Hi folks,I'm new about developing Java applets and I need some help.I'm developing a Web Application based on JSPs and Tomcat in Netbeans.I've also developed a Java Applet which its package has some classes.This Applet connects to a Sybase Database (JConnect) in order to querysome information. It works fine when I run the Applet Class atNetbeans.The Jar containing this Applet (and the Jar supporting the DB driver)is embedded into a JSP of my Web Application through JSP Plugin tag.When I call for this JSP (where the Applet is embedded) I get thiserror (at the Client Java Console):java.security.AccessControlException: access denied(java.net.SocketPermission ... resolve)	at java.security.AccessControlContext.checkPermission(Unknown Source)	at java.security.AccessController.checkPermission(Unknown Source)	at java.lang.SecurityManager.checkPermission(Unknown Source)	at java.lang.SecurityManager.checkConnect(Unknown Source)	at java.net.InetAddress.getAllByName0(Unknown Source)	at java.net.InetAddress.getAllByName(Unknown Source)	at java.net.InetAddress.getAllByName(Unknown Source)	at java.net.InetAddress.getByName(Unknown Source)	at java.net.InetSocketAddress.<init>(Unknown Source)                ...How can I fix it?Regards
