Eclipse in Action: A Guide for the Java Developer by Robert McGovern [Repost]

Eclipse is a new open-source, Java-based, extensible development platform designed for nothing in particular but everything in general. Because of its roots, it is currently most popular as a Java integrated development environment (IDE). Eclipse ships with plugins for writing and debugging Java code. Additional plugins for more advanced Java development, such as JSP/servlets, are available from third parties.
