[rules-users] Drools 6 - Trouble with newReaderResource(Reader reader)

[Markus Schneider]

Hi list,

try to make my first experiences with Drools 6. For that purpose I've
modified slightly the 'KieFileSystemExample'
(
https://github.com/droolsjbpm/drools/blob/6.0.0.CR3/drools-examples-api/kiefilesystem-example/src/main/java/org/drools/example/api/kiefilesystem/KieFileSystemExample.java
)
as the code below shows. I try to use the newReaderResource(Reader reader)
but when I run maven test I get
the following error:

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.33 sec
<<< FAILURE! - in

public class KieFileSystemExample {

    public String getRule() {
        String s = "" +
                   "package org.drools.example.api.kiefilesystem \n\n" +
                   "import org.drools.example.api.kiefilesystem.Message
\n\n" +
                   "global java.io.PrintStream out \n\n" +
                   "rule \"rule 1\" when \n" +
                   " m : Message( ) \n" +
                   "then \n" +
                   " out.println( m.getName() + \": \" + m.getText() ); \n"
+
                   "end \n" +
                   "rule \"rule 2\" when \n" +
                   " Message( text == \"Hello, HAL. Do you read me, HAL?\"
) \n" +
                   "then \n" +
                   " insert( new Message(\"HAL\", \"Dave. I read you.\" )
); \n" +
                   "end";
        return s;
    }

    public void go(PrintStream out) {

        KieServices ks = KieServices.Factory.get();
        KieRepository kr = ks.getRepository();

        KieModule kModule =
kr.addKieModule(ks.getResources().newReaderResource( (Reader) new
StringReader(getRule()) ));

        KieContainer kContainer =
ks.newKieContainer(kModule.getReleaseId());
        KieSession kSession = kContainer.newKieSession();
        kSession.setGlobal("out", out);

        kSession.insert(new Message("Dave", "Hello, HAL. Do you read me,
HAL?"));
        kSession.fireAllRules();
    }

    public static void main(String[] args) {
        new KieFileSystemExample().go(System.out);
    }
}

Any Idea?

Thanks in advance.
