I just made use of the very cool OTN Virtual Developer Day Database site. In this environment you can follow OTN Developer Day sessions, for example, at home, while making use of all the material available on that site plus the downloadable Virtualbox OTN Developer Day Appliance. Despite you can choose for tracks like Java, .Net, APEX, there is also a database section which handles (as you might expect it from me regarding interest) Oracle XMLDB functionality.
There is a 1 hour webcast available from Mark Drake, Oracle Product Manager, that takes you along all the basics / general overview (basic due too it is too extensive to show it in only an hour) of possibilities of Oracle XMLDB functionality. For convenience there is also a PDF document that has most of the slide info of the webcast. It doesn’t contain the demo’s or extra Virtualbox OTN Developer Day Appliance first steps info, of course, and what to do to reset the training XMLDB environment in this appliance.
This PDF and the webcast starts with the Oracle safeguard (legal disclaimer), with the general product outline slide saying among others that Oracle is not responsible or obliged to actually build-in features More >
While preparing for the new SOA for Java Professionals training program at AMIS, I was recently working on a section discussing XQuery and more specifically the ability to use XQuery from Java as an alternative to JAXB binding to POJOs on the one hand and DOM based XPath searches on the other.
The XQJ API for XQuery support from Java is relatively new and unknown. Implementations of the API are not yet part of Java 6 SE (I am not sure about Java 7) and the number of resources on the internet is still limited.
This article shows the steps for running a simple Java program for inspecting an RSS feed and printing titles for RSS items that concern Java. It also shows how to configure a Java application in JDeveloper 11g using the Oracle XDK implementation of XQJ.
