Applets and Netscape 6!

Hi there,
I am not sure if this is the right forum to post my question. However, i saw some discussions reg. Applets on Netscape 6 and i guess that many of you might be familiar with the scenario.
I'm having trouble getting any applets to work on Netscape 6 when I have HTTP authentication on the webserver enabled. The applet works fine under normal circumstances.
Instead of loading the applet, I get a Java dialog box saying "Enter Network Password" and asks me to enter my username/password. This is a specific Java dialog box, complete with a picture of Duke, and it
gives my firewall, digest and realm information.
However, the dialog box doesn't accept my username/password, and doesn't
display my applet.
Here is what i captured on the Java console:

Thanks for your help.

oops, i forgot to add this, can u tell me what speeddial.class is trying to do?
i belive u r making a url connection in that class and u got a null exception.
if u r indeed making a urlconnection, be sure to include the basic authentication in the headers. here is a sample
String basicAuth = Base64Coder.base64Encode("username:password");
basicAuth = "Basic " + basicAuth;
java.net.URL url = new java.net.URL(strUrl);
java.net.HttpURLConnection con = (java.net.HttpURLConnection) url.openConnection();
con.setRequestProperty("Authorization", basicAuth);

Dear Experts.
Reading through previous Forum similar questions, I changed the code (down below)
Now I receive the message:
Click here to get the plugin
This is encouraging because before Netscape ignored the applet completely ...
However I already have plugin version 1.4.2_03 installed (and recognized by Explorer)
The question is still why the applet is not working with Netscape ?
Thank you in advance for your help?

Java Applet crashes Netscape upon Exit?

Hello, I created an Applet that I am opening in NEtscape. When I make an attempt to exit (i.e. destroy) the APplet, it crashes the whole netscape. It even happens within Netscape 7. Is there a way around this since it makes a big problem for me to use the applet if it is going to crash my Netscape browser. I`ll appreciate any suggestions or comments, thanks Ivan

The main class that everything is in is called GUI.java and it is a frame. In order to open this as an Applet in netscape, I created a GUI_RMIApplet.java file. And The GUI_RMIApplet.html file opens the GUI_RMIApplet.java file which in return opens GUI.java. The exit call is in GUI.java file.
The html file code is as follows:
<EMBED type="application/x-java-applet;version=1.3" CODE = "musr.client.gui.GUI
_RMIApplet.class" CODEBASE = "." ARCHIVE = "jar/musr.jar" NAME = "MUSR GUI APPLE
T" WIDTH = 400 HEIGHT = 300 ALIGN = middle VSPACE = 0 HSPACE = 0 UBBoption = "de
velop" scriptable=false pluginspage="http://java.sun.com/products/plugin/1.3/pl
ugin-install.html">
<NOEMBED>
The GUI_RMIApplet.java code is:
package musr.client.gui;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import javax.swing.*;
import java.rmi.Naming;
import java.rmi.RemoteException;
import musr.server.*;
public class GUI_RMIApplet extends Applet {
boolean isStandalone = false;
String message = "The application will launch in a separate window";
GUI_RMIServer obj = null;
/**Get a parameter value*/
public String getParameter(String key, String def) {
return isStandalone ? System.getProperty(key, def) :
(getParameter(key) != null ? getParameter(key) : def);
/**Construct the applet*/
public GUI_RMIApplet() {
/**Initialize the applet*/
public void init() {
try {
jbInit();
} catch (Exception e) {
System.out.println("GUI_RMI exception: " + e.getMessage());
e.printStackTrace();
/**Component initialization*/
private void jbInit() {
// Main bulk for this applet
GUI gui = new GUI();
gui.setVisible(true);
public void paint(Graphics g) {
g.drawString(message, 25, 50);
/**Get Applet information*/
public String getAppletInfo() {
return "Applet Information";
/**Get parameter info*/
public String[][] getParameterInfo() {
return null;
//static initializer for setting look & feel
static {
try {
//UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
//UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
catch(Exception e) {
And, the GUI.java class calls these funcitons when exit menu button is selected:
GUI.this.dispose(); // disposes the frame
System.exit(-1); // disposes the applet (?or not?)
I think the System.exit button is messing things up but I don't know what other function I can use to close teh applet.
Hope this is enough information.

Persistent applets in Netscape 7.x

When I run my applet in Netscape 4.x,navigating to a different page cause my applet to get a stop() call, then pressing the "Back" button the applet gets a start() and I can resume the work. All the sockets are still open. Using the same applet in Netscape 7.x, I get a destroy() call and all the sockets are shutdown. This makes it impossible for me to resume my session when pressing the "Back" button.
Is there a way to instruct the browser not to destroy the applet when the page is not visible?

