DirPropertyBook

public abstract class PropertyBook
extends Task
implements java.lang.Runnable

Abstract class to implement to be a Property Book. Extends the Task interface so that property books can be launched like other tasks.

OutputData issue: In order to support both XSL and HTT in the name PropertyBook, this needs to support outputting data to either xml or properties. In the case of the frameset, menubar, and applybar we now these are currently implemented in htt, so we can output data directly to the resultStrings. However, when we are showing a page we do not now know if we will be showing an xml page or an htt page until after we call the previous page's cache method and the next page's show method (becuase one could throw an exception). Thus we output data using the outputData method. This creates a list of data items. This data is later put into the resultStrings or xml by calling the blastData method.

Moo limitations: Currently pages commit method does not get called if the writeData is being done on a seperate thread (which only happens in Moo - MultipleObjectOperations). The only way pages can participate in Moo is to through the PropertyBook.writeData method. For the DirPropertyBook this means using the MooManager object (NDSNamespace). This is a object specially designed to apply object operations to many eDirectory objects.

XML PropertyBook Params - things books can custimize by adding params to the install xml file.
Book.objectTypeDisplayNameKey urlparam displayName
Book.Icon.name urlparam icon on first page
Book.Icon.alt urlparam alt for icon on first page

eMFrameUtils.setMessage issue: these utilities output data directly to either the XML or Properties. The problem is that the PropertyBook doesn't know if the response will be XML or HTT when it calls this method.
