I start a process by session and set a map of parameters.The name of a parameter is "person". As follows: KnowledgeBuilder kBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kBuilder.add(ResourceFactory.newClassPathResource("hello.bpmn"),                 ResourceType.BPMN2); KnowledgeBase kBase = kBuilder.newKnowledgeBase(); StatefulKnowledgeSession kSession = kBase.newStatefulKnowledgeSession(); Map<String, Object> params = new HashMap<String, Object>();    Person person = new Person(); person.setName("martin"); params.put("person", person); ProcessInstance pInstance = kSession.startProcess("com.sample.hello", params); then I think print the name of person in a script action.Code as follows: System.out.println(person.getName()); I run my codes and then get a exception: [main] ERROR builder.impl.KnowledgeBuilderImpl.newKnowledgeBase  - Process Compilation error : org.drools.lang.descr.ProcessDescr@79024994     defaultPackage/Process_defaultPackage_Sample_Process_4419562b234b4de3b32f940de6602c9f.java (11:468) : person cannot be resolved Exception in thread "main" java.lang.IllegalArgumentException: Could not parse knowledge.     at org.drools.builder.impl.KnowledgeBuilderImpl.newKnowledgeBase(KnowledgeBuilderImpl.java:79)     at com.sample.JBPMTest.main(JBPMTest.java:23) How to get parameters in script action?
