Hi all,

I hope someone out there can shed some light on this problem.

I have a signed Applet that will FTP a selected file from the Client
back to the server. (signed Jar for Netscape, signed Cab for IE)

This applet works fine on the Windows platform (both Netscape and
IE) and on Netscape 6.1 for the Mac (OS 9, with MRJ 2.2.5)... However, IE5
on the Mac opens the applet window without the usual security warning dialog
that is normally presented to the user, then just sits there.

It looks like it's getting a security exception when the applet
tries to verify that the file actually exists (effectively trying to read
the client system). The following information appears in the Java Messages
window.

com.apple.mrj.JManager.JMAppletSecurityExc:
security.checkread: /photon/testfiles/SAMPLE.PS,
/photon/testfiles/SAMPLE.PS
at

com.apple.mrj.JManager.JMAppletSecurityOld.checkRead(JMAppletSecurityOld.jav
a)
at

com.apple.mrj.JManager.JMAppletSecurityOld.checkRead(JMAppletSecurityOld.jav
a)
at java.io.File.exists(File.java)

This happens using both the MRJ and the Microsoft IE VM. I can not
find any information on JMAppletSecurityOld, and very little that is useful
on the JManager. Apple's idea of documenting this class seems to be to put
the source code out as documentation, but I'm afraid that does not tell a
security newbie like me how to use it correctly.

I have picked up the MRJ SDK, but can't figure out if need to use
that, or if the problem is with the way I'm signing the Cab file.

Any insight, help, URLS, code fragments, that might help me resolve
this puzzle would be greatly appreciated.

Thanks,

Sue D.
