Where does Jre Installs

Hello everybody !
Where or should I put it correctly how does the
Jre installs it self in windows enviroment ?
I guessed sun uses the folder Java as default and then make
some changes in the Windows Registry.
Is this folder always going to be java as default ? and
Will sun continue to use the same folders in the registry ?
Where can I get to know much about this ?
Thanks
bashiro

I'd suggest specifying why you want to know how to locate Sun's JRE on a Windows computer. Usually people want to know about the specific virtual machine their Java code is currently running on (or about to run on), and the techniques for detecting this have no relation to the ones you're asking for.

  • Where does the installer extract its files to

    When you run the installer for thunderbird it extracts a number of files and puts them somewhere, where does it put them?
    The machines I want to install thunderbird to can only run things from certain directories (which excludes the users home directory), as a sys admin I want to be able to install thunderbird, but I cant as it appears to extract files to some directory where we cant run applications from.
    Ideally I would like to be able to move the files to somewhere where they can be run (as changing the security policy will take weeks if I am lucky).

    I have no idea, but on the start menu type %tmp% in the search or run box and press enter. Windows explorer will open in that folder.

  • Where Does Yosemite Installer Hide? (aka missing disk space)

    I've been using a 400GB partition on an external drive for Time Machine backups for some time and it's had plenty of room to work with. I upgraded to Yosemite recently and all was well with the Time Machine backups.
    Yesterday I downloaded Yosemite again to install it on a second drive so that I would have a second bootable drive. Today I got notice that there was not enough space on my Time Machine backup drive. Suddenly the 400GB was not enough and my primary boot drive had swollen to 480GB. I don't know what it had been, but obviously there is now a lot more on it than there was.
    My assumption is that I have the Yosemite Installer and/or hidden installer files that didn't get cleaned up after the second installation. I can't find anything in hidden files or folders that I recognize as such but soemthing is eating up lots of disk space that I need to free.
    Where does the App Store stash downloads in case that's it?
    If I hold Option on a restart, I no longer have the Installer as an optional boot disk, but I do get three "Recovery-10"... disks. Possibly those are the problem, but I can't locate them either.
    Any ideas would be appreciated.

    Ok, I may have found a possible solution. I found this at stack exchange. It's not the best option and it requires a simple shell command, and will not be able to be used to restore from Time Machine, but for backing up one or more directory, at least in the short term, this will work. Here it is:
    There seems to be an issue with Yosemite renaming the computer local host by adding (#) after the computer name. There are other reports of this happening in a thread on MacRumors Forum and I believe a few people have blamed this as a cause of time machine backup failures. I've tried a few of the suggestions in the thread but so far none have worked. I've stopped using time machine for now and reverted to an old bash rsync script.
    A really simple solution is to open the terminal and type:
    rsync -avu ~/ /Volumes/backup_disk/backup_folder
    replacing 'backup_disk' with the name of your external hard drive and 'backup_folder' with the name of the backup folder i.e.: 'yosemite_backup'. The three flags -avu mean: archive (a) copy the home directory recursively into sub folders, verbose (v) print to the terminal window everything you are copying (feel free to leave this out) and update (u) will only overwrite files that are newer than the archived file (useful after the initial main backup). This solution isn't as hands off as time machine but at least it's a simple way to back up vital information in Documents and Pictures/Videos.
    Hope this helps!

  • Where does the installer put AIR 3.6?

    I have installed CS6 Flash Pro on my Mac Mountain Lion, and just upgraded the AIR 3.xxx
    Apparently it already had 3.5 installed, and upgraded that to 3.6
    However, the Adobe Flash directory contains a directory AIR3.2 - not 3.5 and no other. So where is the AIR3.5 and or 3.6 directories that were installed?
    Thganks

    As far as I know, Adobe Flash CS6 comes with AIR 3.2. Go to Help / Manage AIR SDK to see the paths of installed SDKs or install other versions (using the [+] button).

