Signed applet works only with jre 1.6u10 beta...

[smartizzz]

Hello!

I made a simple java applet which can retrieve a distant http page.
I signed it using keytool&jarsigner from the sdk 1.6u10

I run it with the jre 1.6u10 beta and it works fine!!


But when I try to run it with an other version of java, it doesn't work because of an error of socket permission...
I tried with jre 1.6u7 and 1.4.2

Do you have an idea about that?
I precise that I never modified my policy files...
And i tried also to sign the jar file with the sdk 1.4.2 but it's the same as before

Thanks
