无法找到NamespaceHandler核心

Question

org.mule.api.lifecycle.InitialisationException: Initialisation Failure: Configuration problem: Unable to locate NamespaceHandler for namespace [http://www.mulesource.org/schema/mule/core/2.1] 
Offending resource: URL [file:/D:/School/EAD/CourseSVN/bart/EA3/conf/dare2date-config.xml] 

我知道你必须添加你需要的东西来骡子的类路径，但它怎么能不能处理核心？

我的配置：

Answer 1

解决办法很简单，我没有2.1版本（但2.2或东西）。
