Servlets are executed on server, not on the client machine, so they
cannot write to disks on the client machine. But you can pop-up
browser's "Save as ..." dialog with this code:
import java.io.*;
import java.util.*;
import java.text.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SaveAs extends HttpServlet
{
public void doGet (HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
PrintWriter out;
if(request.getHeader("user-agent").indexOf("MSIE")!= -1)
{
response.setContentType("application/x-my-type");
response.setHeader("Content-Disposition","inline;filename=my_file_name");
}
else
{
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","inline;filename=my_file_name.txt");
}
out = response.getWriter();
try {
/
out.println("This text will be saved in a text file.");
//-----
} catch (Exception ex) {out.println(ex.getMessage());ex.printStackTrace(out);}
}
}
