Drools, Jboss AS, Dynamic Bean Generation ------------------------------------------ Key: JBRULES-2040 URL: https://issues.jboss.org/browse/JBRULES-2040 Project: Drools Issue Type: Task Security Level: Public(Everyone can see) Components: All Affects Versions: 4.0.7 Environment: Jboss Application Server v4.2 Drools 4.0.7 Javassist JDK1.6 Reporter: Shawn Ritchie Assignee: Mark Proctor Labels: Bean, Creation, Drools, Dynamic Fix For: 6.0.0.Alpha1 Attachments: JavaApplication.rar, rule3.drl, rules2.drl, SampleApp.rar The issues is this guys i am creating a bean dynamically in this simple example i have an arraylist of strings which will create a private field, and a getXXX and a setXXX method for each of these fields The problem arises when i try to load the .drl file in the package builder which gives me the follow error (SEE BELOW) I suspect it has something to do with the class loader or the package structure in the rules? Any suggestion reading material or help would be greatly usefull the code i have loaded is a simple application which replicates the error 22:20:59,435 ERROR [STDERR] Unable to create Field Extractor for 'name' of '[ClassObjectType class=com.beancreation.personXYZ]' in rule 'Credit Allowed' : [Rule name=Credit Allowed, agendaGroup=MAIN, salience=0, no-loop=false] 22:20:59,435 ERROR [STDERR] Rule Compilation error : [Rule name=Credit Allowed, agendaGroup=MAIN, salience=0, no-loop=false] com/beancreation/Rule_Credit_Allowed_0.java (1:0) : The type java.lang.Object cannot be resolved.
