前天晚上下载了ajax的视频教程，打算学习下ajax。于是，下载了能够较好支持ajax的IntelliJ <chsdate year="1899" month="12" day="30" islunardate="False" isrocdate="False" w:st="on">8.0.1</chsdate>，开始写一个Hello world式的代码。

这个项目很简单：用户进入一个表单页面（index.html），提交表单（只包含一个用户名参数）给一个Servlet(ClassicServer.java)，然后这个servlet在页面上显示出用户名。

第一次测试：

目录结构和web.xml：

<!--[if gte vml 1]><v:shapetype id="_x0000_t75" coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f"> <v:stroke joinstyle="miter"/> <v:formulas> <v:f eqn="if lineDrawn pixelLineWidth 0"/> <v:f eqn="sum @0 1 0"/> <v:f eqn="sum 0 0 @1"/> <v:f eqn="prod @2 1 2"/> <v:f eqn="prod @3 21600 pixelWidth"/> <v:f eqn="prod @3 21600 pixelHeight"/> <v:f eqn="sum @0 0 1"/> <v:f eqn="prod @6 1 2"/> <v:f eqn="prod @7 21600 pixelWidth"/> <v:f eqn="sum @8 21600 0"/> <v:f eqn="prod @7 21600 pixelHeight"/> <v:f eqn="sum @10 21600 0"/> </v:formulas> <v:path o:extrusionok="f" gradientshapeok="t" o:connecttype="rect"/> <o:lock v:ext="edit" aspectratio="t"/> </v:shapetype><v:shape id="_x0000_i1028" type="#_x0000_t75" style='width:414.75pt; height:164.25pt'> <v:imagedata src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image001.png" o:title="2——1"/> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->

图一：index.html

<!--[if gte vml 1]><v:shape id="_x0000_i1029" type="#_x0000_t75" style='width:219.75pt;height:164.25pt'> <v:imagedata src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image003.png" o:title="2-2"/> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->

图二：ClassicServer页面

<!--[if gte vml 1]><v:shape id="_x0000_i1030" type="#_x0000_t75" style='width:410.25pt;height:258.75pt'> <v:imagedata src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image005.png" o:title="2-3"/> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->

第二次测试：

于是乎，我照搬视频教程里的做法，把servelt直接放进默认包中（没有另外新建包），并修改了web.xml的配置，重启tomcat。访问，呵呵，居然成功了。

目录结构和web.xml如下：

<!--[if gte vml 1]><v:shape id="_x0000_i1027" type="#_x0000_t75" style='width:530.25pt;height:255.75pt'> <v:imagedata src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image007.png" o:title="1"/> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->

图一：index.html

<!--[if gte vml 1]><v:shape id="_x0000_i1026" type="#_x0000_t75" style='width:287.25pt;height:167.25pt'> <v:imagedata src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image009.png" o:title="1_2"/> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->

图二：ClassicServer页面

<!--[if gte vml 1]><v:shape id="_x0000_i1025" type="#_x0000_t75" style='width:312pt;height:130.5pt'> <v:imagedata src="file:///C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\msohtml1\01\clip_image011.png" o:title="1——3"/> </v:shape><![endif]--><!--[if !vml]--><!--[endif]-->

小结：莫非IntelliJ不能完美地支持“包下servlet”？别忘了，你是收费的。

补充：
晚上，我继续使用IntelliJ进行ajax的初级学习，再次遇到上述现象，但是与servlet无关：是我编辑一个javascript文件后，保存之并重新部署该项目（为了避免部署一次不成功的问题，我多次点击了tomcat里面的deplyAll按钮），然后访问页面，查看源代码，发现源代码仍然还是部署之前的旧代码。可见，IntelliJ的部署能力是很差的，竟然屡屡部署不成功。囧！
没办法，重启tomcat，呵呵，这次它自动部署成功了。
