Wda: call method from a component interface definition (cid)

hello,
I created the following scenario:
- I have a Main-component "m"
- "L" is a component interface definition (cid) which force both cid-L-implementating components "L1" and "L2" to extend and fill the method "set_COMP_USAGES()".
- I have other cid´s (A-C) too
- at runtime only one of the components "L1" or "L2" is created and the mother-component M holds component-usages (ref to) of the chosen variants of A-C and L as an attribute in the component-controller of m.
now my problem: my aim is to call a method in m at runtime which is defined at designtime in my cid L (set_COMP_USAGES() )and decided at runtime which variant of this method is chosen (the one from L1 or L2). in this method the references of comp_usages other cid´s should be passed to L1 or L2.
or short: how can I call a method from a cid-implementating component at runtime via a IF_WD_COMPONENT_USAGE reference (ref to) to this component?

I got the solution:
data: L_INTF_CONTROLLER         type ref to ZIWCI_Z_ITF_CID_L.
L_INTF_CONTROLLER ?= wd_this->COMPONENT_USAGE_L->GET_INTERFACE_CONTROLLER( ).
CALL METHOD l_intf_controller->set_comp_usages
    EXPORTING
      comp_usage_a = wd_this->COMPONENT_USAGE_a
      comp_usage_b = wd_this->COMPONENT_USAGE_b
      comp_usage_c = wd_this->COMPONENT_USAGE_c.

WebDynpro Method from a Class Interface?

Is possible to call a webdynpro method from a class interface that is register in the WDDOINIT of the same WEBDYNPRO component?
I register my custom webdynpro screen into FPM_OIF_COMPONENT, now when I execute a FPM action my WebDynpro receives the action but ofcourse WDDOINIT doesn't get triggered again. I need to call my webdynpro code in the class interface so I can update my custom screen.
SAP does that in their standard screen, Can I do that?

As Matt pointed out, your questions indicate that you should start from the basics, then as your knowledge enlarges, go and familarize with more advanced concepts of ABAP Objects. Once you feel a bit comfortable with that, go for BADIs and read a bit about that too.
In my opinion the best start is to read some book, which covers most of ABAP OO concepts. Personally I would recommend [ABAP Objects: ABAP Programming in SAP NetWeaver|http://www.sap-press.com/product.cfm?account=&product=H1934] as I like this author and had his previous book. This would give you strong foundations of what is going on here. Eventually you will often want to refresh some concepts so you have everything you need in one spot (book).
Of course if want to save some money, simply look for articles/blogs/wikis in SDN or search in Google. There are plenty of these.
For start I suggest these series of videoblogs [Basic ABAP OO eLearnings|http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3414800)ID1160600550DB10016261778120999663End?blog=/pub/wlg/15408]
This will give you rough idea how the OO design should be done.

Plug type definition in Component Interface Definition

Hi,
in my Component Interface Definition I need to define a startup plug. Upon plug creation, however, there's no prompt regarding plug type. Moreover I cannot see the plug type in the IDE, as I was used in interface view controllers.
Editing the plug does not allow any change at all, specifically no change to the plug type.
As of now, all my plugs are standard plugs (I know that from errors when building implementing components).
Can anyone please help?
Thanks, Vincenzo

Call methods from view controller to another (enhanced) view controller!

Dear All,
Is it possible to use/call methods from view controller to another (enhanced) view controller? Iu2019ve created a view using enhancement in standard WD component. I would like to call one method from standard view controller in the enhanced view controller.
Is it possible to include text symbols as enhancement in standard class?
u2026Naddy

Hi,
If you have just enhanced an existing view then you can call the standard methods in one of the new methods which you will create as part of enhancement.
If you have created a totally new view using enhancement framework option ( Create as Enhancement ) then in this new view you won't be able to use existing methods in other view as a view controller is private in nature. So all the view attributes, context nodes and methods are Private to that view only.
Regarding text elements, I guess adding a new text element is just a table entry in text table and is therefore not recorded as enhancement.( Not very sure about this, need to double check )

Is it possible to call methods from another class from within an abstract c

Is it possible to call methods from another class from within an abstract class ?

