Bootdelegation and Java agent (AspectJ)
Hi all
One of the JOnAS users has an issue with bootdelegation and an AspectJ
Java agent.
All the details are here: http://jira.ow2.org/browse/JONAS-293
In short, we start JOnAS with -javaagent:<path-to>/weaver-and-aspects.jar
We also changed the bootdelegation package list to include
"org.aspectj.*" and the aspect class packages ("jlp.*").
So I expect the classes from the agent to be available from any bundle
on the system.
And when the aspectized class is instanciated, we have this error:
http://jonas.pastebin.com/ni8rcpvx (ClassNotFoundException:
org.aspectj.runtime.reflect.Factory)
I tried the 3 different policies for bootdelegation
(org.osgi.frameword.bundle.parent=app/boot/ext) and there is no changes
with any of them.
Any ideas ?
--G
PS: It works with JOnAS 5.1.5, that means with a Felix 1.8.1.

Looks like the move to Felix 3.0.6 will not be harmless :)
Anyway, thank you for your complete description, that will help.
I suspect that all theses XML classes may be required by the aspects
themselves, usually JOnAS do not require so much ugly adaptations to
start :)
We'll definitely move forward to Felix 3.0.6 and Gogo in the newt few weeks.
Thanks again

Re: Bootdelegation and Java agent (AspectJ)
Posted by "Richard S. Hall" <he...@ungoverned.org>.
Guillaume,
Ok, that reproduced the issue.
I updated your felix-launcher.jar to use Felix framework 3.0.6 since
we've made changes to implicit boot delegation, so it makes more sense
to work from 3.0.6 as a starting point.
I started getting errors for jlp.* classes. I added the jlp.* class to
boot delegation, but this wasn't sufficient because for R4.2 the default
class loader used for boot delegation has changed from the framework
class loader (which was framework implementation specific) to the boot
class loader. So, I also had the add "org.osgi.framework.bundle.parent
app" to your gateway.properties to configure the framework to use the
application class loader for boot delegation (I just guessed that this
would be the correct class loader).
That got me past the jlp.* errors, but then I got errors because the
org.apache.xerces.jaxp.SAXParserFactoryImpl provider could not be found.
As a guess, I added this to the boot delegation property too, which got
the server starting.
However, this still didn't solve the original issue, so I also added
org.aspectj.* to the boot delegation property. This led me to another
error, where the org.apache.xpath.jaxp.XPathFactoryImpl provider could
not be found, so I added that to the boot delegation property too.
This got the admin console loading, but when I logged in I got an error
because the org.apache.xalan.processor.TransformerFactoryImpl could not
be found, so I added that to the boot delegation property.
Now everything appears to be working, since I was able to access the
admin console and login. I'm not sure if you intended to get all of this
stuff working via boot delegation or not. If not maybe this at least
gives you enough hints about where to go next.
I'd definitely recommend moving to Felix framework 3.0.6 and to Gogo! :-)

Sorry for the delay Richard
Can you try with export JAVA_OPTS=... instead of exporting JONAS_OPTS
(my latest try was with JAVA_OPTS and there was the failure) ?
Make sure that the -javaagent parameter was really used (ps aux | grep
weaver)
It's possible that you may need some more PermGenSpace to run theses
aspects:
export JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=256m"

Re: Bootdelegation and Java agent (AspectJ)
Posted by Guillaume Sauthier <Gu...@objectweb.org>.
Yeah, the Exception is not thrown by the Felix framework, this is normal
because the searched class is not in the webapp.
I was expecting the framework to actually find something.
The problem is not the Exception, it's more why the framework didn't
find the libs of the agent.
To reproduce (I'm using JDK6):
1. Download JOnAS 5.2M3
(http://wiki.jonas.ow2.org/xwiki/bin/view/Main/Downloads)
2. Unzip
3. export JONAS_ROOT=<path-where-you-unziped-jonas>
4. export
JONAS_OPTS="-javaagent:<path-where-you-placed>/myaspectjweaver.jar"
(this jar is attached to the JOnAS Bug)
5. jonas start -clean -tui (Add "-debug -p 4142" if you want to launch
in debug mode)
6. Goto http://localhost:9000/jonasAdmin (the application server start
the webcontainer + the webapp)
7. Try to login (jonas/jonas)
8. You should see a stack trace (in both the webapp and the console)
Hope this helps
