I try to use this code

What is the syntax for calling function from class file by jsp

does anyone here knows what is the syntax of how to call a function from java class file by javascript code or any way to call it?
and where should i put the calling function code? because the function is called depend on the user click.
for example
<%=pc.functionName(a,b)%>
for the variable a and b, how can i get the value from html textbox and put it in a and b...
urgent needed...
thx

Jsp's are executed before the Html forms are created and loaded. Dont try to use a java code function calling on a javascript click. You'll have to explicitly redirect it into a servlet where in you can call the function you want.
Well! another way could be using AJAX. That seems to be powerfull enough and it might also serve your purpose.
Hope this helps

}in another class A (the main class where i run everything) i created a new instance of dice and added it onto a JPanel.Also a JButton is created called roll, which i added a actionListener.........rollButton.addActionListener(B); (B is instance of class B)
In Class B in implements actionlistener and when the roll button is clicked it should call "roll()" from Dice class
Dice d = new Dice();
d.roll();
it works but it does not repaint the graphics for the dice? the roll method will get a random number but then it will call the method to repaint()???

One way:
class Flintstone
    private String name;
    public Flintstone(String name)
        this.name = name;
    public String toString()
        return name;
    public static void useFlintstoneWithReference(Flintstone fu2)
        System.out.println(fu2);
    public static void useFlintstoneWithOutReference()
        Flintstone barney = new Flintstone("Barney");
        System.out.println(barney);
    public static void main(String[] args)
        Flintstone fred = new Flintstone("Fred");
        useFlintstoneWithReference(fred); // fred's the reference I"m passing to the method
        useFlintstoneWithOutReference();
{code}
can also be done with action listener
{code}    private class MyActionListener implements ActionListener
        private Flintstone flintstone;
        public MyActionListener(Flintstone flintstone)
            this.flintstone = flintstone;
        public void actionPerformed(ActionEvent arg0)
            //do whatever using flinstone
            System.out.println(flintstone);
    }{code}

How to load function from derived class from dll

Dear all,
how to access extra function from derived class.
for Example
//==========================MyIShape.h
class CMyIShape
public:
CMyIShape(){};
virtual ~CMyIShape(){};
virtual void Fn_DrawMe(){};
// =========== this is ShapRectangle.dll
//==========================ShapRectangle .h
#include "MyIShape.h"
class DLL_API ShapRectangle :public CMyIShape
public:
ShapRectangle(){};
virtual ~ShapRectangle(){};
virtual void Fn_DrawMe(){/*something here */};
virtual void Fn_ChangeMe(){/*something here */};
__declspec (dllexport) CMyIShape* CreateShape()
// call the constructor of the actual implementation
CMyIShape * m_Obj = new ShapRectangle();
// return the created function
return m_Obj;
// =========== this is ShapCircle .dll
//==========================ShapCircle .h
#include "MyIShape.h"
class DLL_API ShapCircle :public CMyIShape
public:
ShapCircle(){};
virtual ~ShapCircle(){};
virtual void Fn_DrawMe(){/*something here */};
virtual void Fn_GetRadious(){/*something here */};
__declspec (dllexport) CMyIShape* CreateShape()
// call the constructor of the actual implementation
CMyIShape * m_Obj = new ShapCircle();
// return the created function
return m_Obj;
in exe there is no include header of of ShapCircle and ShapRectangle
and from the exe i use LoadLibrary and GetProcAddress .
typedef CMyIShape* (*CREATE_OBJECT) ();
CMyIShape*xCls ;
//===================== from ShapeCircle.Dll
pReg= (CREATE_OBJECT)GetProcAddress (hInst ,"CreateShape");
xCls = pReg();
now xCls give all access of base class. but how to get pointer of funciton Fn_GetRadious() or how to get access.
thanks in advance.

