更新到java 6u31后,DevServer失败

Question

这是我收到的错误.当我恢复使用6u30时,它工作正常.现在必须更新AppEngine来修复此错误.

Answer 1

这是一个众所周知的错误:http://code.google.com/p/googleappengine/issues/detail？ id = 6928

解决方法是将此行添加到运行配置中:

-Dappengine.user.timezone=UTC

对某些人来说,它一定是:

-Dappengine.user.timezone.impl=UTC

如果包括GWT,后者似乎有效; 如果你不使用GWT和GAE,那么使用前者.

Answer 2

由于这是之前所说的-下载应用程序引擎从这个网址为Java 1.6.3.1:http://code.google.com/appengine/downloads.html 然后把它解压到某个文件夹,然后去到Eclipse中,选择窗口- >首选项- > Google - > App Engine - >添加并查找包含下载文件的文件夹.确保将新版本检查为活动状态并单击"确定"后.这个解决方案对我有用.
