NoSuchMethod Exception

[Former Member]

Hi everybody!

I'm trying to access to a Web Service Model. I've created the model using a local WSDL, imported it, and binded to the controller using the service controller template. But when I execute muy app I get a NoSuchMethod exception:

//This is the method which fails

XIModelWS model = new XIModelWS();

And here is the exception:

java.lang.NoSuchMethodError: com.sap.engine.services.webservices.espbase.client.dynamic.DOperation.getOutputParameters()[Lcom/sap/engine/services/webservices/espbase/client/dynamic/DParameter;

Thanks in advance.

Hi,

Before Integrating Webservice With Webdynpro,add the Following Code in the Execute Method,

wdContext.current<BapiNode>Element().modelObject()._setUser(<Username>);

wdContext.current<BapiNode>Element().modelObject()._setPassword(<Password>);

Regards,

Nandha.

Hi Nandha,

These methods do not exist... maybe with _setAttributte?

Thank you!

Hi Eneko,

Ur webservice is not deployed properly on ur server .have u made any changes in webservice after creating the model??generally this problem comes only when u make any changes in ur webservice after creating the model in webdynpro.

If u have added any new attribute or method,u have to reimport the model.

Hi Sumit,

Umm... I'll have a look to the Webservice, I think anybody has changed it.. but who knows.

Thank you!
