Improve the performance of your Java code: ON: 2007-08-02 09:42:40; Many algorithms are expressed most concisely as tail-recursive methods. Compilers can automatically transform such methods into loops and thereby improve program performance, but this transformation is not required by the Java language specification, so not all JVMs will perform it. This means that tail-recursive methods in the Java language can result in unexpectedly large memory usage. This article demonstrates that dynamic compilation maintains the language's semantics while static compilation often doesn't. Learn why this matters and get a bit of code to help you determine whether your just-in-time (JIT) compiler can transform tail recursion on code while preserving semantics.; 22 times | category: [Development]

What's new in JDBC 3.0: ON: 2007-08-01 10:24:52; The Java Database Connectivity (JDBC) API has emerged as a key part of the Java 2 Standard Edition (J2SE) and Java 2 Enterprise Edition (J2EE) platforms. It is the primary standards-based mechanism for the Java language to programmatically access relational databases, so when a new version of the specification is released by the Java Community Process, developers are bound to be interested. This article summarizes the key new features as outlined in Sun Microsystems' recently released Proposed Final Draft 3.0 of the JDBC specification.; 41 times | category: [Database Related]

JMS 1.1 simplifies messaging with unified domains: ON: 2007-08-01 10:18:26; JMS 1.1 unifies point-to-point and publish/subscribe domains, allowing developers to create more general, reusable messaging code. 1.0.2 API provides little support for an application using both domains together, and no support for developing reusable frameworks that can work equally well with destinations of either domain. JMS 1.1 fixes this shortcoming by unifying these domains. This article explores how much easier it is to develop JMS client code using the latest version.; 40 times | category: [Communication]

Developing and distributing Java applications for the client side: ON: 2007-08-01 10:12:24; Java Web Start, a new technology to assist the development of client-side Java applications, is unique in that it frees you from concerning yourself with how the client is launched, either from a Web browser or from the desktop. Additionally, this technology provides an encompassing deployment scheme that enables a Web server to independently distribute and update client code. This article introduces this enterprising new technology, which is scheduled to be integrated in the final release of Java 1.4, describing its implementation from both the developer and the user perspective.; 53 times | category: [Application Building]

Introducing inheritance to PropertyResourceBundles: ON: 2007-08-01 10:11:35; Creating a fully internationalized Java application using PropertyResourceBundles can present some interesting design and implementation problems, including concern over how to modularize the bundles to be used in different areas of the application. This article explores a solution based on PropertyResourceBundles, which should simplify the design and implementation problems, while promoting reuse of existing bundles.
