Verificar a existencia de um ficheiro

Recommended Posts

Las Vegas

Boas comunidade,

Necessitava de uma ajuda, se possível, que não estou a conseguir.

Quando faço um upload para a minha pasta de que se encontra no ftp server, antes de o fazer gostava de verificar se o nome  de um documento já existe. Para evitar o overwrite.

Desde já obrigado a todos

Já consegui... deixo aqui a solução para quem tiver a mesma duvida

FTPClient ftp = new FTPClient();
                    int port = 21;                  
                   ftp.connect("ftp server", port);
                   ftp.login("user","pass");                                      
                   ftp.enterLocalPassiveMode();          
                   ftp.setFileType(FTP.BINARY_FILE_TYPE);
                   
                   File fileName = save.getSelectedFile();
                   String localFile = "/" + fileName.getName();
                                                         
                   FileInputStream input = new FileInputStream(fileName);
                   System.out.println("total " + input.available());
                   
                   FTPFile files = ftp.mlistFile(localFile);
                   
                      if(files != null){
                         JOptionPane.showMessageDialog(null, "Já existe um documento com o mesmo nome."); 
                       }else{          
                           boolean out = ftp.storeFile(localFile, input);
                                input.close();
                            if(out){
                              System.out.println("Sucess");
                            }
                       }
