Interface method in enhancement mode

Hello Experts,
I need to enhance a standard web dynpro component. I have created a new method in the component controller using enhancement implementation. This method has to be called from another component. Therefore I need to make this as an interface method. But in enhancement mode I do not see an option to make this method as an interface mathod. Kindly let me know if this is poosible.
Thanks,
Pooja

How to enter Enhancement Mode of ABAP OO Classes: Add Methods, Pre-Methods.

Hello,
do you know how to enter the enhancement mode of the class builder?
I want to enhance a standard global ABAP OO class by implicit enhancements for inserting methods, attributes or pre- and post-methods - as described in <a href="http://help.sap.com/saphelp_nw70/helpdata/en/58/4fb541d3d52d31e10000000a155106/content.htm">Online help</a>.
I start the SE24 on my NW 7.0, but there is no menu Edit-> Enhancement Operations-> Enhance Class/Interface as written in <a href="http://help.sap.com/saphelp_nw70/helpdata/en/86/b83142680d5c33e10000000a155106/content.htm">Online Help</a>.
When I press the Display button, there is no enhancement button (the spiral), and the sub entries of menu Edit-> Enhancement Operations, like Insert Pre-Method are inactive (gray).
In SE80 I don't find them too. The only implicit enhancements I found are on the beginning and end of methods implementation code.
Do you have experience enhancing classes?
Best regards
Michael Umlauff

Hallo Michael,
You first have to go in se80 or se24
Then menu Class-> Enhance
Then you will be able to use Edit-> Enhancement Operations-> Insert Pre-Post Methodes

Add an interface Method/Event via enhancement??

Hi expert.
I want to pass additional data between two standard webdynpro components. As for as I know, I can use infterface method/event in custom webdynpro component and click check box 'Interface' of method/event.
However I can add new method/event in standard webdynpro via enhancement, the check box 'Interface' is dispear.
So is it possibe to add an interface method/event via enhancement? or pass additional data between standard webdynpro component?

Hi,
First you need to understood the standard webdynpro component which you are looking for.
If the standard component is providing interface methods/events then you can call from your custom webdynpro component re-using the standard component in your custom component.
If you provide mroe information about which standard component and which event/method you are looking for, so that I will provide more info.
Best of luck..

You cannot perform this action in modification/enhancement mode

Hi,
I want to delete an interface (IF_EX* --> in the sap namespace) an the following message appears:
"You cannot perform this action in modification/enhancement mode" (Message Class OO, Message Number 401)
The interface was created by myself in a SAP development class / package.
I think the problem is, that the system is trying to delete the interface by using the modification assistant.
Regards,
Hendrik
BTW: It is a customer installation, not a SAP internal development system

Hi
How did u create an interface with name beginning with IF_EX*, the standard interfaces for BADI should have a name like that.
If you've create a custom interface it should be called Z*.

Accessing an app.module's client interface methods in other app module

Hi all,
We are developing an application with number of projects (one for each module). We have got a common project with an application module, entity and view objects which are common for the entire application. For reusability, this common project is shared in session scope since most of them are of static nature.
In the shared application module's implementation class, a common method has been included that will be used for data filtering by constructing/appending where clauses in a particular application scoped view object. This method has been exposed as client interface method so that other projects can make use of it. The common project is compiled as an ADF Library jar for accessing it in other projects.
For accessing the exposed client interface method, from the view controller layer, we can include its reference in the page definition file and can execute the method from a managed bean by finding the operation binding from the page definition. But, in case if we wish to access the method in another model project, we could not do so.
Now, my questions are:
1. Is it the correct location(Shared App Mod. Impl) for including the logic to filter the data?
2. Is it possible to access the app. module impl method in another project's impl classes (Let it be entityImpl or viewObjectImpl or viewRowImpl or AppModImpl) ?
3. If it is possible, how it has to be done?
Thanks and regards,

Redefine Interface Method

Hi, I am using a BI Interface "IF_RSCNV_EXIT" and I am adding code to the "Exit" Method.
Do I need to redefine this method? The reason I ask is because the redefine icon is greyed out even though I am in edit mode.
Thanks!

Hello Kenneth
Interface methods are always empty. You can implement them only once within a hierarchy of classes using this interface. Thus, you cannot redefine it.

Create interface method in standard component.

