Former Member

Hi,

I will develop a web dynpro application which will run in the EP and use an DB. How are the best practices in this scenario ? Should I use a Web Dynpro Model (EJB or WebService) for the persistence operations or should I use Portal Services ?

Regards

Flo

Hi Florian,

Access DB using web dynpro Model with EJB is better option.

later on u can create an webdynpro iview and can implement this application on EP.if u want to use application directly via url u can go for web services.

As per my knowledge portal services would be the best option when comparing with EJB, because EJB is a heavy weight component.
