Where do I find information on adding a new tag in a java file(I am calling it @ejb:hash-object). The same way ant has predefined ejbdoclet subtask like <data-object/> I would like to use <hash-object/> for converting the data objects in a hash map..which can then be sent over to the client. Later I will also need to make it include only those attributes which are specified by another tag for attributes I want to be included in the hash map...and so on :-) I have a elementary template for testing and have HashObjectSubTask...to implement the subtask I need. However to test it I should be able to include a new tag and then have a subtask in the ejbdoclet task. Please let me know where to get more info on this. Thanks. -manish
