Installing JRE 1.6

I was wondering about bundling the JRE with an Installer.
Can someone point me towards information on how this can
be done? If it can be done?
I would like to eliminate the step for downloading and
installing a jre, and incorporate it into my installer if possible.
Thanks,

Read the Sun Licensing agreements, I'm not sure that is a supported way for the JRE to be distributed.

Install JRE 1.5.12 in the PI 7.0 server

Hi Gurus,
We are planning to install JRE 1.5.12 in the PI 7.0 server with Service Pack 11, whereas currently it is 1.4.2.
Please note we will not remove the 1.4.2 version from the PI Server but will add this new version as well. What will be impact of installing JRE 1.5.12.
Regards
R.Ragu

Hi,
When you install the 1.5.12 , this will over write the 1.4.2, ther will not any problem while installation.
once you do this 1.5.12 will be in use and if u have java version greater than 1.4.2, some mapping icons will not be in active and runtime problems can occur

Java Web Start Version 1.0 doesn't found installed JRE

I would like to try some demos from http://java.sun.com/products/javawebstart/demos.html
After I clicked on image receive next page with message "In order to launch the requested application, you will need to download Java Web Start Version 1.0 - This installation is a one-time process."
And after click "Download now" me propose download JSE and install.
But I already have installed JRE!
This is from command line java -version:
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode)
I have try from opera and firefox.

set JAVA_HOME to jdk and not jre.JAVA_HOME is for other applications to find the java libraries inside jdk
Example:
JAVA_HOME=C:\Program Files\Java\jdk1.5.0_05

Install JRE and OpenJDK Side-by-Side [Unecessary - So Solved]

As far as I know this is impossible, but if there is a way to install JRE and OpenJDK side-by-side, that would be great.
The reason I would like this is that there is a specific webserver I access that simply will not work with OpenJDK. It's a known issue that may or may not be fixed any time soon. On the other hand, I would like to install freeCAD, but this depends on OpenJDK and not JRE.
So as of right now, there is no way for me to have freeCAD installed and access this webserver. Now if JRE and OpenJDK were installed side by side, then this wouldn't be a problem. The other option, is letting users install freeCAD with and OpenJDK or JRE dependency, whichever best suits them.
Is anybody else in a similar boat as this?

Where do you see this requirement? I don't see anything that specifically depends on openjdk6. The only java deps I see are in opencascade. It depends on java-runtime and makedepends on java-environment, which can be satisfied by jre + jdk.
When I went to install, it was forcing me to install OpenJDK and uninstall JRE.

Detecting and Installing JRE

Hello
I'm a setup developer, and I'm tryng to detect from my setup program if the JRE is installed, all that by code, searching the registry whatever, then if it's not installed launch a Silent mode installation of JRE, But I don't know how to do it
How you can detect the installed JRE ?
How you can install JRE in silent mode?
Thanks

Can you detect JRE ?
The answer is yes. You have to read the registry and look for the uninstall string ( if you are using the 1.5.0 beta1 that got released today ) this is the registry value
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{3248F0A8-6813-11D6-A77B-00B0D0150000}
and the string is
MsiExec.exe /I{3248F0A8-6813-11D6-A77B-00B0D0150000}
look for these registry keys and you have detected the JRE
Is there a silent installation ?
Yes the command is
<jre>.exe /S /V" /qn"

Insufficient memory error while installing JRE 1.2.2

At the moment I am having some problems installing JRE 1.2.2 on a HP proliant DL380 G3 machine (with two XEON 2.8Gb processors) with windows 2000 SP 3 installed. The error is �Insufficient memory available to run setup. Close any programs�.. bla bla. Error 111�. While the machine has 4Gb of memory installed and only 200mb is in use.
I have tried 1.2.2.011 (Pentium 4 bug solved) and 1.2.2.014, both with the same result. Unfortunaly I need the 1.2.2 and can�t �switch� to version 1.3 or 1.4.
PS I also experienced almost the same problem while installing Oracle 8.1.7 on the same machine. And solved this by renaming symcjit.dll to symcjit.old and use the next installation options : JRE_MEMORY_OPTIONS=-nojit -ms64m -mx128m
Has anyone seen this problem and solved it or is there any way to give some additional options to the JRE installer?
Thanks in advance,
Frank Zomerdijk

I found a bug report at: http://developer.java.sun.com/developer/bugParade/bugs/4643265.html
And there by the "work a round";
In order to install j2ee onto your server (with 4Gb or more) you might use one of those:
1) Pull some DIMMs out of your server till the memory is less
than 4g. Install j2ee and than put the DIMMs back.
2) Install j2ee on the other machine and than just copy
installed directories over to your server.
I will test the second option tomorrow.

