Re: [jetty-users] Continuations in Jetty 7? 
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.

I'm using the Jetty Hightide distribution extracted straight out from a
download and unless there's another jar I need,
jetty-continuation-7.1.6.v20100715 is in the Jetty lib directory.  I get
java.lang.IllegalStateException: !(Jetty || Servlet 3.0 ||
ContinuationFilter) as the error whenever I go to it, which comes when I
do a ContinuationSupport.getContinuation. I notice references to Jetty 6
stuff in the source for it, which is why I thought I needed the
jetty-util-6 jar.

    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

    regards

        I get now that I need the jetty-util-6 jar in there, but I'm having
        problems making Jetty use it.  First I just dumped it in the lib
        directory hoping Jetty would pick it up, but it didn't.  Then I
        tried it
        in my webapp's lib directory and no luck there either.  Then I tried
        adding it to the CLASSPATH env variable, but that didn't seem to do
        anything either.

        ContinuationSupport.class.getClassLoader().loadClass("org.mortbay.util.ajax.Continuation")
        seems to get a NoClassFoundException.  Where do I need to put the
        jetty-util-6 jar to get Jetty to load it so that part will work?

            How are continuations supposed to be used in Jetty 7?  When

        ContinuationFilter).  I
            have the ContinuationFilter on, but it seems to have
        initParameters
            for jetty6, partial, and faux continuations.  But I also look at
            ContinuationSupport and it seems to have references
            to org.mortbay.util.ajax.Continuation which is supposed to be
            renamed under the move to the org.eclipse package space.
          Can anyone
            give me an example of how to set it up?  I can't seem to
        find much
            on the wiki in relation to doing it under Jetty 7.