Hi Experts,i want to enhance standard component.in that i created one attribute and i used in my component.For that attribute the value is passing from some other component.i try to create interface method in standard component.but it is not possible.so please help me out this issue.
Regards
prasad

Hi,
No, You cannot create Interface Methods/Nodes in Standard Component by Enhancing. I would suggest to create a Singleton class and create your method in that class and can access across components.

When will Office 2013 Offline File Cache for IE add in work with Enhanced mode?

The Office 2013 Document Cache Uploader IE Plugin is incompatible with IE 11 running in enhanced mode.
I read that enhanced security mode was enabled by default in Win8 so Microsoft can collect information and advise third party plug-in developers they need to update their stuff to work with it. Then in November, Microsoft started shipping Win8 with enhanced
security disabled. But Win8.1 now ships with enhanced mode enabled... But... Microsoft's own plug-in with the latest versions don't work with it. The solution / workaround is to disable enhanced protection mode. (I don't see this
as a solution for me, my last virus infection because of insecure IE cost me over $400 to fix.) When are you going to fix your own stuff? Or will you retire it like a bunch of other goodies ripped out of Win8. And Server 2012. And Exchange
2013........Lastpass.com has their plug-in working with enhanced mode... Why can't you fix it? Should not be that tough to fix and to include it in a Office update....

Hope there will be a fix soon....This should not be marked as 'answer'. You simply state the fact that it is broken as I did and to disable IE Enhanced (warning/warning) and that is not an answer or a workaround..
Somebody please at least look at it and come up a quick and cheap, down and dirty way to add this to the trusted zones so it will work? then you can mark as answer. Everyone there at Microsoft sitting around waiting for someone else
or other department to do it. Lastpass make it work, Logmein make it work, but Microsoft resting on their laurels .......My gosh, I paid $439 for a copy of Office Pro 2013 Professional to upgrade my Office 2010 and it does not work as well as 2010 did?
In this respect, the product is a Lemmon. I already moved to the cloud for Exchange like they wanted me to, by crippling connection with this to my church's Exchange 2003 server.
It seems the master plan behind this release is to disable function with Server2003 to drive more Exchange server or Cloud hosting sales. Please make sure the product does what it did before, before you take my money and turn off the lights on important
feature oversites.
Any way to hack into Office 2010 and load its cache uploader to run in enhanced zone, or put a link or dll in the trusted zone to make this feature work again? Can someone at Microsoft at least get it on the project board or bump it up a hundred spaces
on priority list? Maybe offer a bonus to the programmer that fixes it. A weekend on the hiking trail or kayak excursion, or rock-climbing pass.. Microsoft guys like that outdoors kinds of stuff and will work like crazy to get it.

How to display web interface in full screen mode

Hi,
I would like to view my web interface in full screen mode in internet explorer. Is there anyway we can switch off the toolbars and URL automatically while calling the web interface
Thanks
SR

Hello SR,
I don't think it is possible to do this directly in the web interface. Otherwise many websites would change your browser settings.
It's possible to set the window properties, when the window is opened from JavaScript for example. So you could create a dummy start page and add some JavaScript to open a window for the web interface with the settings you require. Here's a good page that explains it:

Access specifiers for interface methods

When we implement the interface ,we have to specify the implementing method access specifier to be "PUBLIC" ,but not "PROTECTED" or "PRIVATE".
Compiler is giving an error -- attempting to assign weaker access privileges ,when we specify protected.
what is the internal reason for this?Why we shouldnt make the access weaker in the implementing class.
Can any one help me on this.Your help is highly appreciated.

When we implement the interface ,we have to specify
the implementing method access specifier to be
"PUBLIC" ,but not "PROTECTED" or "PRIVATE".
Compiler is giving an error -- attempting to assign
weaker access privileges ,when we specify protected.
what is the internal reason for this?There is absolutely no point in having a private interface method. The interface represents a visible abstraction and private methods are never visible so it is a contradiction in terms.
An interface is intended to represent an abstraction that a user (software) uses. Protected via child/parent represents a usage that is restricted to a child from a parent. The child can already see the parent so there is no point in having an abstraction for the child. And it would probably be unwise to limit a child by such an abstraction.
Protected via the package and interfaces is more contentious as to why it is not allowed. There are those that argue that this should be allowed so that a package can use interfaces but restrict them to the package. To me this seems like a minor point given that most interfaces will probably represent an abstraction to other packages and not within a single package. This applies specifically to default access as well.

