JDK Applet to IE version

what version of the JDK do I have to write my applets in to make them compatable with most "stock" installs of IE?

please help, this is killing me. some one told me that I was limited to 1.12
is that right?

Hello,
In Firefox 23, as part of an effort to simplify the Firefox options set and protect users from unintentially damaging their Firefox, the option to disable JavaScript was removed from the Firefox Options window.
However, the option to disable JavaScript was not removed from Firefox entirely. You can still access it from about:config or by installing an add-on.
'''about:config'''
# In the address bar, type "about:config" (with no quotes), and press Enter.
# Click "I'll be careful, I promise"
# In the search bar, search for "javascript.enabled" (with no quotes).
# Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now disabled.
To Re-enable JavaScript, repeat these steps.
'''Add-ons'''
You can alternatively install an add-on that lets you disable JavaScript, such as
*[https://addons.mozilla.org/firefox/addon/noscript/ No-Script] (to disable JavaScript on a per page basis, as required)
*[https://addons.mozilla.org/firefox/addon/quickjava/ QuickJava] (to easily disable and enable JavaScript, automatic loading of images, and other content)
Thank you and I hope this helps!

JDK 1.6+ 32bit version on Vista 64 - SYSTEM account issue

Hello,
I am just fishing for experience here with installing the Java JDK 1.6 (32 bit version) on Vista64 using the SYSTEM account. My test case that I am using is I can download any of the 1.6 JDK exe versions then create a simple task to run as SYSTEM that will execute the exe with the /passive (tried /qn as well) option this fails with "return code 1619" which is something about package can not be opened. However when the task is changed to run with an admin account this task completes return code 0 and the the JDK is installed.
The root problem here is we are attempting to install apps that require the 32 bit version of the JDK to be present to install where everything is being installed through SMS using the SYSTEM account.
Any insight anyone might have on this would awesome

Applets 'n win versions??

...ok, i created an applet (i copied out of a book, because i'm learning) and i tested it on my computer by creating an HTML file and using the <applet> tag with WinME. It didn't work, so i figured it was a problem with me not having the Java Runtime Environment, so i downloaded that and it still did not work. Being used to errors on diff. op sys. i went and tried it out on my WinXP laptop, and it worked. Is there a diff with how Java is interpreted between diff op. systems?? i don't think it is the IE version, because i updated the ME box to IE6, which is being used on the laptop. Ne input iz appreciated, thanx

...is there a way to get current java plug ins??

How to know enhancements in the JDK when a new version is released?

Hello:
Java is releasing new versions of its JDK frequently. So, I would like to know what new features bring each version of JDK. I mean, I've just found this page: [http://java.sun.com/j2se/1.5.0/docs/guide/language/]. This page has documentation about enhancements in JDK 5 and also some examples of this enhancements.
However, I didn't find a page which can show me the enhancements in JDK 6. I mean, Java will continue releasing new versions of JDKs in the future. My question is, how a java programmer can update his knowledge about new features that will bring future versions of JDKs?. Is there any subscription or something like that in order to get notifyed and be able to learn what's new on every new version of JDKs?.
Thanks for your answer.
Bye.

A quick google search turned up [this page|http://java.sun.com/javase/6/webnotes/features.html], which seems to have it all.
Note that there is no direct equivalent to the page you linked to (language changes), because Java 6 didn't have any major changes in the Java language, while Java 5 introduced quite a few of those (generics, enum, annotations, ...).

Did the markup for java applets change with version 4.0.5

Starting with Safari version 4.0.5 java applets are not rendering correctly. The Java coffee cup loading image pushes the actual content down. Was the applet tag markup changed with this release?
Take a look at the following example:
http://tinyurl.com/p27vpq
or
http://preview.tinyurl.com/p27vpq
FYI, 4.0.4 displays correctly.

Ok...
First, try a different user account with Safari and see if the same thing happens. If it does then it's a system wide issue, not just your user account.
From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
Go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
Web pages now include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon cache using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
Relaunch Safari.
If you still have problems, go to the Safari Menu Bar, click Safari/Preferences. Make note of all the preferences under each tab. Quit Safari. Now go to ~/Library/Preferences and move this file com.apple.safari.plist to the Desktop. Relaunch Safari. If it's a successful launch, then that .plist file needs to be moved to the Trash.

