File upload using JSP throwing error java.io.FileNotFoundException:

[vishalonne]

I am trying to upload file from postantivirus1.jsp after selecting the file from postantivirus.jsp Here is the code
Postantivirus.jsp

Anti Virus Software : </td><td><input type=file name="fname"><br/>
<input type=submit value="submit"></td><td><input type=submit value="clear">

Postantivirus1.jsp

String s=request.getParameter("fname");
    System.out.println(s+" s");
FileInputStream fis=new FileInputStream(s);
    System.out.println(fis+" fis");
String s1=application.getRealPath("/");
String destFolder = s1 + "images/";
s1= destFolder +avno+".zip"; 
FileOutputStream fos=new FileOutputStream(s1);
int x=0;
while((x=fis.read())!=-1)
{
    System.out.println(x);
fos.write(x);
}
fis.close();
fos.close();

But I am getting following error on jsp page because system is not able to find the file due to insufficient path information,

java.io.FileNotFoundException: Branch2.java (The system cannot find the file specified)

how can mention the path which can be any where in computer, so the system can get the specified file for reading and then writing. Any suggestion most welcome.
