Unable to create an instance by using Adaptive webservice in Webdynpro App

[Former Member]

Hi,

I am trying to develop a WebDynpro application using Adaptive Webservice model. I have created a model using WSDL in my application in order to get the Sales order data from the Backend (R/3).

The problem is that after doing context and model mapping in the view and custome controller I am not able to create an instance for the Request parameter.

Code in custome controller:

Request_ZFmServDocflow Request = new Request_ZFmServDocflow();

wdContext.nodeRequest_ZFmServDocflow().bind(Request);

Request.setZFmServDocflow(new ZFmServDocflow());

In the above code for "Request_ZFmServDocflow" I am not able to create an instance, Its saying <b>The Constructor "Request_ZFmServDocflow" is not defined </b>(Its expecting some parameter).

I have followed the Email Webservice application in SDN But couldn't understand the problem. Need your expertise in this application. Can anybody explain how to develop an application using WSDL in WebDynpro's. Also if any links that could explain the entire scenario.

Hi Kalyan,

your code is very fine, there are some jars missing.

add theses jars in java build path of your project

1.xmlparserAPIs.jar

2.XmlWrapper.jar

3.webservice.jar

4.jaxrpc-api.jar

5.jaxm.jar

hope this will solve your problem.

Hi venkat,

Even after including the jar files that you have mentioned I am getting the same error.

May be it is all due to proxy setting. Can you explain me what should i give in the proxy address and port Input fields.

The settings are at

Windows> Preferences> Workbench (left pane)--> Proxy settings

This is all my assumption that the error is due to proxy settings. It can be any other reason. Can there be any other reasons for this kind of error ?

thanks,

Hi kalyan,

Request expects the Instance of ur web service model .Create the instance of ur model & pass that to request.Suppose u have the web service model named SuppliesModel,as i have written in code.

e.g.

SuppliesModel suppliesModel = new SuppliesModel();

FindAllSupplies findSupplies =new FindAllSupplies(suppliesModel);

Request_FindAllSupplies reqModel =new Request_FindAllSupplies(suppliesModel);

findSupplies.setCountry(country);

wdContext.nodeRequest_FindAllSupplies().bind(reqModel);

then execute.

Hi kalyan,

Where is ur webservice hosted??Check in the webservicenavigator whether its working fine on that system.Check the destinations also in Visual Administrator.
