Hi Periklis,
I had a lot of similar classpath issues with Axis 2 1.2 recently and
managed to sort them out. I tried all the tricks like exploding the
.aar file, but in the end none of it was necessary.
My .aar file is the same structure as yours - and I'm using the
following to load my log4j.properties using the service classloader:
ServiceSkeleton.class.getClassLoader().getResourceAsStream(
"log4j.properties");
This picks up the class file from the root of my .aar file, fine.
The main thing that was causing me problems was that some of the classes
I was trying to load (e.g. Log4j.jar in particular) were also in jars or
the classes area of the main axis2/WEB-INF area as well as being in the
.aar files. Axis 2 was picking them up before looking in my .aar files
and then loading them with a different classloader - hence my service
wouldn't load them, but it would still get Class Def Not Found errors.
Simply clearing these jars out of the axis2/WEB-INF/lib folder fixed
this all up for me.
cheers,
Ants.

Hi again,
after couple of different packaging experiments and still not working
solution, i stepped in a weird situation.
My Service now has the following structure:
myservice.aar
-- META-INF
---- service.xml
-- lib
---- lib1.jar
---- lib2.jar
---- lib3.jar
---- lib4.jar
-- com
---- ....my classes here incl. the service impl class
The weird situation now is, that if try to load a class included in com
inside my service implementation class, with following code, i get still
a ClassNotFoundException.
ClassLoader loader = getClass().getClassLoader();
Class myclass = Class.forName('classname', true, loader);
or even with
MessageContext msgCtx = MessageContext.getCurrentMessageContext();
AxisService serviceHandler = msgCtx.getAxisService();
ClassLoader serviceLoader = serviceHandler.getClassLoader();
//Class serviceClass = serviceLoader.loadClass(service);
Class serviceClass = Class.forName(service, true, serviceLoader);
MyClass srv = (MyClass) serviceClass.newInstance();
still ClassNotFoundException.
If i import the class and instatiate it, then everything works fine.
The Class i am trying to load with the Classloader doesn't use any class
from the jars included in the lib directory.
I tried also all the workarounds above with an unpacked aar.
Anybody an idea?

Hi,
i am currently working on a service, that is deployed in a service
archive, as described in the documentation. This service needs access on
a library which is located under WEB-INF/lib, due to further usage of
this library out of my service.
I am using axis 1.3 deployed as a war on a Tomcat 5.5.12.
The jar structure of mylib.jar is:
mylib.jar
-- META-INF
---- MANIFEST.MF
-- lib
--- ...couple of libs here
-- com
---- ...classes in package hierarchy
My service archive myservice.aar is located in the WEB-INF/services and
i have hotupdate in my axis2.xml configuration enabled.
The code i am trying to access classes from the jar file in my service
implementation class is following:
MessageContext msgCtx = MessageContext.getCurrentMessageContext();
AxisService serviceHandler = msgCtx.getAxisService();
ClassLoader serviceLoader = serviceHandler.getClassLoader();
//Class serviceClass = serviceLoader.loadClass(service);
Class serviceClass = Class.forName(service, true, serviceLoader);
MyClass srv = (MyClass) serviceClass.newInstance();
The deployment of the service is working fine, but when i call some
function of my service implementation class that itselfs needs an
instance of the mylib.jar i get a ClassNotFoundException.
I have tried also the setOperationContext way, but as i read in the
mailing list, this way is not thread safe.
Has anybody an idea?
Thanks in advance.