Interface Method

Hi experts,
I have the following scenario:
Component A opens, in a modal window, the component B.
When I do something in B, it's closed and I return to A.
There, I need read data from B (which is closed at the moment), to do something in A.
Anybody knows how can I do it?
I tried with external context mapping, but It doesn't work...
Could it be done with interface methods?
Thanks in advance!
Lucas

Hi Padmam,
Thank you for your reply too, but I'm having problems with your solution.
I have created an interface Node in Component A, and I have created the mapping in the component usages of the component B.
When I run component A, it gives me an error. I supose that it is rise by this Interface Node.
This error is solved when I check out the property "Input Element (Ext)" of Interface Node, but without this property, I can't do the External Mapping...
Could you correct me if I'm wrong?
Thanks in advance!

Question when i am in web dynpro interface method trying to find code

Hello guys,
I am in an event handler and i see this logic wd_this->mo_dodm_srchbidder_c->add_selected_bidder(). When i double click on the add selected bidder it takes me to the method inside interface /sapsrm/IF_CLL_DODM_BIDDER. So when i double click on the method it takes me nowhere.
My question is what do i have to do or where do i go to see the code for add_selected_bidder? thank you.

I think, you have visited to the definition of the interface method and not the implementation of the method.
You have instantiated the wd_this->mo_dodm_srchbidder_c some where, may be in the wd domodifyview. Find that out where the implementation happens.
I believe when you double click the method in editor ask for to go to definition or implementation.

Overriding Interface methods via JNI

Hello,
How we can override Interface methods via JNI?
For example:
At HelloWorldSwing example:
http://download.oracle.com/javase/tutorial/uiswing/examples/start/HelloWorldSwingProject/src/start/HelloWorldSwing.java
I've written anonymous Interface as:
import javax.swing.*;
public class HelloWorldSwing1 {
     * Create the GUI and show it. For thread safety,
     * this method should be invoked from the
     * event-dispatching thread.
    private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame frame = new JFrame("HelloWorldSwing");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //Add the ubiquitous "Hello World" label.
        JLabel label = new JLabel("Hello World");
        frame.getContentPane().add(label);
        //Display the window.
        frame.pack();
        frame.setVisible(true);
    static Runnable runnableObject = new Runnable() {
         public void run() {
              createAndShowGUI();
   public static void main(String[] args) {
         //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        SwingUtilities.invokeLater(runnableObject);
}via JNI functions(http://download.oracle.com/javase/1.4.2/docs/guide/jni/spec/functions.html) we cannot override Runnable Interface's run method? Can we?
Only:
RunnableClass's value isn't null with given example at below. FindClass finds the Runnable Interface.
jclass RunnableClass;
RunnableClass = (*env)->FindClass(env,"java/lang/Runnable");
if( RunnableClass == NULL ) {
    printf("can't find class Runnable\n");
    exit (-1);
}But How can we override Runnable class's run method?
Thanks in Advance

The only way you can override a method in Java is by defining a class that does so, either statically or as an anonymous inner class. You can't do either of those things in JNI. Ergo you cannot do what you are asking about.

Class/Interface/Methods

Hi All,
I'm trying to understand the concept behind abap class/interface/methods.
1. Is it mandatory to have an interface in every class?
2. Once a class is created is it right to define methods as static and public and use them without reference to the interface?
Any help appreciated.
Meghna

hi meghna,
interfaces in ABAP Objects play the same role as classes. Just like classes, interfaces are object types that reside in the namespace of all types. While a class describes all aspects of a class, an interface only describes a partial aspect
The syntax for declaring a local interface is:
INTERFACE intf.
   DATA ...
   CLASS-DATA ...
   METHODS ...
   CLASS-METHODS ...
ENDINTERFACE.
Basically, the declaration of an interface corresponds to the declaration part of a class, where instead of CLASSu2014ENDCLASS, you simply use INTERFACEu2014ENDINTERFACE. Interfaces can contain exactly the same components as classes. Unlike classes, however, interfaces don't need to be divided into different visibility sections because interface components are always integrated in the public visibility section of classes.
i dont want to confuse you .
please go to the below link to know more about... interface and classes.
