     摘要: 如果你是一名Java软件或Ajax开发者，可能Google Web Toolkit(GWT)已经引起了你的注意。
2006年5月，Google发布了这一免费的工具箱，遵循Apache风格的许可证。GWT被设计用于以Java语言编写Ajax应用。Google已经提供了Windows和Linux下的beta版本，并承诺以后增加Mac OS X版本。
本文描述了在Max OS X上一个简单的Ajax应用的开发，使用GWT和常用的Java工具，如Apache Ant，Tomcat 5.0 Servlet容器，以及IntelliJ IDEA集成开发环境（后者是一款商业IDE）。本文假设读者具有Java和Ant的基本知识。  阅读全文 Mastering EJB系列的第四版。深入介绍了EJB3.0带来的变化，包括Java persistence API以及如何在EJB中使用POJO实体。
