JRE-6 and J2RE-1_4_2_13.

February 04, 2006
Hai!
What is the difference between jre-6-windows-i586.exe and
j2re-1_4_2_13-windows-i586-p.exe?
Best Regards,
Kartheek D. N.

Hai!
The URLs are -
1. http://java.sun.com/javase/downloads/index.jsp for JRE-6 and
2. http://java.sun.com/j2se/1.4.2/download.html for J2RE-1_4_2_13.
Read the README docs, it's almost the same.

Linux 9.0 and j2re-1_4_2_06 or jre-1_5_0_01 HELP Please!

I have just started using Linux 9.0, and immediately installed the Firefox Web Browser and to get the best out of this installed j2re-1_4_2_06, made the link to the plugin as required and found Firefox did not seem to recognize it. I then tried to install Limewire and was informed that I could not as no jvm was installed.
I upgraded to jre-1_5_0_01 and did the same with the plugin after deleting the one installed at my previous atempt and Firefox will not start at all in the desk top and if run in a shell it just opens a shell window and closes it again. I tried to install Limewire again and was told the same no jvm message.
Can someone help please?

I have now deleted all plugins from the fiefox plugin directory but just by clicking move to trash on a right click, I then put all of them back using the cut on right click and used the rm command in terminal
to delete them all.
I should say that I use Red Hat 9.0 here not Linux 9.0,.
I then installed the Self-extracting Binary File and end up with the same problem, the only difference is that I installed it to my home folder, not /usr/java and I still get the same message.

J2sdk and j2re in Mac OS X 10.3

Dear Developers,
I'm quite new to java and need some help.
I am a development support staff, and currently doing software adapation to Mac OS X 10.3. The software runs on j2sdk and j2re which are already available in OS X.
I need to copy some files to /j2sdk1.4.2_06/jre/lib/ext. In Windows and Linux/UNIX version I have no diffculties in finding the sudirectories of the SDK / RE (i.e. ../j2sdk1.4.2_06 for example) but I can't find those folders in Mac OS X.
Any of you have experiences in OS X 10.3 Java that could help me on this?
Thanks
.V.

I need to copy some files to
/j2sdk1.4.2_06/jre/lib/ext. In Windows and Linux/UNIX
no you should not.
Put the files on the application classpath instead.

Jre-6u22 and greater breaks java webstart 1.4.2_11 application

I have a java web start application that actually worked in jre-6u18, but but definitely breaks with the jre-6u24 and I suspect any other jre greater than jre-6u21. The reason I suspect this is because a buddy of mine also experienced a similar issue and determined the breakage for him was between jre-6u21 and jre6-u22. I have tested in pristine environments and found breakage between jre-6u18 and jre-6u24 only because I do not presently have any of the versions in between to test.
Here are the details:
The JNLP file is configured to autodownload <j2se version="1.4.2_11*" href="http://java.sun.com/products/autodl/j2se" initial-heap-size="64m" max-heap-size="256m"/>
The launch attempt successfully downloads and installs this JRE in both 6u21 and 6u24.
It has been re-written from spec="1.0" to spec="1.5" and when I try to run it directly with the 1.4.2/javaws/javaws.exe it breaks with error stating that it is incompatible with spec="1.5" and to use a more up to date JVM.
When launched with jre-6u18 it installed the j2re1.4.2 and continued to fail to launch the application initially, but succeeded to launch it on a second attempt.
When launched with jre-6u24 it installed the j2re1.4.2 and ultimately failed on any consecutive attempt as well as the initial attempt usually with the following console output:
Java Web Start 1.6.0_24
Using JRE version 1.4.2_11-b06 Java HotSpot(TM) Client VM

     at java.util.ResourceBundle.throwMissingResourceException(Unknown Source)
     at java.util.ResourceBundle.getBundleImpl(Unknown Source)
     at java.util.ResourceBundle.getBundle(Unknown Source)
I compared the differences between the properties of the shortcuts that got created for the successful one and the unsuccessful one and they seem identical except for a minor cache difference as follows:
C:\WINDOWS\system32\javaws.exe -localfile "C:\Documents and Settings\smithj\Application Data\Sun\Java\Deployment\cache\6.0\39\3a08ece7-75d85e43"
C:\WINDOWS\system32\javaws.exe -localfile "C:\Documents and Settings\smithj\Application Data\Sun\Java\Deployment\cache\6.0\39\3a08ece7-5657ebe9"
Has anybody else experienced this type of breakage? Does anybody else have an answer, solution, or suggestion other than "upgrade your 1.4.2 app"?
thanks in advance.

