运行码头时出现java.lang.reflect.InvocationTargetException

我尝试使用Jetty 9.4.8运行应用程序的部署。这是一个有角度的Java Maven多模块应用程序

这是我的web.xml 

PAYMENT_UPDATED

我通过在WEB-INF（http://www.agorava.org/news/2012/07/10/Starting-a-CDI-webapp-from-Maven-with-Weld-servlet-and-jetty-plugin/）下创建jetty-env.xml，通过JNDI公开了CDI bean管理器。

要允许Jetty加载服务器类，我在WEB-INF（http://wiki.eclipse.org/Jetty/Reference/Jetty_Classloading）下创建文件jetty-web.xml 

<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure id="webAppCtx" class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="BeanManager" class="org.eclipse.jetty.plus.jndi.Resource">
        <Arg>
            <Ref id="webAppCtx"/>
        </Arg>
        <Arg>BeanManager</Arg>
        <Arg>
            <New class="javax.naming.Reference">
                <Arg>javax.enterprise.inject.spi.BeanManager</Arg>
                <Arg>org.jboss.weld.resources.ManagerObjectFactory</Arg>
                <Arg/>
            </New>
        </Arg>
    </New>
</Configure>

当我运行码头时，出现以下错误消息

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

谢谢您的帮助

将<Set>与serverClasses相对应，将其撤消，因为这将撤消serverClasses正常运行的所有现有（和必需）设置。

删除此部分... 

<Set name="serverClasses">
    <Array type="java.lang.String">
        <Item>-org.eclipse.jetty.servlet.ServletContextHandler.Decorator</Item>
    </Array>
</Set>

您应该将对serverClasses的修改限制为对现有列表进行prependServerClass或addServerClass的调用。

示例：

<Call name="prependServerClass">
  <Arg>-org.eclipse.jetty.servlet.ServletContextHandler</Arg>
</Call>
<!-- or -->
<Call name="addServerClass">
  <Arg>-org.eclipse.jetty.servlet.ServletContextHandler</Arg>
</Call>

它解决了我的问题。但是，我还有另一个错误

在一开始，我认为这是由于多个档案中引用了一个类。但是错误消息指出“正在调用的类...”
