Revision as of 17:59, 2 May 2011

Despite the page title, this page is for the Java 2 Standard Edition Runtime Environment, rather than the full-blown Java or Java Software Developer Kit / SDK. This is more commonly known as the Java Runtime Environment or JRE. The JRE provides an ability for programs written in the Java programming language to be launched from a web page and run in a web browser. There are many variations on Sun's (now Oracle's) JRE, in particular this page is for the Oracle Java Runtime Environment, previously known as the Sun Java Runtime Environment.

For security reasons you are encouraged to upgrade to the latest release. Bug Fixes of the Update Release Notes under each release: http://java.sun.com/javase/6/webnotes/ReleaseNotes.html. However, if you're running JRE 6 Update 10 or onwards and haven't disabled automatic updates then JRE should automatically be downloading and installing updates.

Java Runtime Environment (JRE) 6

Installer Versions

There are various versions of the installer:

  • Those from http://www.java.com/en/download/manual.jsp which are aimed at consumers. The versions available here are 'Windows 7/XP/Vista/2000/2003/2008 Online' (same as the 'Windows Online Installation' above) (jre-6u23-windows-i586-iftw-rv.exe) and 'Windows 7/XP/Vista/2000/2003/2008 Offline' (not the same as the 'Windows Offline Installation' above) (jre-6u23-windows-i586-s.exe). In versions prior to update 19 or maybe 18 the installer filename ending in -s.exe tried to download the Google Toolbar so this may still be the case with this version.

Uninstalling Old Versions

Older versions of Java did not uninstall themselves when new versions were installed. These older versions can pose a security risk even with newer versions installed. Older versions should be uninstalled unless they are required for some reason. Attempting to uninstall every old version of Java in the package definition can be very slow. Only include these uninstall commands in your package definition if there is a possibility that clients will have the older Java versions.

The patch-in-place mechanism was introduced in JRE 6 Update 10, so only versions before that need to be uninstalled.

Java Quick Starter

"Java Quick Starter" is described as a prefetching service that should make java applications start faster. But it has a drawback: it must be killed before uninstallation or installation fails, and uninstallation via msiexec does not seem to be smart enough to do this.

This is not a problem though, simply insert the following snippet into the very first of your install AND upgrade commands of the xml from the next paragraph. 

<install cmd='net STOP JavaQuickStarterService' >
  <exit code='2' />
</install>

This will stop the java quick-start service prior to installation or upgrade. In case it was already stopped (Errorlevel 2) the error is simply ignored. If you want to use it, be sure to remove the commands (%PROGRAMFILES%\Java\jre6\bin\jqs.exe -unregister') that disable the 'Java Quick Starter' from your package definition.

Although there seems to be no command line switches to allow/disallow the installation of "Java Quick Starter", the jqs.exe binary itself can be used immediately after installation in order to add/remove the "Java Quick Starter" service.

The following table shows the command line switches you can invoke with the jqs.exe binary: 

C:\Program Files\Java\jre6\bin>jqs -help
Usage: jqs <mode> [<options>]

The following modes are supported:
  -help         print this help message and exit
  -register     install JQS service and register browser startup detectors
  -unregister   uninstall JQS service and unregister startup detectors
  -enable       enable JQS service
  -disable      disable JQS service
  -pause        pause prefetching
  -resume       resume prefetching
  -version      print version of the associated Java Runtime

Options include:
  -config <config>      set JQS configuration file
  -profile <profile>    set JQS profile file
  -logfile <logfile>    set JQS log file
  -verbose <level>      verbose operation


This requires the Windows Offline installation package available from Sun. Note that a particular Java family install package does not remove already installed versions of another Java family, so JRE 1.5 and JRE 1.6 can coexist; all older 1.6 update versions (1.6.0 up to but not including the most recent version) are uninstalled by the following packaging (note that the update version seems to be no more reflected in the last number in the Uninstall ID).

