Question

我正在使用Eclipse开发应用程序引擎应用程序，当我想部署应用程序时，我得到了这个错误：

'Deploying APP_NAME to Google' has encountered a problem
 An internal error occured during "Deploying APP_NAME to Google"

详情如下：

An internal error occurred during: "Deploying APP_NAME to Google".
Received IOException parsing the input stream for /home/michael/workspace/APP_NAME/war/WEB-INF/web.xml

知道如何解决这个问题吗？

感谢您的帮助。

奇怪的是，每次部署应用程序时都没有错误。

web.xml：

实际上，当我收到错误时，会出现web.xml文件中的错误：

Multiple annotations found at this line :
- Attribute "version" must be declared for element type "web-app".
- Attribute "xmlns" must be declared for element type "web-app".

但是现在，经过更正后，我文件的开头看起来如下：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">

    <!-- Servlets -->

    <servlet>
        <servlet-name>deleteAllUniversityServlet</servlet-name>
        <servlet-class>com.APP_NAME.api.DeleteAllUniversities</servlet-class>
    </servlet>

        ...

我不明白什么是错的......

问题似乎来自DOCTYPE，因为当我将DOCTYPE作为注释时，应用程序正确部署。

您没有关闭<web-app>节点试试这个：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
 <servlet>
  <servlet-name>deleteAllUniversityServlet</servlet-name>
  <servlet-class>com.APP_NAME.api.DeleteAllUniversities</servlet-class>
 </servlet>

 <servlet>
  <servlet-name>deleteAllCountryServlet</servlet-name>
  <servlet-class>com.APP_NAME.api.DeleteAllCountries</servlet-class>
 </servlet>

 <servlet>
  <servlet-name>deleteAllCitiesServlet</servlet-name>

 <servlet>

 <servlet>
