Java WebStart Popup window

843811

Is it posible to modify the JVM's security policy so that applications that run on webstart(which runs on the JVM) will not present the warning(i.e. "This application has requested read/write access to a file on the local filesystem. Allowing this action will only give the application access to the file(s) selected in the following file dialog box. Do you want to allow this action?") when a non sandbox type command is executed? I tried modifying the global security file giving any codebase all permissions, but I still get the pop up window message. Is the message unavoidable?
I am writing an application to be used by a client after he runs a cript locally to change his permissions. I don't want the popup to ever appear(not even the very first time).

That kind of dialog should only show up, if you use the JNLP File Services.

I don't want the popup to ever
appear(not even the very first time).

I would rather sign all jar files and give the all permissions rights in the jnlp file.
Then the user will get presented the certificate one time for accepting.
This will be stored in the Web Start cache and thus not seen again during following runs.
