java如何调用ocx控件

Question

现因项目与嵌入式设备进行访问，ocx控件打包成cab文件，但在html页面上访问时出现找不到相应的属性。html 代码:<object classid="clsid:76771910-597E-4505-96D6-55441A7796DC" id="USBReader1" codeBase="${rc.contextPath}/ocx/ERDriverX.cab#version=1,0,0,1" width="0" height="0">
<param name="Visible" value="0">
<param name="AutoScroll" value="0">
<param name="AutoSize" value="0">
<param name="AxBorderStyle" value="1">
<param name="Caption" value="USBReader">
<param name="Color" value="4278190095">

</object>function WriteCard(CardID,strName){
　  USBReader1.password="fffffffffff";
