Thou shalt edit the config.xml or go to
http://srvr:port/console and
login with system and password. Its called config.xml here but web.xml
I think is the general name used in Tomcat and others.
srvr

ort is the ip or machine name for srvr and for port try 80, 7021,
or 7041 I think.
E.g....

It's all XML so you can make it work by looking at the other XML. Best
way is to use the GUI. Drill into services or something like that. A
lot more flexible than the .properties file. Oh yeah!
Best luck, TimJowers
