webdynpro and uwl

[Former Member]

Hi,

I'm trying to use the UWL-API as described here within my Web Dynpro-App. My coding looks somehow like this:

IUWLService uwlService=(IUWLService)PortalRuntime.getRuntimeResources().getService(IUWLService.ALIAS_KEY);

UWLContext myContext = new UWLContext();

try {

IUWLSession mySession = uwlService.getUwlSessionForWebDynproClient(myContext);

} catch (Exception e) {

IWDMessageManager myMan = wdComponentAPI.getMessageManager();

myMan.reportSuccess(e.toString());

}

Well when i deploy that app and run it (i integrated the app into an iview, although i'm not sure whether have to or not) i get the following error:

java.lang.NoClassDefFoundError: com/sap/netweaver/bc/uwl/IUWLSession

Maybe i have to add a sharing reference or s.th. similar in order to use that API?

I'll reward points for any useful answer.

thanks a lot

Hi Lionsir,

The syntax of Sharing refrence is :

PORTAL:sap.com/< your service name>

just try this once.

Thanks & Regards,

Hi Namrta,

Thanks for your response.

I have tried to add Share Reference "PORTAL:sap.com/com.sap.netweaver.bc.uwl".But it does not solve my problem and the error is same.

Any more ideas?

Hi,

I just tried to execute the same in my portal, It returns "Portal Runtime Error", I have declared the library reference and also included the corresponding JAR files.

Can u just guide me the the steps u followed to achieve the task to trigger a notification from WebDynpro.

Hi Lionsir,

You are correct, you have to add the either the library or the sharing refrence for the UWL API.

We get these error when the appplication doesn't find the jars at runtime.

Thanks,
