don't know very much about applets, and I'm trying to learn more using a book. I've already done some applets that contain simple animation, but when I tried drawing an image I've got stock on this: access denied( "java.io.FilePermission" "[image]" "read"). Anyone who can help me? import java.awt.Graphics; import java.awt.Image; public class Wave extends java.applet.Applet{ Image waveimg; public void init(){ waveimg=getImage(getCodeBase(),"wave.jpg"); } public void paint(Graphics g){ g.drawImage(waveimg, 10,10,this); } } java applet awt accesscontrolexception share|improve java security accesscontrolexception access denied java util propertypermission this question edited Jul 28 '15 at 12:42 HassanF 1801212 asked Jul 28 '15 at 12:07 Andreea 1112 Most likely, the applet or its container does not have permission to read from the provided URL.

How are you loading the applet? Using applet viewer? Using the some HTML loaded off the local file system in the default browser? Using some HTML loaded off a local server in the default browser? This information might make all the difference about when the applet will succeed or fail. –Andrew Thompson Jul 29 '15 at 12:07 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote This is because Apple
