Java Applet with Mysql ExceptionInInitializerError

Question

I'm using java applet with mysql connection. I used Netbeans to build paths. When my applet works in localhost, I got an error.

Exception in thread "Abandoned connection cleanup thread" java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "setContextClassLoader")
    at java.security.AccessControlContext.checkPermission(Unknown Source)
    at java.security.AccessController.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkPermission(Unknown Source)
    at sun.plugin2.applet.AWTAppletSecurityManager.checkPermission(Unknown Source)
    at java.lang.Thread.setContextClassLoader(Unknown Source)
    at com.mysql.jdbc.AbandonedConnectionCleanupThread.run(AbandonedConnectionCleanupThread.java:38)

I just use mysql-applet Netbeans. Can you help me ?

If you upgrade your MySQL Connector/J to 5.1.26 this should be fixed. Previously there was a call to 'setContextClassLoader()' which was removed for other reasons. See http://bugs.mysql.com/bug.php?id=68556
