When to call a BAPI inputexecute method from webdynpro-java?

Hello... I'm a little concerned about a situation I'm having. The thing is that I'm trying to use the Bapi_Qualiprof_Change bapi with some test and hard coded data for a future application. It works fine if I fill the input profile_add table in the init() method of my view and then directly call the onActionModifyQualification method (inside the same init() where i filled the parameters).
On the contrary, if I change the code that intializes the data to the onActionModifyQualification or create an special method to initialize it wich is called later with an action button, then it doesn't work.
After many test I noticed that i have to call the bapi execute method right in the init... is there something I can do to fix it? or is it that i must do it in order to make it work?
I have my controller's context mapped to the bapi's model and the view context mapped to the controller's one.... is it good or do i have to build a similar structure to capture the parameters before and then copy the values into the controller's context??
Thanks a lot!!

Thanks for your answer, but it doesn't let me do that because wdModifyView is static. Therefore if 2 people are trying to use it, it's goning to be all mixed up, isn't it?
Anyway, what I really want is executing the bapi when I press the button (that's when it should call the action that calls the bapi). But it only works if I call the action in the init method.

Passing Parameters via Post Method from Webdynpro Java to a web application

Hello Experts,
I want to pass few parameters from a web dynpro application to an external web application.
In order to achieve this, I am referring to the below thread:
HTTP Post
As mentioned in the thread, I am trying to create an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.
But when I build my DC, I am getting the same error which most of the people in the thread have mentioned:
Controller XXXCompInterfaceView [Suspend]: Outbound plug (of type 'Suspend') 'Suspend' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'.
I am using SAP NetWeaver Developer Studio Version: 7.01.00
Kindly suggest if this is the NWDS version issue or is it something else that I am missing out.
Also, if it is the NWDS version issue please let me know the NWDS version that I can use to avoid this error.
Any other suggestion/alternative approach to pass the parameters via POST method from webdynpro java to an external web application apart from the one which is mentioned in the above thread is most welcome.
Thanks & Regards,
Anurag

Hi,
This is purely a java approach, even you can try this for your requirement.
There are two types of http calls synchronous call or Asynchronous call. So you have to choose the way to pass parameters in post method based on the http call.
if it is synchronous means, collect all the values from users/parameters using UI element eg: form and pass all the values via form to the next page is nothing but your web application url.
If it is Asynchronous means, write a http client in java and integrate the same with your custom code and you can find an option for sending parameters in post method.
here you go and find the way to implement Asynchronous scenario,

How do I call an Application Module method from a EntityImpl class?

Guys and Gals,
Using Studio Edition Version 11.1.1.3.0.
I've got a price update form, that when submitted, takes the part numbers and prices in the form and updates the corresponding Parts' price in the Parts table. Anytime this Parts view object's ReplacementPrice attribute is changed, an application module method needs to be called which updates a whole slew of related view objects. I know you can modify view objects via associations (How do I call an Application Module method from a ViewObjectImpl class? but that's not what I'm trying to do. These AppModuleImpl methods are the hub for all price updates, as many different operations may affect related pricing (base price lists, price buckets, etc) and hence, call the updatePartPricing(key) method.
For some reason, the below code does not call / run / activate the application module's method. The AppModuleDataControl exists and recordPartHistory(key) is registered and public. At runtime, the am.<method> code is simply ignored, and as a weird side-effect, I cannot navigate out of my current page flow.
public void setReplacementPrice(Number value)
    setAttributeInternal(REPLACEMENTPRICE, value);
    AppModuleImpl am = (AppModuleImpl)this.getDBTransaction().findApplicationModule("AppModuleDataControl");
    Key key = new Key(new Object[]
        { getPartNumber() });
    am.recordPartHistory(key); // AppModuleImpl method which records pricing history
    am.updatePartPricing(key); // AppModuleImpl method which updates a whole slew of related pricing tables
}Any ideas?

Thanks Timo.
Turns out the code provided was correct, but the AppModuleImpl method being called was not. A dependent ViewObject wasn't returning the row I was expecting. I then tried to perform some operations on that row, which in turn ... just stopped everything, but didn't give me an error.
It was the lack of the error that threw me off. I had never messed with calling an AppModuleImpl method from the EntityImpl so I assumed that's what was messing up.
You are correct. It is available from the ViewRow, but I thought it better to put it in the EntityImpl. This method will be called every time the replacement cost is modified. If I didn't put it in the EntityImpl, I'd have to remember to call it every time a replacement cost changed.

Calling custom Infotype method from Webdynpro Abap

Hi Experts,
I am working on an application where i need to call a method of a custom defined infotype.
I have done this -->
1. Create a custom infotype 9111
2. SAP creates a class of that infotype ZCL_HRPA_INFOTYPE_9111
3. Inside this method there are few inherited method which provide me functionality of insert , update , delete
i want to call methods IF_HRPA_INFTY_BL~MODIFY,
IF_HRPA_INFTY_BL~INSERT
However when i call these method from webdynpro abap this method does not work.
where as when i try to insert an entry using PA30 transaction it works.
Does anyone know why does this happen and what is the solution?
Regards,
Ashish Shah

Hi Ashish,
You need to create method inside your assistance class, the class your webdynpro component talks to.
Within the methods of Assistance class you will have to create instance of ZCL_HRPA_INFOTYPE_9111 and call its method IF_HRPA_INFTY_BL~INSERT passing the data.
Cheers

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 a view's method from Component Controller.

