Can javascript call applet methods in explorer??

Is it possible to call the start() and stop() methods of an applet in explorer 5? I know how to do it using netscape, document.appletname.start(); and that works, but I just get errors in explorer. Any suggestions?

The code I used was:
document.appletname.stop(); or
document.applets["appletname"].stop();
Neither worked, I just got this error:
"Object doesn't support this property or method"
but I know the applet has a stop() method because I wrote it!

Call applet methods from Javascript

Hello,
If I call applet method like :
function callbackFunc(){
var pp = appletID.getData();
alert(pp);
It works only if applet is deployed with <APPLET> tag or with javascript.
If applet is deployed using <Object> and <embed> tags, in browser console the error is :
TypeError: appletID.getData is not a function
I couldn't find why is that behaviour. What do I do wrong?
Thanks

Hi Paul,
(1)Seems to be your Java Runtime Environment path is still setted for JRE 1.3.0_01 and not for 1.3.1. So pelase go to the
Control Panel-->java plugin 1.3.1-->Advanced. Here you set the Java Runtime Environment to the JRE 1.3.1 version. Its better to remove the older version before installing the new version on JRE.
(2)<OBJECT> tag won't work for Netscape. You can only use <APPLET> or <EMBED> tag for Netscape.
Hope this will help you.

Hi,
The purpose of service locator is to abstract the lookup of the server side services like ejb and DSNs. It should be a normal java class but as such there is no such restriction. You can have a look at the service locator patter at the j2ee blue prints.

Please help me to resolve this....
Regards,

You can not directly call view's event handler from other component.
create a method in component controller of the second component and in the button click call the component controller method. ( also make the method as interface so that you can call it from other components )
Now, you can call the interfacecontroller's method
DATA: l_ref_INTERFACECONTROLLER TYPE REF TO ZIWCI__VSTX_REBATE_REQ_WD .
l_ref_INTERFACECONTROLLER =   wd_This->wd_CpIfc_<comp usage name>( ).
l_ref_INTERFACECONTROLLER->Save_Rr(
    STATUS = '01'                       " Zvstxrrstatus
save_rr is the method of second component controller

Call applet method with javascript

Directly calling a Java Applet's public method from within
JavaScript is made possible by LiveConnect which is not implemented by Internet Explorer as of yet. LiveConnect is only available on Netscape navigator at this time.

Call Applet method from JavaScript, tiny test program works... SOMETIMES!?

I have an embedded Applet in a web page, and I am trying to directly call a method in that Applet from the same page, using JavaScript.
Here is the complete Applet:
import java.applet.Applet;
public class Test extends Applet {
public String test() {
return "test() method return value";
}Here is the complete web page:
<HTML>
<HEAD><TITLE>Applet Invocation test</TITLE></HEAD>
<BODY>
<APPLET CODE="Test" WIDTH=10 HEIGHT=10 NAME="test"></APPLET>
<HR>
<SCRIPT>
document.write( "JavaScript is working<br>" );
document.write( document.test.test() );
</SCRIPT>
</BODY>
</HTML>Is there anything wrong with this? Because it works about 15% of the time, displaying an <HR>, "JavaScript is working", and then "test() method return value" on the next line.
The other 85% of the time, it just gets to "JavaScript is working", then I get a JavaScript error "Object does not support this property or method" for the line: document.write( document.test.test() );
Now here's another weird quirk... I can get it to work ALL the time, if I delay the execution of the Applet method. For example, if the first line after <SCRIPT> is alert( "alert" ); then the user gets a little dialog box with "alert" message in it, and when they hit OK execution continues, and the applet method call ALWAYS works. (On a side note, if I make the Applet test() method static, it NEVER works. Why is this?)
So it seems to me, that when it is failing, it is because the Applet is not completely loaded into the browser yet. My question is, how can I get around this?? Is there a way to instruct JavaScript to wait until the Applet is finished loading before attempting to call any methods on it?
PS I am using Windows ME and IE 6

Thanks for the reply, I appreciate it. I have another question, if you don't mind... here is what my new test web page looks like:
<HTML>
<HEAD>
<TITLE>Applet Invocation test</TITLE>
<SCRIPT>
function testFunc()
document.write( document.test.test() );
</SCRIPT>
</HEAD>
<BODY onLoad="testFunc()">
<APPLET CODE="Test" WIDTH=10 HEIGHT=10 NAME="test">
</APPLET>
<HR>
</BODY>
</HTML>What happens is: the page loads, I see a 10x10 grey applet box, and a <HR>... then a split second later, onLoad is fired, and everything on the page so far is REPLACED with the output of testFunc(), so the ONLY thing on the page after this all completes is "test() method return value"
Why is a single document.write() statement CLEARING the page before outputting? I don't understand. If calling a document.write() from an onLoad event wipes out everything on the page, this is not extremely helpful solution.

Call applet method with arguments from JavaScript

I have an applet with a method doSomething(int a, String b, double c), I want get a,b,c from threee text fields put into an HTML page, and pass them to the applet method. I've a very poor knowledge in JavaScript, how can I pass correctly the arguments without raise a CastException? It seems to me that JavaScript doesn't have int, String, double.....

Hi!
You can verify before you send the parameters to the applet
Something like that:
var result = parseInt (a);
if (result =NaN)
alert("Sorry not Int");
return false;
and after that you can send the parammeters to the applet that way:
document.yourApplet.Your_function_from_applet(result,..)
hope this help!

