You can't write scriptlet inside onclick, you should create a new servlet to download the file and give it's link inside you anchor tag.

public class ServletDownloadDemo extends HttpServlet{

  private static final int BYTES_DOWNLOAD = 1024;

  public void doGet(HttpServletRequest request, 
   HttpServletResponse response) throws IOException{
    response.setContentType("application/pdf");
    response.setHeader("Content-Disposition",
                     "attachment;filename=downloadname.pdf");
    ServletContext ctx = getServletContext();
    InputStream is = ctx.getResourceAsStream("Pdf file to download");

    int read=0;
    byte[] bytes = new byte[BYTES_DOWNLOAD];
    OutputStream os = response.getOutputStream();

    while((read = is.read(bytes))!= -1){
        os.write(bytes, 0, read);
    }
    os.flush();
    os.close(); 
   }
}

please set to according My Jsp code coz am Not Using servlet please — Aman Kumar, Jul 24 '13 at 08:51
@AmanKumar: You can simply write a new jsp with download file code inside scriplet and give path of this jsp inside your anchor tag. — Ankur Lathi, Jul 24 '13 at 09:02

The onClick attribute is plain Javascript, executed on the browser when the user click on it. You want to have a second JSP or plain servlet, that simply writes to the HTTPServletResponse.getOutputStream(). Then put its location in the href attribute of the a element.