Actually, with Update 10 and later Sun has introduced as default the so called "patch in place" update mechanism (see: http://java.sun.com/javase/6/docs/technotes/guides/jweb/otherFeatures/jre_install.html) which automatically removes the previous version of the same Java family (unless you turned off patch-in-place using the installer). So the line that tries to remove a previously installed Update 10 (msiexec /qn /x {26A24AE4-039D-4CA4-87B4-2F83216010FF}) is not strictly necessary (if you installed a 'Family JRE' and not a 'Static JRE').

Patch-in-place sometimes fails with "Error 25099. Unzipping core files failed", returning error code 1603 from msiexec. Sometimes installation will succeed on a later reboot without any intervention, but sometimes it continues to fail. As of December 2010, the root cause is not known, but Sun/Oracle suggests (at http://www.java.com/en/download/help/error_25099.xml) removing %PROGRAMFILES%\Java\jre6 before retrying installation. A fully-automatic workaround requires the ability to execute commands in response to particular error codes and thus may need to take the form of a batch program wrapped around msiexec.

Disable Automatic Update

JRE 6 Update 18 and Newer

Since approximately 1.6.18 / 6.0 update 18, Sun has included Java Auto Updater as a separate package that is automatically installed with the JRE. You can disable automatic updates by uninstalling the Java Auto Updater after the JRE is installed or upgraded, by adding the following to your package definition: 

<install cmd='msiexec /qn /x {4A03706F-666A-4037-7777-5F2748764D10}' />
<upgrade cmd='msiexec /qn /x {4A03706F-666A-4037-7777-5F2748764D10}' />
Older Versions

Automatic updates can be disabled with JAVAUPDATE=0 JU=0 AUTOUPDATECHECK=0; if these command line switches should not work for you, then you can alter the registry (read Adding Registry Settings for that) to disable autoupdate: 

[HKEY_CURRENT_USER\Software\JavaSoft\Java Update\Policy]

Another way to bypass Automatic Update is to use the MSI Installer. According to http://www.java.com/en/download/help/msi_install.xml you can 'extract' the MSI Package and pass the options as mentioned above (JAVAUPDATE=0 JU=0 AUTOUPDATECHECK=0). Worked fine for me with 1.6.18. 

<install cmd='MsiExec.exe /qn /i "%SOFTWARE%\Java1.6\jre1.6.0_18.msi" ADDLOCAL=ALL REBOOT=Suppress JAVAUPDATE=0 JU=0 AUTOUPDATECHECK=0'/>

JRE on 32-bit Hosts

The following installs the JRE and then removes the "Java Quick Starter" service; if you want to keep "Java Quick Starter" service then just remove the line with "jqs.exe -unregister", but remeber to stop/kill JQS before uninstallation. 

<package id="java6" name="Java Runtime Environment 6" revision="%version%" reboot="false" priority="100">
  <variable name="version" value="25" />
  <check type="uninstall" condition="exists" path="Java(TM) 6 Update %version%" />

  <install cmd='taskkill /f /im jqs.exe /im iexplore.exe /im firefox.exe'><exit code='0' /><exit code='1' /><exit code='128' /></install>
  <install cmd='%SOFTWARE%\jre\jre-6u%version%-windows-i586.exe /s REBOOT=Suppress' />
  <install cmd='%COMSPEC% /C if exist "%PROGRAMFILES%\Java\jre6\bin\jqs.exe" "%PROGRAMFILES%\Java\jre6\bin\jqs.exe" -unregister'>

Install JRE with msi without removing old version in a mixed 32-bit/64-bit environment

On 64-bit hosts installing the exe doesn't work. jre-6u17-windows-i586.exe is a 32bit app containing a msi, a cab and some other files. On a 32-bit host it unpacks in in c:\Windows\system32\config\systemprofile\AppData\LocalLow\Sun\Java\jre1.6.0_17\. On a 64-bit host it unpacks in c:\Windows\SysWOW64\config\systemprofile\AppData\LocalLow\Sun\Java\jre1.6.0_17\. The silent install on a 64-bit host is still looking for the msi in the *System32* directory.

