assuming you are implementing axis by a multithreaded container
a thread from each service class is created and handed to the requesting client
then when you request a context classloader
you ask for the Thread specific CL as seen here
return Thread.currentThread().getContextClassLoader();

Subject: A tough question about axis2
To: java-dev@axis.apache.org
Dear Developers:
Sorry to trouble you.
Hello,I am a Master Student using your brilliant axis2 which makes me feel
happy since it is so flexible and robust.Now my team and I are developing a
small project by using it.But there are tough questions I still don't
understand after I've saw the axis2 quick guide& the axis2 architecture & some
posts in some forum and ur offical website.So could you please help me for the
questions as follows.
As we know,when a request comes to tomcat,tomcat will searc the
corresponded container and see whether an instance of this servlet class
exists,if so,the request will use it and don't create a new instance.OTHERWISE
,a new servlet instance will be created . So there is always only one instance
of servlet for a certain class available in the tomcat.With respect to axis2,we
know that,it is a project that should be placed under the webapps folder.So its
mechanism is the same with the the common JSP project,is not it?
The Question ,I am now wondering, is that:given that there are many clients
for a available webservice now,some class(denoted as Clazz) which provide the
api of the webserive.So when different requests from various clients come to
axis2,how does axis2 deal them?By saying that,I mean,do they clients share the
same "Clazz" instance,OR each client has a instance respectively of Clazz.It is
my puzzle!!!
In my opinion,each request has a instance,since if you don't use
context,the instance variable in Clazz cannot share values,or put it in another
way,Only using a cetain context can we share a instance variable.Say,if we use
the ConfigurationContext in a webservice class and we put a value in this
context,different clients can share it.
If you can provide me some tips or reference,better!
Thank you for taking a time to check my emails.
Hope you are happy.
Best Regards,