How to load an applet with older version of JRE?

Hi All,
I'm writing an applet which should read the username from the user's system using System.getProperty("user.name") method. I've JRE 1.4.2 in my browser, and it's throwing a AccessControlException whenever the applet is trying to read the "user.name" system property. So, I want to load this particular applet with an older version of JRE, say JRE 1.3. I've tried various approaches like,
<jsp:plugin type="applet" code="LoginApplet.class" archive="login.jar"
jreversion="1.3" iepluginurl="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
</jsp:plugin>
and also tried OBJECT tag,
<OBJECT
classid="clsid:CAFEEFAC-0013-0000-0000-ABCDEFFEDCBA" codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0"
width="200" height="200" align="baseline" >
<PARAM NAME="code" VALUE="LoginApplet.class">
<PARAM NAME="archive" VALUE="login.jar">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
<PARAM NAME="scriptable" VALUE="true">
No Java 2 SDK, Standard Edition v 1.3 support for APPLET!!
</OBJECT>
I've not tried the simple APPLET tag because we can't specify a java plugin using the APPLET tag.
In both the above methods, I'm still getting AccessControlException. In Java console, I'm seeing Java Plugin as 1.4.2.
Can someone tell me is it possible to read the "user.name" system property from user's machine using Applets? If yes, how?
Thanks,
Tarun.

Applets are prevented from doing certain things - reading data is one - to maximize security. You can either add permissions to the computer that the applet is running on, or you can sign the applet.

JDK 1.4.2 version for Windows Server 2003/x64 on Intel Xeon 64 bit processo

Hi,
I'm currently installing a SAP Netweaver Server on a Windows Server 2003/X64 (Intel Xeon CPUs).
The server requires a JDK 64 bit with minimum version 1.4.2_09. Version 1.5.0_00 and higher are not supported by SAP.
I have searched on the J2SE 1.4.2 download page and I haven't found any windows 64 bit except for Itanium processors.
SAP mention clearly on its web portal that it supports Windows Server 2003/X64 64bit with Sun JSE 1.4.2 64 bit.
Any help?
Thanks,
adaif

Hello,
I ran into the same problem searching for the 1.4.2 JDK for Windows x64 platform and found this discussion post. It was helpful!
Could you tell me where to download the JCE policy files from? Do they need to match the same JDK version (1.4.2)?
The Install Guide for SAP NetWeaver 7.0 SR3 Java on Windows MS SQL Server says to download the JCE policy files for your platform (Windows x64) from http://java.sun.com/javase/downloads. But I could only find jce_policy-6.zip. Is that the right JCE policy files for Windows 2003 x64 64bit platform for SUN JSE 1.4.2 64bit?
Thanks,
Asif

Jdk download 1.3 version

hello,
I'm enhancing an existing project which uses JDK 1.3. Where I can find or download this version of JDK?
tnks,
natz

[_Google is your friend_|http://www.google.ca/search?hl=en&q=JDK+1.3&btnG=Search&meta=]
Unless you have a very good reason otherwise you should consider upgrading as part of this project. 1.3 has been EOLed (obsolete) since December 2006.

Applet times out - version 12.1

My irpt pages fail to load applets (iGrid) when I try to pull in report data. I can see in the transaction manager that the underlying transactions succeed, but my grid on the page, seems to have lost the connection to my transaction. I tried saving the report, and can see that the report file is saved with all rows. The report transaction takes 40 minutes to run. Please help.

Ajitha,
let me first ask: Does the report really needs 40 minutes to process? Are there any means to enhance the performance? How many rows are retrieved?
Is it necessary to start the report execution online? Would it be an option to start the execution using a scheduled job? I can't imagine someone waiting 40 minutes in front of the screen to see the results.
However, if the report should be started manually, it may be an option to split the report execution and the display of the result. You can start the report, and it processes the result and writes it to a file (or database table). A separate iGrid applet can periodically check if there is something to display (reading the file / table contents). If nothing is to be displayed, the default message "No Data available" is displayed, or you can set a user defined message "report is process" or something.

