[rules-users] Knowledge Builder Question

[Fnu Mahalakshmi]

Hi guys,

In my program I have couple of .brl, .drl and .dslr files which get added to the rulebase.

Now my .brl files get converted to drl files and then have to be added to the rulebase.

After creating my .drl or .dslr file I am using this code to update the resources in my change-set.xml
ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty( "drools.resource.scanner.interval",
                   "30" ); // set the disk scanning interval to 30s, default is 60s
ResourceFactory.getResourceChangeScannerService().configure( sconf );
ResourceFactory.getResourceChangeNotifierService().start();
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add( ResourceFactory.newClassPathResource( "change-set.xml", getClass()),ResourceType.CHANGE_SET );
if ( kbuilder.hasErrors() ) {
   System.err.println( kbuilder.getErrors().toString() );
}

Now as per my understanding:
Since a new .drl file has been just created - the resource notifier will update my change-set.xml file of the change.

Now I need to load this new file to my rulebase along with my dsl file.

kbuilder.add( ResourceFactory.newClassPathResource( "change-set.xml", getClass()),ResourceType.CHANGE_SET );

is adding my new created file to my knowledge pacakage.
How can I specify my dsl file also to be added along with it???

I also keep getting the following error when I run the program:

Exception in thread "main" java.lang.NoSuchMethodError: org.drools.compiler.PackageBuilder.addKnowledgeResource(Lorg/drools/io/Resource;Lorg/drools/builder/ResourceType;Lorg/drools/builder/ResourceConfiguration;)V
      at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:30)
      at com.org.RuleRunner.loadRules(RuleRunner.java:75)
      at com.org.RuleRunner.runStatelessRules(RuleRunner.java:155)
      at com.org.RulesTest.main(RulesTest.java:40)
Is my drools-compiler.jar not having the correct information required???? How can I change that??

Can you please guide me in the right direction..??
Please help.

Thank you.
M
