How to call a method in IMPL class from one context node

Hi, I´ve been only study the posibility to access a method in the IMPL class from one context node class...CN## without using events, is there a way to call it ??? I don´t have it as requierement just learning thanks !.

Hi,
Try this by following this you can get the custom controller instacne in the view context nodes, for your requirement you can keep the view implementation class instance instead of cuco..
To get the custom controller instance in Context node getter/setter method:
1. Declare Cuco instance reference variable in ctxt class..
2. Set this cuco ref. in the Create context node method of ctxt class:
try.
gr_cucoadminh ?= owner->get_custom_controller( 'ICCMP_BTSHEAD/cucoadminh' ). "#EC NOTEXT
catch cx_root.
endtry.
you can avoid this step as this is not needed in case of view isntance
3. Assign this instance to the respective context node Create method using:
BTStatusH->gr_cuco ?= gr_cucoadminh. " here assign the view implementation ref. " me" instead of gr_cucoadminh
Here gr_cuco is the ref. variable of custom controller in the respective context node for eg. BtstatusH
Sample implementation of this can be found in
ICCMP_BTSHEAD/BTSHeader ->context node BTACTIVITYH-> attr ->GR_CUCO(instance of cuco)

How to call particular method in action class from Portlets StrutsContent

I am developing a web application which uses weblogic portlets and struts. This is what I have for now in the .portlet file.
+<netuix:strutsContent action="getStudentList" module = "people/students"+
refreshAction = "getStudentList" reqestAttrpersistence="none"/>
I want it to change something like this:
+<netuix:strutsContent action="getStudentList.do?method=allGrads" module = "people/students"+
refreshAction = "getStudentLis.do?method=allGrads" reqestAttrpersistence="none"/>
But this is not working. So how can I achieve something like that?
Thanks

No, i dont know how to call other than main methods from other classes
And one more doubt i have i.e. Like in C can we see the execution of the program like how the code is being compiled step by step and how the value of the variable changes from step to step like(Add Watch).........

How to call a method of a class from another class

Hi,
Can some one explain me this? I want the label from the Label class to be displayed in the JFrame. I understand to do this, I have to call "label" to the ABC() and createAndShowGUI().
I am novice. It will be really helpful if you could explain me what you did.
class Label {
public Label() {
public JTextField label;
label = new JTextField("Hi");
public ABC() {    //Constructor
          Container c = getContentPane();
          c.setLayout(new FlowLayout());
    private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame frame = new JFrame("FrameDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JLabel emptyLabel = new JLabel("");
        emptyLabel.setPreferredSize(new Dimension(600, 400));
        frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
        //Display the window.
        frame.pack();
        frame.setVisible(true);
    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
    }Will it be some thing like this?
public ABC() {    //Constructor
          Container c = getContentPane();
          c.setLayout(new FlowLayout());
                Label label = new Label();

You know it maybe that it's just too late at night for me, but I see you complete Label class, but I don't see a class definition for ABC; you have a constructor for it, but not a class definition for it.
In any case, when you define a class, you use it in the same way any other class is used...
MyClass myObjectRef = new MyClass();

How to call a method of another class ?

Hello,
I�d like to know how to call a method of another class. I have to classes (class 1 and class 2), class 1 instantiates an object of class 2 and executes the rest of the method. Later, class 1 has to call a method of class 2, sending a message to do something in the object... Does anybody know how to do that ? Do I have to use interface ? Could you please help me ?
Thanks.

Calling another method in the class from within the body of a method Im wri

Hello out there.
I have a question. I keep getting an error that reads as follows:
1 error found:
File: /Users/matthieubell/Academia/University of Waterloo/CS 125/L06/CreditCard.java [line: 80]
Error: double cannot be dereferenced
I think it is occuring because I am trying to call a method on an instance variable, which is not an object. But how do call a method I have already written, on another method I am writing in the general sense. I could make a particular object, but Im not shure that would get me the same result. I want to be able to call the method calcMinPayment on the instance variable currentBalance to wirte the method makePayment.
I have a class CreditCard
with the instance variables "private double currentBalance = 0; "
public double calcMinPayment()
// Add code here
double minimumPayment;
if (currentBalance < 50)
minimumPayment = currentBalance/10;
else
minimumPayment = 50;
return minimumPayment; // Replace this statement
* This method will decrease the current balance on the credit card if
* this payment meets or exceeds the minimum payment amount.
* pre: paymentAmt > 0
* post: The current balance should be decreased by paymentAmt if
* paymentAmt >= the minimum payment amount. Otherwise, the payment
* will not be recorded and an appropriate error message should be
* displayed.
public void makePayment(double paymentAmt)
// Add code here
double minimumPaymentAmount;
minimumPaymentAmount = currentBalance.calcMinPayment();
if (paymentAmt < minimumPaymentAmount)
System.out.println("Sorry, but your payment must exceed the minimum payment amount.");
System.out.println("This payment has not been recorded, please try again.");
else
this.currentBalance = currentBalance - paymentAmt;
thanks for youre help
-Matthieu

