Question

当我点击在netbeans中的谷歌应用引擎上部署应用程序时，这些是产生的错误消息。让我告诉你，最初，我输入的密码错误，应用程序无法部署。但现在当我点击部署应用程序时，它不会问我电子邮件或密码。

无论如何我如何解决这些错误？

编辑： 我在linux中尝试了同样的事情，这次我输入了正确的密码。然后我也得到了以下例外：

Answer 1

以@alex所说的为基础......

您有第一个错误日志

Bad configuration: appengine-web.xml does not contain a <threadsafe> element. See http://code.google.com/appengine/docs/java/config/appconfig.html#Using_Concurrent_Requests for more information.

第一行

Bad configuration: appengine-web.xml does not contain a <threadsafe> element.

告诉你什么是错的。第二行

See http://code.google.com/appengine/docs/java/config/appconfig.html#Using_Concurrent_Requests for more information.

表示要解决问题的GAE文档的哪一部分。

我必须承认，错误日志条目非常明确且有用。我希望更多可以按照这里为你做的例子。如果你仍然被卡住了，请你准确说明你所坚持的内容吗？

Answer 2

只需在您的战争/ WEB-INF / appengine-web.xml中添加

<threadsafe>true</threadsafe>

像这样：

    <?xml version="1.0" encoding="UTF-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
<application></application>
<version>1</version>
<threadsafe>true</threadsafe>

Answer 3

我认为您已将此threadsafe属性添加到web.xml而不是appengine-web.xml。确保将其添加到appengine web.xml。感谢。

无法在Google App引擎上部署应用程序：appengine-web.xml不包含<threadsafe>元素</threadsafe>