Is destroy overrideable? If so, just return from it.It's too late. I just get some exceptions and my sockets are closed. I need to avoid calling destroy() at the first place.

Reloading an applet closes Netscape 7.0 browser

I'm loading an applet that loads an image web cam with JMF api. Everything works o.k. But after using the applet, if i go to another html page, loads it but the Netscape browser closes. I've looked at the Netscape java console and it gives me all these errors. Could anybody help me please, it's very urgent?
I don't know how to solve this problem. Here's the code of my applet.
import java.applet.*;
import java.awt.*;
import java.net.*;
import javax.media.*;
import java.awt.event.*;
import javax.swing.*;
public class AppletSound extends JApplet {
     MediaLocator mySound=null;

     String audio=null;
     public void init()
          audio=getParameter("audio");
          getContentPane().setLayout(null);
          setSize(300,50);
     // Check that we have a valid URL and create URL object to hold it.
          if(audio.equals(""))
               System.out.println("*Please specify one URL to play*");
          else
               mySound=new MediaLocator(audio);
try {
          soundPlayer=Manager.createRealizedPlayer(mySound);
          catch(javax.media.CannotRealizeException cre){}
          catch(javax.media.NoPlayerException npe){}
          catch (java.io.IOException e) {
System.out.println("IOException...exiting.");
//System.exit(1);
if (soundPlayer == null) {
System.out.println("soundPlayer is null...exiting.");
// System.exit(1);
          auControlComponent=soundPlayer.getControlPanelComponent();
          if (auControlComponent!=null)
          getContentPane().add(auControlComponent);
          auControlComponent.setBounds(5,5,295,40);
validate();
     public void start()
          if(soundPlayer!=null)
          soundPlayer.start();
public void stop()
soundPlayer.stop();
     soundPlayer.deallocate();
Here are the errors that I get from the Java Console:

Applet On Netscape and IE

We are building a shopping cart applet using jdk1.0.x
When the user clicks on a submit button applet makes a connection to the server and waits for the server response. This piece of code makes a status message visible while the applet is waiting for server response.
public boolean mouseDown(Event event,int x, int y)
if (y >= 235 && y <= 260 && x >= 433 && x<= 511 )
lMessage.setVisible(true);
parent.SubmitInfo();
parent.Confirmation(); // make next page visible
return true;
The message is visible in Netscape , but in IE (both in MAC and Windows) it does not show up.
Does anyone have any ideas ?
Thanks in advance
Syama.

Hi, Guess I should have given code sample. lMessage is a label and it is added to the panel.
It does not display on IE but it displays on Netscape.
public class Review extends Panel
// members
public Review(ECommerce _parent)
// add size other components
     add(lMessage);
     lMessage.reshape(10,240,300,20);
     lMessage.setFont(parent.mFB);
     lMessage.setBackground(parent.bC);
     lMessage.setForeground(parent.mtC);
     lMessage.setVisible(true);
// other methods none of them refer lMessage
public boolean mouseDown(Event event,int x, int y)
     if (parent.submitOrder) return true;
     if (y >= 235 && y <= 260 && x >= 433 && x<= 511 )
          parent.submitOrder = true;
                         lMessage.setVisible(true);
     lMessage.requestFocus();
     repaint();
     parent.SubmitInfo();
     parent.Confirmation();
     parent.submitOrder = false;
     return true;
May be it has something to do with jdk - we are using jdk 1.1.
Thanks,
Syama.

Creating signed Java applet for Netscape 4x

I have created a signed jar with SuperUser privileges under Netscape.
public void init() {
try {
if( Class.forName("netscape.security.PrivilegeManager") != null ) {
netscape.security.PrivilegeManager.enablePrivilege("SuperUser");
} catch( ClassNotFoundException cnfe ) {
cnfe.printStackTrace();
With this I am getting following error without any dailog prompting to grant permission.
netscape.security.ForbiddenTargetException: User didn't grant the SuperUser privilege.
Please help.
Thanks
Satish

Then it's likely Netscape 4.x doesn't recognize the jar as being signed. How did you sign the jar?
Why didn't you ask this in the more appropriate Signed Applets forum?

Java Applets in Netscape with EMBED tag

Hi,
I tried to run the examples on the:
http://192.9.48.9/products/plugin/1.3/demos/applets.html
Demo paged off of the plug page and in Netscape 4.08 it
does not know there is a plugin , in Netscape 6.0
it knows there is a plug in but won't use the one installed on the machine (1.3.1) which is the same level as the demo.
Any clues how to get applets to use the Java Plugin with Netscape? This works fine in IE
Thanks!
BTW- I'm using NT 4.0 os.

