I've managed to deploy JBoss Rules using Seam quite happily, going along with the docs, but as soon as I try and use a Domain Specific Langage file (.dsl) things come apart:
My components.xml has this: <component name="myRules" | class="org.jboss.seam.drools.RuleBase"> | <property name="ruleFiles">drools/myrules.drl</property> | </component> | <component name="myWorkingMemory" | class="org.jboss.seam.drools.ManagedWorkingMemory"> | <property name="ruleBaseName">myRules</property> | </component> I deploy my application EAR with both files (myrules.drl and myrules.dsl) inside the drools dir, i.e. application.ear/drools/ The myrules.drl defines the DSL thus: package com.example.myapp | | expander myrules.dsl | | rule "My Rule" | ... etc etc It works fine in Eclipse, but when I try and use it in my app: public class MyActionImpl implements MyAction { | | @In(create=true) | WorkingMemory myWorkingMemory; | | public void doAction() { | .... | myWorkingMemory.assertObject(myObject); | myWorkingMemory.fireAllRules(); | .... | } I get the following exception: java.lang.IllegalArgumentException: Unable to use expander. Make sure a expander or dsl config is being passed to the parser.

Or does this just not work at this stage?
