Is there any way to get Drools flow to use the GroovyClassLoader to load Groovy classes?  I am trying the following unsuccessfully.

Setting the GroovyClassLoader

GroovyClassLoader gcl = new GroovyClassLoader();

gcl.addClasspath("c:\\temp\\");  //the  com.datacert.apps.sampleapplication.models.Person  Groovy class is in c:\temp

KnowledgeBuilderConfiguration conf = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(null, gcl);

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(conf);

Flow Definition

RuleFlowProcessFactory factory = RuleFlowProcessFactory.createProcess(_processName);

int nodeCount = 1;

factory.name("Migration Approval Flow").version("1.0").packageName("com.datacert").variable("entity",

                new ObjectDataType("com.datacert.apps.sampleapplication.models.Person")).variable("entityId",

                new ObjectDataType(String.class.getCanonicalName())).variable("currentApproverName",
