Advantages and pitfalls of WD4A

Hi All.
After my initial exploration of about 20 days in WD4A, I have to tell my boss where does WD4A stand in this whole Netweaver stack.
Also, I have to tell advantages and disadvantages of this tech, along with a comparison with WD4J.
Any type of inputs from you gurus would be welcome.
Thanks in adv.

Hi
Basically there are pros and cons of webDynpro for ABAP .
I am giving you wonderful link that made my many concept clear about WD ABAP and Java .One of which was Support over Mobile Devices .Yet WD ABAP dont have that Provision ,One has to Go for WD JAVA for Developing Mobile SAP solutions .
<a href="/people/oliver.mayer/blog/2006/06/14/web-dynpro-abap-or-java in WD JAVA and ABAP</a>
In my view WebDynpro ABAP and Wd Java are not same.
Basically WebDynpro ABAP and Java are two different webDynpro provided by NetWeaver Stack.
Basic conceptual base of WD ABAP and WD Java is same.I mean to say concepts like Context binding , node , elements , Layout both support are same.
But when you provide background functionality to your Web Screen then Java or ABAP come in to picture.Just take case , you want do some thing on click of some button then
1) in case of java may you will call some ejb or you will may write some java code on click.
2) but in case of WD ABAP you have to do same thing with ABAP classes . You will call some call or some method of some system defined class.
Ulimately point I want make
1) WD ABAP and WD java 's Base is same but you code in completely different way.
2) Purpose for which SAP came with two different WDynpro is different. Java can be used for developing quite sophistcated Web services.
Hope I have clear your Doubt.
Give point if It has served purpose.

  • Advantage and disadvantage of xml publisher, report builder and discoverer

    Hi,
    anyone can explain advantage and disadvantage of xml publisher, report builder and discoverer?
    thanks in advance!

    The best way i found was to put a equals and then double quotes... this only works for excel however it will allow you to cut and paste (ie to use the value to search in Oracle) and also to do vlookups.
    In a bit more detail:
    - I used word to generate my default table
    - this created a field INVOICE_NUM
    - in the cell in the table i put = " before the INVOICE_NUM field and then put the closing " afterwards.
    The theory is that excel will concatenate the values together... because it has quotes around it, it will treat it as a string rather than simply a value.
    For any other formats this will not work.
    I'm guessing most people have moved on and resolved this some other way, but just thought I'd share the wealth!

  • Advantages and disadvanteges with static methods

    Hi,
    Can anybody suggest me the advantages and disadvantages of static methods? In my project i am using templates which are used by different programs and in that templates i am using static methods.
    It is web application. is there any problems if made methods as static in templates that are used by diferent clients?
    Thanks
    Karimulla

    A static method can't be overridden, and static methods are usually only used for some utility methods and other things which don't belong to the class. I would probably not make the methods static.

  • Advantages and Disadvantages of Dual booting Windows on PXI Device

     
    Hello,
    In solving my previous problem of running a DLL in RTOS I've stumbled upon another solution. But i wanted to know the pros and cons of this before i make the leap.
    I want to install windows on the PXI device so that the NHR DLL files are run inherently on the windows kernel and i have access over my DAQ devices without placing them in the remote target.
    What are the advantages and disadvantages of installing a windows only on the DAQ device and running all my operation from it. Do i loose my real time features? I dont know, I'm really new to LabView and may sound really dumb. Please excuse my lack of knowledge.
    With Regards,
    Khalid.

     
    Hello Bob,
    Thank you for your insightful answer. I also thought this might happen, loosing all the RT features.
    I have another question for you. If i use a RT variant of windows like "Windows Embedded 8", will this make any difference? Can i regain my RT features by it or i have to go with the LabView RTOS.
    I'm pushing towards a windows system because i have to run this DLL file from NHR which is not supported by the LabView RTOS.
    Moreover, I could just install just windows onto the PXI controller. I'm not being able to make it dual boot. Can you guide me towards proper guideline to do so? I looked at the knowledge base file about dual booting, but the instructions dont exactly match with my available options in BIOS setup.
    Any suggestions from anyone is much appreciated.
    With Regards,
    Khalid.

