Reading Client Windows Registry through browser

[nareshnettem]

Hi,

I am trying to read the Client Windows Registry by using an applet but it is throwing the following error in java console

java.security.AccessControlException: access denied (java.io.FilePermission <<ALL FILES>> execute)
at java.security.AccessControlContext.checkPermission (Unknown Source)
at java.security.AccessController.checkPermission(Unk nown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkExec(Unknown Source)
at java.lang.ProcessBuilder.start(Unknown Source)
at java.lang.Runtime.exec(Unknown Source)
at java.lang.Runtime.exec(Unknown Source)
at java.lang.Runtime.exec(Unknown Source)
at RegQuery1.start(RegQuery1.java:63)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

Is there any other approach to read the client Registry entrys other than applets?

please do the needful.

thanks in advance

regards,
Naresh.

I think you need to have the user install a full-blown application. Applets are "sandboxes" cut off from spying on or sabotaging the user.

thanks for your reply

we should sign the jar file for accessing the local filesystem from the
applet. for that I followed the below procedure to sign the jar:

Let Applet Name is MyApplet

keytool -genkey -alias MyApplet -validity 365

We have to provide all information about our locale. Fill all and then
sign the applet with jarsigner

jarsigner MyApplet.jar MyApplet
