Calling class method

Hi,
In classical report we click on the pattern and write the funciton module name there to get the import and export parameter of the fucntion.
Can somebody tell me how to call the class method in the program with the parameters coming automatically .
Thanks

hi Arvind,
Click on pattern.
Choose ABAP object pattern radio button and press enter.
You have four radio button-the first one call method is for your requirement.
Enter the object instance name, class name and method name and press enter.
You will get the call method for this instance of the class.
Hope this helps.
Regards,
Richa

Calling class methods from jsp

hi - this seems like it should be painfully obvious but I am missing something somewhere and can't seem to get it to work.
The end result I am looking for is to be able to call a method similar to how I would do it in PHP or ASP.
To do this I have writte the following class (just as an example) and combpiled it to /WEB-INF/classes/com/example/util/Echo.class:
package com.example.util;
class Echo
public static void main(String[] args)
System.out.println(args[0]);
I then have a sample JSP that I attempt to use this in that looks like:
<%@ page import="com.example.util.Echo" %>
<%
RDmail("I'm using my Echo class.");
%>
My expectation would be that when I run this page in a browser, I see the text "I'm using my Echo class." printed out on the page. Instead I get the following error:
An error occurred at line: 1 in the jsp file: /classtest.jsp
Generated servlet error:
[javac] Compiling 1 source file
/var/tomcat4/work/Standalone/localhost/raindance/classtest_jsp.java:47: cannot resolve symbol
symbol : method Echo (java.lang.String)
location: class org.apache.jsp.classtest_jsp
Echo("I'm using my Echo class");
^
1 error
What am I doing wrong?

Umm... I'm not entirely sure what you're attempting to do, but it looks like there's some discrepancy between your error message and your code...
RDmail("I'm using my Echo class."); in your code
and
Echo("I'm using my Echo class"); in your error message.
Is this just a cut/paste error?
Also, the main() method is only called from a command line, and will not be run when you instantiate your bean in a JSP. If you want to have your String printed out when you create a new object, you should put the print statement in the constructor. Which would then be called when you created a new object..
Echo e = new Echo("I'm using my Echo class");
Or, you could create a static method inside Echo.java that prints out the statement.
Finally, your System.out most likely will not print to your browser, but probably to a standard log, or perhaps a command window.

Newbie Q'n -- Calling class methods without instantiation

Hello All,
I would like to know how is it possible to call methods within a class without instatiating the class.
For instance consider the following statement:
String x = Integer.toString(10);
Here there we are calling the toString() function of "Integer" class without instantiating it. How is it possible?? How does the JVM call the toString() function when there is no Integer object defined in my program?? Can the same functionality achieved for user created classes ??
Can anyone explain ??
If this appears as a trivial question, please forgive me.
Thanks in advance,
Arun

String x = Integer.toString(10);
Here there we are calling the toString() function of
"Integer" class without instantiating it. How is it
possible?? How does the JVM call the toString()
function when there is no Integer object defined in my
program?? Can the same functionality achieved for user
created classes ?? It isn't possible, and its not happening in your example either:
toString() is an instance method. toString(int) and toString(int, int) are class (static) methods.
You might see documentation referring to a toString (notice no "()" at the end) method. When you do, it should usually be clear from the context which particular method is being referred to.
Such confusion might well have been avoided if the original API designers had thought to call the methods something different (perhaps format?), but they didn't (in fact, toString(int) seems rather pointless).

Error calling class methods CL_GUI_FRONTEND_SERVICES

Hi all,
I have a requirement in BAPI (integrating solman to portal) to download file from app. server to local directory. I used the below FM to get temp directory of presntation server.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_TEMP_DIRECTORY
   CHANGING
     TEMP_DIR             = LV_TEMP_DIR
   EXCEPTIONS
     CNTL_ERROR           = 1
     ERROR_NO_GUI         = 2
     NOT_SUPPORTED_BY_GUI = 3
     others               = 4.
   CALL METHOD cl_gui_cfw=>flush.
It works fine in R3, but when i called it from portal it shows Access not possible using 'NULL' object reference with a short dump .
st22 shows
Error in ABAP application program.
The current ABAP program "CL_GUI_FRONTEND_SERVICES======CP" had to be
terminated because one of the
statements could not be executed.
This is probably due to an error in the ABAP program.
An exception occurred. This exception is dealt with in more detail belo
. The exception, which is assigned to the class 'CX_SY_REF_IS_INITIAL',
neither
caught nor passed along using a RAISING clause, in the procedure
"GET_TEMP_DIRECTORY" "(METHOD)"
Since the caller of the procedure could not have expected this exceptio
to occur, the running program was terminated.
The reason for the exception is:
Attempt to access a component using 'NULL' object reference (points
to nothing).
An object reference must point to an object (an instance of a class)
before you can use it to access components (variable:
"CL_GUI_FRONTEND_SERVICES=>HANDLE").
Either the reference has not yet been set, or it has been reset to
'NULL' by a CLEAR statement.
When i put external break point and the dump comes during execution of CALL METHOD cl_gui_cfw=>flush.
Is it not possible to use CL_GUI_FRONTEND_SERVICES in RFC ??.
thanks and regards
Jijo

