in an html page. Standalone I'm using the same JDK as I am with the plugin.

I've signed the Applet.
I've configured the security policy for the plugin to allow all permissions.

------------------ java.policy -------------
grant codeBase "http://dev.caughey.com/-" {
permission java.security.AllPermission;
};
--------------------------------------------

Here is the out put from the Console window.

I have configured the plugin VM parameters with
-Djava.library.path=J:/javacomm

This is where i have installed the dll and placed the javax.com.properties
file which javacomm require.

If there is a better way to do this, I'm al ears. I hat the fact that I
have to have the user manually
modify the java.policy and place the two files on their file system.

Primarily i'm looking to get this working.


Thanks in advanced,
Michael
