【问题描述】：

尝试在 JBoss 6.1.0 中部署 WAR 时显示以下错误

DEPLOYMENTS IN ERROR:
  Deployment
"vfs:///D:/workspace/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_AS_6.x1555321418499/deploy/MyProject.war" is in error due to the following reason(s): 

 org.jboss.xb.binding.JBossXBRuntimeException: filter cannot appear in this position. Expected content of web-app is unordered_sequence: error-page* welcome-file-list? servlet-mapping* login-config? mime-mapping* distributable? session-config? security-role* taglib* security-constraint* context-param* servlet* all descriptionGroup? unordered_sequence jndiEnvironmentRefsGroup?

以下是web.xml文件

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:web="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>false</param-value>
  </context-param>

 <filter>
    <filter-name>AuthenticationFilter</filter-name>
    <filter-class>mypackage.restauthentication.RestAuthenticationFilter</filter-class>
 </filter>
 <filter-mapping>
    <filter-name>AuthenticationFilter</filter-name>
    <url-pattern>/services/*</url-pattern>
 </filter-mapping>

 <servlet>
    <servlet-name>REST Service</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

     <init-param>
      <param-name>jersey.config.server.provider.packages</param-name>
      <param-value>mypackage.restauthentication</param-value>
     </init-param>

   <load-on-startup>1</load-on-startup>
 </servlet>
 <servlet-mapping>
   <servlet-name>REST Service</servlet-name>
   <url-pattern>/service/*</url-pattern>
 </servlet-mapping>
</web-app>

根据错误信息，<filter> 被错误地放置在web.xml 中。 web-app 的预期内容是 unordered_sequence: error-page* welcome-file-list? servlet 映射* 登录配置？ mime-mapping* 可分发？会话配置？ security-role* taglib* security-constraint* context-param* servlet* all descriptionGroup？ unordered_sequence jndiEnvironmentRefsGroup？

放置相同物品的正确顺序是什么？这是一个使用基本身份验证部署 Jersey REST Web 服务的 Web 存档。

【参考方案1】：

试试这个..
