Question: Call OData Connector methods from View JS or XML

Hello Experts,
We are working on a small proof of concept wherein we would like search the list of employees based on the employee code. We are trying to connect to success factors (SF) backend here using OData. The view.js file is developed using SAP UI5. Now we are trying to call backend method which should connect to SF from JS in the event - 'on click' of 'search' button.
We have referred the benefits sample application already but the search in this is more of filtering rather connecting to backend on the fly. It prefetching the employees list and filtering on the results table. So, we could not get much of help here.
We know this is a basic stuff but as we are new to this framework, any references or pointers on this topic would be of great help. Appreciate your support. Thanks in advance.
Regards,

you just have to instantiate an oData model with your backend url,

Call component controller method from view

Hi
I have created an action in view Thus its event handler is "OnActionDoSomething()"
And, I have a method in component controller "MethodSaySomething()".
Now, how can I call MethodSaySomething() from OnActionDoSomething().
OnActionDoSomething()
// Call MethodSaySomething() defined in component controller
Thanks

Hi,
To access the methods present in component controller from View , first u need to add the component controller as the required controller.
open the view controller --> switch to propertues tab --> add the component controller as required controller(click add controller).
Now in your action handler , write this below code to add the method:
wdThis.wdGet<COmponent Controller>().MethodSaySomething();
Hope it helps
Thanks and Regards,

How to call a custom controller method from view

Hi,
I ve created a simple web service and consumed it in a model. Mapped the input & output parameters to custom controller context which in turn mapped to component controller's context which in turn to view's contexts.
How to call a custom controller method from view?
Please explain the syntax.
Regards,
Manoj.

Hi Patralekha,
Give some idea for the below scenario:
I ve created a simple web service and consumed it in a model. What I did was
1) for the input parameters, mapped the node from view->custom controller->model
2)for the output parameter, mapping from model->custom controller->view.
It works fine.
But I don't want to access model nodes directly, rather I want to set the input param in somewhere else (like custom controller) before calling the appropriate method, same for the response also.
Share me your thoughts.
Regards,
Manoj.

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 )

i don't know why this is happening i got declare the method recibeBuffer in my SocketC.java class, but doesn;t work can anyone help me?
PD: sorry for my bad english i'm from Venezuela

Next time please paste your code between [code] tags with the code button just above the edit message area.
To answer your question, you wrote the wrong method signature. It should be:jmethodID mmid = env->GetMethodID(cls, "recibeBuffer", "()V");Regards

How to call a bean method from javascript event

How to call a set method from within a constructor

Hello,
I want to be able to call a set method from within a Scanner, to be used as the argument to pass to the Scanner (from a source file). Here's what i tried:
private void openFiles()
        input = new Scanner( setSource );
    and here is the set method:
public String setSource( String in )
        source = in;
        return source;
    }obviously there will be more code in this method but i'm trying to tackle one problem at a time. Thanks in advance..

The "String in" declaration says: "Nobody may ever invoke setSource() without specifying a certain String. The content of the String is known at run-time only."
In no place in your code you say the compiler: "I want the 'in' variable (actually, parameter) of method setSource() to contain the first arg which is passed to the application".
This is exactly the same mechanism allowing you to write "new Scanner" with something inside the two parentheses.

Getting error while calling ejb business methods from servlet

Hi
Iam getting error when i try to call a ejb method from servlet.Error is
"com.netscape.server.eb.UncheckedException: unchecked exception nested exception is:java.lang.NullPointerException".
I build the application and deployed it successfully.Iam using IAS 6.O with windows NT 4.0.
This is just a method which takes values from database and return as an array of bean to servlet.
Any help on this.Thanks Shank

Hi
I was using the session bean.Your suggestion helped me a lot.Perfect.
I debug my program and found that from ejbCreate()exception is getting.
I was getting the datasource object thro ejb create() initialisation.
Somehow the look up jndi which i mentioned was not interpretting from ejb-jar.xml ias-ejb-jar.xml and datasource ref .Due to this iam getting jndi Namenotfound exception which in turns to null pointer as datasource is getting null.
when i hardcoded in the ejb the the jndi name for datasource it is working fine.Bit worried all the existing ejbs working with the xml referenced datasource and jndi,but when i added a new ejb with same properties it is failing to get the jndi name.
Piece of code from ias-ejb-jar.xml
<resource-ref>
          <res-ref-name>myDataSource</res-ref-name>
          <jndi-name>jdbc/nb/myData</jndi-name>
</resource-ref>
Piece of code from ejb-jar.xml
<resource-ref>
          <res-ref-name>myDataSource</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>