I found an example in teh JDK 131 JFC that may help you. I t is using swing interface and JTable
If you can not use Swing, then you may want to do digging or try out with the idea presented here in example 3
Notice that one should refine the abstract table model and you may want to create a method for something like
public Object getValuesAtRow(int row) { return data[row;}
to give the desired row and leave the method for
getValuesAt alone for getting valued of particaular row and column.
So Once you got the seelcted row index, idxSelctd, from your table
you can get the row or set the row in your table model
public TableExample3() {
JFrame frame = new JFrame("Table");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}});
// Take the dummy data from SwingSet.
final String[] names = {"First Name", "Last Name", "Favorite Color",
"Favorite Number", "Vegetarian"};
final Object[][] data = {
     {"Mark", "Andrews", "Red", new Integer(2), new Boolean(true)},
     {"Tom", "Ball", "Blue", new Integer(99), new Boolean(false)},
     {"Alan", "Chung", "Green", new Integer(838), new Boolean(false)},
     {"Jeff", "Dinkins", "Turquois", new Integer(8), new Boolean(true)},
     {"Amy", "Fowler", "Yellow", new Integer(3), new Boolean(false)},
     {"Brian", "Gerhold", "Green", new Integer(0), new Boolean(false)},

     {"Hans", "Muller", "Maroon", new Integer(5), new Boolean(false)},

Is Two Classes that call methods from each other possible?

I have a class lets call it
gui and it has a method called addMessage that appends a string onto a text field
i also have a method called JNIinterface that has a method called
sendAlong Takes a string and sends it along which does alot of stuff
K the gui also has a text field and when a button is pushed it needs to call sendAlong
the JNIinterface randomly recieves messages and when it does it has to call AddMessage so they can be displayed
any way to do this??

Is Two Classes that call methods from each other possible?Do you mean like this?
   class A
     static void doB() { B.fromA(); }
     static void fromB() {}
   class B
     static void doA() { A.fromB(); }
     static void fromA() {}
.I doubt there is anyway to do exactly that. You can use an interface however.
   Interface IB
     void fromA();
   class A
     IB b;
     A(IB instance) {b = instance;}
     void doB() { b.fromA(); }
     void fromB() {}
   class B implements IB
     static void doA() { A.fromB(); }
     void fromA() {}
.Note that you might want to re-examine your design if you have circular references. There is probably something wrong with it.

How to call methods from within run()

Seems like this must be a common question, but I cannot for the life of me, find the appropriate topic. So apologies ahead of time if this is a repeat.
I have code like the following:
public class MainClass implements Runnable {
public static void main(String args[]) {
Thread t = new Thread(new MainClass());
t.start();
public void run() {
if (condition)
doSomethingIntensive();
else
doSomethingElseIntensive();
System.out.println("I want this to print ONLY AFTER the method call finishes, but I'm printed before either 'Intensive' method call completes.");
private void doSomethingIntensive() {
System.out.println("I'm never printed because run() ends before execution gets here.");
return;
private void doSomethingElseIntensive() {
System.out.println("I'm never printed because run() ends before execution gets here.");
return;
}Question: how do you call methods from within run() and still have it be sequential execution? It seems that a method call within run() creates a new thread just for the method. BUT, this isn't true, because the Thread.currentThread().getName() names are the same instead run() and the "intensive" methods. So, it's not like I can pause one until the method completes because they're the same thread! (I've tried this.)
So, moral of the story, is there no breaking down a thread's execution into methods? Does all your thread code have to be within the run() method, even if it's 1000 lines? Seems like this wouldn't be the case, but can't get it to work otherwise.
Thanks all!!!

