Java web start in Windows vista

Hi,
1)
When i tried to launch my Java Web start application in Windows Vista (32bit) With Jre 1.6_06 the java web start did not loaded. the process terminates at certain points.
By Remote debugging got to know,: It was exiting the application at different points at different time
At some points it says ClassNotFoundException. No logs at cache location also.
Is it due to the jars are not loaded properly?? Jnlp is pasted bellow
2) another problem here is the system did not have the jre installed earlier. how does system identified the jnlp file format if no jre available first time??
So rather auto download I have installed jre manually and was launching the application
thanks a lot,

    Hi,
    >>>>Map Selected Fields and substructures if Name are identical.

    I think this fields are enabled if you are change mode. I believe you might be in display mode. Click on the change button in mapping and check if those buttons are enabled or not.
    If the above doesnt help let us know ur SP level?

  • Unable to launch application with java web start (OILOM)

    I'm connecting to a remote Oracle console from a server, using "oracle integrated lights out manager". I go to "Remote Control" and click on "Launch Console". After that, it download a JNLP file, called "jnlpgenerator-16". I open it with Java7 -web starter- update 5.

    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.

  • Java web start running on windows NT4 work station

    I have installed java web start on a windows NT4 work station (service pack 6) with a directx v5. I successfuly launch the sun applications such as swing set 2, but I have some troubles concerning our software which used another look and feel than the default one. A system error is raised saying that the library ddraw.dll could not be loaded.
    I have unistalled and re-installed directx v5 but the error is still raised.
    Does any one can help me to solve this problem ?.
    Thank you.

    Hello Sim085
    thanks for your reply.
    Perhaps it would be easier for us to continue the programming with any kind of VisualStudio Produkt ;-), although we dont't had to think about OOP yet!
    Because of our new Network-Technology (Terminal-Server) we have to discuss serveral possibilities.
    I've read about JSP and ASP.NET, and I want to know if JSP or any kind of JAVA Program will run on a Terminal-Server.
    Are there any special aspects I have to know when running JSP on a terminal server from Microsoft? Is it better to program applications in JAVA or in JSP? ...
    Thanks

  • Java Web Start 1.6 fails to start application without Java Consol on Vista

    Hi All,
    I've faced with problem related to starting my application in IE 7 on Vista SP1 using Java Web Start (JRE 1.6.0_12 and 1.6.0_13). I suppose that issue appears after 11th update of JRE 1.6 since it works fine before.
    There were set settings to indicate initial and maximal size of the Java heap in the JNLP file.
    Application consist of 2 JAR files and they are signed with the same certificate.
    When user tried to start application there is no any activity after accepting certificate. After starting application javaw.exe just disappeared from processes list without any message or error.
    When I changed default setting in Java Control Panel to show Java Console, I noticed that the application began to start. But it's not a solution of the issue, since all customers cannot be required to turn on Java console.
    I believe this is a bug in JRE as the application starts with Java console and doesn't without it.
    When I browsed the web looking for the solution or an advice I found Release notes for 1.6.0_014 where it was said that 6u14 Java Web Start failed to launch and notifies that JARs were not signed, if an insecure Java system property was specified in a sandbox JNLP file. In spite of that 14th updated wasn't used and there was no notification I tried to start application without settings for the Java heap and it worked.
    Could someone help me with advice, since the application cannot be started with default heap size settings.
    Thanks in advance.
    Edited by: vovanst on Jul 28, 2009 8:06 AM

    Hi,
    as the 6u15 just arrived and the above mentioned bug should've been fixed (though I was unable to verify through the release notes), the error is still in there.
    We have no timestamped jars, neither ours nor the bouncy castle ones, all certs are valid, ours is self signed.
    6u13 runs, 6u14/6u15 won't.
    I followed the instructions here: http://bouncycastle.org/devmailarchive/msg10415.html to no avail.
    The bcprov.jar is wrapped in its own jnlp and referred as extension from the "main" jnlp.
    The interesting parts of the stack trace are these:
    Caused by (via getCause): java.lang.SecurityException: JCE cannot authenticate the provider BC
         at javax.crypto.Cipher.getInstance(DashoA13*..)
         at javax.crypto.Cipher.getInstance(DashoA13*..)
    Caused by (via getCause): java.util.jar.JarException: Cannot parse https://localhost:8443/deploy/bcprov.jar
         at javax.crypto.SunJCE_c.a(DashoA13*..)
         at javax.crypto.SunJCE_b.b(DashoA13*..)

         at javax.crypto.Cipher.getInstance(DashoA13*..)
         at javax.crypto.Cipher.getInstance(DashoA13*..)
    For me it seems there's a problem with resolving the url of the bcprov.jar, which would explain the lack of a delay which normally occurs when JCE verifies the signature of the bcprov provider classes. The error pops up almost instantly.
    I'm clueless what to do now. Did Sun really achieve to completely destroy JCE provider functionality in Javaws, forcing us to use an alternative implementation?

