[jetty-users] Jetty 7 and knopflerfish 3
|
I succesfully installed and run an instance of Jetty 7 (latest
version, 7.1.6) inside Knopflerfish 3.0. I got working servlets, JSPs
and continuations. Did not test tag libraries.
My goal was to install war archives that could have access to the
BundleContext so that servlets could interact with other services
installed inside the OSGi framework.
There has been a couple of confusing moments, especially when I found
that the jetty.xml in the "etc" directory (not the etc inside the
jetty.osgi.boot bundle), installs either a WebAppProvider (that - as in
the jetty standalone configuration - monitors the contexts directory for
xml files and the webapps directory for wars) and also an
OSGIAppProvider that installs web applications only via contexts (and
monitors the same directories as the WebAppProvider). Seeing that a
WebAppProvider and an OSGiAppProvider seems similar, I'd like to know if
a WebAppProvider should not be used inside an OSGi installation and if
it could cause problems (i.e. classloading problems).
But anyway, the only way I found I could install a war that could have
access to its bundlecontext is only by installing and *starting* a war
file like it was a bundle (i.e. with a META-INF/MANIFEST.MF correctly
set up). I don't know if the OSGiAppProvider can insert the
bundlecontext property inside the servlet contexts, by just looking at
the source code it doesn't seems to me. The wiki page
(http://wiki.eclipse.org/Jetty/Feature/Jetty_OSGi) doesn't clearly
states how this feature can be enable and used.
The only problems I encountered were using the test.war that comes with
the jetty binary distribution.
Loading it from the webapp directory using the AppDeployer causes the
following errors:
- TransparentProxy fails to be installed as it generates a
NoClassDefFoundError for javax.net.ssl.TrustManager (i had the framework
bootdelegating * and put javax.net and javax.net.ssl into exported
system packages). I could not find the cause for this exception.
- TestFilter causes a NoClassDefFoundError on init for
org/eclipse/jetty/util/log/Log
I should note that test.war contains jetty jars inside its WEB-INF/lib
directory that I removed before deploying it into the webapp directory.
There is also a strange ClassNotFoundException for
org.eclipse.jetty.jsp.JettyLog. I traced the source of the problem in
the WebXmlProcessor class inside org.eclipse.jetty.webapp package, but
it seems that the JettyLog class isn't bundled anywhere (it is in the
jetty-jsp-2.1 module inside the jetty source distribution but that
module seems like it isn't packaged as a bundle). Looking at the code
for that class there's also a dependency from
com.sun.org.apache.commons.logging package so probably that would cause
some issues.
That's all; attached you can find a working init.xargs for knopflerfish;
your path may (of course) vary.
