Thank you for your answer, This is my solution if another people need it :
This is the content of my RPC method in server side. String realPath = getServletContext().getRealPath("/").concat(gwtModuleName); // Or other folder you want to access File f = new File(realPath); for (String s : f.list()) { if (s.matches(PATTERN)) { // Do the job } } Hope this will help. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
