Where MVC patten is used in WEBDYNPRO

Hi All,
I worked on BSP and webdynpro.
I am having the following doubt.
In Webdynpro,  how exactly the MVC architecture is followed.
In BSP  :  we are creating the global class ( Model ).  when creating the controller , in DO_Request we are calling that model.
Then passing the output to page.
But In webdynpro:   How the model ?   where we are calling that model.
as per my knowledge:  in View methods  like WDDOINIT, WDDOMODIFY....
we are creating ref to some standard classes .  Not user created ( Z class).
Then my final question is   where and how MVC architecture is used in ABAP WEBDYNPRO...
pls explain with small example.
Regards,
Kishan

Hi nSharath,
thanks for your reply.
evry where, people will say that WEBDYNPRO for abap   works with MVC pattern right?
then why there is no Model?
even, controller is not available right?  only component controller to define nodes and attribures....
Can we use a global Z class in Webdynpro , like we use in bsp?
just confused with MVC with webdynpro...
Regards,
Kishan

  • Standard program to display which tables are used by Webdynpro ABAP program

    Hi Gurus,
    I am working on a couple of enhancements in SAP Promotion Management for Retail (SAP PMR) which works on the principle of Floor Plan Management.
    I was wondering if anyone would know of a standard program to display the tables used by Webdynpro ABAP?
    (or)
    Where can I get info of SAP Tables associated to SAP PMR?

    Hi,
    I am not aware of any standard reports that displays the tables.
    If I have to view the tables, I would go to se80, give the package and view all the tables in the package.

    hi all friends,,

    Hi
    Web Dynpro for ABAP - Getting Started
    Web Dynpro for ABAP is SAP’s new standard UI technology for developing user interfaces in the ABAP environment. In the long term Web Dynpro for ABAP will be the successor of the traditional screen (“Dynpro”) based user interface technology which is based on the SAP GUI. Available with NetWeaver 7.0 (2004s) Web Dynpro for ABAP provides the same declarative UI development paradigm as Web Dynpro for Java directly out of the NetWeaver ABAP Application Server. Web Dynpro for ABAP allows the development of user interfaces directly within the ABAP Workbench (SE80) and the Web Dynpro runtime environment is a central part of the ABAP server and can be used in any SAP solution based on NetWeaver 7.0 (2004s) without the need of an additional server installation.
    Web Dynpro for ABAP allows the development of user interfaces in a declarative way by providing a mighty framework which abstracts the rendering technology from the core UI definition tasks. The Web Dynpro developer declares the layout and behavior of the UI without caring about HTML, JavaScript, browser specifics or the HTTP protocol. Instead the focus lies on designing graphically Web Dynpro components based on the Model View Controller model, which enforces a clear separation between the UI layer and the underlying business logic.
    This declarative Web Dynpro programming model enforces the developer to focus on the tasks of
    Designing the layout of the visible views (where should the table be placed, do I need tabs, how should the button look?)
    Declaring the flow and behavior of the application (flow between views, which event is triggered by which button click, etc)
    Defining the data binding (which internal table is displayed in a specific table, etc)
    Implementing the event handlers and controller methods.
    Without making any assumption about the used rendering technology, like which browser should be supported or if the Web Dynpro application will be later displayed in a web browser via HTML at all or in another kind of client with completely different rendering capabilities.
    The Web Dynpro Frameworks provides all important UI features directly out of the box:
    All elements (tables, buttons, trees, dropdown list boxes, etc) necessary for state of the art user interfaces are provided by the Web Dynpro Framework in the form of predefined UI element libraries.
    Complex features and behavior of UI elements.
    Internationalization of the UI. All visible strings in a Web Dynpro ABAP UI are handled by the translation system and are translated in the same translation environment like other ABAP language dependent resources. All texts are displayed automatically at runtime, dependent of the user’s credentials.
    Accessibility features are directly built into the framework and UI elements.
    A unified rendering engine generates at runtime the data which is sent to the specific client application, which is not limited to browsers but includes the NetWeaver Business Client.
    All this is available in the established environment of the ABAP application server and well known capabilities like the transportation and change management system, security environment, test and performance analysis tools or remote debugging can be used like in common ABAP development.

    The first thing I would suggest is for you to go to the folder containing your catalog, using your system browser. There will be a folder that has the extension .lrdata. Delete that folder, and then try to start Lightroom. If that doesn't work, replace your catalog with your most recent backup.

