WebDynpro for ABAP Vs Java

[Former Member]

Hi all,

I have recently started learning Web Dynpro for ABAP.

I have worked in WebDynpro for Java.

1)I wanted to understand pros and cons of WebDynpro for ABAP and Java.

2)What are the functionality that are available in Web Dynpro for Java but not in Web Dynpro for ABAP.

3)What should be preferred when considering performance issues - WD for ABAP of Java?

Any Web Log or Link in this context will be helpful.

Thanks a lot,

Rashmi

Hi,

OOPs ABAP uses Classes and Interfaces which uses Methods and events.

If you have Java skills it is advantage for you.

There are Local classes as well as Global Classes.

Local classes we can work in SE38 straight away.

But mostly it is better to use the Global classes.

Global Classes or Interfaces are to be created in SE24.

SAP already given some predefined classes and Interfaces.

This OOPS concepts very useful for writing BADI's also.

So first create a class in SE 24.

Define attributes, Methods for that class.

Define parameters for that Method.

You can define event handlers also to handle the messages.

After creation in each method write the code.

Methods are similar to ABAP PERFORM -FORM statements.

After the creation of CLass and methods come to SE38 and create the program.

In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.

see the links below, Understand them and start developing.

Hi,

in most areas Web Dynpro Java and ABAP are alike, they are based on the same programming model.

In WDA you have the advantage of the integration into the complete development infrastructure, with transport system etc.

As to functionality, there are some UI elements in WDA that are not yet there in WDJ e.g. FormattedTextView.

Web Dynpro ABAP, on the other hand, does not support mobile devices. For more information on WDA, see
