Java Plug-In1.3.1_03 and downloading applets

hey,
Following is the detail of my problem with Java 1.3.1_03 Plug-In:
I have a java applet written using Microsoft SDK 4.0 in Java 1.1.
This applet is downloadable from the browser. When I have the Java Plug-In enabled to load applets (in my Browser - options - advanced) - the applet gets downloaded fine but, does not find the cab file that has been downloaded. If this Java Plug-In option is not ticked in my browser then, the applet works fine and the cab file could be found.
Help will be much appreciated. Thanks.

hello,
Actually, i think the Java Plug-In writes the path of the directories and the Java VM elsewhere in the registry and the browser is set to look it up in the usual Microsoft->JavaVM place in the registry. But, I cant seem to find the key that it puts the path in. If you have any leads, do fill me in. Thanks.

IE6 and java plug-in1.3.1_02

Hi,
using previous version of IE and Java plug-in I had the external java plug-in called if, and only if, I use the tag:
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" ...
Now, having IE6 and java plug-in 1.3.1_02 I get the browser call the external plug-in also when using the tag:
<APPLET ...
while normally the browser internal plug-in was called.
Is it a new specification of the plug-in or of the browser?(could not find any clue on MS web site)
TIA
Oscar

When the plug-in installs, it sets itself to be your default environment for Java in Internet Explorer (unless you uncheck that box). If you go to your Control Panel, the Java plug-in icon should appear, and you can right-click to Open it. On the Browser panel of the Java Plug-in Control Panel you can set which browsers you want, or don't want, the plug-in to be the default Java Virtual Machine for.

Unable to run Demos applet in java plug in 1.3.1_04

Hi
This is dipak here, I am try to run sample appplets program from java 1.3 samples and codes page of java.sun.com, but I am getting a security warning saying that "Do you want to install and run Java Plug-in1.3.1_13".
I already install J2RE , i.e. Java Plug-in 1.3.1_04.
Please tell me what i have to do and Java Plug-in 1.3.1_04 is still supported by java1.3 samples and codes or not.
Thanks in advance for help.
Thanks and Regards
Dipsy

Apparently the applet you're trying to run is wanting the more recent version of Java, and is asking you to install it.
The version you have (1.3.1_04) is very old and reached End-of-Life years ago. Updating to Java 5 would probably resolve the issue.

Issue with Internet Explorer and Java Plug-in

Hi, I have a problem here and I hope someone knows whats going on. I have installed the Java Plug-in 1.4.0_01 and I have no problems using the plugin from Netscape.
Now when i try to load the applets using IE, it will not use the Sun plug-in that is installed. I have selected both IE and Netscape in the Java Plug-in Control Panel and IE still does not want to use the plug-in.
Is their a way to force IE to use the plugin?
Thanks!!

Static variable, a bug in applet classloader, Java plug-in?

I found a potential bug in java plug-in.
Environment,
1. IE 6.0
2. Windows XP
3. JRE 1.3.1.06 and JRE 1.4.1.01
Steps,
1. build a very simple applet (attached below)
2. embed the applet into a .html page.
3. enable java plug-in for IE and Netscape.
4. launch the .html page in either of the two browsers.
5. for the 1st time, I can see 'tmp = 0' in the java console window.
6. keep the browser open, browse to 'www.google.com'
7. click 'Back' button of the browser.
8. I notice 'tmp = 1' in the java console window.
9. if I browse to google.com and back again, it will display 'tmp = 2'. and the number will keep on increasing if I repeat those steps.
10. But if I press F5 to refresh the page, the log message will go back to 'tmp = 0'. and if I press 'x' inthe console window to clean up the classloader cache, I will get 'tmp = 0'. If I close the browser and open a new one, I will still get 'tmp = 0', which is what the applet should output.
11. If I click 't' in the console window to list the thread while I am in the 'google' page, I can't see the applet thread, which means the applet should have been destroyed.
12. No matter I try 'g' to do garbage collect, or 'f' to finalize objects, the problem still happens. the only solution is what I did in the step 10.
Is it a bug in the classloader or the JRE itself? Why the value of the static variable won't be cleaned up along with the applet?
----------- HERE IS THE APPLET --------------------
import java.applet.Applet;
public class AA extends Applet
private static long tmp = 0;
public void init() {
System.out.println("tmp value = " + tmp);
tmp++;
public void start() {}
public void stop() {}
public void destroy() {}