Openjdk, jre, Frostwire and Firefox

Didn't see a specific place to post this nor did I see it spoken about anywhere through search and it's not a problem I need help with.
I thought it might be helpful to others who may be experiencing the same problem/s.
On the current install I had installed Frostwire and it pulled in openjdk, which is fine.
I also use Firefox, which openjdk works fine with,,,, in most instances.
I'm a member of a game site called Pogo.com.
Seldom go there but anyway, my girlfriend wanted me to play against her in a game room there last night.
I go there, log in, try to go to the game room and Firefox crashes, rather flamingly,,, repeatedly.
I fire up the other box I play on with distro hopping and go to the same game site.
Firefox performs marvelously,,, with sun jre.
I had seen posts where others had stated Firefox crashes on them on occasion.
Out of curiosity, I rm openjdk and pacman -S jre.
Firefox works fine in the game site, however, now Frostwire won't start.
The fix for me was to leave sun jre installed and then:
nano /usr/share/frostwire/runfrostwire.sh
scroll to the line:
look_for_java()
just below that is the line I edited so that it reads:
JAVADIR=/opt/java
Save and exit.
Frostwire as well as Firefox now perform fine.
A few lines further down is the line:
JAVADIR=/opt
that is part of the search path.
One could simply add the /java to there as well if they wished to change back to openjdk for whatever reason in the future and leave the first line mentioned above alone.
*Note: I plan to bring this to the attention of whomever takes care of the Frostwire package as it seems a very simple fix to edit the run.sh before rolling by simply adding /java to the line I pointed out,,,, as soon as I figure out who they are that is..:D

For openjdk6 and the Firefox crashes see FS#15550. Regarding the second part of your post (about Frostwire), /etc/profile.d/jre.sh appends "/opt/java/jre/bin" to your PATH variable and also sets JAVA_HOME accordingly. This script is sourced at login, so either logging out and logging back in or running 'source /etc/profile.d/jre.sh' in a terminal and then executing 'frostwire' from within the same terminal should work.
I'm the current maintainer of Frostwire in [community] and, while your proposed solution is simple and would allow Frostwire to run correctly when jre is installed and java is not in the user's PATH, other Java applications would still not function correctly until /etc/profile.d/jre.sh is sourced. Therefore, I don't see a reason to tweak runFrostwire.sh. As long as java can be found in PATH, it will work.

HT5246 The above info is confuses me. I thought this trojan horse affected those who had Java (JRE) up and running i.e.,Safari security Java checkbox enabled. I also believed this Trojan horse affected those using Snow Leopard. Clarify please.

The above info re the Flashback removal tool confuses me. I thought this trojan horse affected those who had Java (JRE) up and running i.e.,Safari security Java checkbox enabled. I also believed this Trojan horse also affected those using Snow Leopard. Clarify please.

There are several variants of the trojan. The first ones were released as installers for Adobe Flash and therefore did not require you to have Java on your system. Later variants took advantage of a Java vulnerability and could install themselves by simply visiting a rogue Web site. Therefore, even without Java installed if you had run a rogue updater for Adobe Flash or Reader, then you might have installed the trojan.
The trojan also affects Snow Leopard and prior versions of OS X (so far the code is known to be intel-only, but this is unconfirmed), but Apple has only issued patches for supported versions of the OS (version 10.6 or later).
Apple's removal tools run in OS X 10.6 or later if you instlal the Java update, and the standalone removal tool is for Lion only. Why Apple does not offer options for other operating systems is beyond me, but that's the way of things. Right now there are other tools you can use to check for and remove the malware on versions of OS X that Apple does not support: http://reviews.cnet.com/8301-13727_7-57413811-263/flashback-malware-removal-tool -roundup/

