WebDynpro vs Oracle

[Former Member]

Greetings to all!

We had been two weeks trying to develop a simple application with Web Dynpro that brings data from an Oracle database. We have defined a table in the Java Dictionary with such fields and names that in the data base. We have created a project J2EE with a EJB Entity with properties and methods for the fields of the table. For the tableView model in Web Dynpro we had to use a Java conventional Bean since it did not accept the EJB import directly. Also we have defined a system with the connection properties, user, password... of the Database. Everything seems to work fine, but sometimes we obtain the java.lang.NoClassDefFoundError exception: com/sap/tc/webdynpro/progmodel/gci/IGCIComponentDelegate and the others just an empty tableView. Can somebody help us? It would be to us of much utility a simple project of this kind with all the properties, detailed references...

Thank you very much in advance.

Hi!

Now you mention it. I´m getting a warning when trying to deploy the WebDynpro proyect once the ear file of the J2EE project seems to have been sucessfully deployed:

Caught exception during application startup from SAP J2EE Engine's deploy service:

Hope it helps. Thanks.

You seem to have a newer Web Dynpro version in your developer studio than on your Web application server.

Can you check this?

I've got the NetWeaver Developer Studio 2.0.9 and the WAS SP9. Isn't this right?

Thanks Armin.

Do you get this error when you deploy from SP9 NWDS to SP9 WebAS? I doubt this.
