ABAP Web Dynpro V/S JAVA Web Dynpro

We need to pick developing technology between ABAP Web Dynpro v/s JAVA Web Dynpro. Is technology better than other in terms of security, scalability? There is lot of documentation on the web but it is very old and out dated. I am pretty sure things have changed quite a bit with recent versions of SAP. Any feedback is greatly appreciated.

Thanks.

PS: I Used Web Dynpro for ABAP at my previous client for SAP SRM without a problem.

Dear Sap Fan

This has been a long and interesting debate on SDN.

You will find plenty of posts discussing this matter.

But there's no clear winner, I warn you.

;o)

This one in particular is very good:

But you can also check these others:

More and more you see clients migrating from WD4J to WD4A.

Guess SAP is also heading into that direction, perhaps because Oracle bought SUN sometime ago.

I'm comfortable on both environments I have to say.

I have more than 10 years with development.

I know ABAP from inside out.

I also know JAVA and I'm certified with this technology.

But I personally prefer WD4A.

Why ?

Because you don't need to use NWDI.

Because you don't need to configure JCO's.

Because you integrate seamlessly the development with the transport framework (requests, etc..)

Because debugging is great.

Because plenty of traditional ABAP tools (trace, logs, performance analysers, etc..) can also be used with WD4A

Because you don't need to worry with NWDS...just type SE80 and you're there... ;o)

And I could go on and on....

But then again, it all depends:

Do you have a lot of good in-house JAVA knowledge ?

Do you use a lof of Custom JAVA development in your company ?

Are you planning to use standard SAP (ESS/MSS or others for example) ?

I'm not saying that WD4A is "better" than WD4J.

There's no such thing.

Each option has its pros and cons.

You also can't tell that WD4J is more secure or scalable than WD4A. Or the opposite.

And, believe me, WD4J is still going strong with a lot of customers.

But things are changing, and for me WD4A would make more sense if you want to be aligned with SAP.

Now and in the future.

Kind Regards
