RE: WSIF and complex type

Hi. I tried to use WSIF with complex types a few weeks ago, and decided
that if you want to consume web services dynamically with complex types
you're better off starting from scratch. What I mean is that you can use
Apache Axis ( or SOAP ) library to create your SOAPMessage and populate
it with whatever you want. 

The steps that I take are the following;

*	Read in the WSDL descriptor
*	Get the SOAP binding and list all the operations associated with
the appropriate PortType
*	Pick an operation
*	Build input according to the WSDL descriptor
*	Create the request SOAPMessage and invoke the web service
*	Process the response SOAPMessage that comes back ( if you're
lucky, with no errors !! :-)). What to expect is again based on the WSDL
file

 

It's quite a complex process if you want to be able to handle any web
service. I reckon the best approach would be to create the Body of the
SOAPMessage as xml, and just add it to the SOAPBodyElement. Having said
that, I haven't done that for a variety of reasons ( which I am
regretting a wee bit now ). 

Basically if you follow your solution 1, you should be able to tackle
this.

Subject: WSIF and complex type

 

Hello everybody,

 

I try to write a java GUI application which can invoke any Web Service
(SOAP first).

Mecanism like http://www.strikeiron.com/analyzer/OnlineAnalyzer.aspx

 

I can parse and present graphically WSDL element on my java GUI, but, my
problem is the COMPLEX TYPE !!!!

How can I manage complex type with WSIF?

 

So I have many solutions:

 

1 - Write my own SOAP client (like this :
http://www2.sys-con.com/ITSG/virtualcd/WebServices/archives/0310/behera/
index.htm)

 

2 - Use JAX-RPC to use DII interface, generate in-fly the stub and use
java.lang.Reflection to use these stubs.

 

3 - Use XSUL2 to use WSIF interface to send directly XML element for
input, output and fault parameters.

 

But, it seems that

1 - It is difficult to write its own SOAP client because of many
different encoding

2 - I don't really know how to do this

3 - I try to use XSUL2 without success and the XSUL mailing list doesn't
return me any response of my problem (I have a xsul.wsif.WSIFException)

Details: no provider could be found for WSDL port <n1:port
name="HelloIFPort" binding="tns:HelloIFBinding"
xmlns:n1="http://schemas.xmlsoap.org/wsdl/">

      <soap:address
location="http://dev2k15.dev.orsyp.com:8080/hello-dme/hello"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" /></n1:port>

 

So, I want to know if somebody resolves this issue of complex type with
WSIF or with something else....

 

Any help or sample code will be appreciated.

 

Thanks a lot.

 

Delphine.
