CDPN Really Warming Up! China Datacom Corp. Sym: CDPN Close: $0.0675 UP 4%
Investors are taking notice of CDPN, with hot news, volume rising, and price on a steady climb. This is is on the hot list. Get on CDPN first thing Tuesday! The first way involves the Observer and Observable classes found in the java. Here, Sun technology evangelist Rima Patel Sriganesh steps you through some best practices for designing applications that use the Java Persistence API. " I thought, "Hmm, that seems to map what's going on here. When you find something wrong, it's important to see if there's a matching bug report. Even if you don't find a solution, you'll learn and become a more powerful developer. In short, use the Singleton design pattern when you want to ensure that one, and only one, instance of a class is ever created. They will address such issues as license types, ways to mix and match licenses, contributor agreements, and methods to legally create products that combine open-source and proprietary components. 0-based applications. For example, you might discover that system performance is degrading because your program is repeatedly creating instances of the same class to pass along state information. The pattern is a behavioral design pattern. " Instead of helping one developer, leverage your work and help everyone. It hides the implementation details of the subclasses, allowing the factory to directly call the constructors for the interface implementations. Harry: Bug fixing is a great way to understand how the code works. You'll also have the chance to share your experiences and ideas with Conference attendees from all over the world. The Subject is what is observed. Attend this session and get the technical details on what's new in GlassFish v2, as presented by Sun staff Engineers Dhiru Pandey and Larry White. 0-based applications. Interoperability is a key issue to enterprise Java technology developers, and certainly many have hoped for application interoperability between the Java EE platform and Microsoft . However, developing these kind of services using the Java platform is significantly more complex than developing SOAP-based services. What motivates you to fix these bugs? You can also attend some good Seam-related BOFs: "Improve and Expand JavaServer Faces Technology With JBoss Seam" (BOF-4400), led by Michael Yuan of Red Hat Inc. org pavilion, dedicated to featuring open-source communities that are driving innovation. There is nothing technically wrong with the classes and they are still present in the libraries. Also, make sure that the test case is running on the event dispatch thread (EDT). Otherwise, by default, the system will provide a public constructor, something you don't want when working with a Singleton. Even if you don't find a solution, you'll learn and become a more powerful developer. The JButton doesn't care what class the attached Observer (listener) is. addActionListener(listener); That really is all there is to the Observer pattern for the system-defined classes. The Java API for RESTful web services (JSR 311) is designed to simplify the development of REST-based services using the Java platform. It was my first time using it, and I was very pleased with it. See if you can find why something started. It presents no fewer than 30 Java technology-based open-source projects, providing code examples and small demos for each of them. Phipps also joins Apache's Cliff Schmidt and Eben Moglen of the Free Software Foundation for a panel discussion on open-source licensing. Recent work in Seam has focused on bringing this same programming model to service-oriented architecture (SOA) environments.
