Dynamic Invocation with complex types

[Miguel Alves <mi...@wedoconsulting.com>]

Hi,
 
I'am trying create a service that invoke any Webservice without knowing
that input/output types. The examples for dynamic invocation only work
with simple types, if I mention any complex type I receive the fowlloing
error
org.xml.sax.SAXException: Deserializing parameter 'return': could not
find deserializer for type {urn:GoogleSearch}GoogleSearchResult

In this case the GoogleSearch type. I know that I could use WSDL2Java to
generate the interfaces and so on...however my problem is that this
should work for any webservice so I can't write any code before invoking
a new service. 

I also tried XSUL, http://www.extreme.indiana.edu/xgws/xsul/ WSIF
implementation and it works fine showing the results without any problem

I guess I can solve this problem by writing a generic deserialization
class, that for example, put the return object in a DOM object. Does
anyone wrote something similiar ?

 

Thanks in Advance

Miguel

hi Miguel,

yes that should work and i think somebody worked on something like that 
and posted about it in axis-dev.

HTH,