Calling a service method from a DataAction

Hello!
I'm trying to call a service method from a DataAction, cobbling ideas from the Oracle JDeveloper 10g Handbook and the Oracle ADF Data Binding Primer.
I have created a service method and exposed it using the client interface node of the application module editor. It is called "process()" and it now appears in the data control palette under MyAppDataControl->Operations (just above the built-in action bindings Commit and Rollback). As part of this procedure, I modified MyAppImpl.java and put the process() method there.
I don't want to call process() by dragging and dropping it onto a Data Action because depending on the outcome, I want to branch to different pages. process() returns an int that will tell me where to branch. Thus, I am trying to call it from an overridden invokeCustomMethod() method of the lifecycle of a DataAction, where I can get the int, create a new ActionForward, and set it in the DataActionContext. (If I'm barking up the wrong tree, let me know!)
So, I need to call MyAppImpl.process() from within the invokeCustomMethod() method of my DataAction. Looking at the class declaration, I noticed that it extends ApplicationModuleImpl. I figure that, if I can get the ApplicationModule, I can cast it to MyAppImpl and call the process() method. Unfortunately, that doesn't work. When I got the application module, I checked the class and it's oracle.jbo.common.ws.WSApplicationModuleImpl. I tried casting it and got a class cast exception.
Here's the code I'm using:
protected void invokeCustomMethod(DataActionContext actionContext) {
BindingContext ctx = actionContext.getBindingContext();
DCDataControl dc = ctx.findDataControl("MyAppDataControl");
log.debug("invokeCustomMethod(): dc.getClass().getName()=" + dc.getClass().getName()); // result is: oracle.jbo.uicli.binding.JUApplication
ApplicationModule am = null;
MyAppImpl myAppImpl = null;
int processResult = 0;
if (dc instanceof DCJboDataControl) { // this is true
am = dc.getApplicationModule();
log.debug("invokeCustomMethod(): am.getClass().getName()=" + am.getClass().getName()); // result is: oracle.jbo.common.ws.WSApplicaitonModuleImpl
if (am instanceof ApplicationModuleImpl) { // this is false
log.debug("invokeCustomMethod(): am is an instanceof ApplicationModuleImpl.");
if (am instanceof MyAppImpl) { // this is false
log.debug("invokeCustomMethod(): am is an instanceof MyAppImpl.");
processResult = ((MyAppImpl)am).process();
log.debug("invokeCustomMethod(): processResult=" + processResult);
super.invokeCustomMethod(actionContext);
What am I doing wrong? Can anyone explain the different class hierarchies and why my application module isn't the class I'm expecting?
Thanks,
-Anthony Carlos

Georg,
it was in the javadoc of oracle.adf.model.binding.DCBindingContainer
http://www.oracle.com/webapps/online-help/jdeveloper/10.1.2/state/content/vtTopicFile.bc4jjavadoc36%7Crt%7Coracle%7Cadf%7Cmodel%7Cbinding%7CDCBindingContainer%7Ehtml/navId.4/navSetId._/
However, I see it's not the case in other sub-classes of JboAbstractMap like DCControlBinding and DCDataControl.
Weird... I'm keeping you informed if I find more information.

Didier.

Call enhancement class method from Bus. workflow task

Hi all,
I recently enhanced a global class from SAP (add a new method). Now I would like to call it from a workflow task (ABAP Class object used in the task). So it seems that only "native" methods from the class itself can be selected for the object method of the task.
Same issue if I try to call it via secondary methods options...
Last idea I have before the repair is: retrieve the instance saved into the WF container via a custom class interfacing IF_IFS_SWF_CONTAINER_EXIT (program exit) and call the enhanced method from the method proposed in this interface.
Maybe someone had the same issue? Anyone could help or propose solution?
Many thanks in advance for your help,
KR,
Olivier

I think it might qualify for an OSS message.
There was simmilar note for BADIs which was corrected: https://service.sap.com/sap/support/notes/1156392

How to call jpf controller method from javascript

Can any one help me how to call pageflow controller method from JavaScript.\
Thanks.

Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
document.getElementById("batchForm").submit;
2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
document.getElementById("ACTION_NAME").value = "UPDATE";
document.getElementById("batchForm").submit.
Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
This entire lines of code should do what we want.
<netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>
<netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
<c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
<%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
<netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
</c:forEach>
</netui:select>
See if you can build along those above lines of code. Any other simpler approches are highly welcome.
Thanks

How to call Custom or Component Controller methods from View Controller

Hy Guys,
how do I call Custom Controller or Component controller methods from a View or Context Controlller?
thanks in advance
Jürgen

Hi Juergen
Yes it is possible, pls follow the below approach to access the component controller in context node class
1) since the standard component controller class is protect variable , declare a variable of type component controller in your controller class.
say for example the public variable you declared is g_comp_controller
2) now redefine the controller class method WD_CREATE_CONTEXT and add the below lines of code
   g_comp_controller ?= me->comp_controller.
3) go to context node class (CNXX) there declare the varaible which of type controller class (IMPL) as public variable, for example g_owner
4) redefine the method IF_BSP_MODEL~INIT and write the below code
     CALL METHOD super->if_bsp_model~init
    EXPORTING
      id    = id
      owner = owner.
g_owner ?= owner.
5) now the variable   g_owner that is declared in (CNXX)   contains reference to your controller class
6) in on_new_focus method access your component controller in the below manner and access the entities also.
DATA: lv_owner                    TYPE REF TO xxxxx_impl, " Implementation class
             lr_comp_cont                TYPE REF TO xxxx_bspwdcomponen_impl, " component controller class
             lv_entity type ref to cl_crm_bol_entity.
lv_owner ?= g_owner.
lr_comp_cont    ?= lv_owner->g_comp_controller.
IF lr_comp_cont IS BOUND.
   lv_entity ?= lr_comp_cont->typed_context->mdfcampaign->collection_wrapper->get_current( ).
now lv_entity contains the value of component controller context node.
Thanks & Regards
Raj
