Throws AccessControlException if used HTTP Tunneling
Please see the code below...
I am getting host and port in applet itself and passing it to ServerManager
//---------- code inside applet ---------------//
String host = getCodeBase().getHost();
String port = getCodeBase().getPort() == -1 ? "" : ":" + getCodeBase().getPort();
//--------- code of ServerManager -------------//
String url = (host + port);
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.HttpNamingContextFactory" );
props.put(Context.PROVIDER_URL,"http://" + url + "/invoker/JNDIFactory" );
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
try {
InitialContext ctx = new InitialContext(props);
Object sessionRemoteRef = ctx.lookup("testejb.session.MySessionBean"); //Line no 74
}catch(Exception e){
e.printStackTrace();
}
My problem is when i access the applet from browser using address http://parag:8080/mine/TestApplet.html,
everything works fine but when i try to access it using http://localhost:8080/mine/TestApplet.html
it throws the following error (TestApplet.html is a simple html file with applet tag)

I think it should resolve localhost to parag as parag is the name of my own machine
but it is not doing so.
Can someone please tell me why it throws AccessControlException when accessing from localhost ?
Thanks and Regards,
