Hello, if you make use of the servlet then you can solve your problem by simply making use of the code below:

DataOutput Out = new DataOutputStream (res.getOutputStream ());
res.setContentType ( "image / jpeg");
String img = request.getParameter ( "imageName");
File filename = null;
FileInputStream in = null;
String filenamePath = img.replace ("/", "\ \");
filename = new File (filenamePath);
if (File.Exists ())
return;
in = new FileInputStream (filename);
res.setContentLength ((int) filename.length ());
byte value [] = new byte [4096];
int number;

while ((number = in.read (value))! = -1)
{
Out.Write (value, 0, number);
}

in.close ();

Hello, I think you must need to make use of the code below for getting your refresh of page after uploading an image in jsp:

<% @ Page import = "java.sql .*;"%>
<%
Connection con = null;
RequestDispatcher requestD;

try
{
pass String = (String) session.getAttribute ( "pass");
String lgin = "*****";
String reqpass = "******";
String url = "jdbc: mysql ://*******/ schneider_final";
Class.forName ( "com.mysql.jdbc.Driver"). NewInstance ();
con = DriverManager.getConnection (url, lgin, reqpass);
java.sql.Statement statement = con.createStatement ();
java.sql.ResultSet rs = statement.executeQuery ( "select * from users where pass =" + pass);

if (rs.first ())
{
String logo = rs.getString ( "logo");

if (logo! = null)
{
out.println ( "<img src=\""+request.getContextPath()+"/SrvShowLogo?imageName="+logo+"\">");
out.println ( "</ div>");
}
}
rs.close ();
statement.close ();
}
catch (Exception e)
{ }
%>
