Using Aspect-Oriented Programming to Maintain Legacy Java Apps
|
|
|
In an enterprise environment, you can easily end up in a tangle of modules with a number of third-party libraries and frameworks. While a number of tools are available to aid you in comprehending complex programs, most are expensive and time-consuming to learn. Aspect-oriented programming can be applied to a wide range of programming scenarios, including the comprehension and maintenance of legacy applications.

Introducing the Reflexive User Interface Builder
|
|
|
The IBM Reflexive User Interface Builder (RIB), a new technology available from alphaWorks, is an application and toolkit for building and rendering Java AWT/Swing and Eclipse SWT GUIs. RIB specifies a flexible and easy-to-use XML markup language for describing Java GUIs and provides an engine for creating them. You can use RIB to test and evaluate basic GUI layout and functionality, or to create and render GUIs for an application.

Data Management in J2EE Apps
|
|
|
This article examines two data management strategies available on the Java platform: Java object serialization and Java Database Connectivity (JDBC). While neither data management strategy is inherently superior or inferior to the other, when it comes to managing enterprise information systems, JDBC wins hands down.

Threading lightly : Reducing contention
|
|
|
While its common to hear that synchronized method calls can be 50 times as expensive as unsynchronized method calls, these numbers can actually be quite misleading. With each successive JVM version, overall performance has improved, and the cost of uncontended synchronization has been reduced, making the issue of uncontended synchronization overhead less significant. Contended synchronization, however, is quite expensive. Moreover, a high degree of contention is disastrous for scalability -- an application that had a high degree of contended synchronization will exhibit markedly worse performance as the load increases. This article explores several techniques for reducing contention, and hence improving scalability, in your programs.

Concurrency in JDK 5.0 Tutorial
|
|
|
JDK 5.0 added major new support for developing concurrent applications, including JVM changes, new low-level synchronization utilities, and higher-level, thread-safe, high-performance concurrency classes such as thread pools, concurrent collections, semaphores, latches, and barriers. Learn how these new classes can help make your code faster, more scalable, more reliable, and easier to maintain.
