                Map<String, String> providerProps = new HashMap<>();
                providerProps.put("Create", "True");

                URI zipURI = new URI("jar:file", zipPath.toUri().getPath(), null);

                FileSystem zipFs = FileSystems.newFileSystem(zipURI,providerProps);

                return zipFs;
            }

            private static void copyToZip(FileSystem zipFs)throws IOException {
                Path sourceFile  = Paths.get("file1.txt");
                Path destFile = zipFs.getPath("\file1Copied.txt");

                Files.copy(sourceFile, destFile, StandardCopyOption.REPLACE_EXISTING);          
            }

are you sure, that Paths.get("mydata.zip") returns a valid path to the file? (File not found?!)

sorry, would have written this as a comment, but currently I'm not allowed to