JRE 6U35 and JRE7U7 improperly install (via MSI in GPO) on top of existing

Hello,
Within my environment, we occasionally have to push out software updates (MSI based installers) via group policy. We also install the latest JRE as a part of our base install when systems are built. In the past, this has worked without issue. The previous behavior of the MSI installer when used within a GPO was to NOT install if the current (or newer) version of the JRE was already installed. I've confirmed that with both JRE 6U35 and JRE7U7, if a system already had say JRE6U35 installed (silently via msiexec /i "jre1.6.0_35.msi" /qn) as part of the base install, it would work just fine, until the system was restarted, at which point, if it was within an OU that had our GPO to apply the latest JRE (in this case, the EXACT same installer, same version etc) the Software installation policy would actually run (which it shouldn't and didn't with previous JRE installers) and would mess up the JRE on the system. In add/remove programs, the expected JRE version would be listed, and the control panel applet icon would be present, but the browers (any browser) would act as though the JRE was not installed and clicking on the Java control panel applet would generate a message that says something to the effect of "Application not found". Also, trying to remove the JRE via add/remove programs also seems to cause an "Application not found" error message. I've found that I had to remove a registry key (though I can't remember it right at this moment) to get rid of the "Application not found" error messages before I can manually uninstall the JRE and reinstall properly.
I think there's something wrong with the MSI installer, namely that it doesn't seem to check properly for existing versions of the JRE when processed via a Software Installation GPO.
My current work around is to exclude JRE from the base install, allowing our GPO to perform the installation, (which works, even after several restarts) but that's not ideal and it's not how these installers used to work.
OS - Win7 Enterprise 32bit AND 64bit
JRE versions - 6U35 and 7U7.
Please advise.

I have encountered a similar situation as well. Deploying new systems with OEM (factory) installed 64-bit Windows 7 SP1 Professional operating system that also has a pre-installed Java on the system. Have a GPO based install for Java 7 Update 7 which seems to install just fine (over an older version of Java 7) but subsequent attempts to use Java in an IE9 browser results in no Java. If you go to the Oracle (Java) page to show what version of Java is on the system it tells you to download the latest. A similar problem happens with the install of Java 6 Update 35 as well.

Why do JRE 8u20 and 8u25 install as static?

Why do the installs of JRE 8u20 and 8u25 seem to be hard coded to install as static?
These versions end up in their own folders under Program Folders.
C:\Program Folders\Java\jre1.8.0_20
C:\Program Folders\Java\jre1.8.0_25
The earlier JRE 8's like 8u5 and 8u11 installed to "C:\Program Files\Java\jre8".
According to this information (Installing With a Configuration File) the install should default to not static.
Attempts at setting "STATIC=Disable" in a config file for the exe install or on the msi command line will still result in static installs.
Is Oracle switching direction again and going back to the old way of leaving all versions on the system?

Oracle has made some changes as you can read in the Java SE 8u20 release notes (Java™ SE Development Kit 8, Update 20 Release Notes):
Java Installer Changes
A new Microsoft Windows Installer (MSI) Enterprise JRE Installer which enables user to install the JRE across the enterprise, is available. See Downloading the Installer section in JRE Installation for Microsoft Windows for more information. The MSI Enterprise JRE Installer is only available as part of Java SE Advanced or Java SE Suite. For information about these commercial products, see Java SE Advanced and Java SE Suite.
In other words you have to buy Java SE Advanced or Java SE suite to download the MSI Enterprise JRE Installer through My Oracle Support (MOS).

How to get the Most RECENTLY installed JRE path and version ?

