我最近升级了，即全新安装了 Eclipse Luna 和 Glassfish 4.1。这两个应用程序都是最新的。通过 Eclipse 部署 Java EE 应用程序失败，如果我通过 Glassfish-admin-console 进行标准部署，它可以工作。错误日志是：

GlassFish: Error getting URL for WebResource[module=Module[TachionServer,org.eclipse.jst.jee.server:TachionServer], path=]

堆栈跟踪：

同时我找到了解决方案：在最新的 GlassFish-Tools for Eclipse 最新版本中，似乎有必要创建一个 WEB-INF/glassfish-web.xml，例如：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server   3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app>
    <context-root>/hello2</context-root>