'calcMinPayment' takes no arguments, uses a member variable (currentBalance) to compute a local variable 'minimumPayment' which it returns, ie, sends back to the caller. So you can call 'calcMinPayment' at any time.
minimumPaymentAmount = calcMinPayment();

How to call a method in the servlet from an applet

I want to get the data for the applet from the servlet.
How to call a method that exits in the servlet from the applet? I want to use http protocol to do this.
Any suggestions? Please help.
thanks

Now that Web Services is around, I'd look at possibly implement a Web Service call in your applet, which can then be given back any object(s) on return. Set up your server side to handle Web Service calls. In this way, you can break the applet out into an application should you want to (with very little work) and it will still function the same

How to call a method of a class where the name of method is string

i have a method of a class in the form of a string and i have the object of the class to which it belongs .what i want to do is call this method.
for ex:
S1 s=new S1();
// this is the object of my class. this class has one method called executeMe()
String methodname="executeMe";
//i have the name of the method with me in the form of string.
so how can i call the class's method in this scenario from the string like what should i write in sucha way that i get s.executeMe(); it is not presumed that this will only be the method that will be called. there maybe some other method too and it has also to be called this way. so please guide.

S1 s = new S1();
String name = "executeMe";
Method m = s.getClass().getDeclaredMethod(name,null); // no parameters
m.invoke(s,null);Built from memory, maycontain flaws.

How to call setter Method of ActionScript class with in a Flex Application

Hi
I have Action class as shown :
public class MyClass
private var name:String
public function get name():String {
    return _initialCount;
public function set name(name:String):void {
    name = name;
Now please let me know how can i access this Action class under my Flex Application and call the setter Method of it to set the value for the name .
For example on entering some data in a TextInput and click of a submit Button , on to the Event Listener , i want to call the set name method of my ActionScript class .
Please share your ideas on this .

Thanks Gordon for your resonse .
Say for example my Action class is like this :
public class MyClass
private var name:String
public function get name():String {
    return name;
public function set name(name:String):void {
    name = name;
This is inside the MXML
I know this way we can do it
public var myclass:MyClass = new MyClass();
myclass.name="Kiran";
Now my query is can we do in this way also ??
myclass.set name(SomeTextInput.text);
Please share your views on this , waiting for your replies .
Thanks in advance .

                                         im_dt2 like tp2
                                         im_dt3 like tp3
                                         im_dt4 like tp4
                           returning value(re_dt1) like tp5.
endclass.
i have the final data that has to be displayed in internal table re_dt1.
now my question is how to call this method present in private section into public section and display the data present in re_dt1.
Thanks,

Hi,
what you need is one public method being called at start-of-selection. Within this the private methods have to be called.
The question is, why has the method for reading the database tables to be private? If you have only one private method reading all database tables the public method being called at start-of-selection will only consist of a call-method statement.
This seems to be one call to much.
The logic for reading the different database tables is hidden inside the class anyway.
Is there any further logic reading the different database tables?
Have always all table to be read? If not another approach would be one private method for each database table being called by a public method deciding which table has to be read:
public section.
methods get_data returning value(re_Dt1).
private section.
methods:
get_table_a returning value(im_dt1),
get_table_b returning value(im_dt2),
get_table_c returning value(im_dt3),
get_table_d returning value(im_dt4),
combine_data importing im_dt1
                                im_dt2
                                im_dt3
                                im_dt4
                        returning value(re_dt1).
*- implementation of public method:
method get_data.
data: lt_dt1 ...
           lt_dt2,
           lt_dt3,
           lt_dt4.
* here decide which tables have to be read:
lt_dt1 = get_table_a( ).
lt_dt2 = get_table_b( ).
lt_dt3 = get_table_c( ).
lt_dt4 = get_table_d( ).
re_dt1 = combine_data( i_dt1 = lt_dt1
                                       i_dt2 = lt_dt2
                                       i_dt3 = lt_dt3
                                       i_dt4 = lt_dt4 ).
endmethod.
*- implementation of private methods
method get_table_a.
endmethod.
method get_table_b.
endmethod.
method get_table_c.
endmethod.
method get_table_d.

How to call a method from a separate class using IBAction

I can't work out how to call a method form an external class with IBAction.
//This Works 1
-(void)addCard:(MyiCards *)card{
[card insertNewCardIntoDatabase];
//This works 2
-(IBAction) addNewCard:(id)sender{
//stuff -- I want to call [card insertNewCardIntoDatabase];
I have tried tons of stuff here, but nothing is working. When i build this I get no errors or warnings, but trying to call the method in anyway other that what is there, i get errors.

Can you explain more about what you are trying to do? IBAction is just a 'hint' to Interface Builder. It's just a void method return. And it's unclear what method is where from your code snippet below. is addNewCard: in another class? And if so, does it have a reference to the 'card' object you are sending the 'insertNewCardIntoDatabase' message? Some more details would help.
Cheers,
George
