Hi
Thank you for reading my post
Can you please explain following snippet for me?
<reference name="StockQuoteReference1">
<interface.wsdl
interface="http://www.stockquote.org/StockQuoteService#wsdl.interface(StockQuote)"/>
<binding.ws
wsdlElement="http://www.stockquote.org/StockQuoteService#wsdl.service(StockQuoteService)"
wsdli:wsdlLocation="http://www.stockquote.org/StockQuoteService
http://www.stockquote.org/StockQuoteService.wsdl"; />
</reference>
Imagine that i have a java class named Calculate, it has one method
which takes two numbers and return an integer as result. something like :
@WebService()
public class Calculate {
/**
* Web service operation
*/
@WebMethod
public int addThem(@WebParam(name = "a")
int a, @WebParam(name = "b")
int b) {
// TODO write your implementation code here:
return a+b;
}
}
URL to wsdl of this web service is like:
http://localhost:8080/sample/CalculateService?wsdl
Now how the above code snippet which is an SCA code snippet should
change to use my web service and its addThem method?
Thanks
Hi,
If I understand correctly you're trying to use an SCA reference with an
SCA Web Service binding to talk to a CalculateService Web service, for
which you already have a WSDL?
If this is your scenario then it's pretty simple.
You simply need to change the SCA reference to name the WSDL <portType>
and <service> (or <port>) representing the CalculateService in the WSDL
returned at http://localhost:8080/sample/CalculateService?wsdl.
It's probably best to have a local copy of the CalculateService WSDL
instead of relying on http://localhost:8080/sample/CalculateService?wsdl
to be online all the time, so I'd recommend to save it to
CalculateService.wsdl, store that WSDL locally with your other SCA
artifacts, then change your SCA <reference> like this:
<composite ...>
<component name="SampleComponent">
<reference name="CalculateReference">
<interface.wsdl
interface="http://calculate-namespace#wsdl.interface(Calculate)"/>
<binding.ws
wsdlElement="http://calculate-namespace#wsdl.service(CalculateService)"/>
</reference>
... other configuration of your component
</component>
</composite>
A few comments:
- An SCA reference usually lives inside a component (representing the
code that's going to talk to the reference), inside an SCA composite. I
just added them here to put the <reference/> in context.
- I have to guess what's in your WSDL, so in my example
http://calculate-namespace would be the namespace of your WSDL definition
- Calculate would be the name of your WSDL <portType/>
- CalculateService would be the name of your WSDL <service/>
- I recommend to avoid using wsdlLocation in general as I doubt that
your application will always run on localhost:8080 :) and when you
install it somewhere else you probably don't want to go back to your SCA
reference and change that location. What we usually do instead is we
place a local copy of the WSDL file in the client application, and the
Tuscany runtime will automatically find it for you.
Hope this helps.
