Setting security policy

Question

I am using RMI and have to set the security policy by specifying a policy file on the command line.
My policy file is very simple and is below:
grant {
permission java.net.SocketPermission "*:1024-65535",
"connect,accept";
permission java.net.SocketPermission "*:80", "connect";
I tried looking up how I could set the policy from within my code so I don't have to use a policy file but couldnt' find anything clear on this. I am using Java 1.4 so any help would be appreciated.

Answer 1

Ok, that's not so simple but we'll try.
First define your permissions like to folowing:
SocketPermission sp1 = new SocketPermission("*:1024-65535", "connect, accept");
SocketPermission sp2 = new SocketPermission("*:80", "connect");
Then add them to a PermissionCollection object throu the add method. And this ProtectionCollection object is passed to a ProtectionDomain object together with your CodeSoure class.
It should look like this, but I'm not sure how to define the sourcecode agument in the ProtectionDomain constructor...
SocketPermission sp1 = new SocketPermission("*:1024-65535", "connect, accept");
SocketPermission sp2 = new SocketPermission("*:80", "connect");
PermissionCollection pm = new PermissionCollection();
pm.add(sp1);
pm.add(sp2);
ProtectionDomain pd = new ProtectionDomain(codesource, pm);
Anyway, hope it helped,
