Bitter Java is a book about common Java programming traps (called anti-patterns), their causes and resolutions. Anti-patterns for server side Java programming and architecture are the focus. It is intended for intermediate Java programmers, analysts and architects. The book covers anti-patterns for J2EE concepts such as servlets, JSPs, EJBs, enterprise connection models, and scalability. There is a popular movement to capture positive design patterns, and an extensive library of design pattern books. Negative designs, sometimes called anti-patterns, are harder to find, but illustrate good programming practices much more graphically than design patterns. Anti-patterns have another benefit: they are fun. Bitter Java will explore some basic anti-patterns and introduce intermediate to advanced techniques in clear and entertaining language. The book will feature code samples sprinkled throughout the book, and real-life metaphors that are unrelated to programming. The examples are refactored into solutions that work, and are available on a web site for immediate download and use.
