GWT 项目开发 1.6.4 本地开发 appengine-tools-api 突破限制
经过研究发现。google 的限制jar 是
?
appengine-tools-api?
?
修改类：
?
com.google.appengine.tools.development.DevAppServerFactory
?
就可以再本地环境适应 hibernate 连接数据库。创建线程，创建文件等操作。(当然你改的是本地环境。google服务器上的是没有办法了。）
?
这样做主要是为了开发 gwt 应用的。
?
修改类如下：

附件是?appengine-java-sdk-1.6.4\lib\appengine-tools-api.jar 的jar包。替换就可以了。
?
jar 文件大于 10 MB 所以压缩了下。解压缩再替换。
