Hi Martin,

yes exactly and that's the reason we switched over to REST services and particularly for mobile devices. Even though ksoap2 on Android seems to be fairly efficient it's still a bit
heavier that the REST/HTTP mechanisms.

Regarding the publishing of the REST service, as you pointed out there's not a standard method to publish them - some ideas I saw generate documents that describe the directory hierarchy for the server side along with the URL specifications on how to reach the various resources. I use Ajax for building clients for these services. But I can certainly work with you
on coming up with may be a more general architecture.

In any case, thanks for the feedback and I will let you know about this once I give it a bit
more thought. I appreciate the information and help Martin.

not yet here is their doc

Please note that SOAP introduces some significant overhead for web services that may be problematic for mobile devices. If you have full control over the client and the server, a REST based architecture may be more adequate.

maybe you can create a testcase and we can come up with an architecture to
1)publish the REST service
2)create a Stub client which will consume the REST message

did you have anything specific in mind?

Martin

Hi Martin,

apologies for re-posting this one - do you have an idea on whether the segment you sent below
can handle REST-annotated WSDL files?

Thanks

    Hi Martin,

    isn't this parsing a SOAP WSDL file using the ksoap2 libs? Can it
    handle documents that describe
    REST as well? I guess it should but i am not sure. I will need to
    look into a bit more carefully.

    I appreciate the feedback