could you please tell me in detail. why so. or any reference for it. i love to read.
i don't know this is bad way.. but how? i would like to know.
I indicated in the second sentence. Classes can be implemented differently by different compilers. For example, the alignment of member variables may differ. Also there is the pitfall that a class may be allocated within the DLL but deallocated in the client
code. But the allocation/deallocation algorithms may differ across different compilers, and certainly between DEBUG and RELEASE mode. This means that you must ensure that if the DLL is compiled in Visual Studio 2010 / Debug mode, that the client code is also
compiled in Visual Studio 2010 / Debug mode. Otherwise your program will be subject to mysterious crashes.
is there any other way to archive same goal?
Of course. DLL functionality should be exposed as a set of functions that accept and return POD data types. "POD" means "plain-ole-data" such as long, wchar_t*, bool, etc. Don't pass pointers to classes.
Obviously classes can be implemented within the DLL but they should be kept completely contained within the DLL. You might, for example, expose a function to allocate a class internally to the DLL and another function that can be called by the client code
to free the class. And of course you can define other functions that can be used by the client code to indirectly call the class's methods.
and why i need to give header file of ShapCircle and shapRectangle class, even i am not using in exe too. i though it is enough to give only MyIShape.h so with this any one can make new object.
Indeed you don't have to, if you only want to call the public properties and methods that are defined within MyIShape.h.

Call function inside running class

Hey All,
i have a two question in classes.
1- i have class and i called its before and its running on runtime. i need to call function inside this class from another class, but without call the first one again, because if i called it, it will run default class function again
is this doable ?
2- What super() mean ?
Thanks a lot.

this is the default call, and when i call the method by this way its will run the default class function before call the method.
here my example:
i need to call checkboxes function in ChannelsMain class without pass by the grey script.
Note: the call_cb is working and the trace is working
so i now the class is running, i need to call the checkboxes without ( var ci:YourClass = new YourClass(); )
package com.link
     import fl.controls.CheckBox;
     import flash.events.*;
     public class ChannelsMain
          var cbLength:uint = Main.PV.channel_id.length;
          public function ChannelsMain()
               // constructor code
               for (var i:int = 0; i < cbLength; i++)
                    var cb:CheckBox = new CheckBox;
                    cb.name = Main.PV.channel_id[i];
                    cb.label = Main.PV.channel_name[i];
                    cb.x = 50;
                    cb.y = 50 + i * 30;
                    cb.addEventListener(Event.CHANGE,call_cb);
                    Main.MS.addChild(cb);
                    //call xml function
                    if(i == cbLength - 1)
                         new ChannelsXML();
          private function call_cb(evt:Event)
               trace(evt.currentTarget.name,evt.currentTarget.selected);
          public function checkboxes(evt)
               trace(evt);

Call function from data base with clob input parameter.

Hello,
In this project I use Jdev 11g.
I call function from database.
create or replace function get_fa_list (
p_fa_id_list in clob
return sys_refcursor
is
vCursor sys_refcursor;
begin
put_msg ('begin');
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;
put_msg ('Save');
open vCursor for
select rownum as id, s.*
from (
select f.latitude, f.longitude, count (distinct f.res_id) as res_count, count (*) as fa_count, 16711680 as color, res_concat_distinct (f.res_id) as station_list
from mv_frequency_assignment f, table (SplitClob (p_fa_id_list, ',')) l
where f.ext_system = 'BI' and
f.ext_sys_id = l.column_value
group by f.latitude, f.longitude
) s;
put_msg ('Open and End');
return vCursor;
end get_fa_list;
I use TopLink in ejb.
i use follow code for call function and get result.
public List<TmpResPoints> findAllPointsBI(String p_id){
UnitOfWork uow = getSessionFactory().acquireUnitOfWork();
uow.beginEarlyTransaction();
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("get_fa_list");
call.useUnnamedCursorOutputAsResultSet();
ClobDomain c = new ClobDomain(p_id);
//System.out.println(c.toString());
call.addNamedArgumentValue("p_fa_id_list", c);
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(TmpResPoints.class);
query.setCall(call);
List<TmpResPoints> result = (List<TmpResPoints>)uow.executeQuery(query);
uow.commit();
uow.release();
return result;
But size parameter "p_fa_id_list" is 0. (geting from temp table in Data base). this code in function >>
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;)
How I can call this function from dataBase and get result?
thx,
Demka.

