Java package concept in ABAP Objects

Hi, just a question on grouping of classes in ABAP Objects.
In Java, you can group classes by "package" to avoid
namespace collision, my question, in ABAP Objects, how
do you group classes to avoid namespace collision?
I know that there is package concept in SAP/ABAP but it
is different concept in Java.
Thanks in advanced for your reply.

Hello One and Lonley,
the package concept in ABAP and Java is quite different. In java the package name is part of the development object in ABAP not. So any class pool name is global unique. In combination with the restriction on 30 chars this leads often to somehow cryptic names.
The only way to escape this somehow is the excessive use of local classes. That mean classes defined within main programs. If you are on 7.00 you may check FuGr SAPLSAUNIT_TREE_CTRL_LISTENER for this technique.

Best Practice: Usage of the ABAP Packages Concept?

Hi SDN folks,
I've just started on a new project - I have significant ABAP development experience (15 years+) - but one thing that I have never seen used correctly is the Package concept in ABAP - for any of the projects that I have worked on.
I would like to define some best practices - about when we should create packages - and about how they should be structured.
My understanding of the package concept is that they allow you to bundle all of the related objects of a piece of development work together. In previous projects - and almost every project I have ever worked on - we just have packages ZBASIS, ZMM, ZSD, ZFI and so on. But this to me is a very crude usage of packages, and really it seems that we have not moved on passed the 4.6 usage of the old development class concept - and it means that packages do not really add much value.
I read in the SAP PRESS Next Generation ABAP book (Thomas Ljung, Rich Hellman) (I only have the 1st edition) - that we should use packages for defining separation of concern for an application. So it seems there they are recommending that for each and every application we write - we define at the least 3 packages - one for Model, one for Controller and one for view based objects. It occurs to me that following this approach will lead to a tremendous number of packages over the life cycle of an implementation, which could potentially lead to confusion - and so also add little value. Is this really the best practice approach? Has anyone tried this approach across a full blown implementation?
As we are starting a new implementation - we will be running with 7 EHP2 and I would really like to get the most out of the functionality that is provided. I wonder what others have for experience in the definition of packages.
One possible usage occurs to me that you could define the packages as a mirror image of the application business object class hierarchy (see below). But perhaps this is overcomplicating their usage - and would lead to issues later in terms of transportation conflicts etc.:
                                      ZSD
                                        |
                ZSOrder    ZDelivery   ZBillingDoc
Does anyone have any good recommendations for the usage of the ABAP Package concept - from real life project experience?
All contributions are most welcome - although please refrain from sending links on how to create packages in SE80
Kind Regards,
Julian

Hi Julian,
I have struggled with the same questions you are addressing. On a previous project we tried to model based on packages, but during the course of the project we encountered some problems that grew overtime. The main problems were:
1. It is hard to enforce rules on package assignments
2. With multiple developers on the project and limited time we didn't have time to review package assignment
3. Devopelers would click away warnings that an object was already part of another project and just continue
4. After go-live the maintenance partner didn't care.
So, my experience is is that it is a nice feature, but only from a high level design point of view. In real life it will get messy and above all, it doesn't add much value to the development. On my neew assignment we are just working with packages based on functional area and that works just fine.

Some documents to read as a starter in abap objects.

Hi All,
Need a help, I have read the basic concepts in ABAP objects, uptil cath try....... and event handling.
However once this basoc reading is over, suggest me some additional links to read from, i wanna read more and learn since in my company there isnt much of exposure to object oriented concept in ABAP.

ABAP Object oriented practice..

Hi,
I have gone through the basic concepts of ABAP object oriented programming using links provided by other sdn fellows. But this has not built thorough confidence.
I request someone to suggest or send me some material which has some ABAP object oriented exercises along with the solutions so that I can re-do it and boost my confidence.
Thanks.
Regards,
Rajesh.

Notes on using Object oriented concept in ABAP

Hi ,
I want somes notes on how to use Object oriented concept in ABAP.
Thanks in advance.
Chetan

Hi, this may help you
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.
Example:
REPORT sapmz_hf_alv_grid .
Type pool for icons - used in the toolbar
TYPE-POOLS: icon.
TABLES: zsflight.
To allow the declaration of o_event_receiver before the
lcl_event_receiver class is defined, decale it as deferred in the
start of the program

Changes to ABAP Objects via Notes/Packages

Hi,
Is there perhaps a mechanism where one can check all notes/packages that have impacted an ABAP object?
Thanks in advance.
Regards,
Kennedy.

Hello Kennedy
If a SAP Note would consist exclusively out of customizing then you have no direct impact on any ABAP "objects".
Otherwise you will always affect repository objects.
You may define a filter of object types (R3TR ....) which you regard as impact on your ABAP objects. Using this filter you can check the contents of a note or EnhPackage(?).

Calling inactive version of ABAP object from Java

Hello,
When I call an ABAP object from Java Program which version of ABAP object is called inactive or active ?
Is there a mechanism to call the current inactive version or any other previous inactive /active versions ?
Regards,
Tarun

Only the "active" version of ABAP code is active and runnable.
You cannot run inactive versions. Like you have to compile a .java file to a .class file o make it runnable in the JVM.

Convert JAVA Web Dynpro to ABAP Web Dynpro application

Hi,
I was hoping someone could tell me if there is a way to port a JAVA Web Dynpro application to ABAP Web Dynpro. We have some JAVA WD apps that would now make more sense to have running on our ABAP system so we would like to convert them to ABAP WD apps.
I know the theory is that WD is metadata/XML based so it should be possible to port the WD definition to ABAP and have the ABAP runtime generate the application again in ABAP. I expect that any custom code that is written in JAVA would need to be manually rewritten in ABAP - but it would be great if there was tool or method to at least port the majority of the application.
Thanks in advance for your help,
Simon

Hi Simon
You are correct in thinking that all WD apps are based on metadata, but unfortunately, the similarity between WD Java and WD ABAP is just a conceptual one, and no such tool exists to convert one to the other.
In addition to this, there are certain implementation differences between ABAP and Java that mean you could not convert one to the other. For instance, the whole concept of model objects does not exist in WD ABAP. Therefore, structural entities used in WD Java such as model components could not be tranlsated into anything that exists in ABAP, because the concept is redundant in the target language.
Sorry about that, but Java and ABAP are sufficiently different beasts that such a tool is not possible.

ABAP Objects Design/Organization Issues

Hi,
I'm trying to design and implement reusable components using ABAP Objects. I'm familliar with OO concepts and have developed a few applications using C++ and Java.
I'm trying to organize my classes into separate source files (include program in ABAP).
ie.
include program a
CLASS a DEFINITION.
ENDCLASS.
include program b
INCLUDE a.
CLASS b DEFINITION.
data x TYPE REF TO a.
ENDCLASS.
Lets say I want to write a report that uses both objects a and b. That means I have to include both programs. but since program b includes program a. including both programs a and b in my report would produce redeclarations of class a.
executable program c
REPORT c.
INCLUDE a.
INCLUDE b. " error: redeclaration of class a
DATA: x TYPE REF TO a.
y TYPE REF TO b.
This bothers me. Although it would be possible to just include program b, it would be a bit awkward since, i dont care if class a was used in the implementation of class b. Implementation should be abstracted from the user. Besides, everything should be explicit.
Is there a way to organize things as such? Would importing these classes globally would solve the problem.
Thanks.

Emir,
The way we do OO Programming in ABAP and other languages differ.
In your case, it might be a better option to create these classes as global classes, so that you will not have this issue. You can SE24 to do the same.

Ravi