Hi
Is it possible to call a view's method from Component Controller.
Regards
Nikhil

Hi Tummuru,
I have created an event in Component Controller by the name toMenuView. Now I created a method in which this event is getting fired. Foll. is the code of the method.
public void fireToMenuView( )
wdComponentAPI.getMessageManager().reportSuccess("fireToMenuView");
wdThis.wdFireEventToMenuView();
Now I have created an event handler "handleToMenuView" in the MenuView and subscribed the event handler to the event in Component Controller.
The control is reaching to the fire event in component controller but not to the Event handler in view controller.
What am I missing.

How to call Apps Module Custom Method from Entity Object / View Object ?

Hi All,
I create a custom method in AppsModuleImpl.java. How can I call that custom method from a setter method on Entity Object / View Object ?
(I have tried to use Configuration.createRootApplicationModule(amDef,config); but it is not the correct way, is it? )
Below is my code :
The setter on MyEntityImpl.java :
public void setKodeprd(String value) {
setAttributeInternal(KODEPRD, value);
if (getProduct() != null) {
// CALL the getSalesPrice custom method from here, HOW ??
The Application Module custom method :
public Number getSalesPrice(String priceCode, String kodePrd) {
Number price = new Number(0);
String [] theKey = {priceCode, kodePrd};
Key priceKey = new Key(theKey) ;
ViewObject SalesPrice = getSalespricedView1();
Row[] salesPriceRow = SalesPrice.findByKey(priceKey, 1);
price = ((SalespricedViewRowImpl)salesPriceRow[0]).getPrice();
SalesPrice.remove();
return price;
Thank you for your help,

It was possible to do it in ASP .NET even from the server side with the method Page.ClientScript. What do you think what Page.ClientScript stands for?
I's an encapsulation for the JavaScript code required and hides the separation between frontend and backend. There was a reason why so many developers stick to the MVC-pattern wich ist violated here.
I did not know it is not possible to do the same thing in Java.I'ts not a task of the backend to layout the user interaction GUI.

Call stateless session bean EJB 2.0 from Webdynpro Java UI

Hello,
Can someone please tell me asto how to call a stateless session bean EJB 2.0 from Webdynpro Java UI?
The NWDS version is 7.0.
Thanks and Regards,
Arya

Hi Aryadipta
Please check this pdfs
https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b00917dc-ead4-2910-3ebb-b0a63e49ef10&overridelayout=true
Steps for calling stateless session bean in Webdynpro java
Go to NWDS -> open perspective ->j2ee
select EJB Module Project ->create a project with name
Open the Project -->RC on ejb-jar.xml -> Select new --> EJB
Give name to EJB Bean (First letter should be in capital letters)
select the type of bean as Stateless session bean and give the package name to store that EJB bean.
After that Expand ejb-jar.xml and then select the <projectEJB>
Double click on this on method tab double click you will get business method where we will create the methods for business logic
Double click on projectEJB and then RC on bean tab and write required business logic in bean window as follows(based on requirement we will design a business logic).
After writing the business logic go to project -> rebuild
Till now we have created one EJB jar file
then go to File-->Enterprise Application Project -->create a project (projectEAR)
After creating a project click on next-> here we will have ear projects and then we select specific project required for our application.(here select projectEJB)
After that Calculate EAR project will be available on j2ee explorer.
Right click on <Bean> here
select New->Web Service->give a name to webservice and select Default configuration type as simple SOAP
-->click next -> Finish.
That webservice and related are created in ejb-jar.xml .
Expand the ejb-jar.xml.and double click on < webservice>
RC ProjectEJB -> Build EJB Archive RC on CalculateEAR ->Build applicationarchive.
Expand the projectEAR->RC on CalculateEAR.ear->Deploy to J2EE Engine
Double click on calculateEAR.ear ->Webservice navigator tab ->we eill servers expand the node
select the specific WebService
Here we test the webservice by click on Test and test it.
After that go to Web dynpro perspective ->create one webdynpro Project and one component
RC on model> Select import Web Service model(last)>give model name and package
and select radio button as local file system or URL
Go to WSnavigator->copy the WSDL path and paste it in model WSDL path and click on finish.
from here onwards steps are same as that adaptive RFC model
Hope it helps

Calling a Report/Transaction iview from Webdynpro..

Hi all,
          Our first issue is we have a scenareio, where we need to execute reports(ABAP Program) from webdynpro. Is it possibile to execute a standard report from webdynpro? using JCO. Also tell me how to pass the input/output parameters.I am not allowed to create RFC.I can use only standard BAPI.
          Our second issue is we created one transaction type callable object, and we want to call this transaction callable object from webdynpro, in another callable object in GP. Is this Possibile in webdynpro. We tried using portal navigation, but it is working for normal webdynpro iviews only, not for url iviews also.
          Does any body know the answer for the above issues. please let us know.
         Thanks in advance.

hi,
1) it is not possible in web dynpro to call abap reports, what you can do is creating wrapper of Remote enabled FM around the report. But you dont have authorisation to create BAPI, so gotta take use of standard BAPIs.
