     摘要: 如果你是一名Java軟件或Ajax開發者，可能Google Web Toolkit(GWT)已經引起了你的注意。
2006年5月，Google發布了這一免費的工具箱，遵循Apache風格的許可證。GWT被設計用于以Java語言編寫Ajax應用。Google已經提供了Windows和Linux下的beta版本，并承諾以后增加Mac OS X版本。
本文描述了在Max OS X上一個簡單的Ajax應用的開發，使用GWT和常用的Java工具，如Apache Ant，Tomcat 5.0 Servlet容器，以及IntelliJ IDEA集成開發環境（后者是一款商業IDE）。本文假設讀者具有Java和Ant的基本知識。  閱讀全文 Mastering EJB系列的第四版。深入介紹了EJB3.0帶來的變化，包括Java persistence API以及如何在EJB中使用POJO實體。
