[rules-users] ClassCastException in JBoss 4.2.2

[David Norwood]

Hi, all of a sudden this error shows up. So, I upgrade from 4.0.4 to 4.0.7,
and the issue is still there. Some posts mention this may be related to the
JDT. Do I need to have JDT in my path? Another post said to add the
-Ddrools.compiler=JANINO as a Sys prop, which doesn't fix the problem
either.

Help?

Code is here:

	private RuleFactory() {
		bases = new HashMap();
		dsls = new HashMap();
		packages = new HashMap();
		conf = new PackageBuilderConfiguration();   <----- error happens here
/*		JavaDialectConfiguration jConf = (JavaDialectConfiguration) 
			conf.getDialectConfiguration( "java" );
		jConf.setCompiler( JavaDialectConfiguration.JANINO );  
		//conf.setJavaLanguageLevel( "1.5" );
		conf.setCompiler( PackageBuilderConfiguration. ); */
	}



And error here:
