Master J2ME for live data delivery The biggest challenge in building J2ME applications is creating a workable architecture that can span the wide range of wireless devices and protocols. This is especially true of applications that need to push live data to the client. This article explains some key design points... |

US Department of Energy signs on to J2EE If you architect many secure Web applications, authentication and authorization are always important concerns. Defining an architecture so that users can sign on to many n-tier Web applications only once---regardless of who built the applications, when they were built, or what kind of OSs and application servers they run on---is always a big challenge. This article presents a single sign-on architecture. |

A J2EE presentation pattern: Applets with servlets and XML Sometimes a standard HTML view on your J2EE-based system doesn't offer a sophisticated enough user interface. Based on the pattern described here, you can enhance such a Web interface with the Java Plug-in. The Java Plug-in lets you embed applets that consume XML documents and display the contained data in a particular way. These XML documents contain presentation data derived from servlets looking at your business logic tier. This lets your users access powerful UI components while still retaining a strong decoupling between the business logic and presentation tiers---without complicated firewall issues. |

Is WSDL the indispensable API? Many developers consider Web Services Description Language (WSDL) the new software design view. WSDL offers a verbose, ASCII, standard, and language-agnostic view of services offered to clients. WSDL also provides noninvasive future-proofing for existing applications and services and allows interoperability across the various programming paradigms, including CORBA, J2EE, and .Net. This article shows a service's WSDL view, then explains how you can generate client and service implementations for Java and C#. It finishes by discussing possible sources for initial WSDL view generation. |

Eliminate JDBC overhead Most J2EE and other types of Java applications interact in some way with information persisted in a database. Interfacing with that database involves several iterations of SQL statements, connection management, transaction lifecycles, result processing, and exception handling. The many parts of this ritualistic dance are common in all contexts; however, this replication doesn't have to exist. This article outlines a flexible framework that remedies the repetition of interacting with a JDBC-compliant database. |
