Java Web Start does not start

Hi,
This is a quite simple question I suppose, but I can't figure out the solution.
When starting my application using Java Web Start 1.0.1_02 the JWS application handler does not show up. JWS does only show a splash picture, then it disappear after 10-15 seconds. No error is written in the Java console window.
No errors occurred when installing JWS and it seems to be correctly installed, and JRE 1.3 is installed. I have successfully used my JNLP file earlier when I had JWS installed. After re-installation JWS does not work.
What is the error?

The two most likely problems are java version in config files, and proxy settings in config files.
can you run javaws with no args and get up the application manager ?
if yes - look at settings in the preference panel of appman.
if no - look at javaws.cfg manually (in your users home directory/.javaws)
make sure the path to javaws.cfg.jre.0.path="xxx" points to a working javaws executable.
make sure the proxy settings: javaws.cfg.proxy.host and port are ok,

Java Web Start Application surprisedly does not start anymore based on new JRE1.7.0_45

Hi everyone,
we have to maintain a self-developed Java Application which is running based on JRE1.5.0_51 (x64). Our recent client machines have JRE1.7.0_40 (x64 too) installed in addition to the mentioned (and needed) JRE1.5.0_51 (x64).
Everything was fine up to the point where we tried to install the newest JRE1.7.0_45 (x64) as the new version for doing the web start magic. The result is that our application (which is/was unchanged!) does not launch anymore. The strange thing is that we do not get any StackTrace, Exception or something else like this.
The startup process simply hangs :-(
Nothing has changed (application itself, firewall, network settings, hardware) apart from the new JRE version. It's reproducible at will. If I install JRE1.7.0_40 (x64) the application starts, if I install JRE1.7.0_45 (x64) the application hangs.
I can say for sure, that in both cases (*_40 AND *_45) Web Start is able to do the synchronizing job and to launch the application base on the correct JRE1.5.0_51 (x64).
My guess is that in case of an installed JRE1.7.0_45 (x64), the application hangs when it tries to connect to the database (Oracle 11g) via JDBC.
I found a little hint in the Web Start Console. Therefore I had to switch the trace level of the console to 3 (which includes security, network and basic)
In case of an installed JRE1.7.0_40 (x64) - which leads to a running application - I will receive the following output:

These last "network:" log entries will never stop. This will lead to an infinite loop which results in a great memory leak. I have to kill the process via windows task manager in order to get rid of it.
Does someone out there has the same problem? Are there any new additional security issues which prevent my client to establish the database connection on port 1521?
Any other ideas?
Thanks in advance for any hint on this issue!
Regards,
Alex

Resolution: We still were not able to solve this issue! The only way to get out of this is to install the JRE1.5 as the x64 variant. In this case no switching from 64-bit to 32-bit is needed and everything is on track again.
But this is still strange and unexplainable :-(

HT5559 Java web start does not work

I have followed the instructions in this article, including the last step about web start, but it still does not work, neither applets or web start. When I try to launch a JWS application by double clicking it I get the dreaded warning dialog:
To open this Web Start application, you need to download the Java Runtime Environment.
Click “More Info…” to visit the website for the Java Runtime Environment.
I do have a JRE installed, 1.6, since I for compatibility reasons can't upgrade.
Trying to launch a web start application from the commandline looks like this:
$ javaws /tmp/airview.jnlp
Java Web Start splash screen process exiting ...
Can not find message file: No such file or directory
Regular Java-programs work fine.
$ java -version
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

Read this thread https://discussions.apple.com/thread/4789691?tstart=0
This fixed the issue for me:
sudo /usr/libexec/PlistBuddy -c "Delete :JavaWebComponentVersionMinimum" /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta. plist
In the comments to the linked article someone suggests to comment out the node in stead of deleting it. Probably safer (it's explained further down how to do that). Anyway I already spent to much time on this nonsense, deleted it and it worked, so I'm happy.

Why sun leader do not think about "Why Java Web Start not be used widely"

{color:#ff0000}Why sun leader do not think about "Why Java Web Start not be used widely"
{color}
Java Web Start was instruduced in jdk1.2, it's about ten years ago,But it's still not widely used--WHY?
it's not because the design, it's becasue the code--the garbage code-- even the last version not work in many user computers,
just not work suddendly -- noboday know reason--- if you do not believe, please google internet, many people suffered and suffering from web start!
It's incredible that a famous big company like sun can not resolve an deployment problen in ten years that some very small company can do good work in much more short time !!!
That' sun-- always say and design good things, then publish trouble and pain to their users. I really do not know what the sun's engineers are doing in so
many years! -- why they do not know deployment is so important than others -- if deployment work fine, then the wrong thing can be correct easy !
Sun, please do an famous big company -- give happy to user rather than pain !!! Please give us -- your users an stable and fast java web start to save us.
{color:#ff6600}(Note: I use java web start to depoly our application, then receive endless complains, not work, slow and so on. now, we has no way just to give it up--design ourself's deployment-- that's also done by many pained people---just google it){color}
Here is an desing suggestion:
Client-end should be simple and stable, should let the server-end do complex thing .(now sun do opposite thing, they make Client-end complex, but server simple) ---it's because that Client-end will take widely effect on user's computer. update a few server is much more easy then update a amount of clients!

Does Netscape Enterprise Server support Java Web Start?

Hi,
I working on this problem too. Could you send me about
your project's details ? (spec and config)
My email: [email protected]
Thank you.I've come to the conclusion that Java Web Start does not support hosting applications on password protected servers. It plain does not not work.
If anyone can get it to work, please let me know.
For me the JWS version based servlet is not a hosting option. I'm stuck with a dumb old IIS server. The only reason I'd want to use the version based servlet hosting is to work around the update bugs.
See my other recent postings.
I've posted a bug-report on the bugparade, but it will take three months before I should expect a reply.
At that point, they may dismiss the bug-reports as "intended features", in which case I do wish there was more options to "turn off" "features" in the JNLP file. ;-)
For now I've been my client has accepted "security by obscurity" for the beta version of the program I'm working on, i.e. I've put the program in a "secret" place and turned off password protection.