Problem calling applet method using IE

I've searched through the forum and can't seem to find anything that can help me fix this. I'm trying to call an applet's method using Javascript. This is working fine under Netscape, but not IE. Everything I've read seems to indicate that I'm doing this right, but I'm getting "Object doesn't support this property or method" when I try to call the applet method from IE.
In this example method, I'm trying to call the applet's countChars method, which should return the length of the string you pass into it. Works under Netscape 6.2, but not IE 6.0
Here's my applet code:
import java.lang.String;
public class test extends java.applet.Applet {
public static int countChars(String s) {
return s.length();
And my HTML
<HTML>
<HEAD>
<script language="Javascript">
function refreshApplet()
/*     i = document.forms.myForm.TestApplet.countChars();
     document.forms.myForm.output.value=i; */
     document.forms.myForm.output.value=document.applets["TestApplet"].countChars(document.forms.myForm.input.value);
</script>
</HEAD>
<BODY>
<APPLET CODE = "test.class" WIDTH = 400 HEIGHT = 400 ALIGN = middle NAME = "TestApplet" scriptable="true">
</APPLET>
<br>
<form name="myForm">
<input type="text" name="input">
<input type="button" value="click me" onClick="refreshApplet();">
<hr>
<input type="text" name="output">
</form>
</BODY>
</HTML>
Thanks in advance!

This is my code:
- I call the applet using javaScript and input the method setData with two strings.
function graphic()
     var dataZenith;
     var dataManual;
     initVariables();
     dataZenith = graphicZENith(); //Call other Javascript functions
     dataManual = graphicManual(); //Call other Javascript functions
     document.AppletOne.setData(dataZenith,dataManual);
I run the applet with this HTML code:
<applet NAME="AppletOne" code="Appl.class" width="450" height="450"
MAYSCRIPT></applet>
//Applet code/////////////
import java.awt.*;
import java.awt.geom.*;

                    for (int i = 0; i < 156; i++)
                    myArray1[i] = Integer.parseInt(theTokens1.nextToken().trim());
                    myArray2[i] = Integer.parseInt(theTokens2.nextToken().trim());

How can I call a method for all instances of a certain class?

Hi,
I have created a snake java applet, which you can play here [http://users.telenet.be/javagames/|http://users.telenet.be/javagames/].
But now I want to make this into a multi-player game (with two or more snakes etc..).
In my main class you can find methods like these:
snake.move();
snake.drawSnake();Now if I just alter my main class and make a second instance of the class snake and change my methods to this,
snake.move();
snake2.move();
snake.drawSnake();
snake2.drawSnake();my game almost works perfectly, I'll have to make some minor changes though.
But my question is, is there a better way of doing this. Instead of duplicating all the code, how can I make the methods immediately work for both snakes, instead of calling it twice?
All suggestions are welcome!
Thanks in advance.
Lennart

If there was something common to all snake instances then you could declare that variable static.
Note: I don't want to confuse you here. A static variable can have a value apart from any instances at all. Instances can view static variables but a static method or inner class, for example, cannot view instance variables.
More generally, I would think you would want to treat each snake as an automaton with its own behavior. There must be some class such as Game or Board or whatever that has, as suggested, either an array or collection of snakes. Iterate over each snake, ask it to perform some computation for the game and then draw itself.

Can I call applet in other applet???

1.Just like a call a frame in new window.....can i call a frame in the same window.
2.Can i call an another applet in the same window from a running applet.if yes how can i send any variables to it??

Your first question is not really clear to me, but the second I got. You can have an applet call another applet, you need to use getApplet or getApplets (which return Applet and Applet[] respectively). If you use getApplet you need to name your applets, while getApplets just returns every single applet on the page.
Then, when you have Applet myOtherApplet = getApplet("Applet2");
You can do myOtherApplet.method(int parm1, String parm2);
Applets are named in the html file, don't remember the correct syntax right now.

Calling applet methods in forms - Problem

I have an applet method wich creates a modal dialogue to retrieve user pin. This method is called from a form button. When the user is finished entering PIN, and the dialogue is supposed to close, it hangs. When using a button in an applet frame, this works fine, but apparently it doesent when I use my form button. Anybody have a workaround or solution to my problem?

i guess the problem is that you can't do anything in the applet outside the dialog if it is modal and visible.
Propably you should not make your dialog modal and just let it set a boolean variable when it is finished and keep the rest of the applet waiting for an answer with domething like:
while(dialogstillopen)
boolean dummy=false;

Javascript call Actionscript method cross domain

we have moved our flash app to a cdn. i have javascript
calling an actionscript method. it worked fine when our files were
on the same server, but now the swfs are being served from a
different server.
in firefox, i receive the following error
uncaught exception: Error calling method on NPObject! [plugin
exception: Error in Actionscript. Use a try/catch block to find
error.].
any help would be appreciated!

OK, so the _api REST services now supports ODATA batching, but unfortunately it has a bug in it: it does not respond to changesets in a batch in the correct format. Microsoft's own datajs library (http://datajs.codeplex.com/) cannot
parse the response. See Andrew Connell's blog post:
http://www.andrewconnell.com/blog/part-2-sharepoint-rest-api-batching-exploring-batch-requests-responses-and-changesets
So until this bug is fixed I would still like to access the ListData.svc in the host web using a cross-domain call. Does anybody know whether the SP.RequestExecutor supports this scenario: that is initialising the SP.RequestExecutor with the url for
the host web, not the app web. If not, what is the point of the cross-domain library?