Hello Experts,
I am working on Installshield, and for some purpose, I need to get the MOST RECENTLY installed JRE version and Path. Now I have two choices :
1. Go into the directory " C:\Program Files\Java\" and get the most recently changed directory, ( that will be the installation directory of the most recently installed JRE ). And then search in the registry under : HKEY_LOCAL_MACHINE/SOFTWARE/JavaSoft/Java Runtime Environment/ and look for the version which is having
the value of the key INSTALLDIR as the above found Installation Directory.
But in this approach, I'll never find the Installation dir or version, if the JRE is installed somewhere else than the default location.
2. Now this is the reverse. I first search in the registry, and get the Installation Directories of all the versions installed in the system, and then look at the file attributes ( may be by using some batch file ) and see which one is most recently installed.
My question is, is there any other way, by which I can get the most recently installed JRE's installation Path and version? Or can we trace it during the installation itself ? I mean when we install the JRE, it creates some log files in %TEMP% directory. Is it possible to trace the version and installation directory of the most recently installed JRE from the log file ?
Thanks
Gagan

Rendering times are pretty much based on processor speed if I have that right. Not much you can do about that other than buy a new computer. Your day to day work in the finder and accessing of files would be faster with your boot drive internal. One thing you can do is ensure your FCP System Settings are on the fastest disk you have. If you put a pair of drives internal and made a RAID volume for them you would improve your write speed when capturing and for any other read/write operations. You would have to be sure you kept that backed up properly because you double the odds of a failure when two drives spread the data between them. There are many RAID options.
You could also bump up the RAM but you'd have to look at your processes to see if you are being limited by RAM. I'm guessing not but it's not impossible. If you are accessing scratch disks due to RAM limitations that would be one thing you could do.
I would never bother connecting an external via USB if there was an esata or firewire option. I use an esata card internally to give me access to estata storage. I also keep an external FW800 drive for a mirror backup of my boot drive. All my data and booting is internal with all my backups external. Each internal has an external and I have additional externals that I keep off site to protect against fire and theft.

What is the difference between JRE,JVM and JDK?

plz reply me to the following question
(1)what is JRE,JVM and JDK?

The JRE is a java distribution for running java programs. It does not contain the development tools needed to compile and debug java programs.
The JDK is a java distribution for both running and developing java programs. In includes the deveopment tools.
The JVM is part of both the JDK and the JRE. It is the 'engine' that executes java bytecodes, performs garbage collection and does just-in-time compilation.

JRE 5 and Mozilla-1.7.3 question

Is there anybody that can get Java 5 to work with mozilla-1.7.3.
I'm using Redhat Fedora core 2 and cant get the symlink solution to work on my updated mozilla. I have installed jre-1.5.0 and tried all previous versions with no luck. I'm really confused about this because I need a java enabled browser on my job. I think it has to do something with the gcc versions used to compile jre and mozilla, but nobody told me in the knowledge database. So perhaps I should wait for a newer version of Java and in the meantime don't update the mozilla. I've also considered installing firefox, but if the compiling versions is the problem, this won't help.

Go to this link http://dag.wieers.com/packages/j2re/
and download both j2re -- and mozilla-java-- pkgs and install both on the same time.
And woops ther u go. libjavaplugin_oji.so are installed in /usr/lib/mozilla/plugins dir and jre in
/usr/lib/jre
It the link is down google j2re i586 rpm.

JRE v6 and v7 no longer work in my updated 64-bit W7 HPE's 32-bit IE8.

Hello.
Since last week, my JRE/Java v6u34 stopped working. My 32-bit IE8 kept asking me to run it in protected mode or not which was weird since it never did that before: http://i.imgur.com/Tubsl.gif ... Then, Java didn't work. So I restarted IE8 and retried again to allow it. Java applets still didn't show up (shows an empty box with X icon, JRE console doesn't even run/load). I tried my 64-bit JRE v6u35 in 64-bit IE8, no problems with Java. I tried my 32-bit Mozilla's SeaMonkey v2.12 web browser and no problems with its Java. Why is my 32-bit IE8 having problems all the sudden?
I thought maybe my JRE installation was broken. So, I uninstalled it and reinstalled with the latest v6 (u35). Same results. I tried the very latest v7u7. Same problem. I tried uninstalling Java again, running JavaRa v1.16-23-8-12 (didn't find anything to remove), resetting IE8 options and clearing its caches), etc. I also tried disabling protected mode to see if it makes any differences when reinstalling and accessing a Java applet. Nope! I looked at my IE8's addons list and noticed jp2ssv.dll was still listed like:
Name: Java(tm) Plug-In 2 SSV Helper
Publisher: Control name is not available
Type: Browser Helper Object
Version: Not available
File date:
Date last accessed: Today, September 04, 2012, 1 minute ago
Class ID: {DBC80044-A445-435B-BC74-9C25C1C588A9}
Use count: 2030
Block count: 9
File: jp2ssv.dll
Folder: C:\winstuff\JRE6\bin
http://i.imgur.com/wvKdn.gif for a screen shot/capture.
I searched jp2ssv.dll on my computer, and it was not found. Even my uninstalled JRE removed its JRE location/folder. How do I remove this one from 32-bit IE8's addons list? Maybe this is the problem? What's going on?
Thank you in advance. :)