So the best thing to do is to install the msi package. Copy the content of \Windows\SysWOW64\config\systemprofile\AppData\LocalLow\Sun\Java\jre1.6.0_17 on your server and install from it.

You should install both 32-bit and 64-bit java on 64-bit machines if you want a 32-bit browser being able to use java.

In this example, no uninstall of the old java versions as it is quite time consuming.

Installer Command-line Switches

http://java.sun.com/javase/6/webnotes/install/jre/silent.html gives the following list but it may or may not be complete:

  • /lang=<language ID>, if used, sets the localized language for the installer (see language IDs)
  • /s, if used, specifies a silent installation
  • INSTALLDIR, if used, specifies the drive and path of the installation
  • If INSTALLDIR is not specified, the installation will go into C:\Program Files\java\jre6 (default location).
  • REBOOT=Suppress, if used, indicates that if locked files are encountered the computer should not be rebooted. Most JRE installations will not ask for a reboot.
  • STATIC=1, if used, specifies a static installation. The default is for a Family installation.
  • SYSTRAY=0, if used, if set to zero, Java won't show an systray icon when loaded.

The following switches are deprecated for JRE 6 Update 10 and higher:

  • IEXPLORER=1
  • MOZILLA=1
  • ADDLOCAL=ALL
  • JAVAUPDATE=0
  • JU=0
  • AUTOUPDATECHECK=0

From the 'Java SE 6 Update 10 Release Notes': "Windows Regression when Using MSI Install Options

On Windows XP Pro SP3 (32bits), when installing JRE 6u10 or later and using MSI install options /qb or /passive, installation fails with Error 1606.Could not access network location 0.. The workaround is to not use the /qb or /passive options. Options that work correctly are /q, /qn (no UI), /qr (reduced UI), and /quiet (quiet mode, no user interaction). See 6764967 for details."

Java Runtime Environment (JRE) 6 Update 10

Sun has skipped 2 update versions and has released Update 10 as the versions replacing Update 7. Update 10 introduced some substantial changes, also in relation to the installation/uninstallation process we manage with WPKG: specifically it introduced a new binary "jqs.exe" and a service called "Java Quick Starter" starting it automatically at boot time.

Java Runtime Environment (JRE) 6 Update 7

This requires the Windows Offline installation package available from Sun. Note that the Java install package does not replace old versions, so JRE 1.5 and JRE 1.6 can coexist; all older 1.6 update versions (1.6.0 up to 1.6.0 Update 6) are tried to be removed (note that the update version is reflected in the last number in the Uninstall ID). Notice how the path string in the uninstall check has changed from previous version.

For the JDK, just change "jre" to "jdk" in the setup program's name and change "A77B" to "A78A" in the Uninstall ID.

For the JDK, we had to replace {3248F0A8-6813-11D6-A77B- with {32A3A4F4-B792-11D6-A78A-. This works and tested with Java6u7

J2SE Runtime Environment 5.0 Update 10

This requires the Windows Offfline installation package available from Sun. Note that the java install package does not replace old versions, so to accomplish a true upgrade, remove commands are required for the install/upgrade process.

Note that the class id of the remove section was incorrect in an early edition of this page - the last 3 digits should be 100, not 010.

Further Details

J2SE Runtime Environment 5.0 Update 5

First download the EXE package from java.sun.com, install it, and find an MSI package on your drive. Then use this MSI to distribute Java to other machines.

Note: When you use the *.exe file directly with command line switches as proposed by sun the installer waits forever for someone accepting the licence agreement.

Note that "install cmd" should be in one line; it was wrapped because it was too long to fit here!

