<div dir="ltr">Thanks Wolfgand Laun. Finally it worked. It was indeed a translation error as the VM was not able to find the DSL file. I changed the content as suggested, included an expander statement and it worked fine.<br>

The corrected version of dsl and dslr works fine.

<br><br>You don't have to write the DSL all in one line. (I fixed that some time ago.)
<br><br>The error message suggests that translation fails.
<br>1) Make sure the DSLR is *exactly* as above. (The package could be
<br>different, and there is tolerance w.r.t. spacing between words.)
<br>2) ALWAYS print builder errors (see below).
<br>3) Make sure you pass resources correctly to the builder. This is how
<br>it is done for 5.x:
<br><br> KnowledgeBaseConfiguration kBaseConfig =
<br> KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
<br> KnowledgeBuilderConfiguration kbConfig =
<br> KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();
<br> KnowledgeBuilder kBuilder =
<br> KnowledgeBuilderFactory.newKnowledgeBuilder( kbConfig );
<br><br> Resource dsl = ResourceFactory.newFileResource( dslPath );
<br> Resource dslr = ResourceFactory.newFileResource( dslrPath );
<br> long t0 = System.currentTimeMillis();
<br> kBuilder.add( dsl, ResourceType.DSL );
<br> kBuilder.add( dslr, ResourceType.DSLR );
<br> if( kBuilder.hasErrors() ){
<br> System.err.println( ">>> compilation errors >>>" );
<br> KnowledgeBuilderErrors errors = kBuilder.getErrors();
<br> for( KnowledgeBuilderError err: errors ){
<br> System.err.println( err.getMessage() );
<br> }
<br> System.err.println( "<<< compilation errors <<<" );
<br> throw new IllegalStateException( "compile errors" );
<br> }
<br> kBase = KnowledgeBaseFactory.newKnowledgeBase( kBaseConfig );
<br> kBase.addKnowledgePackages( kBuilder.getKnowledgePackages() );
<br> kSession = kBase.newStatefulKnowledgeSession();
