viewimage.jsp
<%@ page contentType="image/jpeg; charset=gb2312" language="java" errorPage="" %>
<%@ page import="java.sql.*" %>
<%@ page import="java.util.*"%>
<%@ page import="java.text.*"%>
<%@ page import="java.io.*"%>
<jsp:useBean id="get_argu_info" class="com.infoks.lzp.bean.get_pro_picture">

<jsp:setProperty name="get_argu_info" property="tablename" value="wky_image"/>
</jsp:useBean>
<%
session.invalidate();
request.getSession(true);
ResultSet rs=get_argu_info.getRs();
System.out.println("get resultset");
response.setContentType("image/jpeg");
System.out.println("set response");
// try {
rs.next();
ServletOutputStream sout = response.getOutputStream();

InputStream in = rs.getBinaryStream("pic");
byte b[] = new byte[256];
int length = 256;
while((length=in.read(b)) != -1)
{
sout.write(b,0,length);
sout.flush();
}

sout.close();

// }
// catch(Exception e){System.out.println(e);}
%>

程序虽然有了预期的效果，但是没调用一次viewimage，他都会报一个错：“getOutputStream() has been called for this response”,
各位高手，能不能解决这个问题啊。拜托，拜托。。。。。。。
问题解决，就给分！！！
