AccessContolException in IE not in Netscape

Please help, I'm really stuck on this one,
I have an applet which connects back to the machine of it's origin.
I work fine from any box running Netscape which I've tried but
usually fails with IE...I say usually because I do run it successfully
from one IE box.
Also...On one box with both IE and Netscape it works with Netscape
but not IE.
The failure is throwing an AccessControlException.
Thanks,
Brad

One more clue, here's the message.
AccessControlException(java.net.SocketPermission 127.0.0.1:7778 connect,resolve)
This is the message. I'm running it in a LAN right now and the
server is 192.168.1.170. Somehow I gues IE is tricked by the
server to think it's trying to connect to localhost 127.0.0.1...itself???
I don't understand.
Does anyone have a clue how I can fix this? The server is a Linux
box.
Please help,
Thanks

JSObject.eval() works in IE, not in Netscape 6

I've heard of the string you pass to eval() being too long so it takes a few seconds, but it doesn't work at all for me. And no errors in plug-in console.
I am trying to manipulate form values and then force a submit. That should be possible in Netscape 6 right? It works fine in IE.
Using jdk1.3 plug-in 1.3

Hi,
The plugin doesn't allow scripting of applets for Netscape.
From http://java.sun.com/products/plugin/1.3/basics.faq.html :
Q: Does Java Plug-in Software support scripting?
A: Java Plug-in Software supports scripting of applets in Internet Explorer. However, such scripting is not available when using Java Plug-in Software in Navigator. Because of limitations in Netscape's plug-in API, scripting cannot be supported directly (through LiveConnect) in Navigator. We are working closely with Netscape to address this issue in a future release of Navigator.

My applet shows in IE but not in Netscape

i coded an applet. It runs well in Internet Explorer on Windows but it cannot be shown in Netscape on Linux. I have set "enable Java" but the problem remains. The error information is "Applet myapplet error: java.lang.NoClassDefFoundError:myapplet".
The following is my html file:
<HTML><HEAD><TITLE>my applet</TITLE></HEAD>
<BODY bgcolor=WHITE>
<APPLET code=myapplet.class name=myapplet style="FONT-FAMILY:sans-serif; HEIGHT:800px; WIDTH:1000px ">
</APPLET>
</BODY></HTML>
Could anybody help? Thanks!
p.s. I used HtmlConverter to convert the above file and tried again. This time neither works!

I can think of at least three possible explanations for why your applet wouldn't work in Netscape:
1) Your applet tag specified the WIDTH and HEIGHT in a CSS style tag that Netscape doesn't recognize -- try to put the WIDTH and HEIGHT outside of style like this:
<HTML><HEAD><TITLE>my applet</TITLE></HEAD>
<BODY bgcolor=WHITE>
<APPLET code=PanelTest.class WIDTH=1000 HEIGHT=800 name=myapplet style="FONT-FAMILY:sans-serif; HEIGHT:800px; WIDTH:1000px ">
</APPLET>
</BODY></HTML>
2) Your applet doesn't require a Java plugin, take a look at Edit-->Preferences-->Advanced and make sure that you didn't inadvertently enabled Java Plugin in the preferences.
3) Your applet program was compile with j2sdk1.4.0 and you are trying to show it on a system that has different JRE -- if this is the case, the only way to fix the problem is not with the HTMLConverter but with a manual installation of JRE1.4.0 on Linux.
Hope this helps...

Ftp access works with Safari but not with Netscape or Explorer

The problem I am trying to solve is that my ftp service works correctly with Safari but gives an error message when the ftp service is access via Netscape or Explorer. Error message is "530 Guest login disabled". These two web browsers will not display a login screen for access by real users; Safari provides the login screen. The server is restricted to real users only

Check the proxy settings of the programs that are not working.
Check your firewall settings as well but I do not think that is it.