  • JNLP does not trigger JRE installation

    Hi
    I want to launch my application with a minimum version of jre(i.e. 1.6.0_10). If on the system there is no jre installed
    or jre installed on the system is older than 1.6.0_10, i want jnlp to trigger the installation of jre 1.6.0_25.
    I tried following jnlp tags in my jnlp file:
    <java version="1.6.0_10+" href="http://download.oracle.com/otn-pub/java/jdk/6u25-b06/jre-6u25-windows-i586.exe"/>
    <j2se version="1.6.0_10+" href="http://download.oracle.com/otn-pub/java/jdk/6u25-b06/jre-6u25-windows-i586.exe"/>
    None of the above tags trigger the installation of jre if on the system there is no jre installed
    or installed jre is older than 1.6.0_10.
    Any help would be great.
    Thanks in advance.

If user has any jre greater than 1.6.0_10 version application will use that jre. But if user does not have minimal jre version (i.e. 1.6.0_10) then i want to trigger jre installation and install the certified jre version for application(i.e. 1.6.0_25).
    2) Have you validated the JNLP file using JaNeLA?
    3) How is the link to the JNLP embedded in the web page?To me JNLP looks fine as it works fine if the system has atleast minimal jre version (i.e. 1.6.0_10), but fails to download jre 1.6.0_25 if it does not have 1.6.0_10 or any greater jre installed.
    The link "http://download.oracle.com/otn-pub/java/jdk/6u25-b06/jre-6u25-windows-i586.exe" is the download link for jre 1.6.0_25.

  • Copying msvcr71.dll from JRE installation

    Hi,
    When we started developing with Java 6, we found that the exe files we generated would fail because they could not find "msvcr71.dll". We know how to resolve that problem - the release notes for Java 6 say that we should include that dll in the same directory as the exe.
    http://java.sun.com/javase/6/webnotes/
    (under Windows notes)
    Does anyone know what the licensing issues are for this? The release notes for Java 6 only tell us to distribute the DLL, but they don't mention any license obligations on us for doing so, and the page that they link to on the MSDN contains no information about redistribution.
    We were hoping to copy the DLL that is included in the JRE installation into our own installation, but we aren't sure if this is legal.
    The only thing we've been able to find about this is a similar issue with Python distributions where because developers would be distributing a version of Python with their software, and that Python distribution was created with a licensed version of MS Visual C (where the DLL comes from), then it would be ok that they were "distributing" the dll with their own software.
    The text of that argument is at http://www.thescripts.com/forum/thread554311.html
    Does anyone know what the licensing situation is?
    Thanks

    If you have a license for Microsoft Visual C++ 2003 then it works

  • ZAC JRE installation location

    Where does the ZAC put the JRE when it is deployed with the bootstrap
    installer (i.e. when Load Own JRE is selected)? Sometimes I get it on
    the
    C:\ drive but on some NT computers I am getting it on the user's
    homedrive/homepath. But...on one user that had a non-C:\
    homedrive/homepath, ZAC still put the JRE on C:\!!
    How can I know FOR CERTAIN where on the client's machine the JRE will be
    installed. I need to know because my application is being subsequently
    launched from a batch file and I need to create the batch file (created
    at
    install time) with the correct path to the JRE.
    Also, the BEA documentation
    (http://www.weblogic.com/docs/admindocs/zac.html#jre) says "the user
    ultimately decides where the JRE shall be installed." How and when does
    the
    user get to decide the JRE installation directory? I know they can
    select
    the directory for the application, but the JRE doesn't end up in the
    same
    directory as the application.
    Finally, please create a newsgroup just for ZAC. There is certainly
    plenty
    of interest and issues to warrant its own newsgroup.

    I've had a similar experience. I think ZAC needs to be more flexible when it
    comes to customization such as installation directories for JRE.

  • Packaging JRE/plug-in with Mozilla & our app... is JRE installer required?

    We distribute a version of our application as a standalone implementation of our web application. We use an applet to act as a wrapper of our application server, proxying request/responses through JavaScript/applet instead of HTTP/servlet.
    Right now we package the installer for our standalone application so that it installs JRE 1.3.1_01 using the standard installer, then installs the application. When the user wants to run the application, he opens a HTML page in IE 5.5 or IE 6 referencing the applet. From here the application runs just like it runs in the server-based mode.
    The problem with this model is our dependency on the target system having the correct browser. I would like to package Mozilla and the JRE with the application, thus giving us more control over the installation.
    Ideally, I would like to have an installer that simply creates a directory with our application, a dedicated copy of Mozilla, and a dedicated copy the JRE. That way we could custom configure Mozilla to contain NP*.DLL in the bin/plugins directory, and have a custom policy file in the JRE. Does the JRE installer do anything 'special,' such as create registry entries that the plug-in must reference to run? Does anyone have similar experience with doing this?
    Thanks!