[CL_GUI_FRONTEND_SERVICES|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=cl_gui_frontend_services+portal&adv=false&sortby=cm_rnd_rankvalue] needs a SAPGUI, so it is not possible to use it in RFC, BSP or other portal.

Does calling class methods from bean and JSP cause collision?

Hi,
Please look at the class below:
public class X
// no member variable
public X() {}
// pay attention to static keyword
public static int getY()
Think a bean (say BeanZ) that make calls to getY() method without initializing the class X (like this: X.getY() )
And think many users having "page scope" in JSP make call to BeanZ or directly calls it from JSP.
I'm wondering if any collision occurs because of STATIC method? Should I use "SYNCHRONIZED" keyword with it? If so, what about Math.cos() which also is a non synchronized static method ? Shouldn't I use Math.cos() (and the other static methods) in JSP or bean?
Thank you for your help.
Ali Sadik

Hi,
Thank you for your quick answer. Think my class like this:
public class X
// no member variable
public X() {}
// pay attention to static keyword
public static int[] getY(int a, int[] b)
// i know there is no need for the extra array.
// just for example ;)
int[] ret = new int[b.length];
for(int i = 0; i < b.length; i++)
ret[i] = a * b;
return ret;
Does it the type of class that you've mentioned ? It makes calculation to produce dynamic result. Shouldn't I use it as static ? If your answer is yes, what about Math.cos()? Doesn't it have dynamic calculation?
Thanks a lot.

Calling class methods from listSelectionListener

Hi,
I have a GUI class which containt a few Jlist. I also have two listSelectionListener classes. How do I reach methods in the GUI class from the listSelection classes. Can I pass a reference of GUI to them somehow?
Karl XII

For the benefit of future readers, the answer is yes, either in your listSelectionListener constructor, or a listSelectionListener method you implement. In either case, just set a listSelectionListener member variable (added by you) to the desired value.

In webdynpro ,Passing field symbols as values to class methods

Hi
Please tell me the ways of accessing database in webdynpro abap(not directly). I am calling Class method for accessing database. As currently I am directly accessing database in my webdynpro application. I have created a class and method for the same.
In my method I want to use select statement which will return table with values to webdynpro application. So for select statement(Calling Method) I need to use my field symbol values as where in clause .
Could anyone please help with example code?
Thanks,
Ujjwal

data: in_line type ref to data.
CREATE DATA in_line LIKE LINE OF <dyn_tab>.
ASSIGN in_line->* TO <dyn_wa>.
You can create a data reference and assign it to a field symbol and change the values. direclty passing field symbols is not possible.

Automatically detect the caller class!

Guys,
I have a simple but "sounds-like-general-and-interesting" doubt..
I have a class 'A' and another class 'B'. I have a method in 'A' called 'a' calling a method in class 'B' (which is 'b').
suppose the control is inside the method 'b' of the class 'B'.
Now, the doubt is
how can I find out that it was class 'A' who called the method 'b' of class 'B' from within the method 'b'?
the scenario is a simpe loging scenario where the class 'B' is a Logger class and I want to automatically detect the class calling this component from within this component so that it can be logged too.
Hope my problem is clear. Thankx in advance for the replies.. am stuck and confused too.. and hop there's a solution for this
regards
Manesh

mgumbs is right - typically a Logger class will accept a context (Object) to indicate where the message has come from. Sometimes people pass in "this", sometimes they pass in "this.class" or sometimes they'll log on behalf of another class. It's pretty much the same solution - if it's needed you should supply it.
One method made possible in J2SDK-1.4 is using a stack trace to find out what the calling class/method is. Perhaps the only way to do that would be to throw a new Exception and get hold of its stack trace elements. I suspect that this would add significant overhead, though, and I certainly wouldn't recommend it!

