Server Utilities

The following utilities are bundled with BackOnline. In addition, the Java source code for these utilities, is provided as an example for how to extend the BackOnline Server via Java Servlets (for more information on the Java Servlet Technology, visit http://java.sun.com/products/servlet/)

Managing The User Database

There are a couple of ways to add new user records:

Through a web browser using the basic "Add User" functionality provided in the BackOnline Server.
Using raw SQL via database tools.

NOTE: If you are using the InstantDB database shipped with BackOnline, then you must use the first method mentioned above to add users when the BackOnline Server is running. InstantDB does not permit concurrent access from different Java Virtual Machines (JVM).

The Add User web form (show below) can be used to add a user -- to delete/update user records, you have to use tools available for the user database (see below). The add user form/script can be accessed via a web browser by pointing to http://<BackOnline server host name/address>:<HTTP port number>/adduser.html (e.g. http://localhost:55556/adduser.html).

To add/delete/modify user records using raw SQL, please inspect the following sample files in the server/database directory for quick examples of how to work with InstantDB (note: do not use these when the BackOnline Server is running):

db-sql-script.bat
db-sql-browser.bat
db-create.sql
db-show.sql

Client Monitor

The Client Monitor is accessed using http://<BackOnline server host name/address>:<HTTP port number>//ClientMonitor (e.g. http://localhost:55556/ClientMonitor). It can be used to monitor clients using the BackOnline Server and also for disabling further logins. The Browser's "Refresh/reload" function can be used to view updated information. Optionally, the Submit button, found on the Client Monitor screen, can also be used to provide "Refresh" functionality.
