The first time you run this application, the table will be created in the database. An error message will be printed by the J2EE server because it tries to drop the table, but the table does not exist. Ignore it.
The display pages are not automatically refreshed when a new alarm is received. To be done in a future version.
Filter names cannot contain "space" characters.
Sending many alarm messages concurrently with InstantDB as the database will not work (a deadlock will lead to a transaction timeout, and a delay on servlet display). This can occur with every database that cannot handle multithreading properly.
