Calling a method in Class from webdynpro

Hi All,
I have to perform some action when i click the button created in my webdynpro screen.
However I must not write the code for the button action inside the button event. But I have to create a class and inside the class i have to create the method for this button event.
Can anyone tell me how to call a method in a class created in SE24 from webdynpro on clicking the button.
Thanks in advance.

hi..
When you want to perform some action after clicking a Button, then you have to write the code only in 'Events' - 'On Action' event. From your question, i assume that, you wanna use Assistance class in your webdynpro so as to increase better performance. Here is the link which will guide yuo with screen shot for using assistance class in WD-ABAP.

Calling a method in view from component controller?

Hi,
Is it posible to call a method that is defined in the Component Controller in the View?
If it is posible please give some sample code how to call the method?
Regards,
Padmalatha.K

Padmalatha, all the methods defined in a controller from 'Methods' tab are instance methods. An instance method defined in a component controller is callable from any view controller that holds a reference to the component controller.
Defining methods between the tags
//@@begin others
//@@end
is useful if you want to declare static methods.

How to call a method in bean from application module Impl?

i have to call a method which is in a bean from AppmoduleImpl class. Is it possible ?

The model layer should never depend on a specific view layer - this breaks reusability.
What you need to do is expose a service method on your AM. Then your view can call this method and pass a parameter into the model layer.

How to call a method in Viewimpl from transient attributes value

Hai,
I have a method in ViewImpl say validate().I need to call this method from an transient attributes value where value type is expression.i used adf.object.validate() but its not working.
Can any one help me
Thanks in advance

Hai,
Jabr i read these in a pdf where it explains about Introduction to Groovy support in JDeveloper and Oracle ADF 11g
Referencing custom methods in the EntityImpl class
If you have defined a method in your EntityImpl class, then this can be called as part of your
expression for an attribute default:
adf.object.getDefaultSalaryForGrade()
Unlike when referencing an attribute of the entity object, which can be done by simply
referencing the attribute name, when referencing a method, you are required to prefix the
method name with adf.object.
So is there a way?
regards

Calling a Method in Bean from JSP

Is there a defined jsp tag for calling a method in a Bean? Right now, in a bean named "bean", I would use: <% bean.doSomething(); %>. Is there a tag for this?

I've wondered this too, the getProperty and setProperty tags only allow you call setters and getters. What if you've got a method called doSomething()?

Error when I call a method of AppModule from a backing bean.

I use Jdeveloper 10.1.3.0.3 EA.
In my application I have created ApplModule and UsrView(for my table USR).
I have a login page (login.jsp and the backing login.java) with 2 fields userName and password and an ADF Faces Core command button (cmdCheckPass) and the method cmdCheckPass _action() for the click event .
The problem is that I cant call method testPassword(userName, password) which is written in AppModule. (I get error:
javax.faces.FacesException: #{backing_login.cmdCheckPass_action}: javax.faces.el.EvaluationException: java.lang.NullPointerException) from line:
answer = app.testPass(st1,st2);
The code is as follows:
public String cmdCheckPass_action() {
String answer="";
String mes = "";
String st1=this.getInputText1().getValue().toString();
String st2=this.getInputText2().getValue().toString();
AppModuleImpl app = new AppModuleImpl();
answer = app.testPass(st1,st2);
if (answer == "OK") {
return "toMain";
} else {
answer = "";
mes="Invalid username, password !!!";
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(mes));
return answer;}
I dont know if theoretically is right to call, from a backing bean, a custom method of AppModule.
Can I have any help on this?
Thanks in advance,
Panos

Some quick ideas:
Is the clip the same NTSC/PAL standard as the project you are importing it to?
Have you tried to rename the offending clip (do NOT rename any clips inside the iMovie /Media folder!!).
How much free space do you have on the iMovie project volume -- what is the size of the imported clip?

Calling a method in AbstractPortalComponent from JSP

Hi,
I have an abstract portal component with 2 methods:
1. doContent - in this, I specify the name of the jsp to be included in the response - umlogonPage, and am setting a portal event named 'fireCRMRFC'.
2. dofireCRMRFC - in this, I specify the code to connect to the backend crm and get back some value.
In my umLogonPage.jsp, how can I trigger the method 'doFireCRMRFC'? Is it possible at all?
Thanks
OJ

Hi Praveen
I understand you partially...I have implemented this:
public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
          IResource jspResource = request.getResource("jsp", "/umLogonPage.jsp");
          response.include(request, jspResource);
          IPortalComponentURI rfcURI = request.createPortalComponentURI();
          rfcURI.setPortalRequestEvent(request.createRequestEvent("fireCRMRFC"));
and
public void dofireCRMRFC(IPortalComponentRequest portalReq, IEvent event){
<Connectivity code to backend.>
And I read in another thread and help site that I can raise an event from the jsp to this method (maybe through the doCOntent), but it said this is possible. Can you give me an example of a code that I would have to use in my jsp?
I am trying to understand how this works so I really appreciate your willingness to help.
Thanks

