String filePath = request.getParameter("filePath");
filePath = request.getServletContext().getRealPath("/") + filePath;
String targetPath = request.getParameter("target");
File file = new File(filePath);
FileInputStream in = new FileInputStream(file);


FileOutputStream out = new FileOutputStream(targetPath + "/"
+ file.getName());


int c;
byte buffer[] = new byte[1024];
while ((c = in.read(buffer)) != -1) {
for (int i = 0; i < c; i++)
out.write(buffer[i]);
}


in.close();
out.close();
