运行jetty时出现java.lang.reflect.InvocationTargetException

Question

我尝试使用jetty 9.4.8运行应用程序的部署。这是一款棱角分明的java maven多模块应用

这是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

based on the recommendations of the Application Developer's Guide.

</web-app>

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

<!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">

<Arg>javax.enterprise.inject.spi.BeanManager</Arg>
<Arg>org.jboss.weld.resources.ManagerObjectFactory</Arg>
<Arg/>
</New>
</Arg>
</New>
</Configure>

为了允许Jetty加载服务器Classes，我在web-INF下创建了文件Jetty-web.xml(http://wiki.eclipse.org/Jetty/Reference/Jetty_Classloading)

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<Set name="serverClasses">

</Array>
</Set>
<Call name="prependServerClass">
<Arg>-org.eclipse.jetty.servlet.listener.IntrospectorCleaner</Arg>
</Call>   
<Call name="prependServerClass">

</Call>    
<Call name="prependServerClass">

</Call>
<Call name="prependServerClass">

</Call>
<Call name="prependServerClass">

</Call>
<Call name="prependServerClass">
<Arg>-org.eclipse.jetty.server.handler.ContextHandler</Arg>
</Call>
<Call name="prependServerClass">
<Arg>-org.eclipse.jetty.servlet.ServletContextHandler</Arg>
</Call>
</Configure>

当我运行jetty时，我会收到以下错误消息

感谢您的帮助

Answer 1

针对serverClasses删除<Set>，因为它正在撤消serverClasses正常工作所需的所有现有设置。

删除此分区。。。

<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调用该prependServerClass或addServerClass。

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>
