Question

我有一个使用Restlet EE 2.2的应用程序，它在Tomcat 7中运行良好但在JBOSS 6.2中失败（参见下面的堆栈跟踪）。我从跟踪中发现它没有找到HTTP堆栈类，但我对JBOSS很少熟悉。

今天有一个类似的question被问到，虽然不是关于JBOSS。提前谢谢！

Answer 1

根据this jira页面，您需要更新module.xml文件。

添加以下

<path name="com/sun/net/httpserver"/>

发现于：

中的module.xml文件

modules\system\layers\base\sun\jdk\main

Answer 2

使用JBoss7.1.1最后将<path name="com/sun/net/httpserver"/>添加到modules \ sun \ jdk \ main解决了这个问题。

JBOSS中的Restlet：Java嵌入式运行时环境中的com.sun.net.httpserver.HttpHandler ClassNotFound异常
