没有任何根本原因的 IllegalStateException

Question

当我尝试在服务器中部署我的项目 war 文件时，出现以下异常。

请帮我解决这个问题，我也没有得到任何根本原因，以便我可以检查。

如果您需要任何文件详细信息，请询问 我的 web.xml

<web-app >
<display-name>Archetype Created Web Application</display-name>
<servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.gaian.adservice</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<resource-ref>
    <description>DB Connection</description>
    <res-ref-name>project</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

关于我之前遇到的错误

Caused by: org.apache.catalina.LifecycleException: Failed to process either the global, per-host or context-specific context.xml file therefore the [/BannerAdServing] Context cannot be started.
at org.apache.catalina.startup.FailedContext.startInternal(FailedContext.java:199)
at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:152)
... 48 more

谢谢！

Answer 1

我已经在我的应用程序中编写了 context.xml

<context>
  ...
</context>

但我发现它应该以大写开头

 <Context>
  ...
</Context>

感谢大家的时间和帮助
