Re: top-down service creation / OSGi

Hello, I didn't see any way to search the list at:
http://mail-archives.apache.org/mod_mbox/tuscany-user/
 
So forgive potentially redundant questions.  I have two:
 
1.) I looked at the service creation tutorial:
 
http://tuscany.apache.org/build-your-first-web-services-with-tuscany.htm
l
     I see this is a "bottom-up" approach using code annotations.  My
question is: can we start with a WSDL
     and create a service component for/with Tuscany?
 
2.) Is there a way to create a mix of service components that use
different versions of the same JAR dependencies?
     i.e. something like OSGi?
 
Thanks,
 
Chris W.

Hi,

1) Sure, you can start with a WSDL to create an SCA component.

For example, if you want to develop a Web Service with Tuscany, you can do 
the following:

a. Develop a WSDL
b. Run JAX-WS wsimport tools to generated the Service Endpoint Interface 
(SEI) and related JAXB classes
c. Write a Java component that implements the SEI
d. Configure the component service with Web Service binding (binding.ws)

To consume a Web Service:

c. Write a Java component that consumes the SEI by defining an SCA reference
d. Configure the component reference with Web Service binding (binding.ws)

To add a BPEL process:
a. Develop a WSDL and BPEL process
b. Create an SCA component with implementation.bpel
c. For partnerLinks, you can use Java components that consume or provide the 
services using the JAX-WS SEI generated from the WSDL

2) Tuscany 2.x stream (trunk) has full OSGi integration including the 
runtime enablement and a prototype of Distributed OSGi.

Thanks,
Raymond

hi chris,
i am just getting started too, but you should look at felix or equinox for
the mix-n-match aspects via osgi. for the top down dev, i've been going the
XSD/JAXB2/Spring route and it seems to be working.

Can anybody help me with this question? Especially the question
regarding top-down service creation.
 
Thanks,
