[rules-users] Exception error when using RuleAgent

[kissro at lidp.com]

Hello,

I created a rule in BRMS and downloaded the package to a directory.  I'm
using RuleAgent to load the RuleBase using the following code:

RuleAgent agent =
          RuleAgent.newRuleAgent("/brmsunderwritingrules.properties");
RuleBase ruleBase = agent.getRuleBase();


I'm getting the following errors.  Could someone tell me what I'm doing
wrong and/or how to fix this please.
