Java Web Start doesn't start

I have installed Java 7 update 51 in Mac OS X 10.7.5. Yesterday Java Web Start starts well but today doesn't start. /Library/Application Support/Oracle/Java/javaws displays this error:
Bad Installation: JAVAWS_HOME not set.

Hi,
I found some stuff, but it didn't work for me. Maybe you can give it a try.
1. Deactivate Proxy
Add or edit javaws.cfg.proxy.setting=NONE in the javaws.cfg file.
2. Deactivate Splashscreen
Add option "-Xnosplash" in the Windows registry for the .JNLP ending, i.e. "C:\Program Files\Java Web Start\javaws.exe" "-Xnosplash" "%1"
3. Run with Java VM
I created a .BAT file:
SET JWS=C:/Programme/Java Web Start
java -cp "%JWS%/javaws.jar" "-Djnlpx.home=%JWS%" com.sun.javaws.Main %1
To run Java Web Start simply run the .BAT file. To run a specific application run the .BAT file with the complete URL of the .JNLP file.
If this works for you, please drop a note here! Thanks!

Java Web Start doesn't start (Windows XP)

Hi,
I've installed Java Web Start on a Windows XP machine. When I try to run an application or I try to open Java Web Start directly the "Java Web Start" splash screen appears for a few seconds and than disappears and nothing else happens.
I heard that other people using Windows XP have the same problem. Can anyone help?
Java Runtime is 1.4.0, but I also tried some other runtimes as well with the same result.
Thanks in advance

Personal Web Sharing doesn't start up

A while ago I shut off the "Personal Web Sharing" tool simply because I did not need it. However at this moment I'm trying to restart it (which I assume is the Apache web service). So I go to System Preferences -> Sharing, and tick the "Personal Web Sharing" box. However, when I do, all I get is the message "Web sharing is starting up..." It stalls there and doesn't go any further.
I haven't made any changes to Apache, but I have attempted to install PHP on my system using the package on http://www.entropy.ch/software/macosx/ -- it failed, giving me a generic error message.
Is there a solution to this problem? Does it have anything to do with the messed-up PHP installation?

I am experiencing the same problem: going through the System Preferences (in OSX 10.4.10), to the Sharing pane, then the Services Tab, and clicking Start Personal Web Sharing only gives me "Starting Web Sharing..." and never actually starts it.
I have tried the following solutions:
• replaced httpd.conf files using both the httpd.conf.default file from the machine in error as well as from another Mac (adapting the usernames as appropriate)
• replacing the entire /private/etc/httpd directory with the one from the other Mac, whose Web Server will start up
• when starting it via Terminal, i get "fopen: no such file or directory" so I created it... no dice.
Can anybody give me any more suggestions?
If not, I do have AppleCare on it - think they might help?

WEB server doesn't start after php5 install failed

Hi,
Running a PPC G4 with osx server 10.3.9
I tried to install entropy php 5.1.6 on my server but it failed and said it could not complete the install.
After that my web service stopped and I can't turn it on anymore.
Please HELP !
I can't reinstall the whole OS because I need ton keep my MySQL DB.
When doing [sudo apachectl start]
I get the error :
dyld: /usr/sbin/httpd Undefined symbols:
_untitled
/usr/sbin/apachectl: line 193: 850 Trace/BPT trap $HTTPD
/usr/sbin/apachectl start: httpd could not be started
Thanks

Just found the answer on Entropy
php5.1.6 from entropy is for 10.4 only apparently
Someone just gave me 5.1.2 and it worked fine after I completely reinstalled my Server...
So remember OSX Server 10.3.9 loves 5.1.2 php package from entropy,
Just install the package of php5 as your php4 module is off and the web service stopped
Then add the module of php5 in your list
Finally turn on web service and ENJOY !

Java Web Start(the program itself) doesn't start in offline mode

Hi,
My Java Web Start doesn't start when my internet connection is not on??? I have a program that needs also offline access so it's crucial to get JWS work without internet connection as well.
The problem might be in those sun's example programs you can't remove? Maybe the program crashes when trying to get some information for those programs?
(please read the question well. My problem IS NOT in the .jnlp-files <offline-allowed/>)
And by the way those sun's demo programs that are supposed to start in offline mode(Internet connection not required) don't start even if you have started them once with the connection on.....
-orainio

I have the SAME problem -
BUT....
it NEVER works for me (online & offline)
this stupid logon pops up and after a while disappears and nothing happens!
got no fire wall, proxy etc...
(win XP)
plz helppppppppp

Web Start doesn't run after install

Hi all,
I'm wondering wether Web Start doesn't start after successful installation. Only the splash screen is shown a while when starting JWS and the administration screen doesn't pop up.
I've read some mails about similiar problems (proxy?), but didn't resolve the problem yet.
NT 4.0 SP 5, JWS 1.01._01 with RT
also tried: JSDK 1.4 beta3 with JWS included
please help. thank you
regards, thomas

Hello,
I am not sure, but this does sound like I had the same problem. I got the following reply:
Take a look at:
http://www.geocities.com/vamp201/jwsfaq.html
--> 'Why can't I start Web Start's app manager under Windows? Why does the app manager's preferences dialog fail to appear? '
This might be a proxy issue. Try to turn off your proxy by putting
javaws.cfg.proxy.setting=NONE
in your 'javaws.cfg' file and see if it Web Start's app manager shows up then.
I have added the line mentioned above, and it worked fine. In addition I added the following line:
javaws.cfg.jre.default=0
Check this out and good luck!

Application started using Java Web Start doesn't launch the first time

I have a Facebook photo uploader application that I plan to distribute using Java Web Start. I'm using Java 6u4 on Windows XP SP2 with 2GB of RAM. I have Java 6u3, Java 6u4 and Java 5 u14 installed and I'm sure the one used is Java 6u4.
I signed my application and make use of all security settings.

