Value objects
Value objects are numbers, dates, strings, email addresses, isbn numbers, etc.. Value objects are usually small and simple, their identity is based on their state, not on the object identity. Since they are usually immutable they can be put into good use in optimization in conjunction with the flyweight pattern.

Recursive directory listings
A simple and yet troublesome for some, part of Java coding, is the ability to move recursively through directory structures. When processing directories full of files this is most definitely needed. We can accomplish this with a simple logic jump. We need to create a method to process all the files of a given directory, that when a directory is encountered calls itself passing in the new File that contains the directory.

JSP Tutorial For Beginners
JSP is part of the Java technology family. JSP technology is a key component in a highly scalable architecture for web-based applications. A JSP is translated into Java servlet before being run, and it processes HTTP requests and generates responses like any servlet. Like ASP or PHP, JSP also has dynamic scripting capability that works with HTML code, separating the web page logic from the static elements.

Exploiting ThreadLocal to enhance scalability
The ThreadLocal class appeared with little fanfare in version 1.2 of the Java platform. While support for thread-local variables has long been a part of many threading facilities, such as the Posix pthreads facility, the initial design of the Java Threads API lacked this useful feature. Further, the initial implementation was quite inefficient. For these reasons, ThreadLocal gets relatively little attention, but it can be very handy for simplifying the development of thread-safe concurrent programs. In this third installment of Threading lightly, Java software consultant Brian Goetz examines ThreadLocal and offers tips for exploiting its power.
