Applets and socket problem 1

[Raywall]

I'm working on a chat program and the clients must be done using applet.The problem is that I have one error when the client connects:
something with socket perimision.If I run the server and the clients on the same machine everithing works just fine so I guess there's some problem with security when applets are used.Is there something special that I must do or the program should work without declaring Socket permisions? I'm somehow new in java so,if there are some basics using sockets in applets my mistake
Also please tell me how can I display Images in a frame(awt).
Thanks...

Are the applet and servlet's codebase running on the same server ?

I'm sorry but I don't know what a servlet is.
I'll try to answer somehow. The server is running on a machine and has no interface to display, and the clients from different machines must connect to the server. The chat is designed for LAN but every client must have applet as interface.I used ServerSocket and Socket.
Bassicaly, on the server I have:

ServerSocket server=new ServerSocket(1300);
Socket client=server.accept();

And on every client :
Socket client=new Socket(server_name,1300);

For the last line I get the socket permission error and I don't know why.
I hope you can help me with this.
Thank you...

Sorry, I read "socket" as "servlet". Applets are tied down tightly as to what they can and cannot do. This explainas it better than I could :

You will most likely need to create a signed applet/signed jar file. Google for how-to's, here are two :

I'll look at those links.
Thanks.