Alternate Java 6 (JRE/SDK) Installer (seems very complicated)

This is my personal solution. Works properly for me starting from Java 6 Update 11. It works on Windows XP and Vista. 64-bit OS is supported as well as 32-bit OS. It also seems that Sun is not going to install each Java update into an independent directory. This will hopefully eliminate the need to uninstall previous versions manually.

Download

First of all download the offline installers. Do not download the new Online installers. It might work as well but I did not try it. After download you should have the following files (or a subset of it):

  • jdk-6u11-windows-i586-p.exe
  • jdk-6u11-windows-x64.exe
  • jre-6u11-windows-i586-p.exe
  • jre-6u11-windows-x64.exe

If you just deploy JRE, then you do not need to download the JDK packages. Similarly you do not need the x64 packages if you deploy to 32-bit OS only.

Prepare installation

Unfortunately the .exe installers do not always work silently when the "/v/qn..." switch is used. On 64-bit OS it might yield a "package not found" error in silent installation. That's why I recommend to pre-extract the packages.

  1. Run the installer as usual (e.g. double-click "jdk-6u10-windows-i586-p.exe"
  2. Get the extracted installer from "%AppData%\Sun\Java\" ("%LocalAppData%\..\LocalLow\Sun\Java" in Vista) and copy them to the package deployment folder. Do this for all packages you like to deploy. Here's a sample how my directory structure looks after extracting and copying:
    • JavaSE/install.cmd
    • JavaSE/jdk1.6.0_11_32/jdk-6u11-windows-i586-p.exe
    • JavaSE/jdk1.6.0_11_32/jdk1.6.0_11.msi
    • JavaSE/jdk1.6.0_11_32/sb160110.cab
    • JavaSE/jdk1.6.0_11_32/sd160110.cab
    • JavaSE/jdk1.6.0_11_32/sj160110.cab
    • JavaSE/jdk1.6.0_11_32/sp160110.cab
    • JavaSE/jdk1.6.0_11_32/sr160110.cab
    • JavaSE/jdk1.6.0_11_32/ss160110.cab
    • JavaSE/jdk1.6.0_11_32/st160110.cab
    • JavaSE/jdk1.6.0_11_32/sz160110.cab
    • JavaSE/jdk1.6.0_11_x64/jdk-6u11-windows-x64.exe
    • JavaSE/jdk1.6.0_11_x64/jdk-6u11-windows-x64.msi
      • Note: This installer seems to be different from all the others. It uses a different package format and extracts to "%TEMP%\<UID>". So you have to grab the MSI file from there.
    • JavaSE/jre1.6.0_11_32/Data1.cab
    • JavaSE/jre1.6.0_11_32/jre-6u11-windows-i586-p.exe
    • JavaSE/jre1.6.0_11_32/jre1.6.0_11.msi
    • JavaSE/jre1.6.0_11_x64/Data1.cab
    • JavaSE/jre1.6.0_11_x64/jre-6u11-windows-x64.exe
    • JavaSE/jre1.6.0_11_x64/jre.msi
      • Note: I had to rename the msi file from "jre1.6.0_10.msi" to "jre.msi" in order to install properly. Without this fix it failed with a message that it could not locate "jre.msi". Seems to be a bug within the msi package.
    • JavaSE/unattended-jdk-uninstall.cmd
    • JavaSE/unattended-jdk.cmd
    • JavaSE/unattended-jre-uninstall.cmd
    • JavaSE/unattended-jre.cmd

Please NOTE: There are some *.cmd scripts listed which I use as install scripts. The scripts are listed within the following chapters.

Package definition

<?xml version="1.0" encoding="utf-8" ?>
<packages>

<package id='JRE' name='Java runtime environment' revision='16010' priority='50' reboot='false' >

</packages>

As you can see the package just runs the unattended* cmd script which will make sure the right packages for the currently running operating system is executed.

NOTE: This package definition is for JRE installation. If you would like to deploy JDK, then just refer to unattended-jdk* scripts insted.

