applet自动检测jre局域网下载安装

如果不能访问外网，把codebase的值http://java.sun.com/update/1.6.0/jinstall-6u14-windows-i586.cab#Version=6,0,0,8替换成本地服务器地址就可以了
http://10.70.32.58:8080/iKnow/imageupload/jre-windows-i586.exe，如果客户端没有安装jre，会提示用户安装，安装完后要重新打开浏览器才能使用。
jre-windows-i586.exe下载地址：https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/ViewFilteredProducts-SingleVariationTypeFilter，需要先注册、登录。

源html文件：
<div class="imageuploadform" id="imageuploadcontainer">
  <applet name="imageuploadapplet" style="width:800px;height:650px;" code="com.xxx.imageupload.ImageFrame" codebase="/iKnow/imageupload" archive="/iKnow/imageupload/imageupload.jar"></applet>
</div>


用jdk自带的HtmlConverter转换后的html文件：
#set($userName = "$!{context.getUser()}")
#set($docFullName = "$!{doc.getFullName()}")
#set($docParentName = "$!{doc.getParent()}")
#set($serverIP = "${request.getServerName()}")
#set($appPath = "${request.getContextPath()}")
#set($serverPort = "${request.getServerPort()}")
<div class="imageuploadform" id="imageuploadcontainer">