I think you are having the same issue I've been working on. I just posted about this here:
Newer JREs are not registering old JRE ClassIDs for all users
You can try the following.
* On a working user, export the key HKCU\Software\Classes\CLSID. Then import it for a failing user. Its not a real pretty solution. You should be able to narrow down exactly which subkey is needed by using Process Monitor or looking at your application HTML code where the JRE object is being called.
* If you can change the code, look for the OBJECT or EMBED tags and look what CLSID they are referencing. Change that CLSID to "8AD9C840-044E-11D1-B3E9-00805F499D93" allow it to work with the latest Oracle/Sun JRE installed.

Jre-6u24 and copy + paste in a java applet

Hi, I'm having trouble with jre and the applet at http://www.finnzymes.com/tm_determination.html . I can copy + paste to and from it using jre-6u23 (any subversion), but not with the jre-6u24 versions. Could someone confirm that this is the case and/or help me figure out what's up? I use this site all the time and currently have to launch windows xp from a virtualmachine just to use it!
Thanks!

I was having this problem also. It seems that since 6u24, copy and paste has been disabled in untrusted applets. To enable it again, add the following line to /opt/java/jre/lib/security/java.policy
permission java.awt.AWTPermission "accessClipboard";
I put it at the end of the file before the last closing bracket. I can cut and paste now

JRE, vista and IE7 problems

Java does not seem to run on IE7 except on microsoft's websites. The verify of installation on the Sun java website failed as well. I could not see any applet running. However, with other broswers such as firefox and opera, java worked perfectly. I updated my IE and JRE as well, but the problem was not solved.
I had already enabled the scripting under security, the plug ins in the
manage add-ons and under advance, java sun was enabled as well. My internet security settings is set to default.
I found out that the problem was caused by UAC. After disabling that troublesome device, java could be activated again. Is this a bug in java or in UAC?
Is there any other way besides disabling UAC or having IE7 protected mode : off?
Any solutions please?
Vista home premium

I'm having the same problem with IE7 running on XP SP2. All web sites that i visit the require JRE (Morningstar, Schwab, Marketedge, Sun Java Verify Site) return 'Jave Plug-In Fatal Error: Several JVMs running the same process caused and error. I'm running JRE 1.5.0_06. I've tried uninstall/reinstall of IE7 with no change. No problems running JRE on IE6 or Netscape. Does anyone know of any progress on this issue?

JRE versions and Browsers and Applets

Is there a way to assign a particular JRE version to a browser session through JavaScript or VBScript programatically so that I can run applets from different sources which need different JREs?
Basically I will have 2 links/buttons which will call two separate javascript methods to open two different browser windows to run two different applets running under different JREs
However when I start IE each 'session' of IE is assigned to one JRE, any way to overcome this?
TIA,
Raj

Martin thanks for your inputs
I am sourcing html pages from multiple sites and the html/applet tag is generated by those websites.
They do have the applet tag pointing to proper class-id of the java plugin.
However, the problem is with IE one family(session) of browsers are attached to one version of JRE plugin.
Here 'session' means: you open a browser and from within that browser you do go from a link or javascript etc. to another browser they are in same 'session'
I am working on dynamically setting JRE plugin version to different browsers.
Not sure I made it clear or confusing : )
Thanks
