Hi,
I am a Student WO Developer and I am trying to make a simple webService, =
not so simple because I would like my webService Client to receive an =
Object from my webService. It is exactly similar to the Calculator =
Example from the WebObjects Documentation, except that the Object that =
my webService returns is not a common Object, it is a Movie Object.=20
I think that everything would still be simple if this Movie Object was =
defined in EOModeler, but it is not.. so there is no .eomodel that (i =
guess) can help WO5.2 to build the Serializer and the Deserializer for =
my Movie.=20
I don't understand exactly how everything works under WebObjects. =
(That's the goal of WebObjects ! Abstraction)
However, there is no problem for the generation of the webService (wsdl =
file, etc), I just get an error at runtime telling me that there no =
EOClassDecription for my Movie Object.=20
So I tried to write the serializer/deserializer myself (Actually, with =
the WSDL2Java program in the Axis.jar, I can get a new Movie.java file =
with methods for (de)serialization )
But after that, I think I still have to register my Movie Object to the =
webService. That's where I am now. I don't know what to do: do I have to =
use some low-level methods from Axis, jaxrpc, ??? Are there WO tools for =
such things? Can I use de WOWebService and WOWebServiceClient instance =
that I can get from the wsdl file ( constructor : =
WOWebService(javax.xml.namespace.QName aQName, URL aUrl) ) and then use =
the register(....) method?
Do you have any idea, hints, examples to help me ? I'm not the first one =
using webService with WO, so I am pretty confident there's a beautifull =
tool somewhere that I didn't see, which will help me. :-)
In mailing-lists, people always refer to the Amazon example, in the WO =
Documentation. I can't find it ! Do you?
Thanks a lot in advance,
Denis
