Calling of an observer method in ActionComponent

Hi
I like to call a method of an observer of a panel in my ActionComponent class.
- How can I do that?
- Have I to write an Interface to the observer class, get this interface via the boss of the panel and call then the method? If yes how can I get the boss of the panel in the ActionComponent class?
Thanks for any help.

You have to hop a few objects. Follow this trail:
ISession::QueryApplication
IApplication::QueryPaletteManager
IPanelMgr::IsPanelWithWidgetIDShown(yourPaletteID)
IPanelMgr::GetVisiblePanel(yourPaletteID)
IPanelControlData::FindWidget(yourWidgetID)

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.

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.

Calling a backing bean method after load of fragment in adf

I needed to call a backing bean method after page load of fragment in adf.
I used the method suggested in:
https://community.oracle.com/message/11044570
only difference is im giving the if clause as:
if (refreshFlag == RegionBinding.RENDER_MODEL ) {
instead of
if (refreshFlag == RegionBinding.PREPARE_MODEL)
It was working fine, but page was not getting refreshed so used the code as mentioned in example:
public void refresh() {
          FacesContext facesContext = FacesContext.getCurrentInstance();
          String refreshpage = facesContext.getViewRoot().getViewId();
          ViewHandler viewHandler =facesContext.getApplication().getViewHandler();
          UIViewRoot viewroot = viewHandler.createView( facesContext, refreshpage);
          viewroot.setViewId(refreshpage);
          facesContext.setViewRoot(viewroot);
Now issue is once page is loaded and backing bean method is called, the refresh code refreshes the page and upon page load, refresh method is called again in recursive fashion.
please advise what to do in such scenario?
I tried to do selective refresh using some variable(also with static) but it does not help as page wont be refresh at all or page will keep refreshing recursively.

Error in CALL TRANSACTION and SESSION Method

How to call a standard BOR method in a program.

Hi All,
How to call a standard BOR method in a program. For example I have to call BOR method ISUSMORDER.Release in my program but don't know how to call.
Also, plz tell me how to capture the Exceptions in case of BOR method.
Plz help me out in this.
Thanks,
Mithilesh

Would be easier (however not always possible), to determine the functionality of this method and call that in your program. I mean, normally this method calls a BAPI, or function module (or a transaction). Have a look at the coding inside of the method, and try and use this.

When do we go for a Call Transaction or Session Method in BDC

Hi All,
Please let me know the scenario when we will go in for
1. Call Transaction
2.Session Method.
What is the main difference between Call Transaction and Session Method
Regards

hi,
Use the CALL TRANSACTION USING statement
Summary: With CALL TRANSACTION USING, the system processes the data more quickly than with batch input sessions. Unlike batch input sessions, CALL TRANSACTION USING does not automatically support interactive correction or logging functions.
Your program prepares the data and then calls the corresponding transaction that is then processed immediately.
The most important features of CALL TRANSACTION USING are:
Synchronous processing
Transfer of data from an individual transaction each time the statement CALL TRANSACTION USING is called
You can update the database both synchronously and asynchronously
The program specifies the update type
Separate LUW (logical units of work) for the transaction
The system executes a database commit immediately before and after the CALL TRANSACTION USING statement
No batch input processing log
Create a session on the batch input queue.
Summary: Offers management of sessions, support for playing back and correcting sessions that contain errors, and detailed logging.
Your program prepares the data and stores it in a batch input session. A session is a collection of transaction data for one or more transactions. Batch input sessions are maintained by the system in the batch input queue. You can process batch input sessions in the background processing system.
Your program must open a session in the queue before transferring data to it, and must close it again afterwards. All of these operations are performed by making function module calls from the ABAP program.
The most important aspects of the session interface are:
Asynchronous processing
Transfers data for multiple transactions
Synchronous database update
During processing, no transaction is started until the previous transaction has been written to the database.
A batch input processing log is generated for each session
Sessions cannot be generated in parallel
The batch input program must not open a session until it has closed the preceding session.

