jsp页面不正常显示,显示的是源代码,不是想要的效果.

JSP里边是这样写的:
<%@ page contentType="text/html; charset=GBK" %>
<%@ page import = "com.ai.oms.pf.svg.InstanceSvgConst" %>
<jsp:useBean id="InstanceSvg" class="com.ai.oms.pf.svg.InstanceSvg" scope="session" />
<%
     String strOrderId = request.getParameter("OrderId");
     String strBusinessTypeCode = request.getParameter("OrderType");     InstanceSvg.getImageSvgs(request,response);
     String strSVGXmlString = (String)request.getAttribute(InstanceSvgConst.InstanceImageSvgs);     if (strSVGXmlString==null){
       out.print("未找到相应图示信息或查询出现异常！");
       return;
     }
     session.setAttribute(InstanceSvgConst.InstanceImageSvgs,null);
     session.setAttribute(InstanceSvgConst.InstanceImageSvgs,strSVGXmlString);
%>
<html><head>
<title>Image</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
</head>
<script language="javascript">
   function ShowTaskInfo(instanceid,taskid)
   {
        window.open('<%=InstanceSvgConst.UrlInstanceTaskInfo%>?<%=InstanceSvgConst.SvgInstanceId%>='+instanceid+'&amp;<%=InstanceSvgConst.SvgTaskId%>='+taskid,'','height=200,width=200,top,toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,status=no')
   }
</script>
<body bgcolor="#ffffff" onload="init();">
<%
     out.print("<object type=\"image/svg+xml\" name=\"fig3\" width=\"1000\" height=\"800\">");
     out.print("<param name=\"src\" value=\"detailImage.jsp\"/>");
     out.print("</object>");
%>
</body>
</html>发步到weblogic 705上后,页面上显示的是:
- <html>
- <head>
  <title>Image</title> 
  <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> 
  </head>
  <script language="javascript">function ShowTaskInfo(instanceid,taskid) { window.open('/oms/pf/query/instanceTaskInfo.jsp?InstanceId='+instanceid+'&TaskId='+taskid,'','height=200,width=200,top,toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,status=no') }</script> 
- <body bgcolor="#ffffff" onload="init();">
- <object type="image/svg+xml" name="fig3" width="1000" height="800">
  <param name="src" value="detailImage.jsp" /> 
  </object>
  </body>
  </html>