The first time the application is installed using a link on the browser it's downloaded then the certificate dialog is shown, after that I check the checkbox to accept the certificate permanently. The application doesn't load, it only loads the second time although I see it in the task manager. If I don't accept the certificate permanently it does load. This happens on both Firefox 2 and IE 7. I enabled the console and logging but nothing shows up there.That's really a weird problem, I wonder if Java Web Start is a viable deployment option, it does have great capabilities such as autoupdate but still seems to have important bugs.
Does anyone have any clue about what is going on.
The problem doesn't occur on Ubuntu 7.10.

You were right my XML file was not correct. I still couldn't find a valid JNLP validator. Sun has to provide that.>No they don't (have to supply a validator for their own document type, though it makes sense to do so), but yes they do (provide a tool that validates XML against schemas). Java can validate XML against a DTD or XSD.
Check these two threads (and chase the links) for more details.
JNLP xsd schema
<http://groups.google.com.au/group/comp.lang.java.programmer/browse_thread/thread/c6f65bf1df5f105d/30c6b7e2dc342dc4>
Validate XML against DTD? XSD OK. SSCCE.
<http://groups.google.com.au/group/comp.lang.java.programmer/browse_thread/thread/5b997a1edb765b11/e831f3066eb4aa38>
Look especially for the posts by Piotr Kobzda.
I had a tool on my site based largely on Piotr's codes, that linked to a valid JNLP DTD and XSD, but unfortunately my site is offline at the moment. Andy assures me that the JNLP 6.0 DTD has been corrected for the developer ..download tutorials of web start, though the online (web site) version may still be invalid.

Why Java Web Start doesn't support Pack200 out-of-the-box?

Hello All,
Why Java Web Start doesn't support Pack200 out-of-the-box? I was hoping that Java 6 would make things easier by adding direct support for Pack200 in Java Web Start and JNLP without needing to use servlets, etc.? All my clients are Java 5 or above so I can't push the Pack200 compressed version of the jar to every single one of them and there is no selection process needed. But I can't do it because of the servlet or complex Apache server setup requirement (it would be a headache to get customers' web server admins to set up Apache or whatever web server that way).
My question is why is there unwillingness to add Pack200 support directly to Java Web Start and JNLP so that you can start Pack200 compressed jars just like you would start any jar using Java Web Start? Is te a technical problem?
Thank you,
Mete Kural

Hallo,
I didn�t try it, but the webstart FAQ�s read:
Can I use Pack200 compression with the JnlpDownloadServlet?
Yes. The JnlpDownloadServlet distributed in the samples directory of the JDK now supports Pack200. If you deploy yourfile.jar along with yourfile.jar.pack.gz the packed file will be downloaded when the client is running Java Web Start 1.5.0 or later.
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/faq.html#217
For further information you may want to look at
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/downloadservletguide.html#pack200
The configuration of the server and the the servlet (as described in the second link) is as easy as it seems.
I got it working on the first try and it was my first experience with websevers at all.

Your answer isn't correct.
The problem is the locale setting.
Try

I did checked the names again and I found that the makeJar.bat had an "issue".
It missed the del *.jar and I had 2 uppercase letters like ConvertorValutar, instead of convertorvalutar.jar.
After that I rebuild the war and deployed and it works :)

Java console doesn't launch when starting Java Web Start app from Firefox

Updated my Linux desktop from RHEL to Fedora 12 with resultant upgrade of Firefox to 3.5.9 and now when I launch our Java Web Start application, no Java console appears. The Java Control Panel still shows "Show Console" as set. My app uses Java 1.5 which I have installed on my desktop.
What do I do to properly configure my browser/desktop to support use of the Java console?
Please help, I need to debug our app!

..Please help, I need to debug our app!Cannot tell you the answer to your FF hassles (because I have no idea why you're seeing that behaviour(1)), but note that you might be able side-step FF by launching a JWS app. using the javaws tool directly from the command line or an Ant build file.
1) Though you might try rebooting the machine if any installation/configuration changes have occurred since last boot.
Also note that many problems with JWS apps. can be sorted be checking the JNLP using JaNeLA.

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

First Java Web Start download doesn't update, second time does

I'm using Java Web Start with our application. This release we upgraded to java 1.5 from 1.4. Now I have a few PCs, not all, that do not get updates the first time they launch the application. But when the launch it the second time they get the download. The jnlp didn't change between releases? Any suggestions? I'm not using lazy loads, in fact I'm using the default which should be eager.
Thanks.

Hi,
I have similar situation. At the machine is installed Java 1.6 u1. Setup first version of application. After deploy second version of application and run application start update, but console show that application use old packages. At the same time main package is uploaded? I'd try to use <update check="always"?> but there are no positive result.
At the same time then installed Java 1.6 u2, all works fine.
Any suggestion, how it could be resolved, without Java 1.6 u2 installation?
Thans, Kirll.

Java Web Start doesn't run by clicking on the link, how can I fix it?

Hello,
I've been trying to make a Java Web Start application, I finished everything, but when I click on the link which is connected to the jnlp file, it only displays the XML code in the explorer instead of running the program. But if i download the jnlp file and double click it, it starts the Java Web Start. Anyone can tell me how to fix this?
I thought may be JRE installation, but I tried to click on some sample on the web, it works fine for other Java Web Start application, but not mine.
Thanks you.
Kit

Does your webserver know about JNLP? You need to map the .jnlp extension to "application/x-java-jnlp-file".
See the Web Server Setup section of http://java.sun.com/developer/technicalArticles/Programming/jnlp/