Static values are stored in the class. Once a class is loaded into a classloader, it cannot be unloaded (the only thing you can do is use another classloader).
Apparently, the classloader cache allows sharing of classloaders between applet instances. Perhaps F5 (reload) causes the classloader cache to be cleared.
I don't see any bug. When developing applications or applets that must run in the same JVM, you should program defensively and avoid using static values which can change over time.

How do download Java Plug in

I dowloaded J2SE runtime environment 5.0 update 2. Where do I dind the Java Plug in?

You can download J2SE runtime 5.0 update 3 from the
java web site www.java.sun.com.No, that only has 1.5.0_02. To get the _03 update, go to java.sun.com and click J2SE 5.0 in the Popular Downloads box at the right.
This excerpt from Graham Hamilton's (Sun VP) blog explains the policy:
"We will not be releasing 5.0 Update 3 on java.com or via auto-update. Here's why.
Our goal is that the update releases be boring. Seriously! They are intended to deliver fixes that will be important to some customers, but they aren't normally a "must-have" item for typical Java end users. So we don't necessarily want to push them all out to our mass consumer audience.
Java.com and the java auto-update mechanism are primarily targeted at making it easy for home consumers to get the JRE. As part of that, we're trying to make sure that the latest version available via java.com is the same as the latest version available via auto-update. But this won't necessarily always be the same as the latest release that is available on java.sun.com.
We will occasionally use auto-update to propagate a new version out to the consumer audience, but we want to do that sparingly. In March we enabled auto-update from 1.4.X to 5.0 Update 2 and as a result millions of consumers chose to do an auto-update to Tiger. We're glad they did that, but we don't want to bother them with another auto-update again too quickly."

Loaading Java Plug-in

Hi everybody!!
I have an applet that invoque from an HTML file, but when I call the HTML file a message in the toolbar browser appears: " Loading plug-in", then another message appears : " 10% de 580 K 23:43 remainig ....." and in the browser main page a gray window appears with the label : 'loading java applet'. Finally the applet appears.
So, Could you please tell me in detail what is happening from the html file is called to the applet appears ?
Or please, tell me where to find this information....
Nancy Cris�stomo

Sounds like the applet requires the Java plug-in to run and the messages you see are the download of that plug-in. See http://java.sun.com/getjava/help.html for more info. The reason the plug-in is required is that the JVM that comes with the browser does not include all the classes that an applet can use. The choice is either to write applets based on a limited subset of Java that the browser JVM supports, or to require a one-time download of a plug-in (which takes time, as you found out).

Authentication issue about java plug-in

Hi all:
Since it is a urgent issue and I really need some help,I post the same problem again .Here is my problem description:
I have a website hosted on a Microsoft IIS web server,the web server name is win2003stdbase1.Because of some custom needs,the website must use Kerberos authentication. Other authentication method such as NTLM will fail.The website contains a jar file.
When a client use IE to visit a html page containning a java applet on that site, the java plug-in launches and a dialog box pop up.Here is the Details of the dialog box:
Title: Password Needed - Networking
Server: win2003stdbase1/192.168.0.43
Scheme: ntlm
Use name:
Password:
Domain:
Even I input the right user name and password,the dialog keeps poping ups.
Suspect that the java plug-in use ntlm and it case the authentiaction failure.Can we conifgure the java plug-in to use Kerberos authentication type?And how to do it?
If I did not explain the problem clearly enough,please let me know.
Also any other suggestion about the issue are welcome.

You should always use the latest Java version. Older versions have security vulnerabilities and should not be used. You do not need Java Console extension and they may also not work anyway.

I have two itunes accounts on my mac... Can I plug in my phone and get music upload to it from either one? How can I merge them so that my husband and I can share our music?

