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!

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 <jmc...@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. ******************************************* 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).
