Yes, Alek is correct. You have to do some additional work to make use
of WSIF dynamic invocation on complex types, but it can be done.
My company has been using WSIF as infrastructure for a user-interface
provider for web services for several years, using dynamic invocation
based on the WSDL and the schemas it references. A wide variety of
complex types (but not all) are handled. WSIF is a small but significant
piece of a larger system, which gathers the input to the web services,
invokes the services, presents the output, and allows the data from the
outputs to be used to construct inputs to other services. The
automatically-generated user interfaces can be delivered on the desktop
or various mobile devices, and customized and beautified with additional
metadata (beyond the schemas) to set up the user-driven chaining of the
services and present the WS inputs and outputs in a way more suitable
for end users.

the issues for discussion is "support" - if one expects automatic
handling of
all of XML schemas types in WSIF that is not what WSIF does but it does
help with mapping Java data (or just XML possibly that follows XS
- that is dynamic case) and sending XML to a service identified by WSDL.
in my experience dynamic case is typically encountered in two situations:
1. some kind of user interface: it needs to parse WSDL and present input
to user
then it can use WSIF to send that input to that service
2. workflows or other systems that need to invoke services described in WSDL
but those systems do not generate input they just do its processing and
they are less dynamic (and can handle less of varied inputs) more
processing they do.

WSIF does not support complex types in dynamic invocation.
Try and see XSUL, if works.
Please let me know if you get working with XSUL.

Subject: Need help invoking complex web services
Hi,
We're trying to create a Java application capable of
consuming any web service dynamically given only the WSDL.
The only problem is that we can't figure out how to invoke a
service that takes a complex type as a parameter without
first generating code. Is it possible to use WSIF to do such
an invocation without generating code, and if so, could
someone please send us some hint on how to do so?
thanks,
Tim
