My, aren't we snippy?
OK, well if you read this then note that those rules shouldn't work in any environment
for the reason previously stated. (Use of an undeclared variable in the RHS.) If they
are working then something odd is going on, and since you say they are then...something
odd is going on.
BTW, the error you're getting now is an mvel error:
http://mvel.codehaus.org/Strong+Typing+Mode
Since you're currently getting it for "$severity" and not just
"severity" even though the former does not currently appear in your rule...well
that's the odd bit I mentioned before. Somewhere $severity (along with $weight,
$factor, and $tempScore) is being declared, but it's not in the text of the rule as
you've provided it.

$severity was never defined. In the RHS remember that you can write pure java. So if you
want a variable called severity you should declare it as:
String severity = $patient.medicalHistoryBleedingRiskFactors.gastritis;
Greetings. 2010/12/3 John McKim <jmckim(a)comcast.net>I'm having a problem that I
can't seem to figure out. I have rules that run in a client program with no problem -
about 125 rules in all. When I try to run these same rules in an App Server (GlassFish) I
get several rules (about 5) that have an error on initialization. Here is the error
message followed by the rule.

Yes.. make sure that all the variables that you use at least in the left
hand side of the expressions are declared.. so when you us it again it will
be there..
