signing external library

Thread view: 
wzhang - 03 Dec 2003 19:36 GMT
Hi,

I have a jar file for my applet. My applet uses a lot of external
library jar files. I signed my own jar. But it still gives me security
exception if I want to load local file into applet. If I sign the
external lib jar files as well, the applet works fine. But I do not
want to sign other people's code. Is there a way to work around this
problem? I am not the only user of this applet, so I cannot change
policy file to grant permission for every ther user.

Thank you very much.

hi,
there is no way except what you did, sign the other code.
So, if the other code is signed, WebStart (for example) creates a
security
exception and you have to sign all the code by yourself.
