when WSDL is not static ..
Hi All
I got use case where i don\t have a static wsdl but want a DII client
invocation.I\m planing to use Axis2 .Earlier i used for static wsdl using
proxy generators .But this time I can\t use proxies.In further I get a WSDL
file that defines message based SOAP calls. The payload message is defined
in XML Schema. It can contain any number of complex types.The Schema should
be displayed in the "Creater"(Creater where we make the xml definition for
particular web flow ) and the user should be able to link variables/items in
Spikeflow(www.nspike.com/) to elements/attributes in the schema. Then in
running our runtime should be able to create correct SOAP requests to send
and be able to parse SOAP responses.
Normally we would do this by generating java objects with JAXB that
maps to the Schema. But we can't do the JAXB and compilation step,
since the WSDL and Schema changes.
Really appreciate if any one can shoot any ideas on this
Thanks a lot
Kanchana

I thought Kanchana was talking about a WSDL/Schema, which keeps on changing.
So in fact, Kanchana is talking about generating clients for different WSDLs
(not a changing WSDL)?

I think what is trying to be acheived here is what we do in WSAS with
our dynamically generated Javascript test clients.
Obviously its possible to do this - you need code that navigates the
schema and helps you create XML from that. There is code like this in
Eclipse and SOAPUI. The real problem Kanchana is going to have is how
to set the parameters into this code. In WSAS we do this with a human
:) In other words we dynamically generate a web page, and its up to
the human to look at the web page and decide what data goes in which
field.

A WSDL is a contract, and changing this often is not the correct thing to
do. Changing the service contract often goes against the fundamentals of the
SOA paradigm.
Someone may be able to suggest a better solution if you could explain the
problem you are trying to solve (not the way you intend to solve it)