Probably 1.3.1 conflicts with 1.3.1_01 or 1.3.1_02.
You need the HTML Converter from the Java PlugIn download page to make your page ready for Netscape 4.x. Go to http://java.sun.com/products/plugin/1.3/converter.html (Java Plug-in HTML Converter Download) to download your copy of the HTML Converter. Watch for the current version, it is 1.3, not 1.1.1.
Download your page, strip out the <embed/> and <object/> elements, uncomment the <applet/> element and run the HTML Converter.
Additional Information:
Netscape 6 does not use the <embed/> element anymore since it isn't a html element but was a proprietary netscape tag. Netscape 6 uses the <object/> element like Internet Explorer and Opera.
Another note on <embed/>:
Use of <embed/> is strongly discouraged, but there's no other chance. Let's hope support for Netscape 4.x won't be neccessary any more in a few months.
A note on <applet/>:
The <applet/> element is deprecated since HTML 4.01 or earlier (http://www.w3.org/TR/html401/struct/objects.html Objects in HTML 4). One should use the <object> element instead anyway. The semantic description of html elements found in the technical report of the html 4.01 recommendation is still valid for current html versions of today (XHTML 1.1 and XHTML Basic 1.0).
There's also a funny page of Sun about HTML: http://java.sun.com/products/plugin/1.3/docs/tags.html. Don't take that page too serious since it states it is talking about HTML, but it isn't.
If you use the HTML Converter, be sure to use the Extended (Standard + All Browsers/Platforms) template to tell Netscape, Opera and Internet Explorer regardless of the used version to display the applet correctly. But watch out: the generated code is not HTML and will perhaps even crash your page in Internet Explorer 6 and browsers that rely on the HTML standard! It also won't work with Netscape 6 if there is a different version of the Java Plugin installed more recently than the requested. I have SDK 1.3, 1.3.1 and 1.4 installed, and Netscape 6 wants to download the 1.3.1 Plugin.
The best way to make your applet work in really every browser is to study what the converter is trying to do and code it by yourself in a conformant way. Be sure not to tell the browser the Plugin version to use to avoid the neccessarity of downloading outdated plugins and installing several plugins (1.2, 1.2.1, 1.2.2, 1.3, 1.3.1, 1.3.1_01, 1.3.1_02, 1.4...).

Scripting applet in netscape

I have Netscape 4.75 and I want to access methods of applet
which is compiled with jdk 1.4 and is using swing classes?
How is that possible?
I have installed java plug-in 1.4 but then the applet is not
scriptable with plug-in.

Try to add the parameter MAYSCRIPT="true" to the applet tag and convert your HTML file with the htmlconverter program that comes with the jdk. If that still doesn't work, upgrade to NN7.02 -- I know it works..... you can check it out at the link shown below:

Applet in Netscape (gah! due today)

Any ideas why an applet wouldn't align properly in Netscape? It works fine but it's not fitting in table correctly.
Thank you so much!!!!!!!!!!

Images and applets never align properly in Netscape because Netscape is a pile of cr*p (excuse my language). If it works in IE, you know you're doing it roughly right.

Repaint problems with an applet under Netscape 4.75

Hello,
I'm currently working on an applet created with VisualAge for Java, running under the standard Netscape 4.75 JVM, with Windows NT4.
I am experiencing problems with AWT components which randomly disappear, especially Labels and sometimes Panels. When I drag a window over the missing label and then drag it back, the label appears.
I have tried a lot of combinations with the repaint(), paint(), paintAll() and paintComponents() methods, but it has not been efficient for the moment. Introducing lots of repaint() calls on the concerned labels is even worse.
Is there a known bug in the Netscape 4.75 JVM concerning this problem ? Do you have an idea of what can be done to solve this problem ? Changing the JVM is not an option that can be chosen. Netscape 4.75 has been defined as the only browser for the whole project.
Thanks for your help !
Kevin

Well, I finally solved this problem.
For your information, the JVM included in Netscape 4.75 running under NT4 does not like having AWT labels with either Background or Foreground not initialised. If any of these 2 properties is not defined, it could sometimes occur that the JVM can't display the label.

