Applet AccessControlExceptions using Netscape and Java plugin

Question

I get the following AccessControlException when running a simple applet that tries to connect to an RMI object when using Netscape Communicator 4.5 with the Java plugin supplied with JDK1.3
java.security.AccessControlException: access denied (java.net.SocketPermission 10.195.57.34:1489 connect,resolve)The HTML page contains the following code:
<embed type=application/x-java-applet;version=1.3
code=test.AppletTest archive=AppletTest.jar width=800 height=600>
</embed>I have modified the default policy file C:\jdk1.3\jre\lib\security\java.policy with the following:
grant {permission java.security.AllPermission;};
With the above change the applet works when using appletviewer but if I remove this change I get the same AccessControlException as I do with Netscape.
This suggests that the Java plugin is not using the default policy file. What am I doing wrong / how can I fix it?
Thanks,
Neil

Alon,
Thanks for the information. The fact that appletviewer and Netscape may be using different security files because of having different java.homes certainly explains the differences I'm experiencing between the two.
I've now modified C:\Program Files\JavaSoft\JRE\1.3\lib\security\java.policy which now reads as follows:
grant codeBase "file:${java.home}/lib/ext/*" {
  permission java.security.AllPermission;
grant {
  permission java.security.AllPermission;
};but I've not changed C:\Program Files\JavaSoft\JRE\1.3\lib\security\java.security. Unfortunately this still doen't work with Netscape. In your reply you mention changing java.security files - am I making the wrong changes?
