Invoking Applet methods from Javascript for Netscape 6

Hi,
I am trying to invoke an applet method from javascript, but it is failing with Netscape 6 browser:
I am doing it the following way-
function test(form)
var i = document.myapplet.getname();
where myapplet is the name of the applet and getname is a method within the applet. This is
working with Ie but not with netscape 6.
I would appreciate it if someone could tell me how should I invoke the applet method for netscape browsers.
Thanks.
Jay Srin.

Not working with NS 6 - and will not i guess till they upgrade to Mozilla Version 1.0 - Live Connect is not implemented 100% correct yet - if you want you can download the 7.0 Pre Release Netscape - since its using mozilla 1.0 it should work , see :

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.

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 to Applet Method from JavaScript Failed.

I Am calling a method from a javascript function from within a web page.
The page is loaded into a frame. The parent window of the frame has stored a reference to the applet which defines the methods. Note I am treating the reterence to the applet as a global variable. So that I can reference it methods as I navigate from one page to another.
I have JavaScript objects defined, and I am passing them as parameters to the applet's methods. In java, the JavaScript objects are refererenced as JSObject. When I call a java method passing a JavaScript
Object I get the following exception. Note Iam using j2sdk1.4.2_01 on a Windows 2000 Professional System. This problem start occurring after the recent Microsoft Worm/Virus a fix was loaded on my system which resulted in the following bug. Could someone please help me.

A little code snippet would help. I use JSObjects from Java 1.4 no problem and do have all the latest updates. I also have JavaScript calling Java code as well - also with no problem.

Accessing Signed Applet Method From Javascript

Hi All,
In my intranet application i have to retrive the mac addres of the client using the applet. I have to capture the MAC Address and set it as a hidden value in the jsp page.
I have used the signed applet and able to retrive the mac address of the client using IE but I am not able to do the same on NN 7.1
Below is my javascript and the applet tag syntax, please help me if i am wrong anywhere
function mac()
var mval=document.myApplet.getWinMACAddress()
alert("addres" +mval)
document.loginform.js_value.value=mval
and the applet tag in my jsp page is
<applet code ="SignedAppletDemo.class" codebase="http://mysouthasia/AcadResource/jsp/" archive="SSignedApplet.jar" width=1 height=1 align=center name="myApplet" >
</applet>
Thanks in Advance

Since getWinMACAddress( ) seems to work just fine for IE, is there an equivalent for NN7.1?
What happens if I run Opera instead, and on a Linux system? Or Safari on OS X? Obviously getWinMACAddress( ) isn't going to work for that.
I really don't understand why so many Asian programmers get "Find the MAC address of..." as a homework assignment. There are many reasons why it isn't really practical to do so, and for examples, just search this forum for MAC addresses. Lots and lots of examples and counter examples.

How to call jpf controller method from javascript

Can any one help me how to call pageflow controller method from JavaScript.\
Thanks.

Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
document.getElementById("batchForm").submit;
2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
document.getElementById("ACTION_NAME").value = "UPDATE";
document.getElementById("batchForm").submit.
Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
This entire lines of code should do what we want.
<netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>
<netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
<c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
<%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
<netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
</c:forEach>
</netui:select>
See if you can build along those above lines of code. Any other simpler approches are highly welcome.
Thanks

In the 6.1 client, I've established a WebServiceProxy and set the userName and password to the proper values, but I can't seem to get past the security.
If there something special I need to do on either the 8.1 securing side or on the 6.1 accessing side to make this work?
Any help would be GREATLY appreciated.

Invoking java methods from C/C++ on the machine with different JREs

I implemented Windows NT Service instantiating JVM and invoking several java methods. Everything works but I have an issue with running the service on the machine where multiple different versions of JRE have been installed. The service is calling java methods that require JRE 1.3 or later so I wrote the code that is setting system PATH from within the service based on the configuration stored in the external file. The problem is that the service requires jvm.dll to be in the PATH prior lunching it since this library is instantiated through the implicit linking. When I put jvm.dll in the same path as the service binary I can lunch it but JNI_CreateJavaVM fails and returns -1. This happens even if JRE 1.3 is in the system PATH prior lunching the service.
Everything works if the system PATH contains references to JRE 1.3 and jvm.dll is removed from the service's directory.
I am looking for an advice on what is the proper way to deal with invoking java methods from the C/C++ executable in the environment with different versions of JRE.
Thanks, Kris.

Here's a way I have done what you are asking about:
What you want to do is make all of your linking happen at runtime, rather than at compile time. This way, you can edit the PATH variable before the jvm.dll gets loaded.
Following is some code that I used to handle a dll of my own in this manner. You can decide if you want to write a "wrapper" dll, or if you find it simpler to approach the jvm.dll in this way.
// Define pointer type for DLL entry point.
     typedef void JREPDLL_API (*EXECUTEREQUEST)(char*, Arguments&);
// Set up path, load dll, and pass everything off to it.
HINSTANCE javaServer = javaServer = LoadLibrary("jrepdll.dll");
if (javaServer != NULL) {
EXECUTEREQUEST executeRequest = (EXECUTEREQUEST)GetProcAddress(javaServer, "ExecuteRequest");
if (executeRequest != NULL) {
if (argc == 1)
     // Execute the request.
     executeRequest("-run", args);
else
     // Execute the request.
     executeRequest("-console", args);
Here's some code for how to edit the PATH:
          // Edit the PATH environment variable so that we use our private java.
char *appendPt;
char *newPath;
char *path;
          char tmp[_MAX_PATH];
          // Get the current PATH variable setting.
path = getenv("PATH");
          // Allocate space for an edited path setting.
          if (path != NULL)
               newPath = (char*)malloc((_MAX_PATH * 2) + strlen(path));
          else
               newPath = (char*)malloc((_MAX_PATH * 2));
          // Get upper part of path to desired directories.
          strcpy(tmp, filepath);
          appendPt = strstr(tmp, "dbin\\jreplicator");
          appendPt[0] = '\0';
sprintf(newPath, "PATH=%sjava\\jre1.2.2\\bin;%sjava\\jre1.2.2\\bin\\classic", tmp, tmp);
// Append the value of the existing PATH environment variable.
// If there is anything, append it.
if (path != NULL) {
     strcat(newPath, ";");
     strncat(newPath, path, (sizeof(newPath) - strlen(newPath) - 2));
// Set new PATH value.
_putenv(newPath);
          free(newPath);