Applet parameters & netscape

I've got an applet running, but it seems
that if I run it with Netscape, the applet
is not receiving the parameters properly.
I can get them just fine with Internet Explorer or with appletviewer.
I only get the default values that are coded
into the java applet.
For example:
I have a parameter called url_link, that
I use to switch to another URL.
In the applet code, it's defined as:
url_link = this.getParameter("url_link", "");
In the HTML page, in the part
else if (_ns == true) document.writeln('<EMBED type="application/x-java-appl
et;version=1.2" WIDTH = 350 HEIGHT = 200 ALIGN = middle NAME = "Login" java_CODE
= "Login.Login" java_ARCHIVE = "jdev-rt.zip,classes12.zip,OpamicLib.jar,Login.j
ar" java_CODEBASE = ".." "url_link" = "success.html" pluginspage="http://java.s
un.com/products/plugin/1.2/plugin-install.html"> <NOEMBED><XMP>');
The <APPLET> tag contains:
<PARAM NAME = "url_link"
VALUE = "success.html">
In netscape I just get an empty string for
this parameter value unless I hard code
something different in the Java code, but
it never gets replaced by the parameter
that's specified in the HTML page.
So what do I have to do to make this work
with Netscape?
null

Well nobody replied to this one, so I had
to figure it out myself.
The JDeveloper tool puts all the parameter
names in the <EMBED> clause in quotes.
If those are removed, then it works fine
in Netscape.
So, replace
else if (_ns == true) document.writeln('<EMBED type="application/x-java-appl
et;version=1.2" WIDTH = 350 HEIGHT = 200 ALIGN = middle NAME = "Login" java_CODE
= "Login.Login" java_ARCHIVE = "jdev-rt.zip,classes12.zip,OpamicLib.jar,Login.j
ar" java_CODEBASE = ".." "url_link" = "success.html" pluginspage="http://java.s
un.com/products/plugin/1.2/plugin-install.html"> <NOEMBED><XMP>');
with
else if (_ns == true) document.writeln('<EMBED type="application/x-java-appl

Signed Applet for Netscape 4x

I have created a signed jar with SuperUser privileges under Netscape.
public void init() {
try {
if( Class.forName("netscape.security.PrivilegeManager") != null ) {
netscape.security.PrivilegeManager.enablePrivilege("SuperUser");
} catch( ClassNotFoundException cnfe ) {
cnfe.printStackTrace();
With this I am getting following error without any dailog prompting to grant permission.
netscape.security.ForbiddenTargetException: User didn't grant the SuperUser privilege.
Please help.
Thanks
Satish

Hi,
this is exactly the same problem I am facing here. Each time I try to grant/enable a capability, it is automatically denied without any dialog. Do we forget something?
I only signed the applet with the netscape signtool, not with a real certificate from verisign or such, does that matter?
Please let me know if you found out how to do it.

=3 applets hanging Netscape with 1.3.1_01a or 1.3.1_02

The Java 2 v1.3.1_01a and 1.3.1_02 Plug-Ins completely hang Netscape 4.79 (and probably 4.x in general) and 6.2 when there are 3 or more simple applets in a single HTML page. This can be reproduced with a simple empty sub-class of java.applet.Applet and placing 3 or more instances of this in one HTML page (e.g. via jsp:plugin). [I used 16x16 applets in this case.]
Note that I could get 3 instances of an extremely heavy, slow-loading JApplet-based applet to load without hanging Netscape, so there appears to be a timing, deadlock issue here.
I have attempted to file a JDC bug on this matter, but it was not accepted as I could not reproduce the bug in Java 2 v1.4! Given that this issue spread to 1.3.1_02 (I originally found it in 1.3.1_01a), I am afraid it may leak into 1.4 at some later point, however!
Has anyone else experienced this?
Any workarounds?
[I use extremely lightweight applets in potentially large quantities (e.g. dozens) in HTML pages. 1.3.1_01a and 1.3.1_02 are thus complete non-starters in Netscape -- and I require 1.3.x functionalities in the applet. 1.3.1_01 works beautifully in Netscape and Internet Explorer for over 150 applets in one page -- though Netscape is substantially slower than Internet Explorer in this case. 1.3.1_01a and 1.3.1_02 work beautifully in Internet Explorer -- but hang Netscape completely in this case.]

I tried turning off Recycle ClassLoader.
I even tried turning off the "Default VM" stuff for Netscape (as that is new to 1.3.1_01a and higher, of course).
Neither made any significant difference. I sometimes got 3 applets to come up on a page without hanging, but visiting a couple such pages produced a nearly guaranteed hang.
I wonder if this is related to the spurious HTTP request the Plug-In makes in Netscape.
The Plug-In (1.3.1 and higher at least) appears to always makes 1 additional HTTP request in my experience when in Netscape as compared to Explorer. I never would have noticed this except that this request happens to hit a servlet which logs such things with a request with no path-info (and it requires path-info).
