程序我就不贴出来了 就是最简单的hello world 。
我以前也建过类似的测试程序，在Eclipse下直接 run as --》 java application 都行的 今天突然就报错了，估计是Eclipse的原因。 我在命令行下是可以运行的

------解决方案--------------------
E:\workspace_wap\WAP\BIOP_WAP\components\wapServiceServer
路径换过吧？
------解决方案--------------------
新建workspace试试？
------解决方案--------------------
找到 C:\google\appengine-java-sdk-1.3.1\config\user\ant-macros.xml
将line 102
<fileset dir="@{war}/WEB-INF/classes" includes="**/*.class"/>
改为
<fileset dir="@{war}/WEB-INF/classes" includes="**/*JDO.class"/>