I recently plugged in his phone and downloaded all the music from his apple id, music he had purchased. I have a different apple id. Can he share it with me? Would I be able to get it on my phone? Also, with home sharing on my apple TV- Can I turn them both on and get the music form both accounts or do I have to use one at a time?

Put all of the music in one itunes library and sync the idevices to that library

Installed the Java patch for MAC yesterday and immediately could not get adobe reader to show pdf files...have troubleshot and can't seem to remedy ...ideas?

I have used the Firefox troubleshooting guides, no good. The Java patch is enabled and shows when I check applications. However when I run Firefox plugins it still shows the java plug in is outdated and need to be updated immediately.

OK, I went to the Firefox knowledge base article you cited and followed the directions with the exception that in the drop down menu I choose Adobe Reader for PDF files rather than the plug in default that apparently was set by the Java patch. Problem solved !!!!!!! Thank you so much for taking the time to get me back to the basic place I needed to be to correct this issue. YOU ROCK!!!!

Is there a way for Flex to detect whether the Java Plug-In is installed?

Hi All,
Need your help.
Is there a way for Flex to detect whether the Java Plug-In is
installed? This may be require a JavaScript External-Interface. Can
we get if the Java Plug-In is installed and if so, whether it is
JRE 1.6.X ?
Regards,
Amit

Not knowing what server your app will run on... but something
like that can be done relatively easy serverside with for instance
ImageMagick if you run PHP.
Otherwise, look into Bitmap programming.

Applets and memory not being released by Java Plug-in

Hi.
I am experiencing a strange memory-management behavior of the Java Plug-in with Java Applets. The Java Plug-in seems not to release memory allocated for non-static member variables of the applet-derived class upon destroy() of the applet itself.
I have built a simple "TestMemory" applet, which allocates a 55-megabytes byte array upon init(). The byte array is a non-static member of the applet-derived class. With the standard Java Plug In configuration (64 MB of max JVM heap space), this applet executes correctly the first time, but it throws an OutOfMemoryException when pressing the "Reload / Refresh" browser button or if pressing the "Back" and then the "Forward" browser buttons. In my opionion, this is not an expected behavior. When the applet is destroyed, the non-static byte array member should be automatically invalidated and recollected. Isn't it?
Here is the complete applet code:
// ===================================================
import java.awt.*;
import javax.swing.*;
public class TestMemory extends JApplet
private JLabel label = null;
private byte[] testArray = null;
// Construct the applet
public TestMemory()
// Initialize the applet
public void init()
    try
      // Initialize the applet's GUI
      guiInit();
      // Instantiate a 55 MB array
      // WARNING: with the standard Java Plug-in configuration (i.e., 64 MB of
      // max JVM heap space) the following line of code runs fine the FIRST time the
      // applet is executed. Then, if I press the "Back" button on the web browser,
      // then press "Forward", an OutOfMemoryException is thrown. The same result
      // is obtained by pressing the "Reload / Refresh" browser button.
      // NOTE: the OutOfMemoryException is not thrown if I add "testArray = null;"
      // to the destroy() applet method.
      testArray = new byte[55 * 1024 * 1024];
      // Do something on the array...
      for (int i = 0; i < testArray.length; i++)
        testArray[i] = 1;
      System.out.println("Test Array Initialized!");
    catch (Exception e)
      e.printStackTrace();
// Component initialization
private void guiInit() throws Exception
    setSize(new Dimension(400, 300));
    getContentPane().setLayout(new BorderLayout());
    label = new JLabel("Test Memory Applet");
    getContentPane().add(label, BorderLayout.CENTER);
// Start the applet
public void start()
    // Do nothing
// Stop the applet
public void stop()
    // Do nothing
// Destroy the applet
public void destroy()
    // If the line below is uncommented, the OutOfMemoryException is NOT thrown
    // testArray = null;
//Get Applet information
public String getAppletInfo()
    return "Test Memory Applet";
// ===================================================Everything works fine if I set the byte array to "null" upon destroy(), but does this mean that I have to manually set to null all applet's member variables upon destroy()? I believe this should not be a requirement for non-static members...
I am able to reproduce this problem on the following PC configurations:
* Windows XP, both JRE v1.6.0 and JRE v1.5.0_11, both with MSIE and with Firefox
* Linux (Sun Java Desktop), JRE v1.6.0, Mozilla browser
* Mac OS X v10.4, JRE v1.5.0_06, Safari browser
Your comments would be really appreciated.
Thank you in advance for your feedback.
Regards,
Marco.