What is the SQL generated?
The argument should just be the Clob value (a String) not the domain object.
Also try addNamedArgument, and then pass the named argument to the query.

How to Call Function from SAPSCRIPT

I want to Call a function from my SAPSCRIPT to get some data and print the same in the form , Can I get an example for this

Hi Nandan,
U cannot directly call function from SAPScript... For that u have to create one include in which u need to write the code. Using Perform... EndPerform u can call the same from SAPScript. See the below example
u need to write this code in SAPScript
PERFORM formname IN PROGRAM includename
USING &field1&
USING &field2&
CHANGING &field3&
ENDPERFORM
Here includename is your include type program.
u need to write this code in your include type program..
FORM formname TABLES in_par STRUCTURE itcsy
                        out_par STRUCTURE itcsy.
data : var1 like field1,
       var2 like field2,
       var3 like field3.
READ TABLE in_par WITH KEY 'field1'.
CHECK sy-subrc = 0.
var1 = in_par-value.
READ TABLE in_par WITH KEY 'field2'.
CHECK sy-subrc = 0.
var2 = in_par-value.
now u can call corresponding function using local VAR1 and VAR2. Here u can pass N no of USING parameters.
After processing on VAR3...
READ TABLE out_par WITH KEY 'field3'.
out_par-value = VAR3.
MODIFY out_par INDEX sy-tabix.
EndForm.
Here in_par and out_par are the structures which will be used to communicate with SAPScript. And this is the only way as per my view.
I m sure this code will work fine. Here i have used dummy variables that u need to change as per your requirement. If u have more queries write me back.
And yes if this works than dont forget to give the points.
Regards,
Sagar

Is it possible to call methods from another class from within an abstract c

Is it possible to call methods from another class from within an abstract class ?

I found an example in teh JDK 131 JFC that may help you. I t is using swing interface and JTable
If you can not use Swing, then you may want to do digging or try out with the idea presented here in example 3
Notice that one should refine the abstract table model and you may want to create a method for something like
public Object getValuesAtRow(int row) { return data[row;}
to give the desired row and leave the method for
getValuesAt alone for getting valued of particaular row and column.
So Once you got the seelcted row index, idxSelctd, from your table
you can get the row or set the row in your table model
public TableExample3() {
JFrame frame = new JFrame("Table");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}});
// Take the dummy data from SwingSet.
final String[] names = {"First Name", "Last Name", "Favorite Color",
"Favorite Number", "Vegetarian"};
final Object[][] data = {
     {"Mark", "Andrews", "Red", new Integer(2), new Boolean(true)},
     {"Tom", "Ball", "Blue", new Integer(99), new Boolean(false)},
     {"Alan", "Chung", "Green", new Integer(838), new Boolean(false)},
     {"Jeff", "Dinkins", "Turquois", new Integer(8), new Boolean(true)},

Calling a JavaScript function from my class

Here's the situation. I am trying to access a website (not my own) through a class I am writing. Some information that I need to pull off the page can only be seen when a JavaScript function is called. How can I make the page call the function from my own computer?

Well, you could use a tool like this:
http://httpunit.sourceforge.net/
If the Javascript you want to call into is relatively simple it may work ok for you, but there's no guarantee - differences between the browser's libraries and the Rhino (Java's embedded Javascript) libraries may make the exercise intractable.
You might alternatively be able to invoke the browser from Java and then screen scrape it somehow, but I can't help you with that - and it's a distinctly inelegant solution.
If you have a legitimate reason for doing this, your best bet would be to contact the website owner and see if they can accommodate you somehow; they may even have a suitable services API for you to call into without messing about trying to render the Javascript. If you don't have a legitimate reason for doing this (one the website owner would be ok with) then my sympathy for your plight is rather limited anyway.

