[Axis2] How to share a service implementation with Axis 1.x?

[Rodrigo Ruiz <rr...@gridsystems.com>]

Hi all,

I am trying to find out if it is possible to publish a service 
implementation with both Axis 1.x and Axis 2. I need to do this for 
ensuring compatibility with the current version, as it uses RPC/encoded.

The idea is to have a single internal implementation, published as an 
RPC/encoded service with Axis 1.x, and as a Document/literal service 
with Axis 2.

I am planning to put all the service implementation classes into the 
shared/lib directory, deploy a separate webapp for each Axis version, 
and deploy the same service on both webapps.

Being still in an analysis phase, I have some technical doubts that, I 
know, will have to be addressed before deciding the final architecture.

1. Will the support of RPC/encoded be added to Axis 2? If the answer is 
yes, I would prefer to wait for its availability, depending on when it 
is planned to be added.

2. Is it possible to use both Axis versions within the same classloader? 
That is, can the same webapp have an Axis 1.x and an Axis 2 servlets 
working at the same time? Would this produce class name conflicts?

3. Is there a "known best practice" for sharing my service beans among 
both Axis versions? I am considering to generate them with XmlBeans, but 
I guess the generated classes will only understand document/literal OR 
rpc/encoded, but not both.

4. The service currently throws an Exception that inherits from 
AxisFault, and I would like to remove this dependency. It is done so, 
because we wanted to fill the fault code and details with some internal 
data (for message i18n support on the client side). Is it possible to 
control the serialization of all these fields with an Exception that 
does not inherit from AxisFault? Maybe with custom serializers?


Sorry, I know they are too many questions.

Thanks in advance,
Rodrigo Ruiz