How to find out which class/method is calling System.gc

Hi
I am seeing frequent FULL GC and not able to locate which particular class/method is calling the System.gc(). I have disabled it using -XX:DisableExplicitGC and performance issues have been resolved. Also, I noticed that it does not happen periodically, so it is not RMI GC. How to find out who exactly is doing this? Does any of of the profilers like Optimizeit/Jprobe help find out this.
Thanks

Hi
I am seeing frequent FULL GC This is because you are creating and destroying objects VERY frequently. Try to look at your design and see where you can reuse objects (i.e. object pooling) if possible, that is if this is adversely affecting performance.
and not able to locate
which particular class/method is calling the
System.gc(). Classes don't call GC. The VM handles that automagically.

How to load a class dynamically and then a call a method?

Hi
I want to call a method from a class,which class is loaded dynamically.
Consider a classA and ClassB..
ClassB contains a method showvalue() which returns a String value.
I want to load a ClassB dynamically in ClassA,and call the method showvalue() and print the returned value of that method (showvalue).
How to do this?
Thanks

Since you found your way to Reflections and Reference Objects, I can only assume you know that reflection is the answer. Since the reflection tutorial on this site, and indeed, the many others on the web, can explain this a whole lot better and more consisely than can be done in a forum, I'll point you in that direction instead. As a starting point, and to show I'm not just fobbing you off, you're interested in the classes java.lang.Class, java.lang.reflect.Method, and the method Class.getMethod(String, Class[])

How to call a class method from a jsp page?

Hi all,
i would like to create a basic jsp page in jdev 1013 that contains a button and a text field. When clicking the button, i would like to call a method that returns a string into the text field.
The class could be something like this:
public class Class1 {
public String getResult() {
return "Hello World";
How do i go about this?

How to Call a Class method in another class.

Hi All,
I have created two class
The class JavaAgent create a object of another TestFrame1 class . I am trying to call
out.setSize(200,100);
out.setVisible( true );
above two method.
I am a doing some thing wrong. I am getting the error " symbol cannot be resolved".
public class JavaAgent extends AgentBase {
private TestFrame1 out;
private Session session;
private Database db;
private Frame frame;
     public void NotesMain() {
          try {
               Session session = getSession();
               AgentContext agentContext = session.getAgentContext();
Database db = agentContext.getCurrentDatabase();
String title = db.getTitle();
// System.out.println ("Current database is \"" + title + "\"");
               TestFrame1 out = new TestFrame1( );
out.setSize(200,100);
out.setVisible( true );
Thread.sleep(250);
          } catch(Exception e) {

import lotus.domino.*;
import java.awt.*;
import javax.swing.*;
class TestFrame1
private Session session;
private Database db;
TestFrame1( )// Constructor
JFrame frame = new JFrame("Test Frame 1");
}

Hi,
I guess you are not able to invoke setSize and setVisible method. Am i right ??
First make sure your TestFrame class is compiled.
The setSize() and SetVisible are defined in Component and inherited by JFrame.
In order to use these methods you have to make your TestFrame as subclass of JFrame or provide a utility method
and from there explicitly call these methods by using the associated JFrame reference.
And in your JavaAgent class why you declared TestFrame1 twice?? it's really hard to predict your intention.
Anyway i hope this code will helps you bit...
import javax.swing.JFrame;
public class JavaAgent{
     JavaAgent()
      * @param args
     public static void main(String[] args) {
          TestFrame1 test = new TestFrame1("Test Frame1");
          test.setSize(250,250);
          test.setVisible(true);
class TestFrame1 extends JFrame
     TestFrame1(String title)
          super(title);

Calling a method from a super class

Hello, I'm trying to write a program that will call a method from a super class. This program is the test program, so should i include extends in the class declaration? Also, what code is needed for the call? Just to make things clear the program includes three different types of object classes and one abstract superclass and the test program which is what im having problems with. I try to use the test program to calculate somthing for each of them using the abstract method in the superclass, but its overridden for each of the three object classes. Now to call this function what syntax should I include? the function returns a double. Thanks.

Well, this sort of depends on how the methods are overridden.
public class SuperFoo {
public void foo() {
     //do something;
public void bar(){
     //do something
public class SubFoo extends SuperFoo {
   public void foo() {
      //do something different that overrides foo()
   public void baz() {
      bar(); //calls superclass method
      foo(); //calls method in this (sub) class
      super.foo(); //calls method in superclass
}However, if you have a superclass with an abstract method, then all the subclasses implement that same method with a relevant implementation. Since the parent method is abstract, you can't make a call to it (it contains no implementation, right?).