Put SQL query in a function/ call function from region

How can I write a SQL query (like SELECT EMPNO, ENAME, JOB FROM EMP) as PL/SQL function, and then call this function from the PL/SQL Function Returning SQL Statement region?
Thanks, Tom

thanks jverd for your quick reply.
I know passing in a reference to an object will do the job if I want to change the value several parameters in one function call.
But I want to ask, is there any other ways?
the following code works.....
public class TestParameter {
     public static void main(String[] args) {
          Test2 t2 = new Test2();
          invokeChange(t2);
          System.out.println("x = " + t2.x + "\t y = " + t2.y);
     static void invokeChange(Test2 t2) {
          t2.x = 10;
          t2.y = 15;
class Test2 {
     int x;
     int y;

Calling PopUpManager from a class in a library

I have a class for logins that I have put in a Flex Library
Project.
Part of the login is a popup form(mxml) I have created and is
in the library.
The problem I have is this line:
loginPopUp =
LoginForm(PopUpManager.createPopUp(this,LoginForm,true));
The error I get is:
1067: Implicit coercion of a value of type
dataManagers:LoginManager to an unrelated type
flash.display:DisplayObject.
The parent “this” is no good since its parent
should be the application that called the logon.
Can I reference the caller from the LoginManager class I
created to feed to popupmanager as the parent for the popup?
The code in the app using the llibray that relates to this
(to save space) is:
import dataManagers.LoginManager
public var lm:LoginManager = new LoginManager();
lm.initServices();
//LoginManager.as
package theLoginManager {
import flash.events.Event;
import mx.managers.PopUpManager;
public class LoginManager {
import LibraryViews.Login.LoginForm;
public var loginPopUp:LoginForm;
public function initServices() : void
Alert.show("Login start");
appCFC = new RemoteObject("ColdFusion");
appCFC.source = "CFC.Users.usersGateway";
appCFC.addEventListener(FaultEvent.FAULT, server_fault);
appCFC.init.addEventListener(ResultEvent.RESULT,init_result);
appCFC.getById.addEventListener(ResultEvent.RESULT,getById_result);
displayLogin()
private function displayLogin():void{
loginPopUp =
LoginForm(PopUpManager.createPopUp(this,LoginForm,true));//THIS IS
THE PROBLEM LINE
loginPopUp.addEventListener("loginSuccessful",

I solved it by passing the parent when I called it from the
parent project:
lm.initServices(this);
and then created a var in the .as file:
private var theCallingParent:DisplayObject;
theCallingParent = theParent;
Then used that variable when I called the popup:
loginPopUp =
LoginForm(PopUpManager.createPopUp(theCallingParent,LoginForm,true));
Sorry to clog up the board.

Call function from action panel in second frame

I am starting to learn Adobe Flash. I'm using Flash CS6.
I have a file called test.fla and another called bikertest.as
Bikertest has this code:
package as3.grey{
import com.grey.utils.Console;
//import com.grey.utils.ClickTag;
import flash.display.MovieClip;
import com.greensock.TweenNano;
import com.greensock.easing.*;
import flash.events.*;
public class bikertest extends MovieClip {
private var mc:MC;
private var console:Console;
public function ray():void{
init();
trace("hi from here");
mc=new MC
; addChild(mc);
I tried:
import as3.grey.bikertest.as;
var t = new bikertest();
t.ray();
I want to be able to call ray() from the Action Panel in the second frame in test.fla . I hope this is clear. How can I do that? /Thanks!

assuming your fla is in a super directory of as/grey and everything in bikertest is defined, use:
import as3.grey.bikertest;
var t:bikertest=new bikertest();
t.ray();
