Java Web Start & JNLP - Webstart hangs

Hello,

I have an app that I am running in online mode. I have the shortcut tag set to online="true" and I do NOT have the offline-allowed tag in my JNLP.

When the server that the app checks is not running, what should the behavior be?

Under 1.5.0_11 and under 1.6.0 on Windows, it fires up, displays the Java splash screen, and then just stops. The splash screen goes away and it leaves a lingering javaw process.

There is no error message, no other feedback.

I searched the forum a bit, but perhaps I missed this topic already. Could someone point me to how to get it to display an error message, or if it is a bug, point me at the known issue?

Thanks in advance!

# 1

As an addendum, it appears that even if I specify offline-allowed and online="false" for the shortcut, whenever I attempt to launch from the cache viewer or from the shortcut the behavior is the same as in my original post. In light of that, is this a more general bug that is tied to all the questions that have recently been posted with respects to the offline-allowed behavior and other unresponsive scenarios?

Thanks again!

I have the posted the exact same problem on this forum a few days ago. We have experienced this on jre 1.5 and jre 1.6 versions.

if the hang is in the java process, you should get the stack trace when the hang happens and post it here.

easiest way to do so is go to your jre/bin directory, make a back up of javaw.exe, and then overwrite javaw.exe with java.exe.

now invoke your app with java web start again and make it hang. this time when java web start starts the java process, it should start up a console window as well (because javaw.exe is replaced by java.exe), and then when the hang happens, you can press ctrl-break in the java console window and get the stack dump.

Just tried replacing javaw with java and the popped up console is completely empty, still fails to launch although it is less frequent. Still an intermitant problem.

Also have looked through the deployment home and this is the contents of the log file:

<?xml version="1.0" encoding="windows-1252" standalone="no"?>

<!DOCTYPE log SYSTEM "logger.dtd">

<log>

</log>

so nothing there either

does the app hang or just silently exit ?If it hangs, in the console window (java.exe), press ctrl-break to get the stack dump.

# 6

The stack trace from the console (using CTRL-Break thanks)

did u do "update check=always" in the jnlp file ?Seems like java web start is trying to do an update check, but never got reply from server, so it keeps spinning.

I am having the same problem & hope someone can help.

Here's my jnlp file (also tried it with <update check="background"/>:
