Plug memory leaks in enterprise Java applications
Because Java uses automatic garbage collection, developers think
Java programs are free from possible memory leaks. Although
automatic garbage collection solves the main cause of memory leaks,
they can remain in a Java program. Specifically, such memory leaks
in complex multitiered applications can be extremely daunting to
detect and plug. This article analyzes the main causes of memory
leaks in Java Enterprise Edition (Java EE) applications, and
suggests strategies for detecting them.

Learn to speak Jamaican
Jamaica, the JVM Macro Assembler, is an easy-to-use assembly
language for JVM bytecode programming. It uses Java syntax to
define a JVM class, and, in method bodies, it takes bytecode
instructions and Jamaica's built-in macros. All of Jamaica's
bytecode instructions use mnemonics and symbolic names for
variables, parameters, data fields, constants, and labels. Jamaica
macros make JVM assembly programs shorter and easier to read.
Internally, Jamaica uses a Java API, JavaClassCreator, to create
Java classes. This API is much more abstract than low-level APIs
such as ASM and the Byte Code Engineering Library (BCEL). It
closely mimics the Jamaica language, allows users to define a Java
class with the same flow, and supports all the Jamaica instructions
and macros. The JavaClassCreator API currently supports
implementations atop the ASM and BCEL. Creating JVM classes at
bytecode level is risky and error-prone. Jamaica allows you to
quickly experiment dynamically with creating Java classes; once
complete, you can mechanically convert the Jamaica source code into
JavaClassCreator API calls. This article introduces you to the
convenience of the Jamaica language.

Profiling the profilers
Who doesn't have some performance problems in their Java
applications? Let's be honest...all of us do. Code profilers are
the only custom tools designed to tackle this universal problem. In
this article, Laurence Vanhelsuwé reviews three commercial
Java profilers: Borland's Optimizeit Suite, Quest Software's JProbe
Suite, and ej-technologies' JProfiler.