Calling a method in AbstractPortalComponent from JSP without htmlb

Hi,
I am trying to trigger an event in a java method in an AbstractPortalComponent from a jsp.
The event is caught in method doContent:
IPageContext myContext = PageContextFactory.createPageContext(request, response);
Event lastEvent = myContext.getCurrentEvent();
if ((lastEvent != null) && (lastEvent.getComponentName().equals("Compute"))) {
response.write("Compute");
The problem is that I cannot trigger it from my jsp. In the jsp is used:
<%
IPortalComponentURI uri = componentRequest.createPortalComponentURI();
uri.setPortalRequestEvent(componentRequest.createRequestEvent("Compute"));
String linkEvent = uri.toString();
%>
and
<.a href="<%=linkEvent%>">click</a.>
(i put some dots because otherwise the editor sees it as html)
Please help.
Raymond

Hi Praveen,
It still does not work. presentEvent is null.
In line: if (null != event && "Compute".equalsIgnoreCase(presentEvent.getAction())) you wrote "event" Shouldn't that be presentEvent. I changed it to presentEvent.
I think the problem is in the jsp. It seems to me that the jsp is not sending a correct event.
Please keep in mind that I am not using htmlb in my jsp.

Call applet method with arguments from JavaScript

I have an applet with a method doSomething(int a, String b, double c), I want get a,b,c from threee text fields put into an HTML page, and pass them to the applet method. I've a very poor knowledge in JavaScript, how can I pass correctly the arguments without raise a CastException? It seems to me that JavaScript doesn't have int, String, double.....

Hi!
You can verify before you send the parameters to the applet
Something like that:
var result = parseInt (a);
if (result =NaN)
alert("Sorry not Int");
return false;
and after that you can send the parammeters to the applet that way:
document.yourApplet.Your_function_from_applet(result,..)
hope this help!

Call JavaScript method in FXML from java controller

I have fxml like
   <fx:root type="javafx.scene.Group" xmlns:fx="http://javafx.com/fxml">
    <fx:script>
        function applyState(oldState, newState)
    </fx:script>
    ....and controller to it.
The idea is to move some view logic to fxml file.
So, when I need to change some view state, I want to call applyState from java code.
The question is how to do it.
What I have found:
We can get
fxmlLoader.getNamespace().get("applyState")and receive sun.org.mozilla.javascript.internal.InterpretedFunction.
NetBeans see this class. But while building the project i have an error
error: package sun.org.mozilla.javascript.internal does not exist
But this class really exists in rt.jar in JRE.
After that I have stopped digging into this.
I suspect that using internal API is not a good idea to call this InterpretedFunction.
Can somebody suggest how can I make such an invocation?
Edited by: 940811 on Nov 19, 2012 11:21 PM

Until JavaFX doesn't expose the ScriptEngine instance of FXMLLoader, there's no way to communicate (Java <-> Javascript) with the <fx:script>.
But, if you want to rely on a hack, you can do this:
    private ScriptEngine extractScriptEngine(FXMLLoader loader) {
        try {
            Field fse = loader.getClass().getDeclaredField("scriptEngine");
            fse.setAccessible(true);
            return (ScriptEngine) fse.get(loader);
        } catch (IllegalAccessException | NoSuchFieldException | SecurityException ex) {
            Logger.getLogger(BrowserFXController.class.getName()).log(Level.SEVERE, null, ex);
        return null;
    }

Object created dynamically. how to call a method or interface from it

Hi Experts,
I've just created an abap proxy dynamically
   FIELD-SYMBOLS <ref> TYPE any.
    CREATE DATA dref TYPE REF TO
               (ld_class).
    ASSIGN dref->* TO <ref>.
    CREATE OBJECT <ref>
      TYPE
        (ld_class)
      EXPORTING
        logical_port_name =logicalport.
This runs OK
But I can't call an Interface of the object proxy that belongs to ld_class
ld_prot ?=   <ref>->if_proxy_basis~get_protocol( if_wsprotocol=>sequence ).
because the object <ref> is type any, it doesen't runs
This work' s fine
    MOVE <ref> ?TO proxy1.
    ld_prot ?= proxy->if_proxy_basis~get_protocol( if_wsprotocol=>sequence )
if proxy is explicity declarated like class proxy
But I don't want do it. I want do it dynamically to avoid write data declaration explicity
I think this is a problem for every data that must be declarated by the form TYPE REF TO
What must I do ?
thanks in advance.