J2sdk-1_4_2_04-windows-i586-p.exe didn't install JRE correctly.

I realize that j2sdk-1_4_2_04-windows-i586-p.exe didnt install JRE probably.
Server folder which is used for Java HotSpot Server VM was not found in C:\Program Files\Java\j2re1.4.2_04\bin.
Hence, i need to manually copy the folder D:\j2sdk1.4.2_04\jre\bin\server to JRE location.
I was wondering is this the correct way to do so? anyone of u have encounter this problem before?
thank you.
regards
yancheng

If a previous version of the JRE is installed, remove the previous JRE and install the j2sdk 1.4.2_04 JRE.

WebStart not recognizing installed jre

I have problem with WebStart - I'm not able to run ANYTHING with my installed jres.
I have two JREs installed. One is 1.4.0rc, second 1.4.1beta1. Yes, I know that both of them are not final releases, but there should be a way to run webstart app even with them, doesn't it ?
I'm using
<j2se version="1.4*"/>
No luck. I have also tried 1.4+, 1.4.0-rc, 1.4.1-beta - every time it dumps out.
Web start is taken from 1.4.1beta1 (which means it is 1.2beta).
javaws.cfg follows
javaws.cfg.jre.0.platform=1.4
javaws.cfg.jre.0.location=http\://java.sun.com/products/autodl/j2se
javaws.cfg.jre.0.product=1.4.0-rc
javaws.cfg.jre.2.path=c\:\\java\\jre1.4.1b1\\bin\\javaw.exe
javaws.cfg.jre.2.platform=1.4
javaws.cfg.jre.2.location=http\://java.sun.com/products/autodl/j2se
javaws.cfg.jre.0.path=C\:\\Program Files\\Java\\j2re1.4.0-rc\\bin\\javaw.exe
javaws.cfg.jre.2.product=1.4.1-beta
Table in WebStart preferences:
1.4 1.4.0-rc http://java.sun.com/products/autodl/j2se C:\Program Files\Java\j2re1.4.0-rc\bin\javaw.exe true
1.4 1.4.1-beta http://java.sun.com/products/autodl/j2se c:\java\jre1.4.1b1\bin\javaw.exe true
Has anybody any idea what is happening ?

The easiest thing to do is to run the application amanger, go to preferences/java and edit the lines that say
1.4.0-rc and 1.4.1-beta. You can change them directly in the table to say 1.4.0 and 1.4.1 and then javaws will think they are fcs versions.

Want a code to check & install JRE automaticallly without user intervention

hi
I am trying to run an applet on a machine that is not having JRE on it.
want a code that will check for such condition and install JRE automatically.
If JRE is already present then it should check for required version and enable it also.
please help in this regard.
thanks in advance
Santosh.

The ability to detect the jre at the update level, as well as the ability to install a specific version are only present if the DT plugins are installed.
These plugins only exist for windows and are only part of the 6u10 (1.6.0_10) versions of java.
The javascript you show uses an undefined minimumVersion variable.
also note, you cannot use the wildcard '1.5.0*' in the call to isWebStartInstalled (which takes minimumVersion arg)
if fixed, this code would still not work as you want, since clients with 1.6.0 or later would sail straight thru and launch.
I suggest replacing isWebStartInstalled() with deployJava.versionCheck('1.5.0*') .
then on systems with the plugin installed, if no 1.5.0* version is installed, the latest 1.5.0_XX will be installed before launching the app.
(assuming the app has also <j2se version=1.5/> or equiv.)
on systems w/o plugins installed, the latest version of java will be installed, and it will be up to javaws auto download to get 1.5.0* version.
this could still have problems, especially on platforms not supporting the plugins (non-windows) , since code keeps checking for '1.5.0*', and installing only latest, so you would want to wrap install with something to prevent repeated attempts to install:
if (deployJava.versionCheck('1.6.0+') && !deployJava.isPluginInstalled()) {
---- don't do any install here - ---

Help Installing JRE, Locked Folder?

I am trying to install JRE on a brand new computer I just built. It has WinXP SP2 Media Center Edition installed as the OS. I am using Firefox for a browser... Everytime I go to install, web based and locally from the downloaded installer I get the same error message everytime at the end of the installation.
JRE could not be installed in to the folder because it is locked. Please unlock the folder or close the application that is using it.
I've tried everything I can think of, I can't think of any apps that I have running that would be causing a conflict... esspecially since I have tried my own install paths on different drives. Can someone please help me with this? Thanks!

This search appears to suggest that there's a problem with the .dll's in your machine. You might try doing a check of the system files.

How to run java exe files without having to install jre

Hi all i want to run a java application. i already converted the jar file to exe using Launch4j but the problem is that i want to run the application on other computers without having to install jre. please, is this possible and if yes, how can i do that. Thanks alot in advance

The Launch4J website should explain how to bundle the JRE. I've not really used it myself though. If you can't get it to work you could try the launcher I use:
http://www.megaupload.com/?d=FYZAVM77
which comes with instructions. Or:
http://sourceforge.net/projects/javaround
Both of which are really easy to use.

Error installing jre 1.4.0_01

I have installed and installed the sdk and jre version 1.4.0_01. To cleanup my environment I uninstalled all of my java products and began re-installing them. When I tried to install jre 1.4.0_01 (this is the first product that I tried to re-install) I get a message from the installer
"You already have the Java 2 Runtime Environment, SE v1.4.0_01 already installed on this machine...."
I have went thru the registry and deleted any reference to java 1.4.0_01. Any help would be great.
Thanks.

Yep, i had installed the JDK, but when I found out that the plug-in app was not operating properly in the control panel, I figured something had gone wrong. I uninstalled everything and tried installing just the JRE, when I noticed this error.
I used Iolo's system mechanic to try and clean the registry and run all kinds of analysis and cleaners on my system.
No dice, still have that problem.
I believe I may blow away windows and move to a Linux desktop

WebStart 1.4.2 doesn't find installed JRE for 1.4.2 ?

I have installed J2RE1.4.2_04. As far as I can tell, it works just fine and there are registry keys set for
Java Runtime Environment for 1.4 and 1.4.2_04 which are set to the same thing. However, when I
run my webstart app, I get an error with the general information that "The application has requested a
version of the Java 2 platform (JRE) that is currently not locally installed. Java Web Start was unable to
automatically download and install the requested version. The JRE version must be installed manually."
Having turned tracing and output on, I look in the log and see
javawsApplicationMain: Installed JRE: null
So, for some reason, WebStart doesn't think I have an installed JRE. Could someone tell me why?
I have tried various incantations of version, such as
<j2se version="1.4.2_04"/>
<j2se version="1.4.2"/>
<j2se version="1.4.2+"/>
<j2se version="1.4.2*"/>
All of these result in the same error. If I try either of
<j2se version="1.4+"/>
<j2se version="1.4"/>
WebStart recognizes that I do in face have a JRE installed, but then I have other problems. I would
prefer to get the 1.4.2 problem fixed first since I require 1.4.2 and some boxes have 1.4.1 on them.
Thanks for any ideas!

This is confusing and done poorly in my opinion but the only "versions" of Java 2 are 1.2, 1.3, and 1.4 (1.5 is coming). If you specify anything past those (as your first four examples do), Web Start assumes a product specific version and you have to provide a URL to download it. Even if it is on the machine, Web Start downloads the version and stores a separate copy of it.
See http://java.sun.com/products/javawebstart/developers.html#auto for details.
I think the only thing you can do if multiple versions of 1.4 are installed is go into Web Start preferences and uncheck the box so it is not enabled.
