我试着让这个样本运行http://wiki.restlet.org/docs_2.0/13-restlet/275-restlet/252-restlet.html但是一旦我启动它，我收到这条消息，遗憾的是我什么都不知道。

我使用Eclipse 3.7，“使用”GWT（3）2.4“和”App Engine（4）1.6.0“创建Web应用程序项目”

我有什么必须进入的地方，有人可以帮助我吗？

Thanx Bobert

Answer 1

您尝试在DevMode中启动GWT应用程序，但Eclipse中的“运行配置”不正确。这是“运行配置”中的参数应如下所示的示例：

-server com.google.appengine.tools.development.gwt.AppEngineLauncher -remoteUI“$ {gwt_remote_ui_server_port}：$ {unique_id}”-startupUrl index.html -logLevel INFO -war / home / koen / workspace / klawt / war -codeServerPort 9997 -port 8888 com.example.MyModuleEntryPoint

这是您遗失的最后一个参数：com.example.MyModule。您必须在com.example包中有相应的MyModule.gwt.xml。

Answer 2

IIRC版本需要完全正确。

就像我使用的是Restlet 2.1和GAE 1.5.2。

另请注意，Restlet 2.0支持1.4.2。

GAE Restlet示例“缺少必需参数”