Java JDK versions on Mac OS Lion

I was just looking at the JDK on my Mac with Mac OS X 10.7.3 and it looks like I have different versions of the JDK around.
That's what I have
/Library/Java/JavaVirtualMachines/1.6.0_29-b11-402.jdk
/Library/Java/JavaVirtualMachines/1.6.0_31-b04-411.jdk
/System/Library/java/JavaVirtualMachines/1.6.0.jdk.
Why is that messed up ?
I checked to what I'm pointing and I get that
/usr/bin/java points at /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
/System/Library/Frameworks/JavaVM.framework/Versions/Current points at /System/Library/Frameworks/JavaVM.framework/Versions/A
Is that ok ? How can I check that I'm really using the most recent version of JDK, in this case /1.6.0_31-b04-411.jdk ? Should I remove redundant JDKs, and if yes what and how ?
Thanks.

Hey guys,
Sorry in advance if my question is a bit uncalled for in this thread.
Somehow I have not managed to get the latest version of Java (1.6.0_31) installed on my MacBook.
According to JavaTester.org I have version 1.6.0_29 which is confirmed by my Java Preferences Panel.
The only 2 versions listed in the panel are 1.6.0_29 (64-bit) and 1.6.0_29 (32-bit)
The webplugin check from firefox states that 'Java Applet Plug-in" is not up to date.
Firefox Add-on Tab says I have 'Java Applet Plug-in' version 14.0.3
Oracle.com says the latest version of Java is Version 7 Update 3
Java.com says the latest version of Java is Version 6 Update 31
Furthermore Java.com says updates will be automatically download through 'Apple Software Update' but it shows no sign of an update.
What's wrong? What is the latest version of both Java JDK and Applet? How can I fix this?

Java JDK Versions?

I am installing 11g XE, Weblogic, Forms & Reports, and SQLDesigner for a class and I don't understand why it keep whining about needing obsolete JDK versions. We all know there was a big uproar over Java security issues over the past few years so I don't understand why this software would be complaining when I try to tell it to use the current JDK version. Isn't Java JDK always written to be backward compatible? What about the real installations of this software? Or is the JDK version irrelevant if the JRE is up to date?

Problem Launching Java Applet with Plug-in: Version 1.4.2_01

Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,
Mike Coucke
Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

I'm not a Java expert, so this may be more information than you ever wanted to see.
Once again, I hope that you can help. My experience has been that I usually have some obscure option set incorrectly and that causes me great grief.
Thanks fo your help,

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,
Jeff Hall

Hello Jeff:
So far, I have been unable to launch a LOPARC session. I repeatedly
get the following error message:
"Exception: java.lang.ClassNotFoundException: LPRemote.class"
My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
using Java Plug-In version 1.4.1 and received the error message. I went
to the Sun website and downloaded/installed Java Plug-In version 1.4.2
and still get the message.
Before I try to launch LOPARC, I can select Tools->Sun Java Console from
IE's pull down menu to check my Java Plug-In version. When I try to
launch LOPARC, I get the following message:
"Applet(s) in this HTML page requires a version of Java different from
the one the browser is currently using. In order to run the applet(s)
in this HTML page, a new browser session is required, press 'Yes' to
start a new browser session." If I select 'No', I get the following
message: "Java Plug-in detected JRE collission"
If I select 'Yes', a new browser window opens and then I get the first
message above.
Can you help?

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

Hi Mike,
I see this in your logs:
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS
Proxy Configuration: Manual Configuration
Proxy: http=proxy,https=proxy,ftp=proxy,gopher=proxy
Proxy Overrides:
I just helped my Dad set up his computer with a new
cable modem, and had the situation where we couldn't
access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?

How to know which bit version (32 or 64 bit) of jdk

hi,
i have installed java in my system and i would like to know whether it is 32 bit platform or 64 bit plaform of jdk.
by using
java -version
we can know the jdk version ,in the same way do we have any command to know the bit version ?
could you please let me know how to do that ?

I think we can find the bit size base on the dierctory under which it installed. See some details here:
Java 1.1.8 installs in /usr/jdk_base
Java 1.2.2 installs in /usr/java_dev2
Java 1.3.0 installs in /usr/java130
Java 1.3.1 64-bit installs in /usr/java13_64
Java 1.3.1 installs in /usr/java131
Java 1.4 64-bit installs in /usr/java14_64
Java 1.4 installs in /usr/java14
Java 5 64-bit installs in /usr/java5_64
Java 5 32-bit installs in /usr/java5
