First off, yes, I am an expert Java programmer, not just a Drools expert - yet. If you
took the time to read the post, you would have found that the answer that was provided to
me “DIDN’T WORK”. Never mind, I’ll figure it out myself. Goodby!

You made the same error in three other places. Fix them. Are you familiar with the java
language?

Thanks for the reply Mauricio. I tried what you said using this modified rule:
rule "medicalHistoryBleedingRiskFactors.gastritis rule"
salience 20
when
# find patients who indicated that they have MedicalHistoryBleedingRiskFactors:
gastritis
$patient : Patient(medicalHistoryBleedingRiskFactors.gastritis > 0)
then
String severity = $patient.medicalHistoryBleedingRiskFactors.gastritis;
$weight = 5;
$factor = .1;
$tempScore = $factor;
$tempScore = $tempScore * $weight;
$tempScore = $tempScore * $severity;
# Now add this risk score to the accumlated risk score
$patient.score = $patient.score + $tempScore;
$patient.problem = new
String("MedicalHistoryBleedingRiskFactors.gastritis");
end
But I got this exception in the client (I am using 5.1.1 by the way):
Exception in thread "Thread-4" java.lang.RuntimeException: Unable to build

When I took out the String severity and used just $severity: it works fine. Just on the
App server does it fail.

that's weird.. you are using a varible that you never define in the Right Hand Side.
$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;

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.
*******************************************
SEVERE: java.lang.RuntimeException: Unable to build expression for 'consequence':
[Error: not a statement, or badly formed structure]
[Near : {... $severity;
....}]
^
[Line: 1, Column: 233] ' $severity =
$patient.medicalHistoryBleedingRiskFactors.gastritis;
$weight = 5;
$factor = .1;
$tempScore = $factor;
$tempScore = $tempScore * $weight;
$tempScore = $tempScore * $severity;
// Now add this risk score to the accumlated risk score
$patient.score = $patient.score + $tempScore;
$patient.problem = new
String("MedicalHistoryBleedingRiskFactors.gastritis");
' : [Rule name='medicalHistoryBleedingRiskFactors.gastritis rule']
**********************************************
rule "medicalHistoryBleedingRiskFactors.gastritis rule"
salience 20
when
# find patients who indicated that they have MedicalHistoryBleedingRiskFactors:
gastritis
$patient : Patient(medicalHistoryBleedingRiskFactors.gastritis > 0)
then
$severity = $patient.medicalHistoryBleedingRiskFactors.gastritis;
$weight = 5;
$factor = .1;
$tempScore = $factor;
$tempScore = $tempScore * $weight;
$tempScore = $tempScore * $severity;
# Now add this risk score to the accumlated risk score
$patient.score = $patient.score + $tempScore;
$patient.problem = new
String("MedicalHistoryBleedingRiskFactors.gastritis");
end
As I said, this rule runs fine in a client app – when I run the same rules in app server I
get an error. This is only happening in 5 out of 125 rules, and only during
initialization using builder.add(ResourceFactory.newClassPathResource(file).
Thanks.
