java - How to close frame within applet? -

-

Friends to close the frame inside applet ... my program is working, but the problem is trying The frame that will be made is not locked in the applet ... What should I do ... This gives me the exception when closing the frame window: 

  c: \ jdk1. 6.0 \ bin> appletviewer me.java Exception in thread "AWT-EventQueue-1" java.security.AccessControlException: java.security.AccessControlContext.checkPermission (AccessControlContext.java:323) java.security.AccessController.checkPermission And denied (java.lang.RuntimePermission exitVM.0) Access (AccessController .java: 546)   
 This is my code:  
  import java. Awt. *; Import java.applet *; Import java.awt.event. *; / * & LT; Applet code = "me.class" height = 500 width = 500 & gt; & Lt; / Applet & gt; * Width from frame / string {string msg; From the public () {msg = "This is the frame"; AddWindowListener (new window adapter) {Public Zero Window Closure (WindowEvent e) {System.exit (0);}}); } Public Zero Color (Graphics G) {g.drawString (msg, 10,100); }} Public square I expand the applet (public zero init () {from s1 = new to ()) s1.setSize (400,400); S1.setVisible (true); S1.setTitle ("Java Gamer"); } Public Zero Color (Graphics G) {g.drawString ("This is Applet", 10,100); }}    
 
 
  System.exit (0);   
 Applet is not allowed by sandbox,  Even if the applet is completely reliable.   
 But to improve it, the stand-app app ( frame  /  JFrame ) & amp; Use it with a link / button on a web page. JWS works on Windows, OS X & amp; * Nix. Then the frame can call  System.exit (n)  at any security level.

I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
