好消息：GAE开始支持java，GWT1.6发布，而且有了Google Eclipse插件

现在到 Google Web Toolkit (GWT)提供的下载已经是1.6版本了，更令人兴奋的是GAE开始支持Java了，请看App Engine Java Overview 。


Welcome to Google App Engine for Java! With App Engine, you can build web applications using standard Java technologies and run them on Google's scalable infrastructure. The Java environment provides a Java 6 JVM, a Java Servlets interface, and support for standard interfaces to the App Engine scalable datastore and services, such as JDO, JPA, JavaMail, and JCache. Standards support makes developing your application easy and familiar, and also makes porting your application to and from your own servlet environment straightforward.

现在可以一起使用GWT和GAE，而你只需要使用一种语言——java！而且google还提供了一个eclipse的插件 。

Spring的blog上也发布了一篇使用groovy开发GAE的文章——Write your Google App Engine applications in Groovy 。
