Forum Post: java.security.AccessControlException prompted when creating a load test script

I have used silk performer to record a load test with Oracle Applications R12 with oracle forms function. When I click in a oracle form function, the java console loaded but there is a error message returned: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.java2d)             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.checkPackageAccess(Unknown Source)             at sun.applet.AppletSecurity.checkPackageAccess(Unknown Source)             at sun.applet.AppletClassLoader.loadClass(Unknown Source)             at java.lang.ClassLoader.loadClass(Unknown Source)             at java.lang.Class.forName0(Native Method)             at java.lang.Class.forName(Unknown Source)             at oracle.forms.engine.Main.initDesktop(Unknown Source)             at oracle.forms.engine.Main.start(Unknown Source)             at sun.applet.AppletPanel.run(Unknown Source)             at java.lang.Thread.run(Unknown Source) java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.awt)             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.checkPackageAccess(Unknown Source)             at sun.applet.AppletSecurity.checkPackageAccess(Unknown Source)             at sun.applet.AppletClassLoader.loadClass(Unknown Source)             at java.lang.ClassLoader.loadClass(Unknown Source)             at java.lang.Class.forName0(Native Method)             at java.lang.Class.forName(Unknown Source)             at oracle.forms.engine.Main.class$(Unknown Source)             at oracle.forms.engine.Main.initDesktop(Unknown Source)             at oracle.forms.engine.Main.start(Unknown Source)             at sun.applet.AppletPanel.run(Unknown Source)             at java.lang.Thread.run(Unknown Source) #### try SE connect with aaofsapp1.hkairport.com:19105 New JavaScriptEngineRemoteClient (#102) connected to: aaofsapp1.hkairport.com:19105 Borland Recording Settings: Log-Level: 1 I've read the following document to open networks ports in firewall: http://community.microfocus.com/borland/test/silk_performer_-_application_performance_testing/w/knowledge_base/9422.which-ports-need-to-be-opened-in-a-firewall-for-silkperformer-to-connect-to-an-agent.aspx But still the error message cannot be fixed.