I (think I) understand the basics.. what I'm confused
about is whether the methods are synced on the class
type or a class instance?The short answer is; the instance for non-static methods, and the class for static methods, although it would be more accurate to say against the instance of the Class for static methods.
The locking associated with the "sychronized" keyword is all based around an entity called a "monitor". Whenever a thread wants to enter a synchronized method or block, if it doesn't already "own" the monitor, it will try to take it. If the monitor is owned by another thread, then the current thread will block until the other thread releases the monitor. Once the synchronized block is complete, the monitor is released by the thread that owns it.
So your question boils down to; where does this monitor come from? Every instance of every Object has a monitor associated with it, and any synchronized method or synchonized block is going to take the monitor associated with the instance. The following:
synchronized void myMethod() {...is equivalent to:
void myMethod() {
    synchronized(this) {
...Keep in mind, though, that every Class has an instance too. You can call "this.getClass()" to get that instance, or you can get the instance for a specific class, say String, with "String.class". Whenever you declare a static method as synchronized, or put a synchronized block inside a static method, the monitor taken will be the one associated with the instance of the class in which the method was declared. In other words this:
public class Foo {
    synchronized static void myMethod() {...is equivalent to:
public class Foo{
    static void myMethod() {
      synchronized(Foo.class) {...The problem here is that the instance of the Foo class is being locked. If we declare a subclass of Foo, and then declare a synchronized static method in the subclass, it will lock on the subclass and not on Foo. This is OK, but you have to be aware of it. If you try to declare a static resource of some sort inside Foo, it's best to make it private instead of protected, because subclasses can't really lock on the parent class (well, at least, not without doing something ugly like "synchronized(Foo.class)", which isn't terribly maintainable).
Doing something like "synchronized(this.getClass())" is a really bad idea. Each subclass is going to take a different monitor, so you can have as many threads in your synchronized block as you have subclasses, and I can't think of a time I'd want that.
There's also another, equivalent aproach you can take, if this makes more sense to you:
static final Object lock = new Object();
void myMethod() {
    synchronized(lock) {
      // Stuff in here is synchronized against the lock's monitor
}This will take the monitor of the instance referenced by "lock". Since lock is a static variable, only one thread at a time will be able to get into myMethod(), even if the threads are calling into different instances.

Calling methods from inside a tag using jsp 2.0

My searching has led me to believe that you cannot call methods from in the jsp 2.0 tags. Is this correct? Here is what I am trying to do.
I have an object that keeps track of various ui information (i.e. tab order, whether or not to stripe the current row and stuff like that). I am trying out the new (to me) jsp tag libraries like so:
jsp page:
<jsp:useBean id="rowState" class="com.mypackage.beans.RowState" />
<ivrow:string rowState="${rowState}" />my string tag:
<%@ attribute type="com.mypackage.beans.RowState" name="rowState" required="true" %>
<c:choose>
     <c:when test="${rowState.stripeToggle}">
          <tr class="ivstripe">
     </c:when>
     <c:otherwise>
          <tr>
     </c:otherwise>
</c:choose>I can access the getter method jst fine. It tells me wether or not to have a white row or a gray row. Now I want to toggle the state of my object but I get the following errors when I try this ${rowState.toggle()}:
org.apache.jasper.JasperException: /WEB-INF/tags/ivrow/string.tag(81,2) The function toggle must be used with a prefix when a default namespace is not specified
Question 1:
Searching on this I found some sites that seemed to say you can't call methods inside tag files...is this true?...how should I do this then? I tried pulling the object out of the pageContext like this:
<%@ page import="com.xactsites.iv.beans.*" %>
<%
RowState rowState = (RowState)pageContext.getAttribute("rowState");
%>I get the following error for this:
Generated servlet error:
RowState cannot be resolved to a type
Question 2:
How come java can't find RowState. I seem to recall in my searching reading that page directives aren't allowed in tag files...is this true? How do I import files then?
I realized that these are probably newbie questions so please be kind, I am new to this and still learning. Any responses are welcome...including links to good resources for learning more.

You are correct in that JSTL can only call getter/setter methods, and can call methods outside of those. In particular no methods with parameters.
You could do a couple of things though some of them might be against the "rules"
1 - Whenever you call isStripeToggle() you could "toggle" it as a side effect. Not really a "clean" solution, but if documented that you call it only once for each iteration would work quite nicely I think.
2 - Write the "toggle" method following the getter/setter pattern so that you could invoke it from JSTL.
ie public String getToggle(){
    toggle = !toggle;
    return "";
}Again its a bit of a hack, but you wouldn't be reusing the isStriptToggle() method in this way
The way I normally approach this is using a counter for the loop I am in.
Mostly when you are iterating on a JSP page you are using a <c:forEach> tag or similar which has a varStatus attribute.
<table>
<c:forEach var="row" items="${listOfThings}" varStatus="status">
<tr class="${status.index % 2 == 0 ? 'evenRow' : 'oddRow'}">
    <td>${status.index}></td>
    <td>${row.name}</td>
</tr>
</c:forEach>

Cross-component: Call method of using component from within used component?

