i came accross this error when i deploy and test a web dynpro project.

in this project, i add a web services model depreciated into the WD project.

the web serives is tested ok before i import it to my WD. the function of this WS is to gather a input and return it in upper case.

can anyone came accross similar problem and found the solution?

thanks.

This line cause the problem:

wdContext.currentxxxxxElement().modelObject().execute();

-

---

More information on the implementation:

try {

wdContext.currentRequest_CalNganViDocument_changeCaseElement().modelObject().execute();

wdContext.nodeResponse().invalidate();

String result = wdContext.currentResponseElement().getResult();

wdComponentAPI.getMessageManager().reportSuccess(result);

}

catch(Exception ex) {

wdComponentAPI.getMessageManager().reportException(ex.getLocalizedMessage(),true);

}

Hi ENg beng LEe,

Before executing the WebService model have u created the object of the Node, ie

before this line,

wdContext.currentxxxxxElement().modelObject().execute();

<RequestNode> objReq = null;

try

{

objReq = new <RequestNode>();

wdContext.node<RequestNode>.bind(objReq);

}

Try this out. this might be causing the problem

Hi

thannks Poojith.

I did add the code in WdDoInit method.

please guide me further...

the webservices print screen:

http://i95.photobucket.com/albums/l147/leeeb/method.jpg

here is the code in ini method:

//@@begin wdDoInit()

Request_CalNganViDocument_changeCase req = new Request_CalNganViDocument_changeCase();

wdContext.nodeRequest_CalNganViDocument_changeCase().bind(req);// nodeWebServiceEmail().bind(req);

//@@end

and the action of button:

//@@begin onActionsend(ServerEvent)

try {

wdContext.currentRequest_CalNganViDocument_changeCaseElement().modelObject().execute();

wdContext.nodeResponse().invalidate();

// String result = wdContext.currentResponseElement().getResult();

// wdComponentAPI.getMessageManager().reportSuccess(result);

wdComponentAPI.getMessageManager().reportSuccess("dala");

}

catch(Exception ex) {

wdComponentAPI.getMessageManager().reportException(ex.getLocalizedMessage()+"no method",true);

}

//@@end

Hi..

Try to Repair the project

i.e right click go to Repair ->Project Structure and Classpath

And then try to Rebuild and Deploy the project.

Or It must be versioning problem...

Hi

I meant to say your NWDS version and WAS version

NWDS version must always be lesser than or equal to the WAS version i.e

NWDS is 04 and try to deploy in 04s server or vice-versa may lead such problems...
