jsp如何获得客户端的IP地址？

java类：public static String getIpAddr(HttpServletRequest request) { 
        String ip = request.getHeader("X-Forwarded-For"); 
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
            ip = request.getHeader("Proxy-Client-IP"); 
        } 
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
            ip = request.getHeader("WL-Proxy-Client-IP"); 
        } 
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
            ip = request.getHeader("HTTP_CLIENT_IP"); 
        } 
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
            ip = request.getHeader("HTTP_X_FORWARDED_FOR"); 
        } 
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
            ip = request.getRemoteAddr(); 
        } 
        return ip; 
    }  

调用ServletRequest 接口方法
request.getremoteaddr()：获得客户端的ip地址

<%!public String getRemortIP(HttpServletRequest request) {
if (request.getHeader("x-forwarded-for") == null) {
return request.getRemoteAddr();
}
return request.getHeader("x-forwarded-for");
}%>

这段先贴JSP里
然后再表单里
你照这个类似做吧
<form name="adminloginForm" method="post" action="test.do">
   <td align="center"><%=getRemortIP(request)%>"</td>
   <input type="submit" name="Submit" value="确定">
</form>
