieter

Pieter,
Thanks for that! I've updated the jetty-8 repo.
Just a word of warning - I'm doing a lot of refactoring work in the
jetty-webapp and jetty-annotation modules, so things might be a little
unstable for a day or two.
cheers

Dear all,
after changing tests/test-loginservice/pom.xml
- <version>7.1.5-SNAPSHOT</version>
+ <version>8.0.0.M1-SNAPSHOT</version>
and removing <module>jetty-jsp-2.1</module> from the main pom.xml,
the build seems to work fine again.
Kind regards,
Pieter
