Hi everybody, I try to run a simple DSL example. My DRL is as follows: package org.mydrools.examples #must be in the following order. import org.mydrools.examples.Person import org.mydrools.examples.Cheese #refer to test_expander.dsl expander test_expander.dsl rule "my rule" when #Person(name=="Dani", likes=="maroilles") #Cheese(type=="maroilles") There is a person with the name of Dani who likes maroilles There is some maroilles cheese available then Add the message "We have a winner" #System.out.println("We have a winner"); end My DSL is as follow: #some description [when]There is a person with the name of {name} who likes {cheese}=Person(name=="{name}", likes=="{cheese}") [when]There is some {cheese} cheese available=Cheese(type=="{cheese}") [then]Add the message {message}=System.out.println({message}); [when]person with eval=p : Person() eval(p.getName().equals("fire")) And I load them as below: kbuilder.add(ResourceFactory.newClassPathResource("test_expander.dsl"),ResourceType.DSL); kbuilder.add(ResourceFactory.newClassPathResource("Sample.drl"), ResourceType.DRL); The following error messages appear: [8,9]: [ERR 101] Line 8:9 no viable alternative at input 'test_expander' in rule expander [11,0]: [ERR 101] Line 11:0 no viable alternative at input 'rule' in rule expander in rule dsl [15,2]: [ERR 101] Line 15:2 no viable alternative at input 'There' in rule expander in rule dsl in rule "my rule" Any idea ?

Thanks. I am using the latest up-to-date Drools 5.1. I have  changed  DSL to DSLR. Whatever I include or not the expander in the DRL file, I have the following error message: [2,0]: [ERR 101] Line 2:0 no viable alternative at input '[' [8,0]: [ERR 103] Line 8:0 rule 'rule_key' failed predicate: {(validateIdentifierKey(DroolsSoftKeywords.RULE))}? in rule 15,2]: [ERR 101] Line 15:2 no viable alternative at input 'There' in rule "my rule" This example is included in drools-compiler in (integrationtests), but it seems that I miss something. Your help will be appreciated on this. Best, MM. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Simple-DSL-example-tp...