¿Does exist any tablet which runs java web start?

I want to buy a tablet pc, for example, Samsung Galaxy, Ipad... or similar, for me it's not important the brand.
¿do you know if exists any tablet which can run a java web start application?
My application is compiled with jdk 1.4 and starts by a simple .jnlp web file.

799037 wrote:
Thanks friend.
Then, ¿does anybody know a particular model of tablet pc that runs JVM (and therefore JWS)?Read what I say: you need a tablet which runs a normal Windows or Linux OS. You don't run the JVM, the JVM has implementations for specific operating systems. So that is your criteria: it must be able to run such an OS. Once you have that, you can install the Java runtime on it.
Generally that will be a laptop/netbook which can be transformed into a tablet by turning the screen. Check your favorite computer web shop for possibilities, there are a few. Not really a Java question anymore either.

Not getting application in Java Web Start

Hello Sir,
I wanted to run an application using Java Web Start. So, I created a jnlp file and i have mentioned the necessary jar files and the main class file. when I clicked on the jnlp file, the application is running in the Server using Java Web Start and its shortcuts are creates on the desktop and in the startmenu. I am able to run the application by clicking on the shortcut in the server. But I am unable to Download the application in the Java Web Start. It is not showing any Error Messages and the application is not running in the cleint machines.
The contents of the jnlp file is as follows.

"I am unable to Download the application in the Java Web Start"
If webstart in not actually downloading the jar - is the jar in the correct location?
Is the server named dev01 and the directory structure actually /Dummy/New?
Note: you do need to set up the mine type JNLP on your server,
In my case the location of the JNLP file and main jar file passport is in the following directory.
c:\Inetpub\WIMRoot\application
The additional jars are in
c:\Inetpub\WIMRoot\application
I hope this may give you some clue

Java Web Start not working with Proxy

I have Java Web Start program not listening to proxy settings. It tries to access localhost using our proxy settings, but with no user name or password. I'm wondering if Java Web Start has proxy settings somewhere. I'm not sure since when we disable the proxy settings the program works without issue. Any thoughts?
Thanks

For instance Safari uses those System Proxy settings, Firefox uses it's own!
So Java is using it's own, now we're waiting for an expert to drop in!

OpenGL not starting from java using java web start

Dear All,
I am a beginner in java2d, please excuse if what I am asking is not your standards. My problem is that I am using a swing application that is delivered to a client machine through the webstart. It is a medical Image viewer(usually DICOM images of size 10~15 MB) . I am using windows XP in my client machines. My graphics card is 'Intel(R) 82865G Graphics controller' and installed with the latesr driver from the intel web site. My current problems are:
1. I tried starting the opengl through the command line using the option java -Dsun.java2d.opengl=True MyApp. My application started however the verbose says opengl could not be started. The message is as follows:
Could not enable OpenGL pipeline for default config on screen 0
2. How can I start open gl when my application is run by java web start? How can I know that open gl has started? I tried giving System.setProperty("sun.java2d.opengl","True") in the main function of the program. I couldnt see any message regarding the opengl in the web start console.
Any help would be greatly appreciated,
Thanks in advance,
zeus

Im not sure but a lot of times corruption happens and hence its better you redo your scheduling.

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 opening code not app

For the past year I have had no problems opening up *.jnlp files with Java Web Start. Starting last week when clicking on any link to launch a Java app I get the code opening up in TextEdit.
For example when I click on 'Welcome to Web Start' on this page: http://developer.apple.com/java/javawebstart/ I see (just to start)
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://developer.apple.com/java/javawebstart/apps/welcome" href="JWS_Demo.jnlp">
<information>
<title>Welcome to Web Start!</title>
<vendor>Apple Computer, Inc.</vendor>
<homepage href="http://developer.apple.com/java/javawebstart" />
<offline-allowed />
Can anyone please point me to a way to repair my Web Start installation? I give a lot of webinars and they all require that Java work.

ISSUE
After the Java update, jnlp files are opened by TextEdit and not Java Web Start.
SOLUTION
1. Find the jnlp file on your machine
2. Get Info (Cmd+I)
3. Expand the “Open with” section
4. Select “Other”
5. Navigate to Macintosh HD/System/Library/CoreServices/Java Web Start
6. Check the “Always Open With” option
7. Click the “Add” button
8. Click the “Change All...” button

SAP Web Dispatcher does not start as windows service

Hi,
I have successfully installed and configured SAP Web Dispatcher. When I start the web dispatcher from command prompt, it works fine. I created a windows service for web dispatcher using the command
ntscmgr install sapwebdisp -b "c:\program files\sap\sapwebdisp\sapwebdisp.exe"
-p "service pf=sapwebdisp.pfl -cleanup -auto_restart"
The command successfully created sapwebdisp service. The service also starts fine, but web dispatcher does not get started.
Any ideas experts?

Hi,
Ok. Few suggestions.
1. Can you review the SAP note:
552286 Troubleshooting for the SAP Web Dispatcher
2. When you said: "web dispatcher does not get started ", what error you got ? Can you be more details here ?
3. Please check the trace file dev_webdisp" that generated in the work directory. If the log entries is not abvious, increase the trace level to 2 or 3, and reproduce and re-check the trace file.
4. What is the output of the command "sapwebdisp -v"
5. How about sapwebdisp.pfl ? Are those settings correct ?
Hope this helps.

Vincent

Can anyone help me what was the problem?
Thanks,
