server.properties
This file is located in Helma's installation directory. It contains system level properties that are used internally by Helma for configuring the server. See Server and Application Properties for a complete overview.
Many of these properties also can be defined in an app.properties file. Any property that is set there will overwrite the appropriate setting in server.properties.
Example
# Setting a custom locale:
country = AT
language = de
# Defining a mail server:
smtp = mail.domain.dom
