You can write a Servlet which would read the file contents using the standard input/output stream of java and render the response...
For reference find the code snippet:
String fileName=file.getName();
response.setHeader("Content-Disposition","attachment; filename=\""+fileName+"\"");
response.setContentLength((int)file.length());
response.setContentType("application/zip");
java.io.InputStream in = null;
java.io.OutputStream out = null;
try {
in = new java.io.BufferedInputStream(new FileInputStream(file) );
out = new java.io.BufferedOutputStream(response.getOutputStream() );
pipe(in,out,2048);
} finally {
if( in != null ) try {
in.close();
} catch( IOException ioException ) { ioException.printStackTrace(); }
in.close();
out.flush();
out.close();
public  long pipe(java.io.InputStream in, java.io.OutputStream out,
               int chunkSize) throws IOException {
          if( chunkSize < 1 ) {
               throw new IOException("Invalid chunk size.");
          byte[] buf = new byte[chunkSize];
          long tot = 0;
          int n;
          while( (n=in.read(buf)) != -1 ) {
               out.write(buf,0,n);
               tot += n;
          return tot;
     }