Dynamic call of a static method of an static attribute

Hi all,
is it possible to call dynamically a static method of a static attribute of a class.
The statement without dynamic call would look like this:
cl_test_class=>static_attribute=>static_method( ).
I would like to do it like this:
('CL_TEST_CLASS')=>static_attribute=>static_method( ).
Netiher the one nor the other way works for me - I'm getting the error "The notation used is reserved for business object classes".
Regards, Stefan

I guess, it is not possible to call method using the short form (parameters in brackets) is not possible in Dynamic Access. You may need to get the attribute first and then call the method.

Carol,
The file is not being read by the programmer.
The problem seems to be coming when the code tries to return from an ejb call A hashtable is returned while coming back. In this hashtable, the data is present in the form of XML DOM Object(oracle implmentation, because oracle xml development kit is used). I think this exception is coming when EJB tries to serialise the object to send it back.
So, this exception is compeletely stemming from internal classes of Oracle
The code is part of a web project.

How to call the screen in methods could u please explain

hi,
how to call the screen in methods could u please explain clearly with example

HI ,
CALL SCREEN - Call a screen
Basic form
CALL SCREEN scr.
Addition:
... STARTING AT x1 y1 ... ENDING AT x2 y2
Effect
Calls the screen scr; scr is the number of a screen of the main program. You use SET SCREEN 0. or LEAVE SCREEN. to define the return from the CALL screen.
Note
Please consult Data Area and Modularization Unit Organization documentation as well.
Addition
... STARTING AT x1 y1 ENDING AT x2 y2
Effect
The coordinates x1, y1 (start column and start line in the window) and x2, y2 (end column and end line in the window) define the size and position of the CALL screen ("top left - bottom right"). Besides these coordinates, you can also see the contents of the primary window, but cannot perform any action there.
Note
If "ENDING AT ..." is not specified, suitable values are substituted for x2 and y2, taking into account the size of the called screen.
Exceptions
Non-Catchable Exceptions
Cause: No further screen level (call screen); the maximum number of nested screen levels is restricted to 50 at present.
Runtime Error: DYNP_TOO_MANY_CALL_SCREENS
THX

Calling a external Java method from JSP - using Tomcat server

Hi all,
I am trying to call a method in an external Java file from my JSP. I am using Tomcat server.
I have my class within the package package "mypackage" and it is called myclass.class. It has only one static method mymethod() which reads from a file and writes to a file.
I compiled the java class and I put the class file under webapps/ROOT/web-inf/classes/mypackage/myclass.class
I am trying to say something like this from my JSP file(which is under webapps/ROOT) :
<%@ page import = "mypackage.myclass"%>
<% myclass.mymethod(); %>
I am not instatiating the class as its a static method.
This is what I get while accessing my jsp file :
javax.servlet.ServletException: try to access class mypackage.myclass from class org.apache.jsp.index_005ftest_jsp
To put my problem in a nutshell, Can someone guide me how to access a method of an external class from a JSP page? I have a bunch of pages doing the same operation so I thought I would have it in a method and call it from every page. Even though I tried to put the file under web-inf/classes, The JSP is not able to see the class.
Please help.
Thanks
-Uday

I have a situation that is a bit similar. I have successfully used beans for storing methods used in JSPs and used by other methods in the same class as was suggested above. Now I would like to break some methods into another (utility) class since they are lower level and can be used by lots of things. They are for database operations (given a String query and String dbname, it queries and returns ResultSet for example). I want to have them in a separate class for reusability and OOP.
I am having problems calling those public static methods in the public class from my bean that communicates with the JSP. I can't compile the class that calls the method in the database ops class. I get an error like :
loginHelper.java:45: cannot find symbol
symbol : variable sqlHelper
location: class dbHelperBean.loginHelper
and when I include the package name in the call I get
loginHelper.java:45: cannot find symbol
symbol : class sqlHelper
location: package dbHelperBean
That's strange since the package of both classes is dbHelperBean and the class is indeed called sqlHelper. I tried to compile it in the same directory as sqlHelper as well. What am I doing wrong?
Thanks for any help.

<p>I just wanted to provide an update to this. I did find a work-around for this, but I cannot explain it. The post I added to a related thread on 23 Sept. 2009, Trying to change the data source for a Crystal Report. (thread 1472257), explains a work-around I found for that problem. It seemed to resolve this one simultaneously.

<p>
I don't know why it works. If anyone has a comment or some insight, it is welcome. Thank you in advance.
