Well, it's the same on both Windows and Linux and all other platforms that Java run on, but I digress. :)
Java has its internal security system for sandboxing of code. Various operations in the standard class library are protected by a system of privileges granted to individual classes. If you don't accept Haven's code signing certificate when you launch it, the Haven classes won't get the privileges they need to run. The JNLP client should ask you to accept the certificate when it starts a JNLP application, but I don't know how the various JNLP clients behave. Are you using Sun's implementation, NetX (which comes with OpenJDK) or something else?
