Please could you help ?
I am attempting to develop an application that reads and writes to a database
on a locally networked Sun server.
I have executed code including the following snippet, using the JDK 1.0
appletviewer, as Netscape Navigator 2.0 does not produce any apparent result
Produces file dialogue box } FileDialog fd = new FileDialog ( this, "FD" );
} fd.show ();
Shows selected directory } string = fd.getFile ();
and file } System.out.println ( string );
} string = fd.getDirectory ();
} System.out.println ( string );
File dir = new File ( string );
Produces the exception } if ( dir.exists () )
message below } {
System.out.println ("Dir exists");
}
*** Security Exception: file.read:/home/amast/Java/experiment/ ***
sun.applet.AppletSecurityException: security.file.read:
/home/amast/Java/experiment/
at sun.applet.AppletSecurity.checkRead(AppletSecurity.java:266)
at sun.applet.AppletSecurity.checkRead(AppletSecurity.java:237)
at java.io.File.exists(File.java)
I suspect that it is a Systems Administration issue, and would be grateful if
anybody could refer me to some on-line documentation describing what might
be required,
so that I could pass this on to the Systems team.
Many thanks, Alan Masters.
