ServerSocket Security problem on MS Java (In an signed applet)

Hi all,

I have a problem with creating ServerSocket in MS Java.

I have a ServerSocket in an applet wich is a router for other applets that can not connect trough firewalls. In this router I implemented a http tunneling to avoid firewalls.

The problem is that on MS JVM when creating a ServerSocket I have a security exception even my applet (the router) is signed.

There is another solution for MS JVM? (I'm refering do not use ServerSocket) or how can I avoid this security exception?

Thx,
Black_NM

Probably not signed correctly - do some fine inspection ;-)

Is correctly signed.
On Java Sun it works fine.

 Do you need to use MS "java"? Why not stick with the version we all use?

Is not my choice. The client want to work in windows without any other downloads. (I'm referring to the Java plug-in download)

>>and also the cab file.

But obviously not adequately, or you wouldn't be getting security errors

So you are sure that with a applet signed it have to work on MS?

I signed the code with netscape security.

if you remove the cert from IE, and reload the applet does it ask you to trust that cert?
