Winows xp x64 JRE 6u1 - no applets in Mozilla browser

Hi,
i tried to find similar posts but didnt find any. Im using Windows XP (pro) SP2 x64 on a AMD64 processor, and im having problems running applets in my browser (Mozilla 2.0.0.4). I've downloaded the newest JRE 6u1 available on the homepage, and also tried to download applet "plugins" thru Mozilla, but everytime i open a site with a java applet i get this error:
java.lang.NullPointerException

Since im not familiar to Java compailing and programming i dont know what this means.
Im thankfull for any suggestion fixin this error.

I think this is because of sandbox for web applications - see http://download.oracle.com/javafx/2.0/deployment/deploy_overview.htm#CEGJGHDA to understand the restrictions.
You need to sign your application and make sure JNLP requests all permissions.
Good news it is easy in Netbeans - just open project properties and select that application need elevated permissions.
Bad news is that official beta of 7.0.1 used experimental signing support that had bug for jars loaded from file protocol.
You may want to download latest NB 7.0.1 build (and recreate your project) or customize build.xml to sing jar file explicitly using standard ant signjar task.
Or you can always run your tests using http protocol to access the application.

Could not load applet in a browser using jre 1.6.0_06

Hi,
I am facing problem with loading applets when the browser uses jre 1.6.0_06.
Not able to understand what actually the problem is, I tried to check with a small applet that would simply print Hello World on the java console. Even this applet also could not be loaded on the browser. I could load this applet in the test environment of eclipse, but not able to load it on the browser when the applet is deployed on Tomcat.
We have no problems in loading applet if the browser is using an earlier version of the jre.
One more thing we have found out that, if we change the SSL cipher suite of the ssl.conf file such that it can support weaker protocols, my applet works with jre 1.6.0_06 also.
But one thing we could not understand is that why changes in SSL cipher suite of the ssl.conf file creates problem in loading the applet, only in case the browser is using jre 1.6.0_06. I mean to say that changes in the SSL cipher suite does not create any problem in loading the applet if my browser is using an earlier version of jre 1.6.0_06.
Please help me out as I don't have any clue regarding this problem.
Thanks in advance.

Hi,
We have found a wor around for this problem.
The following option has been unchecked and the applet could be loaded.
Go to java control panel
Under the Advanced Tab
Under the Security section
Uncheck the last option "Use TLSv1.0".
This makes the applet work.
But could not understand as why this is creating a problem.
We have tried to include TLSv1.0 in the cipher suite of our apache server, while keeping the above option in java plugin control panel checked, but even that did not solve the problem.
Please help me of how should I proceed for this problem, as I am totally stuck.
Thank you.

In Applets, unable to type in TextFields if JRE 1.4 is selected in browser

In Applets, unable to type in TextFields if JRE 1.4 is selected in browser (IE and Netscape), mouse events are functioning normally.
I was able to select CheckBoxes, set the focus from one TF to another TF, but unable to type into it.
Java Console shows: Java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThread)
It works fine if JRE 1.3 or MS VM is selected.
p.s. Applet code is compiled using jsdk 1.3
I will appreciate any kind of help or advice !
Thx,

Hi,
I have the same problem.
Would appreciate some help here also.
thanks!

X64 JRE does not support Chinese?

I have application that runs in multi-languages. I have pre-defined list of languages to be supported and I add the language to the combobox if it is installed in the machine where the application is running.
I used Locale.getAvailableLocales() to check for installed languages. In x64 machines with JRE 1.5 or 1.6 installed this call does not return East Asian languages such as Chinese and Japanese eventhough it is installed. Even in Chinese OS the call to Locale.getAvailableLocales() does not return chinese. I made several tests and it looks like the x64 JRE of 1.5 and 1.6 has this problem. I tried the 1.4 JRE and installed it in x64 machine and it was able to detect that Chinese is installed.
I tried setting the default languange to Chinese-China through Control Panel but Locale.getAvailableLocales() still does not return chinese. Although, all other programs are already in chinese. On the other hand, Locale.getDefault returns zh_CN which is correct. I don't understand how Locale.getDefault could return zh_CN while Locale.getAvailableLocales() did not include Chinese in the list.
I also tried SimpleDateFormat.getAvailableLocales() and DateFormat.getAvailableLocales() but they return the same list as Locale.getAvailableLocales.
Does anyone know of other ways of checking for installed languages that would work in x64 machines running 1.5 or 1.6 JRE?

Hi,
I know nothing of x64 JRE's, but when running into a similar problem I eventually found that I installed the (Sun) JRE with the default options. I needed to re-install the JRE and then clicked "Advanced options" (or something similar) on the first installation screen. Then you have an option to select all fonts, including Asianfonts). After I installed with all possible options my problems were gone.
I'm not at all sure that this is causing your problem but you might try,

please provide any pointers to resolve it.
TIA

Did you try a full trace to see why the jre can't connect with the server to get the applet?
To turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log

JRE for Linux ARM architecture plus browser plugin

Thank you for help

Hi There
Are you using Mozilla Firefox to access the console or Internet explorer ?
If its INternet explorer then please follow this :- +
Installing TightVNC for Non-Linux Users
After Oracle VM Manager is installed, install the TightVNC-Java applet for non-Linux users to access virtual machines. Download the latest version from: http://oss.oracle.com/oraclevm/manager/RPMS/.
To set up the TightVNC-Java applet:
Install it using the command:
# rpm -ivh tightvnc-java-version.noarch.rpm
version refers to the version of the TightVNC-Java applet. For example:
# rpm -ivh tightvnc-java-1.3.9-3.noarch.rpm
This should work out for you, try it in INternet explorer first, then you will know if it worked.
Make sure u restart after installation of the RPM
cheers
let moi know how u get on

