Dynamic innovation of WS client-JAVA

[Kanchana]

Hi,
I have a WS service which is not a Axis WS  based service but it's some java based  service exposed which has it's own soap compiler.This smiler service have deployed and run  in multiple machines.I should write a common client to invoke the service in  a vendor independent way.My Question are

1. How do i implement it as a dynamic invocation using a common client.

2.If I use dynamic client using JAX_WS how dose it provide the SEP independence with the artifact generated by wsimport tool ?

3.Do I have to use Dispatch client /Dynamic Proxy client?

I found this url following url,are there any articles which shows more elaboration?

I tried using the following approach to  invoke a dynamic web service client and I get the following error.This is a  non axis web service and client uses RPC call and and ServiceFactory

your input will be highly appreciated

Well whole idea of Web service is to have a vendor independent way of
accessing the service, for example in order to invoke a Web service what
we need is to have the WSDL.

You can generate the stub for the client, and then dynamically you can
change the EPR and invoke the service. Since all the services have the
same API one client should be able to talk to all.

You can generate the stub for the client, and then dynamically you can
change the EPR and invoke the service. Since all the services have the
same API one client should be able to talk to all.

 Question about changing the EPR dyanammically

1. You mean giving the technical user to enter the epr in a property file and handle it dynamic way in a program or is there a specific API to make it dynamic.Any samples?
I don't understand how you can make the generated stubs to invoke dynamically since generated code itself  has hard coded end point url unless you do the above.

Basically what you are saying I can use the generated stubs and make it dynamic  rather writing a Dynamic client with out generating stubs?

2.If you generate the stubs for a particular service when you change the service you will have to regenerate the Stubs again?doesn't  the dynamic invocation provides you more re-usability by creating proxies on the fly?

3.How  I can provide the user control to access which machine's service to be accessed based on the technical user  requirement?

Thanks in advance for your time
