javax.activation.URLDataSource
The URLDataSource class provides an object that wraps a URL object in a DataSource interface. URLDataSource simplifies the handling of data described by URLs within the JavaBeans Activation Framework because this class can be used to create new DataHandlers. NOTE: The DataHandler object creates a URLDataSource internally, when it is constructed with a URL.

method on the URL. If this method fails, or if a content type is not
returned from the URLConnection, getContentType returns
application/octet-stream as the content type.
returns: the content type. - java.lang.String
