Ahem... every six months someone asks this ;)
The easiest way is to get the type from the WSDL and register the
ElementSerializer / ElementDeserializer to it. This isn't very hard to
do, we have to jump through slightly nastier hoops for my project
(because we want to handle cases where there's already a mapping and
it's a little painful) but the above works, you end up with a DOM Node
corresponding to the SOAP body of the message as a return and the call
consumes a Node containing the request body.
This is used (mostly) with success in our workflow project, means users
can drag WSDL in and get each operation with at least a vague attempt to
be sensible around complex types (we don't control the services)
Code is here
http://cvs.sourceforge.net/viewcvs.py/taverna/taverna1.0/src/org/embl/ebi/escience/scuflworkers/wsdl/WSDLInvocationTask.java?rev=1.21&view=markup
(runs the task) and
http://cvs.sourceforge.net/viewcvs.py/taverna/taverna1.0/src/org/embl/ebi/escience/scuflworkers/wsdl/WSDLBasedProcessor.java?rev=1.36&view=markup
(sets up the mappings) - apologies for the complexity, those hoops I
mentioned earlier? They're on fire, and probably covered in acid
dripping razor blades; you can probably get away with something a bit
simpler.

Hi,
im going to use axis for consuming webservices. i would like to invoke
services completly dynamic. at the moment i cant find a simple way to do
this.
my problem: i want to use any wsdl and make dynamic calls while runtime.
but: i cant find a easy way to use webservices with complex types. i
only know the beanserializer/beandeserializer for using complex types
and this means i must create javacode and compile it.
im not happy with this situation cause every client maschine must have
jsdk and compile code! isnt there an easier way?
im not sure about the axis sysem architecture but wouldnt it be possible
to write a serializer/deserializer which output is not a filled bean
but some sort of data in a map for example. with the data contained in a
map (or an dom tree maybe) i could simple access it while runtime.
anyone an ! idea? maybe someone wrote a solution for this problem? if
there's a way to solve this problem without serializer it would be
alright for me ;-)
thx in advance
