Hello, I try to use a dsl in several DRL rule files, but it doesn't work. In my java class, I do that : Reader source1 = new InputStreamReader( DroolsTest.class.getResourceAsStream( "/Test1.drl" ) ); Reader source2 = new InputStreamReader( DroolsTest.class.getResourceAsStream( "/Test2.drl" ) ); //optionally read in the DSL (if you are using it). Reader dsl = new InputStreamReader( DroolsTest.class.getResourceAsStream( "/Exemple.dsl" ) ); builder.addPackageFromDrl( source1, dsl ); builder.addPackageFromDrl( source2, dsl ); Is it possible to use a same dsl file in several drl files or I have to have one dsl for one drl ? Thanks :-) -- View this message in context: http://www.nabble.com/using-a-dsl-in-multiple-drl-files-tp21584358p215843... Sent from the drools - user mailing list archive at Nabble.com.