    What really cheeses me off here is that Apple isn't allowing users enough customization.  With each update of iTunes (and the OS and iOS) we're forced to give up something that worked well for the way we want to use the app and make do with fewer (and lamer) options.  If Apple keeps this up, they're going to start losing customers fast.  I mean if this isn't fixed soon, I'm pretty sure I'm going to give up on iTunes, and then I'll probably go ahead and get a Galaxy when I need to replace my iPhone.
    What I don't understand about how they won't let users delete the list of available podcasts now is why?  How is this making it a better program?  I can understand that not all users are capable enough to right-click on a feed and select "Show all available episodes", so I can see why they want the complete list to be the default (and, surprise, it already was).  But to not give users the option to delete that list?  It's inconsiderate because it makes navigating feeds with a large back catalogue really frustrating.  I'm flabbergasted that no one at Apple considered all the podcast feeds that keep hundreds of episodes available when they removed this feature.  It smacks of rank incompetence.
    What improvement were they trying to make here anyway?  There was nothing wrong to my mind about how podcasts were managed in previous versions.  Whatever improvement they were trying to make here, they should have realized that many users would at least want the option to keep things the way they were.
    And reverting to a previous version is no solution.  I can't sync my iPhone with the new iOS without this update, and (while I do have some issues--specifically how you can't play podcasts in the Music app anymore) I do like the new iOS.

  • How do I find where an effect was used?

    Hi -
    I'm running AE CS6 (on MBPro OS X 10.7.5) and I just re-opened a file made with AE CS4 that uses some BCC plug-ins which I haven't re-installed in CS6. I got an alert that some effects were missing from the project.  I'd like to find out where the effects are used in the project so I can delete them and end the alert message's reign of terror.  Is there a shortcut way of doing that or must I hunt through every layer manually?
    TIA your advice,
    JL

    Removing an effect from a composition will not cause AE to be unable to launch entirely.
    Can you open AE and create a new project?
    Do you happen to know the exact version number of AE? It should be 11.0.2 (although, if you're a cloud subscription member, it shouldn't start with an 11 at all )

  • When and Where and how to use Proxies

    hi
    New to Xi Can anyone explain When and Where and how to use Proxies
    Mohit

    Proxies: are interfaces which will get executed in the application system.They can be created only in the system from message interfaces using the proxy generation functions.
    The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
    The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.
    The Proxy currently has the following components available:
    1. ABAP Proxy – Communication using XI or Web Services
    2. Java Proxy– Communication using XI (J2EE)
    JAVA Proxies:

    Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.
    ABAP Proxies uses Webservice and Http Protocols. And if you use RFC it is mainly meant for Sync. call. But Proxies is used for both Sync and Async.
    If you use ABAP Proxy , you can reduce the overhead calling the function again and again.

    Re: JDBC Sender select/update problem
    If u generate proxy for outbound interface then its client proxy and for inbound interface its server proxy.
    In client proxy u can call the method to send messages but u can't modify it but in server proxy its possible to write a user code within the method to execute proxy.
    CLIENT PROXY:
    A WSDL description from a UDDI server (or an Internet page) is usually used to make a service executable in the Internet and to describe the interface of this service. You require a client proxy and not a server proxy to call this service by using the Web service infrastructure.
    SERVER PROXY:
    You can only generate ABAP server proxies from a WSDL description if they originate in the Integration Repository.You can also generate server proxies for Java and client proxies for ABAP from message interfaces.

    I'm not sure what the benefit is of knowing how often an
    image is used, but
    a search for the image by filename would do the trick.
    And just so you'll know, this is a peer forum, not an
    official communication

  • Any way to search places where a style is used in RH?

    Hi
    I've a few questions about style management:
    Is there a way to search for where a style is used in a project or topic?
    If so, is there a way to search-and-replace, ie, find where a style is used and replace it with another style?
    When deleting a style, is there a way RH can be set to display a warning if the style to be deleted is being used anywhere?
    FrameMaker handles the above use cases very well. However, I can't yet see how these actions are done in RH.
    Thanks!
    -Kurt

    RH doesn't warn you if you delete a style that is in use.
    If you want to replace a specific style with another one, the easiest
    way is to use a search and replace operation. For example, to change the
    style 'myStyle1' into 'myStyle2', use the following search action:
    class="myStyle1"
    and replace by
    class="myStyle2"
    Make a backup before doing this though, as you can cripple a project in
    seconds.
    Kind regards,
    Willam
