Query: Same as online documentation - save your money

I have been using and developing htmldb (or application express) applications for the past 8 months. I needed something more than the online documentation, such as creating custom reports that go well beyond those available in the Oracle documentation or, for example, using FCK Editor as an HTML editor for text areas, or issues related to uploading and downloading of documents using html db. This book is a total repeat of the online users guide and 2-day dba. You can print the 2-day dba, 2-day developers guide and the users guide and you will get far more useful information than in this guide. This guide contains very little additional information from the documentation that comes with application express. What a total waste of money.
