We were surprised to see Java on our Serv-U server since the documentation states that Java is only a requirement for a client. But closer reading of the document at
http://www.solarwinds.com/documentation/serv-u/default.htm#ServUMinimumRequirements.htm shows that the document clearly needs help. For example, the option to use database management systems, LDAP, etc are under CLIENT requirements...So I am going to GUESS that Java is required and the document at the URL should be updated?
