白痴做Web应用之01：第一个坑，没有创建Artifact

一、创建一个工程

话说连Idea都没用过，只有从Google开始。幸好找到一个页面 http://wiki.jetbrains.net/intellij/Main_Page 。虽说里面列Application servers的没有Jetty，只有GlassFish、JBoss和Tomcat，但是也不能太白痴了，用Creating a simple Web application and deploying it to Tomcat参考一下还是可以的。

按照里面的步骤，创建一个新Project（from scratch）。和里面的步骤稍微不同的是，没有Project不能先添加Server。在Run/Debug Configurations窗口里的Server Tab里添加完Server之后，没有看见右下角有个小小的“Fix”按钮，这就是我的第一坑啊。

二、尝试运行

步骤里面说，“we can start the application straight away: in the Project tool window, right-click index.jsp and choose Run index.jsp on the context menu”，这个右键菜单最后我也没找到，估计是因为Idea版本不同吧。

快捷键F9运行，log输出

没有Error！我很傻的认为这就OK啦，等待着浏览器显示 “ Place your content here ” （这是我index.jsp的默认内容）。可是，浏览器却华丽丽的打开了Jetty的Home页。我试着打开/[ServiceName]，期望着“ Place your content here ” 出现，结果404。第一感觉是根本没有Deploy成功嘛，但是为啥呢？

看了一下Project路径，里面多了一个“out”目录，看来它是Make了的。但是里面out/test/[project name]的out/production/[project name]都是空的。猜想那就是哪里设置不对，导致没有把该打包的文件打包？可是哪里不对啊？

在看步骤里，有一段说“IntelliJ IDEA has produced an artifact to deploy” 这个artifact是啥东西呢，在out里并没有找到啊，没办法继续google。然后找到了这个 体验IntelliJ IDEA + jetty ，才知道我得在Run/Debug Configurations窗口里的Deployment Tab里添加Artifact才行呢。

Artifact添加完毕，再运行，log输出变成了

out里面也生成了artifacts，浏览器打开的也是 “ Place your content here” 啦。

这个Artifact的坑，坑了我一个多小时...