Applet work in IE but not in Netscape 4.01

Hi,
My applet work fine in IE. However, when it runs in Netscape 4.01, a securityException is caught. What should I do?
Best regards
From Hoifo

What should I do?Give us the stack trace and VM versions. You aren't using the plugin?
scenario: NN's VM is missing a class that IE's VM has. NN's classloader tries then to find it from the server but it can't of course find it, possibly resulting in a SecurityException. (A ClassNotFound should be more probable in that case, though)

OK in netscape, but not in IE

I created an applet that will run fine on netscape6.2. I try to run the same applet on internet explorer5.0 and I get the following message in my java console:
java.lang.NullPointerException
at DApplet.start(DApplet.java:81)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
I have the java 1.4 plugin installed on both netscape and internet explorer. Can anyone please help?

If is not a netscape vs IE problem, than why would it work fine in the netscape browser? Below is the start code that is given the exception...please see if you can help.
this is my start code:
/**Stop the applet*/
public void stop() {
System.gc();
System.out.println("DApplet: stoped");
Thanks!

I checked the Proxy settings in the java plugin console, and it says "use browser settings" . I also checked the settings in the browser in "LAN settings" but there is nothing checked (there is no ip address of any proxy server), does that mean we don't use a proxy server? and I should keep on looking for another cause to the problem?
Thanks in advance

Getting Mail.app to work as default from Netscape.

I've searched several forums and sites trying to find an answer and so far no luck so If anyone knows how to help Me I'll be extremely thankful.
I have Netscape 7.2, Safari 2.03, Firefox 1.01 and whatever version of I.E last came out for the Mac installed on my system. Of the first three (I never use I.E) both Safari and Firefox open the Mail.app when I click on a e-mail link in a web page. Despite everything I've tried I can not get Netscape to do the same. It always opens Netscape's mail program instead.
What do I have to do to get Netscape to use the Mail.app for in page email links?

This seems a little paradoxical... if it's hi-pri, why would you defer it for three days? but I guess it's your workflow
The issue here is what is your trigger? are you hoping to automatically identify hi-pri emails and you want your script to set them aside? or are you manually setting them aside and you want something to move them back?
In other words, i think you need to better explain your hopes/expectations here before anyone can tell you how (or if) AppleScript will fit in.

SetHeader("Content-disposition ) does not work in NN

response.setHeader("Content-disposition", "attachment; filename="+ fileName + strExt);
works for IE 5.5 but not in netscape .
IE 5.5 shows the save as dialog box
NN4.79 display the contents
how can i get the save as dialog box in NN4.79

try adding response.setContentType("your_content_type...") just before calling response.setHeader("Content-disposition", ...).
It seems that netscape requires it.

Netscape.javascript.JSObject for mac

I have the latest NetBeans version for mac os 10.5.
What do I need to do to get access to the netscape.javascript package.
I am trying to read cookies written using php into an applet. I am also open to solutions that do not need netscape.javascript.
I am a beginner to the mac os so I am unable to translate the many solutions that appear to be for windows users. Apparently all I need to do is add Plugins.jar to my classpath, but I cannot find Plugins.jar, (or java40.jar or JAWS.JAR which apparently contained these packages in various releases), none of which I can find on my mac or available for download.
I am sure this is very simple but I am running out of hair to pull out.

I believe that for Mac, the required jar can be called plugin.jar or netscape.jar.
Its location is somewhere around */System/Library/Frameworks/JavaVM.framework/Versions/<your version>/Home/lib*
I don't have a Mac so I can't verify this , sorry.
Good luck.

JRE and Netscape???

