can place a file in your winnt/profiles on the remote machines you are using. I just did this and it was
much easier than the first route.
The file is called java.policy and is automatically generated by running policytool in your jdk.
It looks like this:
/* AUTOMATICALLY GENERATED ON Thu Jun 08 11:50:01 EDT 2000*/
/* DO NOT EDIT */
grant {
permission java.security.AllPermission;
};
Note: read about java security and the risks of having policys set like this
