Pls help (very urgent)... hit exception on runtime...

Question

hi,
hope my help can come in time...
its pretty urgent as my final presentation is on this coming friday(singapore time)...
i had coded a class where i can connect to the public UDDI. now i want to get the WSDL document location. but i could not get what i want. then, i used the Service class from the javax.xml.rpc where it has the getWSDLDocumentLocation() function.
but when i implement it in my class, when i compile, it does not have any errors, but when i run it, it hit the following error:

Answer 1

Eric ,
You are trying to cast a javax.xml.registry.infomodel.Service to javax.xml.rpc.Service. This is not right
This is causing the problem.
There is an article on how to use the different Java Web services developer pack technologies using the example of the employee portal at
http://developer.java.sun.com/developer/technicalArticles/WebServices/WSPack2/index.html
That may give you an idea on how to go about doing it.
Thanks,
Bhakti
