「初始化失敗」，同時部署GAE應用

Question

在部署GAE應用程序，我得到這樣的錯誤：

Uncaught exception from servlet 
javax.servlet.UnavailableException: Initialization failed. 
    at com.google.apphosting.runtime.jetty.AppVersionHandlerMap.createHandler(AppVersionHandlerMap.java:211) 
    at com.google.apphosting.runtime.jetty.AppVersionHandlerMap.getHandler(AppVersionHandlerMap.java:171)

    at com.google.apphosting.runtime.ThreadGroupPool$PoolEntry.run(ThreadGroupPool.java:162) 
    at java.lang.Thread.run(Thread.java:679) 

什麼會是什麼原因呢？

這可能是由於您的servlet失敗其方法init引起的。在這之前應該有另外一個堆棧跟蹤，其中有更多細節。