  • Singl/Multiple Server Oracle 10g DB and AS- Advantages and DisAdvantages

    Hi Friends,
    I am using Application1 using Oracle 10g Application Server and Oracle 10g database.
    Now i planned to use Application2 using Oracle 10g AS and Oracle 10g DB
    I need to know what will be the Advantages and Disadvantages if i have the schema for Application2 in the existing Oracle 10g DB / having it in another Oracle 10g DB Server
    sameway what will be the advantages and disadvantages if i have the Application2 regsiterd in existing Oracle 10g AS(Multiple OC4J Instance) / having it in another Oracle 10g AS Server.
    Regards

    To start the list, for me some of the advantages are:
    Same DB:
    - less overhead and wasted CPU Cycles (therefore potentially lower license fees)
    - easier maintenance (backup, recovery)
    - easier tuning (fewer conflicting external environments asking for same resources)
    - Oracle is designed for this, allows use of Resource Manager
    - technically RAC is a clustered 'same DB'
    Same AS:
    - less overhead and wasted CPU Cycles (therefore potentially lower license fees)
    - easier maintenance (backup, recovery)
    - easier tuning (fewer conflicting external environments asking for same resources)
    - Oracle is designed for this, use AS clustering
    Different DB:
    - separate maintenance (patch, upgrade) cycles for different SLA
    - easier tuning (isolate tuning to one app)
    - easier security (most developers have no idea about Oracle security and make merge impossible)
    Different AS:

  • Advantage and Disadvantage of user login ID

    Dear SAP expert,

    Hi Nitin,
    A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms
    the virtual table returned by the view. A user can use this virtual table by referencing the view name in Transact-SQL statements the same way a table is referenced.
    For more information about the advantages and disadvantages of views in SQL Server, please refer to the following two articles:

  • Advantages and Disadvantages of BEx Analyzer

    Dear All,
               Please specify the ADVANTAGES and DISADVANTAGES of using BEx Analyzer for reporting over a browser.Does the analyzer provide better performance?generate exhaustive reports?and found better by users since it is excel based?
    Yours truly,
    Ratish
    [email protected]
    +919820827647

    Hello Ratish,
      The advantages and disadvantages are primarily based on the light weight client and heavy client.
    Excel -
    1. It is heavy weight and needs a client installation
    2. Analysis is easier , as excel functionalities can be used over BI data
    3. People who know excel will like this
    Web-
      1. It is light weight and no installation needed at the client as browser will be available
      2. Can not analyze the data from the report ( you need copy to excel)
    In simple analysts and expert users like excel.
    Users who just view the report and no more analysis will be happy with web.

  • What are advantage and disadvantage for Physical Standy and Logical Standby

    HI,
    What are advantage and disadvantage for Physical Standy and Logical Standby configuration?
    Thanks
    Ken

    Logical standby database
    The key advantage for logical standby databases is that they're opened read/write, even while they're in
    applied mode. That is, they can be used to generate reports and the like. It is indeed a fully functional
    database. Also, additional indexes, materialized views and so on can be created.
    However (this being a disadvantage) not all datatypes are supported.
    Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into
    SQL statements and replays them on the logical standby database.
    Physical standby database
    A physical standby database is a byte for byte exact copy of the primary database. This also means that
    rowids stay the same in a physical standby database environment.
    Oracle (or more exactly the log apply services) uses the primary database's redo log to recover the
    physical database.
    A physical standby database might be opened read only; however, the received logs are in this case not
    applied. When the logs are applied, the database is not accessible (it is then in a managed recovery state).

  • Advantages and disadvantages of having 2 controlling areas.

    Dear All.
    My client have 2 company codes and will use same fiscal year variant and chart of account. so we recommend for one contrilling area. But my client wants some document or wants to know the advantages and disadvantages of having 2 controlling areas.
    I will really do appreciate if anybody hepls me in this regards.

    there is no general correct answer as every case is the different.
    However, the majority of solutions that have a single CoA will also have a single Controlling Area.
    The Controlling Area is the highest reporting level in Controlling, PCA, CCA etc.
    Normally if you have two CoA then you will have two Controlling Areas.
    A simple point to make to them is that a Controlling Area can only have 1 CoA, therefore you cant have 2.
    Are your Company Codes in the same Country?

  • Advantages and Disadvantages of  Applet over JSP/servlet

    Can some one please let me know what are the major advantages and disadvantages of using Applets over JSP/Servlet technology?

    Well, a servlet / jsp is generated on the server, an applet on the client side. That's the most important difference.
    Appelt's usually are for little applications like games and stuff, you can run in a browser.
    Servlets are for dynamic pages, for example database-viewing and stuf...
