Need to prevent JRE download in JNLP

I need to have the following scenario.
If JRE installed and correct value then go get the application JAR file and run.
If JRE NOT installed then DO NOT download (display a message, throw an exception)
(end user is not to install s/w on machine, but to get IT group involved)
Whenever I try and create this sittuation the JNLP always tries to download a JRE from Javasoft.
Thanks for your help

Disable JRE download

I have a customer that does not want to allow the user to download a JRE (even if the JRE is not on their machine). They just want to launch of our application to fail. Anyway to tell JWS (via properties or via the JNLP file) not to try to autodownload and install a JRE?
Thanks!
Rick

Configuration has a property in advanced tab in1.6 to disallow jre downloads:
also jnlp file could specify j2se tag twice. first with a dummy href:
<j2se version ="1.4.2*" href-"http://mycorp.com/no jre downloads allowed"/>
<j2se version="1.4.2*" href="http://java.sun.com/products/ah\utodl/j2se"/>
this way, if suns version 1.4.2 was there program would run, else it would try to download the first one from -"http://mycorp.com/no jre downloads allowed" and get an error.
/Andy
PS - in 1.6 there is a control panel option for autodownload, user can slecet to always download, never download, or to be prompted before downloading jre.

How to specify a JRE range in jnlp file?

We have a java app which uses Java Web Start. The jnlp file is configured with [j2se version="1.5+"]. So if JRE 1.5 and 1.6 are installed, the app is run on 1.6.
Now, we have requirement where the app should be restricted to run only within the range - JRE 1.5.0_07 through JRE 1.5.0_17
[j2se version="1.5*"] will not work - it will always launch the app with the latest jre from 1.5 family.
I can request an exact product version by including the href attribute. [j2se version="1.5.0_14" href="http://java.sun.com/products/autodl/j2se"/]
But how do I specify a specific range of JREs in the jnlp file so that JWS picks up a JRE from that range only? So if 1.5.0_07, 1.5.0_17 and JRE 6 are installed, it should run the app on 1.5.0_17.
Can JNLP really allow you to select specific range of JREs? Is there a good way to accomplish this? Please help.

*4.6 Java Runtime Environment*
Several JREs can be specified, which indicates a prioritized list of the supported JREs, with the most preferred version first. For example,
    <java version="1.3" initial-heap-size="64m"/>
    <java version="1.2">
      <resources> ... </resources>
    </java>So your app. would need more along the lines of..
    <java version="1.5.0_07 1.5.0_08 1.5.0_09 1.5.0_10 1.5.0_11 1.5.0_12 1.5.0_07 1.5.0_13 1.5.0_14 1.5.0_15 1.5.0_16 1.5.0_17 " />
    <java version="1.6+" />Actually you'd need the list of 1.5 versions reversed. Well, you get the idea hopefully. For more on versioning, see my [JWS versioning page|http://pscode.org/jws/version.html].

JDK/JRE Download Page has Wrong File

Hello,
On the JDK and JRE download pages, the download for Windows Itanium (IA64) actually contains the AMD64 (x64, x86_64) download, even though the file itself is labeled as IA64. Where can I download the Windows Itanium JDK (or even JRE at this point--I just need Java)? And who can I get in touch with to have this issue rectified?
Thanks,
Nick

Intel and Amd's implementations of x64 are basically the same. It's just Intel's Itanium architecture that's radically different. Originally it was supposed to be the replacement for x86, but it ended up in a niche server market. My point is is that the two architectures require differently compiled binaries. Java.com doesn't even list the IA64 binaries as most home users wouldn't have their own Itanium server. That's why you have to come to the Oracle page to get it. The IA64 download says it is meant for the Itanium processor so that only those with Itanium machines will download it. My issue is that the person at Oracle who posted the download doesn't know the difference and is posting the two as if they're interchangeable. While most users won't notice the difference, the few who actually need the Itanium binaries will.

Link to JRE download page

Link to JRE download page
I maintain a free Java program which can be started from the Web-site.
On the Web-site I need to tell how Java is downloaded and installed.
What download page should I link to ?
I found only http://java.sun.com/javase/downloads/index.jsp.
However, this seems to be a download page for developers and JRE is described among
other technologies and programming tools.
I guess there is somewhere a download page for end-users but I
did not find it even with the site map.

http://java.com is intended for end users.
Note that this site does not necessarily feature the most up-to-date Java version (right now, the version being served up is 1.5.0_09, as opposed to the most current 1.6.0.) Clicking "Manual Update" then "Download other Java software versions " leads to instructions for them.

