Drools运行异常1

1：Server returned HTTP response code: 401 for URL

需要启用验证

urlResource.setBasicAuthentication("enabled");
urlResource.setUsername("admin");
urlResource.setPassword("admin");

2：java.io.InvalidClassException: org.drools.rule.MVELDialectRuntimeData; local class incompatible: stream classdesc

原因是版本问题。

String path = "http://localhost:8080/guvnor-distribution-wars-5.4.0-20120516-jboss-as-7.0/org.drools.guvnor.Guvnor/package/com.sample/LATEST";
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
UrlResource urlResource = (UrlResource) ResourceFactory.newUrlResource(path);
urlResource.setBasicAuthentication("enabled");
urlResource.setUsername("admin");
urlResource.setPassword("admin");
kbuilder.add(urlResource, ResourceType.PKG);

 Guvnor版本是5.4.0的，在java中调用引用的版本是5.5.0的。把引用版本改为5.4的jar包就可以了
