[rules-users] RuleAgents and containers

[Pavel Tavoda]

In default setup of many servers (which I know) and java has no
prohibited reading of files outside ear. You can read changeset and
rule files from specific directory e.g. (/etc/rules/...). Or you can
use user.home property. We are using it without problems.
However you can use other mechanisms which are more appropriate for
your setup. For example for clustered environment and better
management I will store rules to database or you can use Guvnor.