Hi Marco,
my guess as to why JPI would keep references around, if it does keep them, is that it propably is an implementation side effect. A lot of things are cached in the name of performance and it is easy to leave things laying around in your cache. Maybe the page with the associated images/applets is kept in the browser cache untill the browser needs some memory and if the browser memory manager is not co-operating with the JPI/JVM memory manager the browser is not out of memory, thus not releasing its caches but the JVM may be out of memory. Thus the browser indirectly keeps the reference that it realy does not need. This reference could be inderect through some 'applet context' or what ever the browser uses to interact with JPI, don't realy know any of these details, just imaging what must/could be going on there. Browser are amazingly complicated beast.
This behaviour that you are observing, weather the origin is something like I speculated or not, is not nice but I would not expect it to be fixed even if you filed a bug report. I guess we are left with relleasing all significatn memory structures in destroy. A simple way to code this is not to store anything in the member fields of the applet but in a separate class; then one has to do is to null that one reference from the applet to that class in the destroy method and everything will be relased when necessary. This way it is not easy to forget to release things.
Hey, here is a simple, imaginary, way in which the browser could cause this problem:
The browser, of course needs a reference to the applet, call it m_Applet here. Presume the following helper function:
Applet instantiateAndInit(Class appletClass) {
Applet applet=appletClass.newInstance();
applet.init();
return applet;
When the browser sees the applet tag it instantiates and inits the new applet as follows:
m_Applet=instantiateAndInit(appletClass);
As you can readily see, the second time the instantiation occurs, the m_Applet holds the reference to the old applet until after the new instance is created and initlized. This would not cause a memory leak but would require that twice the memory needed by the applet would be required to prevent OutOfMemory.I guess it is not fair to call this sort of thing a bug but it is questionable design.In real life this is propably not this blatant, but could happen You could try, if you like, by allocating less than 32 Megs in your init. If you then do not run out of memory it is an indication that there are at most two instances of your applet around and thus it could well be someting like I've speculated here.

How to set up a Java Plug-in Download page in case of netscape?

hai all of you,
i have a problem regarding downloading plugin.
i am using <object > and <embed> tags to download the plugins inorder to run the applets. but it is taking long time to download the plugin form sun.com.
so what i have done is, i downloaded the plugin.exe file and .cab file and put it in my tomcat server mainted by other party.(y application if for internet purpose only.)
i refered to http://java.sun.com/products/plugin/1.2/docs/intranet.html. there it is mentioned that, to download the plugin.
for I.E i can able to change the code.
but for NetScape it's a little bit confusing.
i have downloaded the binary file in my own directory.
here he is asking to set up a java plugin-in download page.
instead of this "plugin-install.html" page what page i should create and what should be the code in this page if i have to write on my own. please let me know if anybody know about it.
following para is from sun.com
"To deploy Java Plug-in in intranet environments with Navigator, you need to download and store the Java Plug-in binary file on one of your web servers. Then you need to set up a Java Plug-in Download page and modify the pluginspage attribute in the EMBED tag to refer to this page. The Download page should have options to download different versions of Java Plug-in, such as for Windows and Solaris. For example, if you have set up the Java Plug-in Download page at "http://javaweb.eng/plugin/" and the page is called plugin-install.html, you can specify the pluginspage as "http://javaweb.eng/plugin/plugin-install.html". "
thanks
by
sambareddy

I have successfuly done this.
Change the converted html as per the instructions to point to another page.
Here is an example of the new html page you need to create:
<html>
<head>
<title>Java Plugin Install Page</title>
</head>
<body>
<h2><center>Java Plugin Install Page</center></h2>
<p></p>
<h3>Windows Version Only!!!</h3>
Click here to Download Plugin
<p></p>
<p>You may or may not be asked to either save or run from current location</p>
<p>If the run from current location is available, use that option</p>
<p>If you can only save the file, then save it to your workstation and exit the download page and exit Netscape. Then using Windows Explorer, go to where you downloaded the file and double click on the file to run it. Accept all options during the install process and once it has finished try accessing your web page again using Netscape. You should then get to the web page or application and this page will not apppear again.
</body>
</html>
If you put the file j2re-1_3_1-win.exe on a web server somewhere then you will have to prefix the file with
http://yourwebserverdirectory/
Hope this helps.

