question about supporting complex data type

["Agarwal, Naresh" <na...@informatica.com>]

Hi

If we use some complex datatype (as parameter/return value) in one of the functions of a Web Service, which is deployed using AXIS, then the Web Service client would need the following apart from WSDL file:

1) class file for complex datatype
2) class file for serializer and deserializer for the complex data type

Where would Web Service clients get this from? 
Do these reside at the same place as WSDL? 
Does UDDI have any information about the location of these?

thanks,

regards,
Naresh Agarwal

It's up to the client developer to figure out how to process the complex
types. As an Axis service developer, you might consider providing class
files for Java clients (a JavaBean to represent the complex type, the
serializer routine, and maybe any exception routines), although I doubt that
you would provide comparable files for other languages (e.g., VB, C#, etc).

If you want to provide the class files, you could register them in UDDI,
although there's no standard convention for doing so. I'd create a taxonomy
tModel to represent Java class files. Then create a tModel to represent each
class file and categorize them as Java class files. (The keyValue attribute
would indicate what type of class file you've supplied.) Have the
overviewURL of each tModel point to the .jar file, and add
tModelInstanceDetails elements in the bindingTemplate to point to the class
file tModels.