How to access the controller method from javascript onclick event?

Hi All,
I am totally new to development. And I got struck in calling a controller method from javascript function.
I have no idea about ajax and all those things. Please can anyone help me to solve this issue!
Thanks in advance.

Hi,
As I know, you can use jQuery to do this, here is an example.
Example of your Controller Method.
[HttpPost] // can be HttpGet
public ActionResult Test(string id)
bool isValid = yourcheckmethod(); //.. check
var obj = new {
valid = isValid
return Json(obj);
and this would be your javascript function.
function checkValidId(checkId)
$.ajax({
url: 'controllerName/Test',
type: 'POST',
contentType: 'application/json;',
data: JSON.stringify({ id: checkId }),
success: function (valid)
if(valid) { //show that id is valid }
else { //show that id is not valid }
If you have further issues, I would suggest you move to MVC forum, it is appropriate and more experts will assist you.

How to invoke action method from mail contained link

Hello,
my application needs to send mails to users that include links for the user to click on. Something like www.mysite.com/displayData.jsp&id=123. My question is now how I make JSF invoke the respective method in the backed bean to display the data with the id 123 when the user clicks on the link int the mail.
I wonder whether there is some kind of "catch-all action" that checks whether the user is logged in and authorized whenever any JSP page is invoked. I'm a bit tired of first checking the authorization of some user before processing the remaining part od the backed bean's action method.
Thanks for any hints,
Oliver Plohmann

Call Java method from JavaScript

Hi,
I have a Java class called abc.java and in that I have a method called assignValue(String value).
I need to call this method, assignValue() , from JavaScript.
Is there a way to call a Java method from JavaScript.
Any help is greatly appreciated.
Thanks.

Yes I did, and I still don't get it, I have created a JSF web application, not an applet, as I posted earlier my code to executes sit's in a class file, not an applet file.
My Page1.class file is as follows
* Page1.java
package a1;

public class Page1 extends AbstractPageBean {
    public void valset(int val) {

Hi,
Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.

Is it possible to invoke JEB method from thread?

Hello everybody!
I have problem creating EJB from the thread. Here is the part of code below:
public void email() throws Exception {
class MailThread implements Runnable {
public MailThread() {
public void run() {
try {
String jndiName "java:comp/env/ejb/PROG/Mail";
IMailHome mailHome;
IMail mail;
InitialContext context = new InitialContext();
Object objref = context.lookup(jndiName);
mailHome = (IMailHome) PortableRemoteObject.narrow(objref, IMailHome.class);
// Exception here:
// java.rmi.RemoteException: Exception Substitute; nested exception is:
// java.lang.NullPointerException mail = mailHome.create();
// business metods
// mail.method1();
} catch (Exception e) {
System.out.println("Exception:" + e);
MailThread mt = new MailThread();
Thread thread = new Thread(mt);
thread.start();
Exception:
java.rmi.RemoteException: Exception Substitute; nested exception is:
java.lang.NullPointerException
I am not able to create EJB instance from the thread. The same code works well in servlet. Am I doing something wrong?
May be there are some different approaches to implement some operations asynchronously at EJB level do not using JMS and MDB? J2EE specification prohibits to use threads inside EJB so the only way I see is to create different thread on servlet side and invoke EJB methods from it. But it seems that this doesn't work too. Could anyone help me?
Thanks in advance,

If the passcode will not work, the only alternative is to restore the phone as new. You cannot change the passcode from the lock screen.

Invoke beanshell methods from java

Hello
I'm learning beanshell and using it to write scripts that are ran in JDK 6.
My question is how to invok beanshell methods from java source codes.
My codes is:
import javax.script.*;
public class InvokeFunctions {
public static void main (String[] args)throws ScriptException, NoSuchMethodException
ScriptEngineManager sem = new ScriptEngineManager();
ScriptEngine bshEngine = sem.getEngineByName("beanshell");
String script = "public void sayHello()"+"{print (\"sayHello() is a method in bsh script\");}";
bshEngine.eval(script);
Invocable inbshEngine = (Invocable)bshEngine;
inbshEngine.invokeFunction("sayHello");
I defined a method "sayHello()" using beanshell, but i just can't invoke it in Java.
I got an error msg said:
Exception in thread "main" java.lang.IllegalAccessError: tried to access method bsh.NameSpace.getThis(Lbsh/Interpreter;)Lbsh/This; from class bsh.engine.BshScriptEngine
Any one has any idea about it?
Thanks

Look at the Javadoc documentation of IllegalAccessError. It says:
Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.
Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
Maybe recompiling all your sources (make sure you delete all existing *.class files) will help?
