JAXB moxy错误：通过属性映射处理外部元数据时遇到无效的参数类型

Question

I followed this example to implement moxy in my project. However I am getting the following error and have not been able to find a solution yet.

   Exception in thread "main" Local Exception Stack: 
   Exception [EclipseLink-50019] (Eclipse Persistence Services - 2.0.2.v20100323-r6872): org.eclipse.persistence.exceptions.JAXBException
   Exception Description: Invalid parameter type encountered while processing external metadata via properties Map.  The Value associated with Key [eclipselink-oxm-xml] is required to be one of [Map<String, Source>], where String = package, Source = handle to metadata file.

I am new to jaxb and moxy, any help towards getting my moxy setup is appreciated.

Use instance of Source, it is in the error message:

 Value associated with Key [eclipselink-oxm-xml] is required to be one of [Map<String, Source>], where String = package, Source = handle to metadata file.

example:

 ... 
 javax.xml.transform.Source source = 
   new javax.xml.transform.stream.StreamSource("mypackage-metadata.xml") 
 map.put("example.mypackage", source);
 ...
