Summary

The world has moved to Java and other component technologies. And now, for the first time, application developers are able to build robust Internet applications with reusable JavaBean components. Enterprise Java Developer's Guide is the first book that introduces all three phases of constructing an application with JavaBean component technology. In a single reference, you'll learn the foundations of component technology, how to develop reusable components, and then how to build applications using those components.
