java.security.AccessControlException: access denied

Hej,
Jeg har en ret simple applet som forbinder via en port (4444). Jeg har udviklet appletten under Netbeans 3.5 og er nu ved at portere projektet til Netbeans 4. Når jeg i Nb4 prøver at etablere en port forbindelse får jeg følgende meddelse:

java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:4444 connect,resolve)

Hvad stiller jeg op med dette. Kører jeg appletten fra min Apache webserver viker det fint. Jeg vil gerne kunne afvikle den fra Netbeans.
