Error while creating deployable proxy to comsume .Net web service

[Former Member]

Hello Experts,

Web service created in .Net has to be consumed in java.

I m creating deployable proxy project but when I try to create a proxy client through NWDS 2.09 , providing the URL of the Web service wsdl, I get following error

"Problems while generating the Proxy Definition!"

and the NWDS log shows :

!ENTRY com.sap.ide.ws.proxygenerator 4 -1 Jun 02, 2011 19:47:40.728

!MESSAGE com.sap.engine.services.webservices.jaxrpc.exceptions.ProxyGeneratorException: Proxy Generator Error. Proxy generation problem. See nested exception.

I finally used the NWDS version 7.0 to develope the proxy.

If you are consuming a web service in NWDS.....i.e. a WSDL file as a service....

you can follow below document...and check if you are not missing any step.....

Hello ,

thanks for reply,

I m following the steps given in the document but while configuring the proxy in the step 2 when I click on finish after browsing the WSDL file.. I get the above specified error.

I tried to create proxy with NWDS v 7.0 and i was successful but I want accomplish same in v 2.09...

I exported the created proxy project from version 7.0 to v 2.09 and found that the missing class is the Facet class in my webservice_lib.jar which is why i m facing the problem...

Please advise, whether I should download the newer version of the webservice_lib.jar and set in the class path before creating client proxy.. I won't create problem bcuase of exixting .jar in server after deployment.

thanks in advance