Hi,
I began diving into cross-component programming.
Meanwhile after having digged into some scenarios some questions came up to my mind that I am not able to answer myself. I would appreciate your help here!
Say we have to components. Comp A uses Comp B (hence, B is a component usage in A)
1) How to make them communicate not on a data level (via context binding) but on a process level, thus...
a) can I call A's method from within B? How is the approach on a general level? - as B can be used from totally different components (like A, A1, A2 ...)
b) perhaps the only way to do this is by firing events? If so, how can I react in A when an event in B (marked as interface event) gets fired? As it seems they do not get registered within A directly...
I guess the question seems to be a bit tricky. Nevertheless, I think there will be plenty of you out there who used to asked them the same questions before and came up with an approach. Would be nice to hear from you.
Best wishes,
Marc @sap1

Hi,
thanks for your reply!
Indeed, I think the nature of WDA would be just to somehow map the context from the used component to the other back and forth.
Nevertheless, what if I would like to invoke a method of the using component from inside the used component.
One sample for this requirement could be e.g.:
Component B offers a tree item and a send/verify button.
Component A uses B and has some restraints regarding what the selection should look like.
The user taps the button in B (at runtime in the view container of A), the context gets updated in A and B and in Component A the verifyWithOwnConstraints() method gets called (through B).
Thanks again,
Marc

How to Call Methods of one component into another Component

Hi Manas Thanks for your fast reply,
My question is, for example we have wd_comp_controller or wd_this objects to call methods of view from view and comp controller right.. like this we have any methods to call used component methods? if yes can u please give me the objects syntax?...

Calling RFC from view/component controller

I've got a model node in the component controller's context which is mapped to a node in a view controller. Now, when binding the model's input node with an array and executing the RFC from within an event handler in the view controller, everything goes just fine.
Now, I want to put this functionality in the component controller, so I created a method there, copied the code and call it from the view controller's event handler. When the RFC is called, the input table always contains just 1 element, of which the fields are all initial.
Any thoughts on what might be going on here?

Hi friend,
I too faced the problem what you faced.
Near to it.
Ill explain you .
YOu have your model node.
1st you will map that to component controller And from there to view controller.
After that you will bind the elements in this node to some elements in your view after that .
For example
Model class name:-Lok_model.
In the DOINIT method:-
write this code.
Lok_model k = new Lok_model(); wdContext.nodeLok_model().bind(k);
Suppose you have a button in the onaction you write this code.
wdContext.nodeLok_model().currentLok_modelElement().modelObject().get_details();
Ill expalin you about this statement Lok_model() is the node in my view which is mapped from the model and by using that i am calling the method get_details() which is in my model class Lok_model.By this data will be automatically populated into the view elements which are being binded to the model attributes.
Hope this helps you,
Lokesh

        g2.fillOval(x-SPOT_DIAM/2, y-SPOT_DIAM/2, SPOT_DIAM, SPOT_DIAM);
}in another class A (the main class where i run everything) i created a new instance of dice and added it onto a JPanel.Also a JButton is created called roll, which i added a actionListener.........rollButton.addActionListener(B); (B is instance of class B)
In Class B in implements actionlistener and when the roll button is clicked it should call "roll()" from Dice class
Dice d = new Dice();
d.roll();
it works but it does not repaint the graphics for the dice? the roll method will get a random number but then it will call the method to repaint()???

One way:
class Flintstone
    private String name;
    public Flintstone(String name)
        this.name = name;
    public String toString()
        return name;
    public static void useFlintstoneWithReference(Flintstone fu2)
        System.out.println(fu2);
    public static void useFlintstoneWithOutReference()
        Flintstone barney = new Flintstone("Barney");
        System.out.println(barney);
    public static void main(String[] args)
        Flintstone fred = new Flintstone("Fred");
        useFlintstoneWithReference(fred); // fred's the reference I"m passing to the method
        useFlintstoneWithOutReference();
{code}
can also be done with action listener
{code}    private class MyActionListener implements ActionListener
        private Flintstone flintstone;
        public MyActionListener(Flintstone flintstone)
            this.flintstone = flintstone;
        public void actionPerformed(ActionEvent arg0)
            //do whatever using flinstone
            System.out.println(flintstone);

You have to go through the root application module like so:
((MyAppModuleAMImpl)this.getDBTransaction().getRootApplicationModule()).filtrarMatricula(codigo);Hope this helps.
