[T5.2] Live class reloading not working with jetty
Since we upgraded to T5.2, live class reloading has not worked correctly, however if we downgrade it works fine. We're using Jetty kicked off using the runjettyrun plugin for Eclipse.
When making just a simple tml change, using the running application again has a long pause before it does anything, and after a few requests it falls over out of permgen space.
All of our developers are experiencing this, and it's a real shame that one of the major strengths of Tapestry is not working for us anymore. Is there something I need to change to get live class reloading working with T5.2?
Thanks,
Andy

Hi All,
I have a small javascript function that ideally I'd like to include
inline in my page:
<script type="text/javascript">
<![CDATA[
function check(element) {
...snip...
for (var i; i < nodes.length; i++) {
}
etc...
}
]]>
</script>
Now the "less than" is being rendered as an xml character entity - which
obviously breaks the javascript.
I understood from various discussions that enclosing the function in a
CDATA block would mean it's rendered as character data - or have I
misunderstood?
This is in a component, the top of my .tml has:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

Yes, it worked for 5.1 and still works for 5.2. There are absolutely no
delays.

We've always added "-Dorg.mortbay.jetty.webapp.parentLoaderPriority=true", something doesn't work properly if we don't, but that was all done over 2 years ago. The dev environment hasn't changed, but with T5.2.0 Live class reloading no longer works.
Igor, does live class reloading work properly for you using runjettyrun and T5.2.0? I'd imagine for small sites it wouldn't be very easy to notice, but for us when we change something (component or page) there's a fairly lengthy pause the next time a page is requested. Do this a couple of times, and permgen space is quickly exhausted.
I'm hoping that the a global service reloading switch will be provided so we can turn that off and see if we can get components & pages reloading as before with T5.0 & T5.1
Thanks,
Andy.

I use Maven to run Jetty. This works inside Eclipse with the
M2Eclipse plugin and also directly from the command-line. You get to
specify which version of Jetty you want to use and JNDI also works
(just specify Jetty Plus). I've pretty much abandoned Run Jetty Run
at this point.

I'm using run-jetty-run and there is no need for any configuration. Just
install it and start your web app. The only problem is that JNDI is not
supported.

EclipseJetty is a fork of http://jettylauncher.sourceforge.net/ (Jetty
Launcher is not maintained anymore and doesn't work with recent Eclipse
versions). EclipseJetty has some magic in it, which excludes jetty and
servlet-api libs when starting Jetty.
I think RunJettyRun is also a fork of Jetty Launcher (but I'm not sure).
With RunJettyRun you have to add
"-Dorg.mortbay.jetty.webapp.parentLoaderPriority=true" to make Tapestry 5
work (see
http://wiki.apache.org/tapestry/Tapestry5HowToSetupEclipseRunJettyRun).
The main difference is that RunJettyRun comes with an included Jetty, with
EclipseJetty you have to chose an external Jetty install folder.

What's the difference between RunJettyRun and EclipseJetty?

Is this a problem of runjettyrun?
We're using http://eclipse-jetty.sourceforge.net/ (my fork of Jetty Runner)
with Eclipse Galileo and m2eclipse. Live reloading works for us with this
config.

Are you using Java 1.5? The classes are not GCed by 1.5 - with 1.6 it works

What kind of memory settings are you using? This works fine for me
(on a Mac of course), but with -Xmx600M ... and you may need to extend
permspace as well.
Long pauses sound like GC to me ...
