Webdynpro Services Exception

[Former Member]

Hi all,

I tried to run sample webdypro program 'WD Tutotial Flight Booking' after configuring SLD.

I got the following Exception.

Hi,

Have you imported the model RFC and deployed it?

Import Model RFC, Rebuid and Deploy your project again.

Hi Luciano,

After configuring SLD, I tried to run the sample program

from EP role Java Developer->Webdynpro , Webdynpro Tutorials-> Tutorials with SAP backend->FlightList / Flight Booking then I got the Webdynpro Services Exception.

Could please suggest how to resolve this problem?

Thanks & Regards

Hi,

Try do these steps:

1- Download the projet and import at your NW Developer Studio.

2- Reimport its Model

3 - Rebuild, deploy and test.

I think that these steps will solve.

Luciano

Hai Vijay,

Have you tested JCo connection working properly? In the content administrator check whether <b>model</b> and <b>metamodel</b> instances for your project have proper JCo connection. After that login into SAP R/3 system with the <u>same credentials</u> in JCo and try to execute the BAPI. You can find out easily what is the problem.

OK,All the best.

Hi Guys,

My problem got solved after restarting the Enterprise portal server.

Thanks for your support.

If the restart does not work, check the connection to the backend. The user system of JCO in question may be in trouble. And if a new model to JCO was never able to cache the structures of BAPIs and for this reason the error is TypeNotFound.

att,

Angelo