JRE Download without Installation

Hy guys,
Its me again with a beginner Question i dont even need to search if we had that yet.
I feel like the only stupid one that has this problem...
WHERE CAN I DOWNLOAD A NO-INSTALL JRE?
I mean i can find a hundred million links to jre installation (e.g. .exe) files, but none i can just download and
have like this folder structure:
- jre1.6.0_15
- bin
- lib
- Changes (File)
- Copyright (File)
You know what i mean? I am a developper since 5 years and waste my time with such things:(
(I waste about 2 hours with any new JRE Release just because i cant install something on my working machine..)
Thank you very much for any helpful link (I mean it seems that i realy dont understand something about this JREs...) .
Regards
Balsi

so i wanted to find out how about a no-install distribution.
Just install it so its done properly.. They provide a ntebeans kit and a everything u need in 1 conveniant download for a reason. I did this today and took me 5 mins!
=> Yeah, exactly what i didnt want to have.
But after this i still need to say:
"Your post is worthless"

P.s. dont be mad with me, i just have enoth of these "i repeat what everyone else said and make it look like the one who asked is stupid", it took me 5 mins now (well i cant acctually do anything anyways...) to write this... even if its as senceless as your post, i know youre reading it;)
Have a nice day!This morning Balsi went to work and wanted Java on the company PC.....
This morning Yucca wanted Java on his laptop.
Balsi did not spend 5 mins to google as he feels to important to use this search function and chose to do a post where he sounded uniterested with comments like "waster of my time"
Yucca googled Java JDK download and has everything he needs for tomorrow.
Balsi does not.
My post was nort worthless it showed how 5 mins can get you way ahead if you just make the effort.

Need to install JRE 1.1.8 as Netscape-Plugin

Hi,
I need to install JRE 1.1.8 as an plugin for Netscape 4.75/78.
Downloaded and installed JRE 1.1.8 from javasoft, but the
JRE is not listed in Netscape plugin-list.
How to register JRE 1.1 as an plugin ?
Thanks in advance.

Hi ,
After installing the plug-in check in the Netscape browser Help(option)-->About Plug-in's whether 1.1 version is there or not. If it is there then I think it will support.

How can I disable itunes on my iphone 4s? I don't use it for music and need to prevent it from automatically activating when I plug in to my vehicle.

How do I disable itunes on my iphone 4s? I don't use the phone for music, and I need to prevent it from automaically playing music when I plug the phone into my vehicle. I have attempted to delete all music from the device (so there would be nothing to play), but 1 song remains in the iphone memory and I have been unable to delete that song.

iTunes app on the iPhone is for purchasing music.
The fact the iPhone starts playing when connected to your car stereo is a function of your car bluetooth system.
Consult your car dealer/bluetooth system manual.
I have attempted to delete all music from the device (so there would be nothing to play), but 1 song remains in the iphone memory and I have been unable to delete that song.
Connect the iPhone to computer and select it in iTunes.
Click the Music tab and uncheck Sync music.
Then click Apply at lower right of iTunes.

I need help! i downloaded new music and plugged my iphone into my computer and after i did that i lost all my pictures and everything that i need!!! it restored my iphone back to setting from february of last year when i last had an iphone, HELP! PLEASE!

I need some help fast please!! i have had the iphone since august and have videos and pictures i need like 100% need, and today i downloaded music and plugged my phone into my computer. The phone synched and it did to the settings when the iphone 4 first came out last year, dating back to when i first had it on february 24th, 2011. I need to restore it back but everytime i try to do it through itunes it puts me back to the same settings, i hope someone knows how to fix this problem, i would greatly appreciate any help!!!!

Check here and see if you got an automatic backup when you pluuged into iTunes. (Fingers Crossed)
Documents and Settings\USERNAME\Application Data\Apple Computer\MobileSync\Backup
If the recent backup is there, simply restore your phone from that backup. It sounds to me that instead of syncing the phone just by connecting it to the computer, you may have restored the phone to your ancient backup. No problem if you have the newer backup, but a huge problem if you don't have the recent backup.
If, in fact, you did restore the phone instead of getting a backup thru the (automatic) sync process, I'd strongly suggest getting the difference between the two straight in your mind.
My other suggestion would be to understand that your iPhone is "managed" thru iTunes. You need to connect the two whenever possible instead of using the charger.

I have tried downloading photoshop cs2 and cs4 on a new computer. I have the disc available for cs2 and the serial number for cs4. They are both registered in my name. I need help doing a download.

I have tried downloading photoshop cs2 and cs4 on a new computer. I have the disc available for cs2 and the serial number for cs4. They are both registered in my name. I need help doing a download. I was able to get part way through cs4, it showed up in my downloads but never got as far in the process as to ask for serial numbers. I tried with cs2 and I got an error message that some bit of information was incorrect. I currently have both downloaded on two other lap tops I own. One is operational and one is dead. I cannot access the dead one to remove the program. Thank you in advance for any assistance.

For CS2 you will need to download a special new version

Need some help with downloading PDF's from the net.

need some help with downloading PDF's from the net. Each time I try to click on a link from a website, if it takes me to a new screen to view a pdf, it just comes up as a blank black screen? any suggestions?

Back up all data.
Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.
