在jsp中调用自己写的ocx为什么每次都提示安装？
每次运行调用ocx的jsp页时都会提示安装，为什么？
JSP页代码如下
<%@ page contentType= "text/html;charset=GB2312 " language= "java " %>
<%@ page import = "java.io.IOException,javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpSession,javax.servlet.jsp.*; "%>
<html>
<head>
<title> OCX测试 </title>
</head>
<body Leftmargin=0 topmargin=0 rightmargin= "0 " bottommargin= "0 ">
<table width= "100% " height= "100% ">
<tr height= "100% "> <td valign= "top ">
<%
//System.gc();
StringBuffer outString = new StringBuffer( " ");
outString.append( " <OBJECT id = \ "test\ " \n ");
outString.append( "classid=\ "clsid:BB3A37B1-A516-4BBA-9F97-91DED12CAF30\ " \n ");
outString.append( "codebase=\ "./test.cab#version=1,0\ " \n ");
outString.append( "width=100% height=100% align=center hspace=0 vspace=0> \n ");
outString.append( " </OBJECT> \n ");
JspWriter writer = pageContext.getOut();
try
{
writer.print(outString.toString());
}
catch(IOException e)
{
throw new JspException(e.getMessage());
}
%>
</td>
</tr>
</table>
</body>
</html>
------解决方案--------------------
为什么不作为静态html元素 <object> </object> 直接写，而用java？
