Web Start use always the newest version instead version in jnlp

Hello,
I have the following problem:
Problem is a JRE is installed on client but this jre shouldn't used. A jnlp file is started with a local copied jre and the javaws.exe. When the installed version is newer than copied jre then this jre is used to executed the jnlp. Is the installed jre is lower than copied jre than the copied version is used to execute.
The jnlp file contains the version with udpate '1.6.0_11' which should used (this is the copied jre) but when a newer version is installed than the javaws try to download the version but not used the copied jre.
I want that a copied jre is use to launch an application not the local installed version. A new JRE needs an approval from the producer of the application. For launching the jnlp a tool copied the jre to the client.
Is there any solution for this?
Regards,
Christoph

As far as I understand from (my) document on JRE versioning that should work to specify the [micro-version|http://pscode.org/jws/version.html#micro].
I suggest you validate the JNLP using JaNeLA. If it reports no errors, search the [bug database|http://bugs.sun.com/], and if you can find no similar bug, report one.

Re-installing the Firefox browser is fairly easy. For most users the important part is the information held in the [[profiles|profile]] including bookmarks and passwords.
If you remove personal settings it is almost impossible to get them back. You can however [[what is firefox sync?|sync]] between computers, and that effectively clones your bookmarks etc.
If you have not already removed setting do not do so now, some of that info may be recoverable.

Web start fires up the installer twice

All
We are seeing some issues where java web start is invoking the installer twice for some reason instead of once.
When we install the application using the installer it installs correctly and everything looks good .But whenever the user clicks on the shortcut icon it tries to install the application again by downloading all the jar files and gets the installer screen again .This happens twice but im not sure why.
I tried this on two JRE .14 and .15 and both had same problems.
Im pasting the two JNLP files we are using . The first JNLP is the main jnlp file which refers to the installer jnlp using the extension tag.

I'm not sure why the installer was getting fired twice .
To solve this problem i tried to update      <shortcut> tag to have a online attribute <shortcut online="false">
By doing this it prevented the installer from firing up twice but it alerts the user with another alert which tells "The application has requested to go online ".
Can someone let me know why this would happen.
Also let me know if there is a way to have java web start application always launch offline and check for updates?
Thanks
Chetan

In this very same forum BenGlacy said he got there (no online launch and check for update) by removing the jnlp href attribute.
Anyway there's something that doen't make sense in your post

If your installer does anything different, that could be the reason of your problems. By the way, in Java Web Start you don't install (period), you launch.
If you, instead, mean the javaws -install option, please check all hrefs in JNLPs and look for 'twin' entries in your cache (javaws -viewer), resources are chached by URL, even the slightest difference can make them appear like 2 different voices.
Application tries to go online 'cause it has an absolute href (instead of one relative to the codebase), althought, I gotta say, you may find in this forum that absolute href happened sometime to solve some problems. About this, why are you using absolute path (repeating codebase) on every resource (afaik, this never solved any probleam)?

Java 7 Web start fails to download Java 1.6 version

Sorry for the almost exact duplication of a previous thread, but that was closed (Java 7 Web start fails to download Java 1.6 version
When launching an application requiring Java 1.6 with a Java 1.7 web start it fails when it tries to download 1.6 with the following message:
"Unable to download http://javadl-esd.sun.com/update/1.6.0/1.6.0_29-b11.xml for installation"
Problem only seems to occur on Windows 7 (64 bit), seems fine on Windows XP.
Bug has been raised with Oracle by poster Matt Taylor - http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7168311
Does anybody have any ideas?
Thanks,

When it does not work do you use Deployment Toolkit to embed link into web page?

Web Start Security and the Cache

Hi,
If the jars are signed and download occurs then webstart will verify the signature and tell the user that jars signed by user xxxxx are about to be run. Then the jars are cached by web start. My question is, what is to stop an attacker from replacing the jars in the cache with malicious ones? Does web start verify the signature on the jars when they are loaded from the cache aswell, thus preventing the jars from being changed? Or does the versioning system web start uses somehow prevent replacing the jars.
Thanks for any help,
Dave.

How would an attacker replace the jars with malicious ones? Through the initial signed jars? That means the initial ones are already malicious anyway, so why bother? After all, the user has already given those signed jars all-permissions anyway...
I'm sure you could devise some other means to do it using virus-like software, but all this would give you far greater control over the users machine than anything those cached jars could ever give you, even if the JNLP client did no checking on its cache whatsoever.

Your jnlp checker Vanessa is quite useful.
Is the source available, because I would like to fix a bug or two I noticed.
Then check out Gentleware's Poseidon.
http://www.gentleware.com/download/Poseidon4umlJWS.jnlp
It is a commercial version of Tigris.org's ArgoUML, a free UML editor,
which is webstartable as well:
http://argouml.tigris.org/files/documents/4/0/0100/ArgoUMLWebStart.jnlp
Interesting about Poseidon was how they implemented key registration for their JWS app, a common task for commercial applications.
However Poseidon unwillingly illustrates limitations of the present JWS implementation - this beast is large (about 10-30 MB).
I loaded it at home via an ISDN link (8KB/s) and it took much time. The download was interrupted for several times, I hadn't start to download again from zero, because the app is splitted into several smaller jars, but still had to reload interrupted jars.
Some days later it turned out that the disk I had the JWS cache on got full. Thus I wanted to move my precious downloads to another partition, which is not possible. You can't move cache contents elsewere, so I had to redownload it again later (ouch).
An interesting bit about ArgoUML is how they speed up their large app by forcing class loading in a background thread. I saw that in their source and want to try out that technique myself soon, perhaps it gives a little speed advantage.

