[rules-dev] New Bee

Hi, I am very new to Drools. I need to know from where I can get some resources on DSL Syntax in 4.0. Examples etc. I am working on a project which used Drools 3 and my job is to upgrade it to 4.0. I am able to get everything compiled but getting stuck at loading DSLs. For example: I am getting an exception like: An exception occurred while attempting to parse a Validation rule in ABC Failed to add the compiled rule package to the RuleBase cause by: Unable to resolve ObjectType 'orRiskTO' : [Rule name=Certificate] Unable to resolve ObjectType 'orRiskTO' : [Rule name=Certificate, agendaGroup=Rating, salience=0, no-loop=false] Rule Compilation error : [Rule name=Dwellings, agendaGroup=Rating, salience=0, no-loop=false] rating/Rule_Dwellings_0.java (36:39) : A method named "intValue" is not declared in any enclosing class nor any supertype, nor through a static import at org.drools.rule.Package.checkValidity(Package.java:409) at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:262) at com.citizens.ratebook.RatebookRuleBaseFactory.buildValidationsRulebase(R atebookRuleBaseFactory.java:168) ... 29 more Saleem Lakhani saleem.lakhani(a)citizensfla.com
