System.getSecurityManager(); is null

Hello all,

I've written some code that connects to the repository, loads an image
(using ImageIO.read()) and i wish to store that image in the JCR.

The problem is; as soon as i make a call to ImageIO.read() i am thrown an
exception; reason for the exception is [SecurityManager security =
System.getSecurityManager();]  System.getSecurityManager() returning null
somewhere in the File class. I've never really needed to
'setSecurityManager' as such before; is this something to do with
Jackrabbit? Any ideas how to solve this?

Thanks
Neville

There is a call [fs.checkAccess(this, FileSystem.ACCESS_READ)] that is
returning me false. The file is NOT readonly and the owner is Everyone so i
guess all permissions are in place (using Windows Vista). Dont know why its
happening.

I now am quite sure it has nothing to do with Jackrabbit; sorry about the
post.

Thanks

I take it then that bioimagene is a standalone application, and not one that runs in a web server or applet, or container of any kind?

Could you provide the affected code snippet and (full) stacktrace of
the exception? Otherwise it is pure guessing.

But I would think that it is not related to Jackrabbit, especially if
it happens on the ImageIO.read() when reading from your file, because
at this point Jackrabbit as the target of the stream is not involved
yet.

Regards,
Alex