Does the NVIDIA GeForce GTX Titan X work with the newest AE CC version?

Hello
I would like to know if I can use the GeForce GTX Titan X for the newest AE CC version? On the system requirements Page (2014) for ray-traced 3D renderer, the GTX Titan is mentioned, but not the Titan X. Is the Titan X also working? Who can help me.
I would like to run it on a HP z640 (Windows) Computer.
THX for all the help.
Tom

Sorry for my earlier typo. I meant the Porsche 918 Spyder.
To determine when to use the Titan X, use a rough rule of thumb like this formula:
MIN (N, 1.5) x (physical cores/CPU) x (clock speed), where N is the number of CPU's.
Your example with dual E5-2643v3 results in: 1.5 x 6 x 3.4 = 30.6
With dual E5-2697v3, the result is: 1.5 x 14 x 2.6 = 54.6
WIth a single i7-5960, overclocked to 4.5, the result is: 1 x 8 x 4.5 = 36
When the result is < 40, it is highly doubtful the Titan X can be used to full potential, when the result is between 40 - 50, it may occasionally be used to full potential, when the result is > 50, it is very likely to be a very good choice.
This statement assumes that memory is at least 64 GB and the disk setup is very fast on all volumes with transfer rates in excess of 800 MB/s.

Restart your Mac and immediately hold down the Shift key when you hear the startup chime to boot into Safe Mode. Keep holding the Shift key until you see a progress bar towards the bottom of the screen. You can let go of the Shift key at that point.
OS X asks you to log in (you will get this screen on a Safe Mode boot even if your Mac is set to automatically log in). Let the Mac finish booting to the desktop and then restart normally. This will clear Font Book's database and the cache files of the user account you logged into in Safe Mode.
Next, close all running applications. From an administrator account, open the Terminal app and enter the following command. You can also copy/paste it from here into the Terminal window:
sudo atsutil databases -remove
Terminal will then ask for your admin password. As you type, it will not show anything, so be sure to enter it correctly.
This removes all font cache files. Both for the system and the current user font cache files. After running the command, close Terminal and immediately restart your Mac.

When Java Web Start starts up, it tries to determine the Proxy Settings from either the users deployment.properties file, or from the browser (if the deployment.properties setting is set to the default "Use Browser Settings"
In either case the setting can be to use an automatic proxy configuration script. If it is, Java Web Start will invoke the MS java script engine to parse the config script.
This sounds like an error message from there.
To fix this, you could use the Java Control Panel to set the proxy directly, or change the setting in the browser.
In versions before 1.5.0, Java Web Start would always go to the IE system settings for proxy. In JDK 6, javaWeb Start will read the proxy settings from the "default browser". If this is Firefox, it may return different settings than are set in IE (the default system proxy settings).

Mac OSX 10.6.2 Java 6 Web Start not always version checking on launch

When launching a Swing app via Web Start on Snow Leopard, it will often fail to discover and download the new version. This feature works consistently with Java 6 on Linux and Windows PC's.
The web-start app is accessed using an Application Bundle created with the Java Preferences app. If I clear the cache in Java Preferences, Web Start will nicely download the application and run it. However, after deploying a new version of the app, the Mac client will often run the cached version of the app without downloading the new version. Is anyone else experiencing this problem?

Re: "Alternatively, if you don't want to do this, the only other option I am aware of to solve this problem is to buy software like Fusion or Parallels and install Leopard (10.5) as your OS and run MX 2004 within a virtual environment."
Just so this is perfectly clear..... NO CAN DO
I have VMWare and Parallels on a Brand New MacBook Pro. It came with 10.5.11 and that is absolutely the OLDEST Mac OS I can install in a virtual environment. Believe me, I tried Tiger, Panther and Jaguar to no avail.
If the Mac in question came loaded with Snow Leopard, it has a "Snow Leopard or better" firmware write on the logic board and it will not allow an older OS to be installed.... even in a virtual environment, unless there's a secret that nobody I've spoken to in support for both VM clients knows.

My online classes require that I use 3.6 (because the newest 9.0 version is changing my answers) ... How do I reinstall Mozilla 3.6 on my computer ?? Please help me!

I have updated to the newest version, but my online school is not compatible with the newest version. I need to go back to the 3.6 version. Can you please assist me with changing this for me so I can do my work ??

To downgrade to Firefox '''3.6.25''' ('''that is the only one supported except latest 9.0.x'''), download and run its installer from:
http://www.mozilla.org/en-US/firefox/all-older.html
