OK I think I am beginning to see the light.
I have got the list of system properties which include "user.dir",
"user.home & "user.name".
So far so good. And they are easy to get at as follows:

    startProperties = System.getProperties();
    System.out.println(startProperties.getProperty("user.name"));
    System.out.println(startProperties.getProperty("user.home"));

Now can I add to the list of system properties.
I thought that if I ran the following:

    java -DSystem.userapp_prefs="\\myserver\data\users"

I could use this code to get the value of a new system property
"userapp_prefs".

    startProperties = System.getProperties();
    System.out.println(startProperties.getProperty("user.name"));
    System.out.println(startProperties.getProperty("user.home"));
    System.out.println(startProperties.getProperty("userapp_prefs","NOT
SET" ));

This does not seem to work.

The following does work. Using "myprefs".

    java -Dmypref.userapp_prefs="\\myserver\data\users"

    startProperties = System.getProperties();
    System.out.println(startProperties.getProperty("user.name"));
    System.out.println(startProperties.getProperty("user.home"));
   System.out.println(System.getProperty("mypref.userapp_prefs","NOT
SET" ));

Any thoughts.

Many Thanks

Kevin
