远程api GAE/J: StackOverflowError？

Question

我正在尝试从另一个GAE/J应用程序查询我的一个GAE/J应用程序的数据存储，但我在使用开发服务器时遇到了这个错误，而且在生产中也是如此

/servlet_url的错误

在多次远程请求之后检查第一个应用程序的appstats时，我看到有几个成功的/remote_api查询，但没有RPC调用

*2011-11-02 23:22:59.298 "GET remote_api“200 real=0ms cpu=0ms api=0ms overhead=0ms (0 RPC)*

PS:我严格遵循了这里描述的步骤：http://code.google.com/intl/fr-FR/appengine/docs/java/tools/remoteapi.html
