Error running Web Dypro application that uses an Adaptive RFC Model

[Former Member]

Hi,

I am trying a sample case study Web Dynpro application which uses Adaptive RFC Model. The application development in NetWeaver 7.0.0 went fine.

I am also able to configure SLD Data Supplier settings in the Visual Administrator and a corresponding JCo Destination in the Content Administrator.

Though the deployment is successful, I get an exception when the application is run.

I'm producing the top part of the stack trace below

The type in question is available in the IDE (i.e in the source development project in NetWeaver).

I'm new to NetWeaver as well as the J2EE Engine. So, I have no clue as to what may be wrong. I was able to deploy and run sample applications which didn't use Models or Context-Model data binding, though.

All help is welcome. Please let me know if the full details of the error is needed.

Hi,

Thanks for the solutions.

I can't say I understand Ulli Hoffmann's solution. This is definitely because I don't know the workings of J2EE Engine.

But I have created only one JCo-connection as Achim Hauck predicted. I'll try creating the two connections and post the results. With hindsight, I remember mentioning two names in the Create Model Wizard for model data and meta-data.

Thanks and regards,

Amshuman

[achim_hauck2]

you'll need 2 jco-connections. one for data & one for meta-data.

did you test both successfull in content administrator?

kr, achim

Hi,

there are two problems involved here:

1) in one recent 700 installation the java dictionary runtime has bug, which causes the stack trace being incomplete

For that you need to get a new SapDictionaryTypesRuntime.jar.

2) when this one runs fine your stack trace should include a message saying '... failed to create provider: Field LTRFLDDIS not a member of DFIES'.

This is now the actual problem in your installation. The JCO doesn't work with a recent 700 dictionary modification.

To fix it you will need a new jrfc.jar. Check out note 802727.

regards, Ulli
