New to Java

Hello,

My PC is on Vista SP1 and java is installed :

C:\java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

When I try to open a .jar file - by double click on the file in Explorer or putting the file directly on the IE browser -
the window "Java starting" appears follow by a second one with the error message "Unable to lauch application"
("Impossible de lancer l'application" in french)

In the dtails i can read :

Exception :

CouldNotLoadArgumentException[ Impossible de charger le fichier/l'URL spcifi : C:\Users\Sad\AppData\Local\Temp\javaws11]
at com.sun.javaws.Main.launchApp(Unknown Source)
at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

Exception boucle :

java.io.IOException: File too large
at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)
at com.sun.javaws.Main.launchApp(Unknown Source)
at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

It is very strange while I'm sure java is installed and work on my computer

I have an other java application wich run well but I need to use the strange shortcut created by the install programm to lauch it

This shortcut is : C:\Windows\System32\javaws.exe "C:\Users\Utilisateur\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\36\db05364-3205c125"

But I need to be able to open other single .jar files directly by clicking on it in Explorer or by an other way

I really don't know what happens or what to do for that

So I thank you i advance for your answers
