Calling a Method of Interface by using Object

Hi All,
I want to use a method of a class which will be IF_ABC_XYZ~ <amethod> ( ). how can i use this method in my program , I have the instance of the class which have the above mentioned method?
Thanks & Regards
Pavan

thanks
here the case is like this
data :
       lv_type TYPE REF TO IF_some xyz.
now by using a static class method i am able to get the return type equal to lv_type i.e
CALL METHOD cl_someclassname=> amethod ( )
   IMPORTING
       type      = lv_type.
now when i debug and see lv_type is having a class name inside it. I want to use a method of this class.
How can I call the method which Iam able to see in the lv_type when i debug.

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.

Hi.,
Check this help Document : [Dynamic Method Call in ABAP Objects|http://help.sap.com/abapdocu_70/en/ABENNEWS-46-OBJECTS-DYNAMIC.htm]

Browser Dependency when calling a method in backing bean using a javasript.

Hi all,
I have a problem which may look simple but bugging me for quite some time.
The problem is : When I call a method in the backing bean using a Javascript, (the method can alternatively be invoked by clicking on a command link) I am facing an exception (stack printed below).
The strange part is that...I am getting this exception only when I use Internet Explorer. It works absolutely fine when I use Mozilla or Netscape browsers. Also, even in ie, it is working fine when I click on the link directly. The probem comes only when I invoke the action using a javascript.

Call addEventListener method on stage and my object

What's the difference between calling a method on a stage object and my own object ?
For example:
myCarRectangleShape.addEventListener(Event.ENTER_FRAME, doit);
stage.addEventListener(Event.ENTER_FRAME, doitagain);
Let's suppose I compile the class X that extends Sprite
and myCarRectangleShape is also a sprite object

the only difference it the event target and currentTarget.

How do i call the method in a class using servlet

i am doing a project which need to use servlet to call a few methods in a class and display those method on the broswer. i tried to write the servlet myself but there are still some errors .. can anyone help:

Calling main method in another class using command line arguements

Hi
My program need to use 4 strings command line arguments
entered in Project properties/Run/Application Parameters
java programming for beginners // arguments
The program needs to call main in the second class 4 times using argument 1 the first call, argument 2 the second call on so on.
So the output wil be
java
programming
for
beginners
import java.lang.*;
public class First extends Second{
public static void main(String[] args) {
for(int i = 0; i < args.length; i++){
Second.main(args); // Error I think
import java.lang.*;
public class Second {
public static void main(String[] args){
System.out.println(args[0]);
"First.java": Error #: 300 : method main(java.lang.String) not found in class Second at line 6, column 15
I am only a beginner with little knowledge of java so can the code be as basic as possible

Your style looks quite bad for starters..... Hows
this://import java.lang.*; /* NOT NEEDED */
public class First extends Second{
public First(String s) {
super(s);
public static void main(String[] args) {
for(int i = 0; i < args.length; i++){
new First(s);
public class Second {
public Second(String s)
System.out.println(s);
NOT NEEDED:
public static void main(String[] args){
System.out.println(args[0]);
}My question to you: Do you understand why my code
works? (does it do what you want?)I think since this is some kind of lesson, the OP have to implement some way to use the main method of the Second class as it is, that is, with String[] args. I think this lesson is interesting exactly because of this requirenment. But, anyway, I don�t know, that is just my assumption...

Which object called the method

Suppose there is a class A which has three objects a1,a2,a3 and a method m. Now I'd like to know which particular object has called the method m.

>
which particular object has called the method
What class called my method
http://developer.java.sun.com/developer/qow/archive/104
a.The advice in the posted link is unreliable as the format of printStackTrace() is not standardized. A more reliable way to find out the calling class is to use SecurityManager.getClassContext() or Throwable.getStackTrace() [in JDK 1.4+].
However, it is not clear whether the original poster wanted to know the calling class or the calling object. In the latter case there is no easy way except for modify the signature of method m to accept the reference to the calling object.

Calling a method from object o

hi
event.getsource() returned a variable of type object. But in fact, this object is of type JTextField.
Now, I want to call : the method getName of this returned object.
This doesn't work:
JTextField tf = (JTextField)e.getSource();
tf.getName();
it allways returns null.
what am i doing wrong?
Thank you!
Christian

if tf.getName() returns null (rather than throwing a NullPointerException which is different) then the reason is that the name of the returned field IS null.
Are you sure you didn't mean to call tf.getText() ?

Using AJAX to call a method of controller.

I am working with weblogic 10.2 .I need to call a method of the controller using Ajax (because i don't wan to refresh the whole page).
I am new to Ajax.
Can any one provide me the stub or prototype for calling a method of contoller from jsp using AJax.

Another approach, if you would like to call a Pageflow action and then update only a portion of a portlet with the result, would be to use the Dynamic Content taglib.

Calling a method within an application?

Hi I'm a student taking an intro Java class and right now I have to develop and application that prompts for someone to input a character of the alphabet and it will display the corresponding number on a telephone that it is listed under. The main method gets the input from the user and we are required to retrieve the corresponding digit to the character from a separate method using either a switch statement or a nested if-then-else statement to determine what the digit is. I'm having trouble calling that method in the main class which is another requirement. any suggestions?

        win.print("Enter a letter: ");
        letter = in.nextLine().charAt(0);
        letter = Character.toUpperCase(letter);
     * Get the digit on a telephone keypad that corresponds
     * to the specified character. If the character is neither
     * a letter nor a digit, this method will retun the
     * asterisk character: '*'
     * @param letter the specified character
     * @return the corresponding digit
    private static char getPhoneDigit(char letter)
        char digit;
        digit = '*';
        if(letter == 'A' || letter == 'B' || letter == 'C')
            digit = '1';
        return digit;
}

Your method is static so you can call your method without creating a Hmwk08 object.
char result = getPhoneDigit(letter);Would suffice in your main method

Getting an error when calling the method of the bean

Hi,
I have the following problem:
From my action class I'm calling a method on EJB through Business Object and getting the following error:
org.apache.struts.action.RequestProcessor Unhandled Exception thrown: class gov.nyc.fisa.wbas.exceptions.ServerException
[3/6/08 13:53:44:700 EST] 1acdd938 WebGroup E SRVE0026E: [Servlet Error]-[SERVER EXCEPTION CALLING searchBenefitGroups() METHOD ]: gov.nyc.fisa.wbas.exceptions.ServerException: SERVER EXCEPTION CALLING searchBenefitGroups() METHOD
The following are parts of my code:
In Action Class:
BenefitGroupBO bo = new BenefitGroupBO();
BenefitGroupsColView cView = new BenefitGroupsColView();
try{
    cView = bo.searchBenefitGroups(transferObject,true);
catch (ServerException e){
    throw new ServerException("SERVER EXCEPTION CALLING searchFunds() METHOD ",e);
In Business Object:
private BenefitGroupImpl benGrpImpl = null;
    try{
           System.out.println("1. BenefitGroupBO - searchBenefitGroups()");
           collectionView = benGrpImpl.searchBenefitGroups(transferObject, isSearch);
           System.out.println("2. BenefitGroupBO - searchBenefitGroups()");
catch (RemoteException e){
            throw new ServerException("Remote exception calling BenefitGroupImplBean: searchBenefitGroups()", e);
.....It never executes the second print statement in the method
In Remote Interface:
public BenefitGroupsColView searchBenefitGroups(BenefitGroupVO transferObject, boolean isSearch)
                                                                       throws ServerException, java.rmi.RemoteException;
In the EJB
public BenefitGroupsColView searchBenefitGroups(BenefitGroupVO transferObject, boolean isSearch){
                                                                    throws ServerException
         System.out.println("1. BenefitGroupImplBean - searchBenefitsGroups() method");
         BenefitGroupsColView collectionView = new BenefitGroupsColView();
         System.out.println("2. BenefitGroupImplBean - searchBenefitsGroups() method");
          return collectionView;
.....It never executes first Print statement in that method and I do not think it ever goes into the actual EJB class.
Can anyone tell me what am I doing wrong?
Thank you

Regarding BDC and Call transaction Method

hi gurus,
can anyone tell the difference how many records Call transaction and Session
Method can upload in case of single transaction and what is the time taken by each.its urgent pls.
thanks and regards.

Rajesh,
u can do as many as ,
coming to speed means it depends on server,
if ur using session then u can calculate time ,
with in one time h many records system will upload the records by seeing in sm35
(first see h many records systems uploads, see the number and put the time , after one min again see the records h many it is ,) u can calculate by this.
remember this speed will changes depends on server,
so if u have n number of records better to do upload in weekends.
2) if u r using call transaction method means , normally we use error file where ever record occurs that record is in error file, i think we cant analyze h many records it will be with in a time r .
we can also check by going respective tables , just put the time and do refreshing the table after one minute , n this way u can analyze .
Thanks
