以下代码显示不出图片，请问是为什么，我的数据库是MySQL数据库

<%@ page import="java.io.*"%>
<%@ include file="Connection/Connection.jsp"%>
<%Statement statement=con.createStatement();
String query = "Select aa01a58 from AA01 where p_number='020618150208226001'";
ResultSet rs=statement.executeQuery(query);
if (rs.next())
{
response.setContentType("image/jpeg");
InputStream in=rs.getBinaryStream(1);
OutputStream out1=response.getOutputStream();
byte buffer[]=new byte[4096];
for( ; ;)
{
int nBytes=in.read(buffer);
if(nBytes==-1)
break;
out1.write(buffer,0,nBytes);
}

in.close();
out1.flush();
out1.close();
}
rs.close();
statement.close();
con.close();
%>
