Access private variables from javascript
Hi.
How can i access my objects and varibles, in my java code from my javascript.
Try displaying the value before you assign it.
If you wanna display the value of a text field called textCallClass, this is the javascript code:
alert(document.getElementById("form1:textCallClass").value);
And if you wanna display a field called uniqueNum from a page called
SchemeHolders, this is the javacsript code:
alert(#{SchemeHolders.uniqueNum});
You have ro have a public function called getUniqueNum in SchemeHolders.java. And ensure the case is exactly like mine is.
That does work fine in my programs, if you have any other problems, post the error message.

How can I access xml document from javascript whithin a JSP page
how can I access xml document from javascript whithin a JSP page?
I have a JSP that receives an XML document from a JavaBean, so I can access it within the entire JSP, but I need to access it from the javascript inside the JSP... and I have no idea how i can do this.
Thanks in advance!The solution would only work on MS IE browsers, as other browsers do not support an XML DOM.
It can be done, but you would be stuck with using the Microsoft broswer. If that is acceptable, I have some example code, and a book recommendation. -

I am using jdk1.5 for my development...
Can anyone help to resolve this security issue. Urgent...
Thanks in advance.Hey thanks. I wasn't able to get it to work with that sample but I did find this very similar code that does allow javascript to call JFileChooser in an applets public method.
java.security.AccessController.doPrivileged(
new java.security.PrivilegedAction()
public Object run(){
//do your special code here
return null; //return whatever you want
It seems a bit tempermental in that if you don't select a file quickly, it will hang the browser....no perfect solution but I'm going in the right direction.
Thanks,

Accessing a private variable from a public method of the same class
can anyone please tell me how to access a private variable, declared in a private method from a public method of the same class?
here is the code, i'm trying to get the variable int[][][] grids.
public static int[][] generateS(boolean[][] constraints)
private static int[][][] sudokuGrids()
int[][][] grids; // array of arrays!
grids = new int[][][]
{Are you sure that you want to have everything static here? You're possibly throwing away all the object-oriented goodness that java has to offer.
Anyway, it seems to me that you can't get to that variable because it is buried within a method -- think scoping rules. I think that if you want to get at that variable your program design may be under the weather and may benefit from a significant refactoring in an OOP-manner.
If you need more specific help, then ask away, but give us more information please about what you are trying to accomplish here and how you want to do this. Good luck.

Accessing c4 Variables in Javascript
How do you pass a Captivate 4 variable (User or System) in Javascript when the published .SWF is embedded in another tool like Lectora or Flash?
In Captivate, you can set a value into a Lectora variable (VARmyLectoraVariable.set('myvalue');, but I don't know how to access the Captivate variable.
When run from Captivate, this works:
Captivate.GetVariable('CaptivateVariable');
But when the published .swf from Captivate is inserted into Lectora and run, I get a JavaScript error ('Captivate' is undefined).
How do you reference the Captivate variable in JavaScript when the .swf is not embedded in the Captivate project html file?
Thank you!http://pipwerks.com/journal/2009/06/07/introducing-the-captivatecontroller/

Access PageFlowScope variable in JavaScript
Hello,
I need to access the pageflow scope variable inside a Javascript on window.onbeforeunload event in Jdev11g.
Any pointers?Hi,
tecnically PageFlow scope is a Map in sessionScope and this not accessible from JavaScript. What you can do
- use clientListener to invoke JavaScript method which the invokes a serverListener to call a managed bean
- have the managed bean accessing the pageFlo scope attribute
- have the managed bean calling back the client by executing JavaScript using the ExtendedRenderer Kit as explained in chapter 5 of http://download.oracle.com/docs/cd/E15523_01/web.1111/b31973/toc.htm
As John said, the use case would be good to learn about because information can also be added on clientAttributes (af:clientAttribute)

