[jboss-user] [Beginners Corner] - ExpanderResolver was not set

[jackywong]

Dear all,

I have followed the livetrails at http://labs.jboss.com/file-access/default/members/jbossrules/freezone/livetrails/credit_dsl_viewlet_swf.html  but i'm stuck.

I get this error:

Exception in thread "main" java.lang.IllegalArgumentException: Unable to use expander. Make sure a expander or dsl config is being passed to the parser. [ExpanderResolver was not set].
	at org.drools.lang.RuleParser.expander(Unknown Source)

	at com.livetrail.CreditExample.main(CreditExample.java:26)


Anyone has encounter this same problem when going tru the live trails?

Please share your solution.
Thanks.
