Using two signed jars for an applet

Hi!

I want to provide a solution where i have one jar-archive where the
applet itself and all dialogs or what ever are in it and one
jar-archive where i have my utiliy-classes which provides a
SocketConnection for example. To use the SocketConnection the
jar-archive has to be signed but it seems to me, that it isn't,
because i always get a AccessControlerException (access denied). Both
jar-archives are signed but it doesn't work.

Can anyone help me?

Thanks in advance, Chris

I think they also have to be signed with the same key. Are you
regenerating your key on every sign?

I did the following:
1. i created a new key with the keytool
2. i signed both jar-files with the jarsigner and used for both the
key i have created with the keytool, so i think i use the same key, or
not?

As i tried to use only the jar-archive with the utility-classes as a
signed jar i didn't get the dialog where i have to grant the
permissions, that is why i think, that there are some problems with
this jar-file.

check the jar files with winzip to make sure they are complete. See

and http://mindprod.com/jgloss/jar.html