  • Java Web Start didn't install with j2sdk-1_4_2_04-windows-i586-p.exe

    I just uninstalled all my java stuff from my XP Pro system
    then re-installed... j2sdk-1_4_2_04-windows-i586-p.exe
    With the SDK installation... j2re1.4.2_04 also installed... I think this is the Java Runtime
    But, before I had a folder for Java Web Start... not I don't...
    AND, the file... javaws-1_2-windows-i586-i.exe
    refered to on the Java Web Start Installation page isn't on my system anymore...
    (It was in an older vrsion of the Java Runtime... ( I had 2 java Runtimes at once installed, that is why I uninstalled... and even though I had Java Web Start, it wasn't working... so I deleted everything and reinstalled the j2sdk-1_2_04-windiws-i586-p.exe.)
    I would just download the java Web Start but the docs tell me it should be installed when the SDK and Runtime are installed... so I worry if I got the installation correct.
    Can anyone please advise me of how to get things working again.
    thanks for any help - Will

    I fixed this broblem just install both JDK and JRE.

  • 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
    Markus

    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!
    Bye

  • Windows Printing vs Java Web Start

    I am having a hard time printing from a Java Web Start application to a printer attached to a Windows server. I don't have problems with this printer and other (i.e Mac) applications. When I try to print from the JWS app the job gets sent to the Printer window but the Status is "On Hold (Authentication Required)". If I click the Resume button I get prompted for my (Windows) username and password, after that the print job goes through normally. I noticed the Print window shows this job's username as "System Administrator". When when I print from a Mac application the username is blank and the print job goes straight to the printer. The Activity Monitor shows I am the owner of the JWS process. On Tiger web start just prints normally. This is very frustrating. Any ideas?

    I have tested this further and have additional observations.
    1. The problem is observed in java applications, like JEdit, not just web start applications.
    2. The scenario described in the original post applies to admin users. It is possible to work around the issue by creating a custom printing queue using the Advanced tab in the Printing CP. The normal Windows printing queue looks like: "smb://printServer:port/Printer". If you create a custom queue of this form: "smb://windowsUsername:password@printServer:port/Printer" then the java application will print without requiring further confirmation in the Print queue dialog.
    3. The scenario and workaround do not work with a standard user. With a standard user the java application presents a modal dialog that indicates a printing failure. The dialog does not get dismissed after clicking the OK button, but does close when the java application is quit. I have not found any work arounds that allow standard users to print.

  • Can we change the title of "Java Web Start" window?

    Hi while running our application into "Java Web Start" using jnlp configuration file, may I know how to change the title of Java Web Start Window.
    At present it show the title like "Java Web Start" I want to customize, is it possible? , How?

    As far as I know this is not possible. You can customize the splash window displayed with the jnlp how your told, but the title of the window cannot be changed.

  • 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).

  • 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

  • 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 :-(

  • 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.

    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.

  • Problem with win2000sp3 and Java web start

    I have JRE and Java web start (1.2.0_01, build b01) which come downloading file j2re-1_4_1_01-windows-i586-i.exe from sun.
    I have win2000pro running on my PC.
    I had updated win2000 to service pack 2 and everything was fine.
    Now i decided to update to service pack 3 (in the process I also updated other components) from Microsoft and:
    1) Java applets seem to be running fine within i.e.
    2) If i try to run an application from java web start my PC freezes and I have to restart it.
    3) Staroffice 6.0, which runs on Java, seems to be fine.
    I reinstalled both sp3 and jre etc, with no result.
    Is this a known problem?
    Thanks to all.

    I suspect that you have hit a known problem with Swing on Java 1.4.1 with buggy video drivers. Do you have an ATI card? They are the worst offenders. ATI released new drivers for its Radeon line today. They fix the problem.
