why does Web start gave an "Unsigned application requesting unrestricted access to system" error when it is signed?

experts,

I have struggled with this for a while and don't know why i got this error when launching web start application? the far file is signed and I could just use "java -jar my.jar" to run it without problem. So, I am really confused why it gave me error saying the jar file is not signed? thanks.

by the way, the jar file is varified.

yes, it is verified signed.
I think I added one extra security by accident, but it should not affect the result since it works for the other jnlp. any clue? thanks.

all looks fine, that error suggests it is not signed so all I can suggest is double check that the following is signed:

http://localhost:8090/pipeline/wjhk.jupload.jar

and how are you using it?

can you also delete the jar from your local cache and try and reload it in case its not uploading the jar from the server and instead using an old cached version.