The scripts

As listed above there are some scripts required. And here they come...

NOTE: The unattended* scripts are basically identical for all versions - they just need to list the correct MSI file within the header (PKG32 and PKG64 variables).

unattended-jre.cmd / unattended-jre-uninstall.cmd (both files are identical, you might also link them on Unix/Linux level).

As you can see the script is mainly used to determine the correct installer for 32- or 64-bit operating system.

NOTE: I am installing 32-bit version on 64-bit OS as well. This assures that 32-bit browsers can run the Java plug-in too.

Due to the fact that lots of installers are using always the same silent switches I prepared a generic "install.cmd" script. So I can just pass the installer filename and the type of installer as parameters and I do not have to care about the switches each time. So here it comes:

That's it. This framework is quite easy to re-use for upgrades. The only thing you have to do is to download the Java Offline installers for the edition you like to deploy, then extract it, put the files to a sub-folder of the scripts (see directory structure outlined above) and then change the PKG32 and PKG64 paths on top of the scripts accordingly.

Java Uninstall Method

If you are just starting out with WPKG and want to be able to uninstall all versions of Java prior to your first package, you can use JavaRa (http://raproducts.org/javara.html) to silently uninstall all prior versions of the JRE.

There's also a scripting solution. It can also be used for other programs like Adobe Reader. 

@ECHO OFF
rem Find all programs installed on the computer
ECHO Finding all Java-installations...
FOR /f %%I IN ('REG QUERY HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall') DO ECHO %%I | FIND "{" > NUL && CALL :All-Installations %%I
ECHO Finished removing Java.
GOTO :EOF

:All-Installations
rem Filter out all but the Sun Installations
FOR /f "tokens=2*" %%T IN ('REG QUERY %1 /v Publisher 2^> NUL') DO ECHO Removing: %%U | FIND "Sun" > NUL && CALL :Sun-Installations %1
GOTO :EOF
:Sun-Installations
rem Filter out all but the Sun-Java Installations. Note the tilde + n, which drops all the subkeys from the path
FOR /f "tokens=2*" %%T IN ('REG QUERY %1 /v DisplayName 2^> NUL') DO ECHO Removing: %%U | FIND "Java" && CALL :Sun-Java-Installs %~n1
GOTO :EOF
:Sun-Java-Installs
rem Run uninstaller in unattended mode
START "" /WAIT "%WinDir%\SYSTEM32\msiexec.exe" /x%1 /qn
GOTO :EOF

Here's a JScript variant using the MSI ActiveX object. Execute it with cscript. Any JRE from 1.4.2 up to including 1.6u7 will be removed: 

var msi = new ActiveXObject("WindowsInstaller.Installer");
msi.UILevel = 2; // INSTALLUILEVEL_NONE
var products = msi.Products;
for (var i = 0; i < products.Count; ++i)
    if (products.Item(i).match(/^\{(?:7148F0A8-6813-11D6-A77B-00B0D0142|3248F0A8-6813-11D6-A77B-00B0D01[56])/))
        msi.ConfigureProduct(products.Item(i), 0, 2 /* INSTALLSTATE_ABSENT */);

And here is a VBS equivalent 

Set msi = CreateObject("WindowsInstaller.Installer")
Set re = new regexp 
Const msiInstallStateAbsent = 2

re.pattern="{(" & _
				"7148F0A8-6813-11D6-A77B-00B0D0142" & _
				"|3248F0A8-6813-11D6-A77B-00B0D01[56]" & _
				")}"

msi.UILevel = 2 

For Each msipackage In msi.Products
	info = msipackage & " = " & msi.ProductInfo(msipackage, "ProductName")
	WScript.Echo(Info)
Next

For Each msipackage In msi.Products
	if re.test(msipackage) Then
		WScript.Echo("Uninstalling " +msipackage)
		msi.ConfigureProduct msipackage, 0, msiInstallStateAbsent
	End If
Next
