Hi Experts,

Could you provide the link/doc to create a Java client for the webservices(wsdl file) from NWDS?

Thanks & Regards

hi,

you can create webservice using SAP PI,

but inorder to test the webservice you can use XML SPY software,

if you want to use NWDS to trigger webservice.. go thru this blog;

Hi Sara,

There is a difference in the way NWDI generated the service interface for web services client in SP3.

Until SP3 we used tha SUN RI JAX-WS runtime. In order to deliver the WSDL location packaged with the archive we used ClassLoader.getResource(..).

SP3 uses SAP JAX-WS Runtime which extracts the WSDL Location from annotations in case of deployable client and from static variable when the clients are standalone.

However we made a distinct difference and changed the generation so deployable clients could no be instantiated with "new" and the default constructor.

It should be clarified that deplyable clients should be instantiated using JNDI lookup or injection wuth @WebServiceRef annotation.

So if you need a standalone WS client generate a standalone proxy from the NWDI and it will contain the required code for initialization.

If you are making a java ee application please use the instantiation methods advised by the jave ee specification (lookup or injection).
