New server class with useful options
Hi all,
I've attached a modification of the main server entrypoint class with
some useful options added. There are two additions:
i) The "-c" option will cause the server to create a new database (just
like the install tool) if it doesn't find a config.properties file in the
specified directory.
ii) the "-u<name>" option adds user <name> to the database with the first
available id above 1024 (if that user is not already in the database).
The net effect of these two additions is to speed up debugging. You no
longer have to run install before starting the server if you just wiped
your database; a fresh database will be installed if needed. You no longer
have to run the admin-tool before using a new database to add yourself as a
user.
(This also means that the following code can be removed from line 149 of
Env.java:
try {
userManager.newUser ("daniela", (short)1);
userManager.newUser ("gerd", (short)2);
userManager.newUser ("lars", (short)3);
}
catch (Exception e) {
}
and added to bin/ozone and bin/ozone.bat where it is more obvious.
)
Later,
\x/ill :-}
