Advertisements provide a platform independent representation of core platform objects that can be exchanged between different platform implementations (Java, C, etc.). <p>Each Advertisement holds a document that represents the advertisement. Advertisements are typically represented as a text document (XML). The <A HREF="../../../net/jxta/document/Advertisement.html#getDocument(net.jxta.document.MimeMediaType)"><CODE>getDocument(mimetype)</CODE></A> method is used to generate representations of the advertisement. Different representations are available via mime type selection.
