Developers: Learn About Emerging Technologies from OTN
If you're a Java developer, the continual and bewildering array of emerging new technologies can keep you permanently off balance. In fact, it may seem that there is not enough time or training in the world to keep your skill set up to date.
Recently OTN has taken explicit steps to ensure that you have easy access to free technical information and resources about evolving specifications such as Enterprise JavaBeans (EJB) 3.0, JavaServer Faces (JSF), and Business Process Execution Language (BPEL), aspects of which are increasingly supported in Oracle middleware, development tools, and frameworks.
First of all, we've made broadband versions of Oracle Developer Day presentations from the "Developing Service-Oriented Architecture" (SOA) track available online; topics include "Constructing the Services Layer with EJB 3.0" and "User Interfaces with SOA." You'll find these presentations invaluable for an overview of SOA.
Second, thanks to the efforts of Oracle JDeveloper team members such as Christian Schalk, Duncan Mills, and Raghu Kodali, you can now access sample code, software downloads, how-tos, and tutorials associated with emerging technologies such as the aforementioned EJB 3.0, JSF, and BPEL from dedicated Web pages. For example, on the EJB 3.0 page, you'll find hands-on resources for developing your first Entity, Message-Driven, and Session Beans and for testing EJBs outside the container.

Explore New Hosted Services
OTN has made new hosted Web services available for developers who want to explore the capabilities of Web services in a "live" environment. We've published a series of Web pages for that purpose; each contains Web Service Description Language (WSDL) documents as well as downloads of the binaries required for creating your own client applications.
At the time of this writing, options included a "Hello, World" service providing several operations that return simple string responses, a Global Unique Identifier service, and an Employee Query service that provides access to departmental and employee information in a database.