    I'm actually trying to do the same thing I've been wondering what the best way is to package the JRE in this case. Is there a way to install the JRE without using the installer and just copy the files where we need to put them? I am using Phoenix, a mozilla fork, that does not have the plugins folder updated with the proper java plugins when the JRE is installed, we have to manually copy the plugins that got installed into the Mozilla folder. Please let me know if you found anything.
    Thanx.

  • Using axbridge.dll without going through the JRE installation process

    I've searched the web and this forum for this specific problem, and have found related items, but nothing that quite answers the question.
    I have an application that uses the JRE's axbridge.dll to access a DLL created from a Java bean. I used the packager to create a DLL named MyBean.dll.
    When I go through the full JRE install, everything works great. That is to say, when I execute Sun's JRE installation program and go through the normal install process, I can access the bean through MyBean.dll without any problems.
    I am accessing MyBean.dll from a Visual Basic 6.0 application. Converting to VB .Net is NOT an option at this time. The VB app uses MyBean.dll for a critical part of the application.
    It is my understanding that it is not strictly necessary to go through the full JRE installation process. Simply deploying the JRE by copying its directory (and all subdirectories) to your application's directory structure should be sufficient. This would be HIGHLY desirable for my application. In fact, if I can't do this, it may be a show-stopper.
    When I install my application in this way (i.e, by simply copying the JRE instead of "installing" it) it doesn't work at all. I immediately get an error saying that the executable "has encountered a problem and needs to close. We are sorry for the inconvenience" and a dialog is displayed offering to send the problem information to Microsoft.
    The details indicate clearly that the problem occurs in the axbridge.dll, version 1.4.2.60.
    1. Any ideas on how to get the axbridge.dll to work without going through the full JRE install?
    2. Are there any alternatives to using the axbridge.dll to get my VB app to be able to use the Java? Remember, it is VB that must call the Java, NOT the other way around.
    3. Is JNI an alternative? If so, can I use JNI to get VB to use Java, or do I have to write the DLL's in C++?
    Any help you can give would be VERY MUCH appreciated.

    I'm also on a JRE installation problem with the bridge.

    This is confirmed with process explorer : excel is using "C:\Program Files\Java\jre1.5.0_05\lib\rt.jar" and not "C:\win32app\Specific\jre1.5.0_05\lib\rt.jar"
    In other word, the axbridge check for its installation location in the registry to know where to start.
    Even if all your components have been updated in the registry as suggested here : http://forum.java.sun.com/thread.jspa?forumID=40&threadID=559704
    JRE Bug or feature?
    Anyway the registry is evil.

  • Basic questions about JRE installation

    I am using NSIS to make a installer, which insalls the JRE 1.5, JMF, Javamp3, then our own software packages.....
    Firstly I have some basic question about the general installatio/deinstallation.
    1 Why sometimes is it required to reboot computer for the installed software to take effect, e.g.
    JRE 1.5. If not, what doest NOT take effect? (Actually in many cases, it seems to work even if not reboot the computer).
    Regarding the JRE 1.5,
    I am wondering:
    1 where is the registry entry written in windows?
    2 how to make the JRE installation process silent?
    Thanks !

  • Where does Bridge CS5 store the metadata files?

    Where does Bridge CS5 store the metadata files that are created under the Tools menu?  I moved CS5 from one drive to another on my Mac Pro and lost all of them.  I'd like to recover them is possible.

    Yikes!

    …I moved CS5 from one drive to another on my Mac Pro…
    First of all, all Adobe applications really need to be installed and reside permanently on your boot volume, i.e. the same volume where your OS resides.  There will be endless grief if you install the applications elsewhere.
    Secondly, I hope by "moved" you mean that you deactivated CS5 and then used the Adobe Uninstaller to uninstall CS5, then re-installed CS5 from the original media, from scratch, and not just drag-copied the Application folder.  And hopefully there's an OS installation on that other drive that will allow you to boot off that drive.
    Third, you need to refer to your preferences in Bridge as you set them to find out whether you were keeping the cache in distributed folders or were using the central database, whether you were using separate xmp sidecar files, whether you had Export Cache to Distributed Folders set in Bridge preferences, etc..
