Webservice controller code.

[Former Member]

I have successfully imported the webservice model using url into my webdynpro application.Its a global weather webservice where we have to set the city and country name and execute the webservice to get the weather details as a string in one of the model attributes that is getweatherresult.

The model structure mapped on my view is as follows:

Request_Getweather

- Getweather

-> countryname

-> Cityname

-Response

->Getweatherresponse

->Getweatherresult

The whole model structure is as follows:

Webmodel

-Getweather

-Getweatherresponse

-Request_Getweather

-Response_GetWeather

I want to display the weather in chicago on my view so how do I write the coding for this on my view controller .

Hi Anzar,

To get the output from a WebService model:

1. Create a method in the controller (ExecuteWebService)

2. Create the instance of the Model created under the "Models" section of the WD project

3. Bind the object created.

4. Create an Instance of the Request node

5. Bind the object to the Request Node.

6. Set the Input parameters to the Request Node.

7. Execute the WebService

8. Get the output.

Example:

<modelName> <Object> = new <modelName>();

wdContext.nodeRequest<NodeName>().bind(new Request_<NodeName>(<Object>));

wdContext.currentRequest<NodeName>().modelObject().set<InputParameters>(<Attribute to be set>);

wdContext.currentRequest_<NodeName>().modelObject().execute();

Hope this helps you.

I get the following error now

com.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception on execution of web service with WSDL URL 'http://srepldev:50400/wsdl/globalweather.WSDL' with operation 'GetWeather' in interface 'GlobalWeatherSoap'

I have written the code as follows:

Webmodel model1= new Webmodel();

Request_GetWeather requestmo= new Request_GetWeather(model1);

GetWeather getweathermo = new GetWeather(model1);

getweathermo.setCityName("CHICAGO");

getweathermo.setCountryName("UNITED STATES");

requestmo.setGetWeather(getweathermo);

wdContext.nodeRequest_GetWeather().bind(requestmo);

try{

wdContext.currentRequest_GetWeatherElement() .modelObject().execute();

wdContext.nodeResponse().invalidate();

}

catch(Exception e)

{

String msg = e.getLocalizedMessage();

if ((msg==null) || (msg.length()==0))

{

msg = e.getMessage();

}

wdComponentAPI.getMessageManager().reportException(e.toString(),true);

}

Hi,

Are you using external web service? if yes then how your WSDL url is showing your server details

If you are using external service then you should set the http proxy settings in the SOA Management -> global settings

Hi Anzar,

You can not check the services from site http://www.webserviceX.NET in webservice navigator. And please have a look in following code snippet

Webmodel model1= new Webmodel();
Request_GetWeather requestmo= new Request_GetWeather(model1);
wdContext.nodeRequest_GetWeather().bind(requestmo); // Please add this line the model node should 
GetWeather getweathermo = new GetWeather(model1);  // be binded with application node
getweathermo.setCityName("CHICAGO");
getweathermo.setCountryName("UNITED STATES");
requestmo.setGetWeather(getweathermo);
wdContext.nodeRequest_GetWeather().bind(requestmo);
try{
wdContext.currentRequest_GetWeatherElement() .modelObject().execute();
wdContext.nodeResponse().invalidate();
}
catch(Exception e)
{
String msg = e.getLocalizedMessage();
if ((msg==null) || (msg.length()==0))
{
msg = e.getMessage();
}
wdComponentAPI.getMessageManager().reportException(e.toString(),true);
}

Give it a try and let us know. The same reply i have posted in your another thread. Please revert back in case of any issue.

HI

I used the code provided by you by I get this error again

com.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception on execution of web service with WSDL URL 'http://srepldev:50400/wsdl/globalweather.WSDL' with operation 'GetWeather' in interface 'GlobalWeatherSoap'

See I ll tell you what I have done.

I have placed my wsdl file by creating a wsdl place holder in our server through visual admin by following steps in the given link.

http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/2684. [original link is broken] [original link is broken] [original link is broken]

I published the webservice through my uddi client and was alos able to search for it and get it in test registry. . But then when I try to import it through the nwds wizard for importing adaptive webservice model and search for it in the client through that wizard I don't get the webservice.

So I decided to go for an alternate way and import the model using the url of wsdl placed in wsdl place holder on our server. But now I am getting this error .

Please guide me if I am going wrong in my approach anywhere. Thanks for your help.Please guide me I want to crack this topic.