I'm a little confused. I know that using private instance variables is good practice, and that the appropriate way to access those variables is with accesser methods (getXXX(), etc.). Since the variables are private, you can't access them by just referring to "testClass.variable", right?
Well, I was reading up on the Comparable interface today, and found a code example where a class implemented a compareTo() method like this:
public int compareTo(Object o) {
if (privateVariable < (TestClass) o.privateVariable) {
return -1;
} else {
return 1;
}But privateVariable is declared as a private variable. So why is it that you can refer to o.privateVariable in the compareTo() method? Is it just because o is cast as a TestClass object, and the compareTo() method is inside of the TestClass class? Even if that's the case, it still seems weird to me; if privateVariable is declared private, I'd think that any reference to a TestClass.privateVariable variable would throw an exception, even if the reference is within the TestClass. This just seems different to me than referring to the privateVariable variable within TestClass, because that obviously refers to the member of the current instance, not a different instance.
Anyway, any explanation would be appreciated.
RichYes, 'private' means 'private to this class', not 'private to this object'.
In this way, it behaves somewhat like a 'friend' variable. The basic idea of making variables private is to hide the implementation behind a class, which still holds even with the compareTo method (you can't use it to figure out that there's a variable called 'privateVariable', when using it from outside your class.) -
How to access a variable from within a symbol.
How do I access a variable set outside a symbol from within that symbol?
ThanksIf you set a variable on stage ,say
sym.setVariable("stageVariable", "I am stage variable");
You can access it from within a symbol using :
var myVariable = sym.getComposition().getStage().getVariable("stageVariable");
Basically you need to get handle to the symbol in which the variable is defined. -
Is there any way at all of accessing captivate variables from flash?
Hi,
I would be grateful for any help on this one. I have been working in flash and I wanted to know whether there is any way at all of calling/accessing captivate 4 variables from flash (I'm working in flash Cs4 Actionscript 3.0 and I'm trialling Captivate 4, but I just want to know whether there is any way/method of communicating between a flash file and a captivate 4 file, and if so, can this be done with an embedded captivate 4 file/swf). Surely there must be a way of communicating between the two - they are both Adobe products!
Thanks for any help, pointers, advice, tips in advance.Hi Louon,
Don't know if this would help you.

Access payroll variables from custom payroll function
Hi All,
I have a requirement to create a custom payroll function that returns some data from IT0006 and IT0032.
I have written the code in PCBURZDE0, as the payroll is for Germany, it does read the data needed.
My question is, how I can access the variables specified for the function in the payroll schema.
Schema definition in PE01
Zeile Fkt Par1 Par2 Par3 Par4 D Text
000010 BLOCK BEG Fahrradleasing
000020 _DFRD &PRO GEN
000030 BLOCK END
If I double-click Par1 for function _DFRD (&PRO), then I see he two variables I should write the data to:
Zeile VarArg. FZ T Operation Operation Operation Operation Operation Operation *
-------------+---------+------------------+---------+---------+---------+---------+
000010 AMT= PKWWRPRINT *
000020 1 AMT= ENTKM PRINT
So, as I understand I should write the two variables PKWWR and ENTKM, I have the values in the function code, but I don't know how to access these variables.
Thanks for your help!
Gyöngyi1 - PIT is a Function that is used in the Payroll Schema to "Process the Internal Table".
2 - You mentioned that you had created a Custom Function to read IT0006 and IT0032, and I only suggested to you that you could have that Custom Function generate Information WageTypes and save them in the Input Table where they could then be used in PCRs.
3 - I did not mention that you can read only one value through operation AMT, but I mentioned that using AMT=xxxxxx followed by AMT=yyyyyy means that the first statement is useless. On the other hand, using AMT=xxxxxx followed by AMT+yyyyyy and AMT+zzzzzz will result in the amount being the total of the 3 values.
4 - Please read some documents on Schemas, Functions and PCRs, such as in the Wikis on this site, and study your current Payroll Schema, it's sub-schemas, it's functions and the operations in it's PCRs. Note that t-code pe01, pe02 and pe04 can be used to find some documentation on functions and operations.
