I tried out the test.war chat app and that works. Although I'm not certain I understand why it works. Which Continuation type does it use? Servlet3? Jetty6? Faux? It doesn't seem to have the Jetty6 util jar in there, so I'm not sure how it's getting past this:

static

         boolean servlet3Support=false;

         Constructor<? extends Continuation>s3cc=null;

try

             boolean servlet3=ServletRequest.class.getMethod("startAsync")!=null;

             if (servlet3)

                 Class<? extends Continuation> s3c = ContinuationSupport.class.getClassLoader().loadClass("org.eclipse.jetty.continuation.Servlet3Continuation").asSubclass(Continuation.class);

                 s3cc=s3c.getConstructor(ServletRequest.class);

                 servlet3Support=true;

         catch (Exception e)

{}

         finally

             __servlet3=servlet3Support;

             __newServlet3Continuation=s3cc;

         boolean jetty6Support=false;

         Constructor<? extends Continuation>j6cc=null;

try

             Class<?> jetty6ContinuationClass = ContinuationSupport.class.getClassLoader().loadClass("org.mortbay.util.ajax.Continuation");

             boolean jetty6=jetty6ContinuationClass!=null;

             if (jetty6)

                 Class<? extends Continuation> j6c = ContinuationSupport.class.getClassLoader().loadClass("org.eclipse.jetty.continuation.Jetty6Continuation").asSubclass(Continuation.class);

                 j6cc=j6c.getConstructor(ServletRequest.class, jetty6ContinuationClass);

                 jetty6Support=true;

         catch (Exception e)

{}

         finally

             __jetty6=jetty6Support;

             __newJetty6Continuation=j6cc;

         Class<?> waiting=null;

try

             waiting=ContinuationSupport.class.getClassLoader().loadClass("org.mortbay.util.ajax.WaitingContinuation");

         catch (Exception e)

         finally

             __waitingContinuation=waiting;

It also doesn't seem to use the ContinuationFilter. My lib directory looks like:

I used to have the ContinuationFilter in there, but I took it out when I saw the example didn't have it.

Kevin,

The test.war webapp in the hightide webapps directory uses the
continuations. In particular the ProxyServlet uses them, so try
accessing the test webapp and the proxy test and confirm it is
working for you, then have a look at the structure of the webapp
and compare it to yours. FYI here's the source of the ProxyServlet:
http://download.eclipse.org/jetty/stable-7/xref/org/eclipse/jetty/servlets/ProxyServlet.html

If you still can't figure it out, post the source of your servlet,
your web.xml and a list of what's in your WEB-INF/lib to this list.

cheers

Kevin,

You need to copy the jetty-continuation jar into WEB-INF/lib of your
webapp. Its just in $JETTY_HOME/lib so its inside the distribution.
Possibly we should move it out of there to avoid confusion.

Kevin,

Here's 2 pages on eclipse that talk about continuations in
jetty-7:

1.
http://wiki.eclipse.org/Jetty/Starting/Porting_to_Jetty_7#Continuations

2. http://wiki.eclipse.org/Jetty/Feature/Continuations

If you code to the jetty-7 api discussed in link 2 above, then
it will work on jetty-6 and jetty-7 (and any servlet 3.x
container).

You need the jetty-continuations-7.x.jar in your webapp's
WEB-INF/lib.

If you code to the jetty-7 api and then deploy in jetty-6
you'll get
a warning about the ConfigurationFilter (used for backward
compatibility) not being configured. Here's the reference
for it:
http://download.eclipse.org/jetty/stable-7/xref/org/eclipse/jetty/continuation/ContinuationFilter.html

Then I tried

ContinuationSupport.class.getClassLoader().loadClass("org.mortbay.util.ajax.Continuation")
