HTMLB, WebDynpro or both together?

[Former Member]

Hi @ all,

I had a look at some possibilities to create Portal Content .

I read something about HTMLB and the comparison to WebDynpro in the SDN Forum.

Some guys are saying that they would prefer HTMLB and some others saying that they prefer WebDynpro.

My question now is, what is the difference for the EP if I have a HTMLB IView or a WebDynpro IView. I know that Webdynpro uses a SLD to get the backend connection and so on.

The Business Logic is fully implemented in R/3 so the IViews are only for displaying content.

Because we have not much time and UI Design in HTMLB take much time, would it be an solution to source out some very complex Graphical UI Views to Webdynpro. I think this would save us a lot of time, or?

Is it possible to access in Portal from an HTMLB to a WebDynpro and reverse? Could I trust in it, that these both different kinds of development will work together?

It would be really nice if someone could give me some good hints and anwsers to this topic.

Thanks and Kind Regards

Dennis

Hi Dennis,

> Some guys are saying that they would prefer

I really depends. First, it depends on experience, even if this is not a really objective comparator... And it depends on what you want to do. If for example you'd need some heavy KM integration, there are many reasons for using HTMLB.

That's a "classical" scenario for using Web Dynpro, for you have some automatism to create the backend connection as well as the mapping of the table values into your UI.

If you have some experience in WD, then yes. If you have no Web Dynpro experience but much experience in HTMLB, then you'd probably be faster in HTMLB and JSPDynPage, but that shouldn't be a reaon to stick to this technique, for once you have gained the necessary experience, at least next time you will be faster

In general: Yes. But that can get quite tricky. If you only want to "enter" the WD app from the JSPDynPage app and vice versa - no problem. If you want to leave the WD app at a certain point but return later - also this is possible in the meantime.

In general they do, but a complete application should be developed in the one <i>or</i> the other technology. Otherwise, you would have mixed UI (even if using the same style, WD and HTMLB pages just look different), double coding for R/3 connection, etc.

Hope it helps

Hi Detlev,

sorry for answering so late.

Thank you for the very detailed pro-con list.

I think I've do use HTMLB because the first part of the application is developed in it.

Kind Regards,

Dennis
