[rules-users] RuleBaseImpl Error - Help needed

Hi, I am a beginner. I am using DSL Syntax. I get errrors like org.drools.rule.InvalidRulePackage: unknown:7:48 mismatched token: [@16,48:49='&&',<55>,1:48]; expecting type ')' unknown:8:0 Unable to expand: ;. Due to Expression was not expandable: at org.drools.rule.Package.checkValidity(Unknown Source) at org.drools.reteoo.RuleBaseImpl.addPackage(Unknown Source) at student.DroolsStudent.main(DroolsStudent.java:50) Where can i get the API documentation for RuleBaseImpl classs and other classes like WorkingMemoryImpl ? Are there any sets of DO's and DONT's to be followed frame rules in DSL Syntax ? -- View this message in context: http://www.nabble.com/RuleBaseImpl-Error---Help-needed-tf3308727.html#a92...
