...
1，后台建立obix协议。
2.建立一个bw 可写的节点
3，获取节点值get
http://10.7.10.15/obix/config/Sampler/pw
4：设置节点值：
http://10.7.10.15/obix/config/Sampler/pw/set/<bool val="true" />
下雨了，先回家，等接好图在详细写下，整个过程。
１省了：无法上传图片。
２省了：无法上传图片
３下面是页面内容：
<script type='text/javascript' src='/ord?file:^obixWatch.js'></script>
<script type='text/javascript' src='/ord?file:^jquery.js'></script>
<script type='text/javascript' language='Javascript'>

用页面的话，延迟会有一些，不如那个applet好，但这样我们就可以操作页面显示更好点，如何要查看调用的节点的路径我们就的看http://localhost/obix/
