Embebed jetty + h2 + jdic + substance => “桌面应用”也可以这么开发

gqinvs

　　1. 搞一个差不多的界面，要不要登陆之类的就看自己情况了；
　　https://substance.dev.java.net/learn.html
　　2. 适当地方放一个jdic webbrowser的jpanel，在windows下虽然只能嵌入IE，但做一个本地软件速度应该不慢了；
　　3. 嵌入一个Jetty Server和H2 Server
　　我还是把datasource放到jndi了，当然也可以不这么搞。（我用的是jetty6.1x）
　　这个，我干脆献丑上个代码妥了——

　　web.xml里最好加一个h2的consoleservlet
　　<servlet>

<servlet-name>H2Console</servlet-name>
<servlet-class>org.h2.server.web.WebServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>H2Console</servlet-name>
<url-pattern>/console/*</url-pattern>
</servlet-mapping>
　　4. 当然为了好搞热部署或开发，弄一个lightweight的脚本开发支架就更好点；
　　5. 最后用jsmooth或launch4j打个包，这么搞下子一般“领导”就能糊弄过去了；嘿嘿
　　BTW——本来有个需求，做桌面应用的，本打算用swing（其他的不会么，而且swing也菜的很），可是用户对LAF要求太高了，拿css的一些思想做设计，比如，一些button的hover效果，一个**渐变背景图片，控件的位置要很灵活——反正一些需求不是像修改个html几行代码就能搞定了，我对swing的LAF定制也没啥研究，所以就有了以上这个变通。用起来还不错！
