Class loading problem

Hi All,
  I have a class loading problem that is only happening when running SM in
standalone mode. When SM is hosted inside JBoss, there is no problem.
The situation is like this:
I have component with its Bootstrap implementation class extending a class
in an installed shared library. The component is referencing the shared
library in its deployment descriptor. I install the shared library first
then install the component, NoClassDefFoundError exception is thrown upon
installation.

Here is the trace:

INFO - AutoDeploymentService$2.run(504) | Directory: install: Archive
changed: processing csi-0.1.jar ...
ERROR - InstallationService.initializeInstaller(528) | Deployment of
Component failed

Any thoughts?

Subject: Re: Class loading problem

If the class is extended by the component, you should be able to use
    getClass().getClassLoader()
which should return the component class loader.
Alternatively,
    Thread.currentThread().getContextClassLoader()
should return the same as the previous call.

Cheers,
Guillaume Nodet

Re: Class loading problem

Posted by Guillaume Nodet <gn...@gmail.com>.
If the class is extended by the component, you should be able to use
    getClass().getClassLoader()
which should return the component class loader.
Alternatively,
    Thread.currentThread().getContextClassLoader()
should return the same as the previous call.

Cheers,
Guillaume Nodet

Re: Class loading problem

Posted by Hossam Karim <hr...@gmail.com>.
Nice work.
I create a custom ApplicationContext in the 'init' lifecycle method.
Will the fix still help? Should I pull the source now?

Re: Class loading problem

Posted by Guillaume Nodet <gn...@gmail.com>.
I have just fixed an issue wrt to classloading.
The current thread context classloader was not set to the component
class loader when the component was created.
Did you initialize your spring stuff at creation time from the
component constructor ?
If yes, you may want to give a try to the latest svn head...

Cheers,
Guillaume Nodet

RE: Class loading problem

Posted by Hossam Karim <hr...@gmail.com>.
Ok, keeping it simple, can you tell me which class loader I can use to
explicitly load a class on the component class path from code on the
container class path?
My case is simple; I have a library of helper classes over the JBI API that
resides in the SM lib directory. One of these classes
(AbstractComponentAdapter) is always extended by the component class. When
SM invokes the 'init' method, ' AbstractComponentAdapter' tries to load some
Spring beans from an XML file that comes with the installed artifact.
Forgetting about Spring, I just need to be sure that I can load any class on
the component's class path from the shared code. The ComponentContext class
loader should be the one, but still not working.

Thanks for your patience,
 Hossam

You may try the following things:
  * set the thread classloader to the classloader of the component
(though this should have already been done by ServiceMix)
  * change the classloader so that it delegates to the component
before trying the parent classloader: this will ensure spring is
loaded from the component class loader (you have to put it in the
component class path)
  * use xbean as done inside the servicemix-common / XbeanDeployer (it
works)

It seems really strange as all ServiceMix components use spring to
load service unit as an xbean / spring configuration file.
I think that the spring application context may have some property to
override the classloader to use: maybe you have to set it explicitely
to your thread context classloader.

Cheers,
Guillaume Nodet

Re: Class loading problem

Posted by Guillaume Nodet <gn...@gmail.com>.
You may try the following things:
  * set the thread classloader to the classloader of the component
(though this should have already been done by ServiceMix)
  * change the classloader so that it delegates to the component
before trying the parent classloader: this will ensure spring is
loaded from the component class loader (you have to put it in the
component class path)
  * use xbean as done inside the servicemix-common / XbeanDeployer (it works)

It seems really strange as all ServiceMix components use spring to
load service unit as an xbean / spring configuration file.
I think that the spring application context may have some property to
override the classloader to use: maybe you have to set it explicitely
to your thread context classloader.

Cheers,
Guillaume Nodet

RE: Class loading problem

Posted by Hossam Karim <hr...@gmail.com>.
Well, it is not working, Spring can't find the classes although they are in
the components class path, and the loading takes place in the 'init' method

You should include the jars where the beans are in the component classpath.
If you want to do that at bootstrap time, you need to include them in
the bootstrap classloader that you define in your jbi descriptor. 
This classloader has servicemix container classloader as a parent and
includes all the jars listed in the bootstrap classloader defined in
the jbi descriptor.
Spring should use the thread context class loader to load beans, so it
should work even if spring is in the parent class loader (the
container one).

Re: Class loading problem

Posted by Guillaume Nodet <gn...@gmail.com>.
You should include the jars where the beans are in the component classpath.
If you want to do that at bootstrap time, you need to include them in
the bootstrap classloader that you define in your jbi descriptor. 
This classloader has servicemix container classloader as a parent and
includes all the jars listed in the bootstrap classloader defined in
the jbi descriptor.
Spring should use the thread context class loader to load beans, so it
should work even if spring is in the parent class loader (the
container one).

Cheers,
Guillaume Nodet

RE: Class loading problem

Posted by Hossam Karim <hr...@gmail.com>.
So if I am loading some beans XML source that comes with the component
installation artifact, is it expected that Spring can normally load the
beans, or should a special procedure be taken according to your
understanding of SM class loading mechanism?

ServiceMix has the spring jars inside its classpath, so it is also
available to the components.  But if you want your component to be
container independant, you have to include it.

RE: Class loading problem

Posted by Hossam Karim <hr...@gmail.com>.
I guess you mean the component class loader. Do I really need to do that,
add the library to the runtime and deploy it again with the component
installation artifact? This means also that Spring libraries have to be in
the component class path as well in order to create the beans.

Did you put your jar in the bootstrap class loader (in your jbi descriptor)
?
Not only in the runtime class loader ?

BTW, I set the bean reader to use the component's class loader, but still
Spring can't find the class.

Re: Class loading problem

Posted by Hossam Karim <hr...@gmail.com>.
Thanks Guillaume and congratulations,

OK, then. I am not going to argue about why this is not the case in the
JBoss environment since it is not supported.
Now I moved the shared code to the lib directory, so the Bootstrap is
initialized. The component implementation base class is also in this shared
code, I am trying to load some beans from the shared code, and the bean
class comes with the component installation artifact, so I am asking the JBI
class loader to load resources available only to the component class loader
which is also NOT JBI complaint, right?
Do you suggest a solution for this?

AFAIK, this is not JBI compliant.
See section 7.3 of the jbi spec.
