Welcome to the JavaRanch. I've removed your email because we prefer that you
use the forum, not email.
Are you talking about a browser plugin? I'm not aware of any browsers that use Java as a plugin language (Firefox uses JavaScript, IE uses C++ or C#). A Java
Applet will not work because it runs within the browser sandbox and can't prevent pages from being loaded. If you really want to use Java, you may be able to write a proxy and set up your browser to go through it.
Since this has nothing to do with
Struts, I'll move it to a more appropriate forum.