JRE 1.7 / Java Plug-in - Long delay in retrieving the applet File(JAR) due to a request to the Domain Controller(on port 53)

Description:
A specific group of users/customers (using Windows7 OS with IE and FireFox web browsers) are facing problems with retrieving the applet File, after they upgraded the JRE on the system(PC) to JRE 1.7.0_25-b17 from JRE version 1.6.0_29-b11.
With JRE 1.7.0_25-b17 it is noticed that when the Java plugin requests for the applet File; it sends a request to the Domain Controller of the user, which causes a delay of 2 to 5 minutes and sometimes hangs. The problem occurs consistently.
The current temporary workaround for this group of users is to use JRE version 1.6.0_29-b11.
Problem analysis:
To investigate the problem the below steps were executed:
1) Collected the Java console outputbelow details from the user's system. (The complete output is not posted due to lengthy content, though can be added further to this post if required.)
(a) Works fine with JRE version 1.6.0_29-b11. Kindly refer to Java console output in the code ‘section A’ towards the end of this post.
(b) The problem occurs with problem with JRE version 1.7.0_25-b17. Kindly refer to Java console output in the code ‘section B’ towards the end of this post. The step where the problem is observed, is indicated as(##<comment>##).
2) The network settings in the user's browser was checked. Internet Options > Connections > LAN setting
The configured option is 'Use automatic configuration script' and the value is http://www.userAppX.com/proxy.pac
This configuration remains the same irrespective of the JRE version in use.
3) The network settings in the Java Control Panel was checked.
The used/selected option is "Use browser settings", although values for 'Use proxy server' and 'use automatic proxy configuration script' are filled-in as 'user-proxy.com' and 'http://www.userAppX.com/proxy.pac' respectively.
This configuration remains the same irrespective of the JRE version in use.
4) The proxy PAC file was checked and debugging was done for the request 'https://myAppletHost.com/download/...'. The FindProxyForUrl function (including the conditions defined in it, for the hostname and domain checks) returns PROXY user-proxy.com:80
5) The user also tried the below
a. Changed the option in the network settings in the browser to 'Proxy server' with Address 'user-proxy.com' and Port '80'
b. Restarted the browser.
c. Tried with Java Plug-in 1.6.0_29, JRE version 1.6.0_29-b11. There was no problem and no request to the Domain Controller of the user.
d. Tried with Java Plug-in 10.40.2.43, JRE version 1.7.0_40-b43. The problem occurs with the delay and a request to the Domain Controller of the user is observed.
Kindly refer to Java console output in the code ‘section C’ towards the end of this post.
6) The user also tried setting the below property in the Java Control panel; restarted the browser, and try with JRE 1.7.0_40-b43. The problem stil persists.
-Djava.net.preferIPv4Stack=true
7) The Global Policy Management of the Domain Controller was verified by the user. It has GPO for proxy setting but nothing related to Java security.
Questions:
The problem seems be specific to a particular (user) environment setup, and the user faces the problem when using JRE 1.7.
We would like to know if the issue is in the (user) environment setup or in JRE 1.7.
Could you please help with information/ideas/suggestions to identify the root cause and solution for this problem?

PS:
Since the JRE 1.7.0_25-b17 update, it is noticed that when the Java plugin requests for the applet File; it sends a request to the Domain Controller of the user, which causes a delay of 2 to 5 minutes and sometimes hangs.
The problem occurs consistently, and also with JRE 1.7.0_45-b18.

My organization is experiencing very similar problems. We have resolved it through several steps.
We upgraded the client to Java 8 and we saw in the console that the hanging connection with the Domain Controller no longer occurs. This may be all that is necessary for your environment as well.
