Most Java programmers use some kind of tracing system to keep track of potential errors and problems in code under development. However, multithreaded and multiplatform systems can generate a large and baffling amount of tracing data. This article offers tips that will help you make sense of trace data from complex applications.
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.
People who aren't familiar with XP are bothered by the concept of just-in-time (JIT) design -- designing and implementing what you know you need right now and not worrying about future design issues until absolutely necessary. While this approach might seem unwise or even reckless, XP advocate Roy Miller wraps up his series by showing you how safe and easy JIT design is -- and how it just might revolutionize the way you write code.
As the J2EE platform has matured, it has opened up the opportunity to deploy commodity servers in networked cluster configurations for scaling of Web services and Web applications at the Web tier. These commodity servers, interconnected through commodity LAN hardware, can provide cost-effective clustering solutions. The last piece of the clustering puzzle is in the software. In this seriesSing Li examines three open source software substrates that can enable high-impact Web tier clustering, beginning with JavaGroups.
This article discusses incremental compaction, a new feature in the memory management component of IBM JDK 1.4.0. Incremental compaction is a way of spreading compaction work across different garbage collection cycles, thereby reducing pause times. The authors discuss the need for incremental compaction, the compaction phases at a high level, and some runtime parameters. They also explain how to interpret changes in the verbosegc output.
Love or hate it, static type checking can make code more robust. Programming languages are moving away from static type checking, but it is too powerful a debug resource to abandon. Static type checking can be one of the key weapons in a powerful arsenal against introducing and for detecting bugs. This article explains why we should be glad that the Java language supports it, and discusses how it can be made even better.
Every Java programmer should be aware of the problem of code pages vs. Java Unicode. This article describes some pitfalls to avoid with code page and Unicode conversions and provides example fixes for the problems. Armed with this informaion, you should be able to create applications that are more truly platform and code page independent.
Learn the pros and cons of generating native code from Java source. This article includes the
basics of code compilation, including a brief overview of why many developers are employing Java
native compilers for their applications.
Ejb was introduced to Java technology to attain some features inherent in enterprise applications. Those features include instance pooling, inbuilt security, declarative transactions, container managed persistence, relationship of business objects and caching etc. Now that many people have built their applications using Ejb, let us go back and analyze if Ejb as a technology is really significant in developing enterprise applications. We are going to analyze both pros and cons of Ejb based on experience of people who have used Ejb.
