Security was, is, and will be one of the most important aspects of Enterprise Applications and one of the most challenging areas for architects, developers, and administrators. It is mandatory for Java EE application developers to secure their enterprise applications using Glassfish security features.

Java Data Objects is a standardized Java API for object persistence. It facilitates the storage and retrieval of complex object models with various storage mechanisms, including both object and relational databases. Analysts agree that JDO's transparent persistence will accelerate software development and yield more flexible applications and object models.

.NET for Java Developers explains the .NET Framework from a Java programmer's perspective. Java has become such a popular language partly because it makes web-based rapid application development possible on different platforms. For Windows applications, however, Java has not been able to utilize all the platform-specific features that are available to Visual Basic and Visual C++. C# is the perfect solution. The similarities between Java and C# offer a channel for Java programmers to reuse their skills on the Windows platform.

Developing complex software requires more than just churning out lines of code. As a software architect or developer involved in an industrial project, you must understand and be able to leverage critical software sub-disciplines such as architecture, analysis and design techniques, development process, visual modeling, and the underlying technology to be successful.

Here's a unique, Java-centric guide to creating abstract data types, one of the main tenets of object-oriented programming and a key component in large-scale software development.