Hi there
I am having quite a problem with a java chat not working with Netscape and it doesn't matter what version I try.
I am not the developer of this chat, I just design and hire out for the backend work. My programmers are telling me that this is a Netscape problem and not theirs .. I spoke with Netscape today for over an hour and they say it is not a Netscape problem but the chat programming.
Since I am not a technical person I don't know who to listen to!!
I am not even sure what info to provide you with here so that someone can give some advice .. but can get whatever answers are needed.
You can see this chat in operation at www.personalstoday.com and you can log in as user test pass 4220 into any neighbourhood.
The applet starts and works fine with IE but with Netscape it just continuously asks for the plug in and never seems to find it.
Any help would sure be appreciated!!
Have a great night
Wen

Hi,
You can see this chat in operation at
www.personalstoday.com and you can log in as user test
pass 4220 into any neighbourhood.
The applet starts and works fine with IE but with
Netscape it just continuously asks for the plug in and
never seems to find it.I tried logging into your chat using Mozilla 1.2 which is
about the same as Netscape 7. I am able to reproduce your
problem to this extent: Your page prompts me to install the
1.3 plug-in, even though I already have it installed. I
cannot get your applet to load.
I suspect that there is an error in the Javascript that
supports the plug-in. For Netscape, you should ultimately
use EMBED tags. I am not sure which set of EMBED tags
actually gets enforced in my situation. I did notice that
in one case you have
<EMBED type="application/x-java-applet;version=1.1" ...
Maybe it should be "1.3"?
Your Javascript is very complicated and I don't know how to
interpret it. The debugging approach would be to create a
set of simple versions targeted to each situation that the
Javascript is trying to distinguish. That might help isolate
which block of code is broken or is not being invoked in
the right circumstance.
I have an applet based on the 1.3 plug-in which works fine on
my system. Maybe you could see what I am doing differently?
http://www.thecia.net/users/hamilton/minemaster/
(The applet is the button "Play Minemaster" in the upper left
corner; pushing it should pop up a frame. The appearance of
the button is enough to know that the applet loaded.)
That's all I have to suggest.
Good luck!

Netscape 6.01A

Hi
I installed Nerscape 6.01
on my Solaris-8 Intel system.
(Removed the previous one)
Updated the PATH.
When I click on the browser icon on the Front Panel
the Netscape is not being fired up.
And when I issue the #netscape
the error message says
" C locale package not found"
" /usr/bin/.netscape.bin not found"
Could any one help me
Thanks in advance.

Hello,
If you look at the release notes of Netscape they mention that Netscape 6.x will not run Java codes unless there 1.3.0_01 and above
Sometime you wonder where they get these ideas, that means that if you have an old applet it won't run with the new browser. I guess they never heard about backward compatibility

Disabling buttons in Netscape

I have a problem in disabling the buttons in netscape 6.2. It works fine in IE but not in netscape.
Scenario: I have two buttons. One is the Agree button and the other is the Disagree button. The Agree button redirects the page to another page while the Disagree button just closes the window. I also want to disable both buttons when I pressed the I Agree button. Here are the code that I used in disabling the button.
<input type="button" name="agree" onClick="this.disable=true;cancel.disable=true;nextwin()">
<input type="button" name="cancel" onClick="window.parent.close()">
Note: I also tried using javascript in disabling the button in netscape 6.2 but to no avail
I don't know if this is the right forum for my question but I hope that you could help... thanks

Excuse me but I have to disappoint you. Netscape doesn't do this. The best thing you can do is to disallow the focus with a javascript. Something like this:<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Disable...</title>
<script>
    function disable(elem) {
      self.status='Disabling ' + elem.value;
      elem.onfocus=dis;
      elem.onclick=dis;
      elem.enabled=false;
    function enable(elem) {
      self.status='Enabling ' + elem.value;
      elem.onfocus=null;
      elem.onclick=null;
      elem.enabled=true;
    function toggle(elem) {
      if (elem.enabled==null) elem.enabled=true;
      if (elem.enabled) disable(elem); else enable(elem);
    function dis() {
      document.forms[0].elements[1].focus();
      return false;
</script>
</head>
<body>
<form>
<input type="submit" name="submit" value="SUBMIT"/>
<input type="checkbox" name="enable" checked
     onClick="toggle(document.forms[0].elements[0]); return true;">enable</input>
</form>
</body>
</html>Ugly, but works. If your button is a picture you can switch between the enabled/disabled picture in the toggle() function. You cannot change the background or the text color of a button in Netscape.
Hope it helps,
Anton

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 :