Problem in loading applet in HotJava browser

I am having a problem in loading a simple applet in HotJava
browser
The code of the applet is shown below
import java.awt.*;
import java.applet.*;
public class HelloJava extends Applet
public void paint(Graphics g)
g.drawString("Hello Java", 10, 100);
The code of the HTML file HelloJava.html is shown below :
<HTML>
<! This page includes a welcome title in the title bar and also
displays a welcome message. Then it specifies the applet to
be loaded and executed.
>
<HEAD>
<TITLE>
Welcome to Java Applets
</TITLE>
</HEAD>
<BODY>
<CENTER>
<H1> Welcome to the World of Applets </H1>
</CENTER>
<BR>
<CENTER>
<APPLET
CODE = HelloJava.class
WIDTH = 400
HEIGHT = 200 >
</APPLET>
</CENTER>
</BODY>
</HTML>
ON opening the HTML file in HotJava Browser, the following error comes up :
HelloJava: class not loaded: file:/D:/Poonam/Java/Src1/HelloJava.class:
java.lang.ClassNotFoundException: HelloJava: class not loaded: file:/D:/Poonam/Java/Src1/HelloJava.class

Well the obvious question is what is utilities.PropertyManager up to at line 23? It appears to be trying to get the system classloader which applets aren't allowed to do.
You should probably be using the ClassLoader from the class in question.

Problem viewing applet in a browser

Hi guys,
i'm facing a basic problem in viewing an applet in a browser say
IE or netscape. beside adding the applet tag to the html file that i want to browse ;is there any other operation to perform on browsers or the Applet in order to view it ?
i would be very grateful if you help me fix this!
thanks indeed
othman

- Is there a plugin installed on the client machine
- Is the browser java enabled
- What tags are you using .. show your html code
- Are you aware of the security restrictions of the applet and its sandbox
- Are you able to view the console. What exceptions do you see if any.. show your exceptions
- What version of IE or Netscape are you testing with
- What OS are you using, what jvm version..
- Is the plugin set to be used with IE and Netscape in the Plugin control panel
- Is your applet code in the same directory as your html file. Does your codebase attribute reflect this.

Launching same applet in new browser window

Hi,
I launched applet in netscape browser and it worked fine. Then I opened a new window and pointed same url as first browser, applet main window is launched but because of shared static variables the two applets conflict each other.
we understood that applet from same code base loads in to same name space so the static information is shared between different applet instances.
one solution might be creating our own ClassLoader- browsers SecurityManager dont allow outside application to create ClassLoader unless user sets security policy to allow.(I cant ask user to do that and I cant afford signed applet solution)
basically I am looking for a solution like
1. launching new instance of netscape which dont share its JVM with other netscape windows(I dont know how to make it)
2. triggering netscape to use different class loaders(its own classloader) every time.(How??)
3. heard mayscript html flag helps(I have no idea)
4. any better solution
Your help is very importent so any suggestion or solution is welcome
thanks in advance
rana pratap nama

the most simple idea is to avoid the usage of static variable when the values of theese variables will be private to each applet instance...
much more simple than create a new class loader...
remember: a static variable should be used only when you want the same value shared by all instances of a class... otherwise use the private ones...

Run applet on wireless browser

A liitle help please :)
I do lots of java apps but this is my first foray into the wild and woolly wireless world. . .
I have a web app the runs an applet in the browser. I need some help in figuring out how to enable this applet to run on a browser for a wireless device.
Thanks!

Applet needs Java SE runtime Env.
Most device in wireless world don't support j2se but also java ME.
In order to run an applet on a browser for a wireless device you must find a device that support java SE.

Inited applet closes the browser automatically

Hello everybody!
I�m new with java and have a strange problem excuting my applet with Mozilla and Internet Explorer but not with Mozilla Firefox.
I have been reading the forum but haven�t found any similar problem.
When I run my applet with Mozilla or Internet Explorer, it says 'Miniapplet inited' in the status bar and suddendly closes the browser window. However if I run the same applet with Mozilla FireFox it goes perfect.
Any idea?
Thanks in advance!!

Don�t know what happened but now it is saying the java.io.IOException: CreateProcess: ... error=2.
As I have been reading it means there's no file. If I write down the complete path it goes fine. However, I would like to run an executable file which is in the browser but wanna be executed by the client, is it possible with getRuntime.exec()??
Thanks!!

How to run a Applet in a browser. No one REPLIED. Plz help

I had created a applet.

my applet is not running.
In the browser's bottom status bar , it says "notinited".
I dont know what is the mistake.
Please tell me what I should do. I am pasting my html file here.
<HTML><applet code="MortgagecalculationApplet.class" width=421 height=481></applet>
</HTML>

Hi..
Well I tried doing somthing which worked.. would like to share with you...
actually in the jar file created , if the class file is kept in the root directory of the jar file... it works...
eg. while crating the jar, if we go to the directory of the class file and then create it , it ould work..
if u r in som other directory while creating the jar, it wont work..
for the jar created, open it with winzip and if in the path column of the required class file if it shows a path, then it wont work..
else it will..
dats wat I ve found out....
