Hi again,

JImageUpload is installed and running but there is a very weird issue bothering ALL users on IE and Firefox:

50% of the times it works just fine, loads the applet, uploads photos and everything.
But the other 50%, the browser shows this fancy Orange Java Loading animation (as always) but suddenly it freezes the entire browser, the applet is never loaded (this animation stays frozen) and the only way to close the browser is killing the process on the task manager.

Additionaly, the java console shows this error:

java.lang.NullPointerException

at sun.plugin.AppletViewer.loadJarFiles(Unknown Source)

at sun.applet.AppletPanel.runLoader(Unknown Source)

at sun.applet.AppletPanel.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

At first sight it would seem like it doesn't fin the jar files but actually i faced this problem before and when it doesn't find them it pops a different error, so this time i just ran out of ideas.

Again, the weird part is that this happens only sometimes but frequently, and the rest of the times it works just fine, but it happens to both IE and Firefox. and ideas on where could I start ?

Thanks in advance.

This problem seems to be in JavaPlugin on JAR loading. Which JRE version are you using ?
I've found some references in the SUN bug database at:
http://bugs.sun.com/bugdatabase/view_bu ... id=6391104

Did you modify the JavaScript packaged with JImageUpload ?
In the SUN report, they said it happens when applet is refreshed.

How can I make javascript work on my computer? I've done the "enable javascript" thing, and I've downloaded the update several times and it always says it is successful, but still I can't go on any websites. I also tried downloading it to my desktop. it still always says, "you need to update or enable javascript". how else can I fix it?
