Unable to launch java web start

We have already devloped an application based on java web start. Most of the client machines, we try to install java web start and run the developed app, it works fine. For one of the clients machine, we have an issue with java web start itself, it does not startup and bring up the application manager. When you start java web start, it shows up the splash screen 'java web start 1.0.1' after some time, it vanishes and does not bring up the application manager. I have installed java web start 1.0.1_01 (build 04) installed on Windows 2000 Professional, by default that has installed JRE 1.3.1_04 also.
We verified the system, all the files being existing under c:\program files\java web start dir. And the JRE is also installed fine.
Couple of times we uninstalled, rebooted and installed.
Infact, we have even verified the file types for html, htm, which was set to msoffice, and we have changed to internet explorer. For jnlp file type it was already set to javaws.exe.
Can you please let me know what could be the problem.

Nagarjuna Rao Chakka

There's nothing to stop you installing 1.4 or even 1.4.2, it's the jnlp file that specifies which runtime version gets used to run your application - web start can be used to happily switch runtimes like this. You'll just need to have 1.4 and 1.3 installed on each machine. It's a good idea to upgrade the web start client as the old 1.0 version doesn't work at all well with Windows XP, it's structure of storing all the files in c:\program files works against the security restrictions built into XP.
Incidentally the config file you were looking for in under c:\program files\javaws\javaws.cfg, but this is different in later versions.
Your problem is most likely being caused by web start not being able to find the Java runtime version it was installed with, the client may well have installed a newer (or older) version of 1.3 which has broken the configuration.. another reason to upgrade is the old versions are very fragile in this respect; 1.4.2 can find installed runtimes far more dynamically. Fixing the config file above should get things working again, otherwise delete the .javaws directory in the user profile and re-start web start.
1.4.2 is the best at finding runtimes, but is marred by problems with the integration dialogs, locale always reported as en_US and some strange new behaviour with classloaders and malfunctioning auto installers.. jws 1.2 that comes with jre 1.4.1_x is far more reliable.

Unable to launch Integeration Builder - Java Web Start - Unexpected Error

Hi there,
I am not able to launch the Integeration builder. The ESR has no problem and is working fine though.
Here is the exception :- com.sap.aii.ibdir.gui.appl.ApplicationImpl
I have tried below options already :
1. Cleared the java cache under - javaws -logviewer
2. Go into administration and inside Directory --> Java Web Start Administration clicked "Restore archives and generate new sign."
Strange part is some of my colleagues here doesnt have any issue while opening the Integeration Builder. In fact I dont have any such issue in QA and PROD environment. The issue is only in DEV environment. Please advice.
Anshul

Hello,
Usually restoring the archives will help resolve the issue.
If the issue is occurring for just yourself maybe you could check that you are using the correct java version. e.g. for for 7. 1 java version 5
Also please refresh the Java Web Start:
If it's a Windows terminal, select Start - Run - javaws to launch Java Web Start and then clear the cache. File -> preferences ->
advanced -> clear folder button
If you have later versions of Java and doing the
Start -> Run doesn't give you anything, then select Start - Run and type Control and hit Enter. Double-click Java in the list
that displays to view the more up-to-date Java Control Panel. In the General tab, select Settings from the Temporary Internet Files section. Click Delete Files to clear the cache and then log into the Integration Builder again (download will be longer as jars will be cached locally again).
If the problem still remains I would advise to check that the latest patches have been applied for XI_TOOL, and also the other components MESSAGING SAP-XIAFC SAP_XIAF SAP_XIESR SAP_XIGUI

Unable to Launch Integration Builder: Java Web Start problem

Hi,
I am unable to launch the integration builder. I am using JDK 1.4.2_05. The java Web Start gives the following error:
Unsigned application requesting unrestricted access to system
Unsigned resource: http://<XIHostName>:50000/rep/repository/aii_util_rb.jar
I have tried deleting the Java web start cache, and even reinstalling the JDK.
Can someone suggest a workaround this problem ?
thanks,
Manish

The Java Web Start cannot accept unsigned jars. If the jars are signed, it will ask in a dialog box if it should allow unrestricted access to this jar.
In my case, I upgraded XI SP0 to SP4, which included updating the Adapter Core, Adapter Framework, and the XI TOOLS to SP4.
On launching the Web start, it seemed that the jars were not getting signed. JWS cannot allow unsigned jars to the client.
These jars are maintained in:
\usr\sap\<SID>\SYS\global\xi\directory_server\javaws\directory
I am having problems with my XI upgrade to SP4, and it is probably not signing the jars.
Do you know why this may be happening ...
thanks,
Manish

It happens the same under Windows 7 and Linux -using openJRE and icedtea as substitution of Java Web Start-.
I'm behind a proxy. In my browser -Chrome, IE and FF- putted the info of the proxy and I can browse. Aldo tried to put the info in the Java "Network Settings". It did not work -the launching of the console-.
I installed the last Java Web Start in Windows 7 -Java7 Update5-. I disabled my anti-virus and firewall. Always the same result.
Could you help me please. I don't have idea of what is going on.
Greetings.
PD: I tested from other machines of the company and it works. So, I guess is my laptop. I exported the oracle certificates from those machine and imported them into mine.

Can not launch swing application from Java Web Start 1.6.0_37

Refresh an open web page on closing an applet launch from Java Web Start

Hi
I launch an aplication via Java Web Start from a link in a web page. I am looking to a solution to refresh my web page when I close my applet.
Thanks in advance to give me the solution or only to let me know if it's possible or not.

everything's possible. but this is not trivial. there is no direct connection between the html page that launched the app and the app. You can create an indirect connection by having the app notify a server process when it closes and having the page periodically polling the server for the app's status.

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.

New to Java Web Start technology - unable to start JWS

I am new to JWS, and started with sample programs given at JWS product page.
I compiled the files and created the .war file and copied that file into the DOCUMENTROOT of my Web server. Also I copied the .jnlp file into the same location. After that I created a .html file in the same location which provide a link to .jnlp file.
Now, when I launch the html file, and click on the link, JWS window should have been launched and the application should have been started. But, what I see is the contents of .jnlp file on the browser.
What might be the problem? Please let me know the solution...
I am using Apache Web Server on a Win 2000 system. Also I modified the mime.types file under web server to include the following line:

Override the launch of Java Web Start

How can we stop the auto launch of Java web start and prompt the user to enter the desired location to download the jars.
And then launch the jars from that location.
Is there any solution for this.
Please help me in this regard
Nandita

The whole idea of WebStart is to relieve the user of the burden of downloading binaries themselves. The whole point is, they just click a link on a web page, some magic happens, and their app starts up.
Your idea is a complete waste of time.

How to add scroll function in the applet launched by Java Web Start?

I have Java Web Start installed in order for the applet to launch.The applet size: width:700 height:1000
my compuer resolution:800*600
the applet launched by Java Web Start can only be seen partly,especially height.How to add scroll function in the applet launched by Java Web Start?
Thanks for help.
email:[email protected]

You can very easily add a JScrollPane manually between the Applet and your content. Perhaps it would be beter if javaws did this automatically. In the browser, an applet can be any size. In Java Web Start an applet is directly contained within a JFrame, so it cannot be smaller than the minimum size of a JFrame, or Larger than the max.

Launching an applet with java web start

Is there a way to launch an applet with java web start? That is, to have the java appelt run in a browser but get deployed with a jnlp-file and have all the benefits of java web start?

Launched thru Java web Start...?

Is there a way to find out whether my application is launched through Java Web Start or as a stand-alone application?
I have think of 2 round about ways -
- Getting the service names using javax.jnlp.ServiceManager.getServiceNames(), which returns null if launched as a standalone application.
- Getting the classloader name.
But, I am looking for one more concrete way of doing it, if any?

Akhil,
I was looking for a solution for this very problem and came across a FAQ in another thread that was helpful. See http://vamphq.com/jwsfaq.html and more specifically http://vamphq.com/jwsfaq.html#under

Unable to run my application using java web start

i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzle

Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

Java web start unable to auto download java 1.6.0_14

Hi,
My application runs on java 1.6.0_14 and i want clients to use either 1.6.0_14 or higher while running the application. In the JNLP file i have mentioned j2se version as 1.6.0_14+
If the client machine has a java version lesser than 1.6.0_14, Java web start is not automatically downloading the given version from sun auto download site.
Isn' t this version supported by Sun for auto download? If yes, how to get around this problem?

Thanks..
We do have a web page from which we access the jnlp and that web page has javascript to force download of a specific version of JRE. Once it downloads the application on client machine, it creates an icon on the desktop.
If the application and jnlp is changed on the server, we want clients to go through the icon on desktop and still get the version of jre mentioned in the updated jnlp rather than having them go through the web page again do download the new JRE required...
