Usage

From source file:nl.coinsweb.sdk.FileManager.java

private static void addFileToZip(String fromPath, Path zipPath, ZipOutputStream zos) {

    // Do dark magic, needed to correct ikvm consequences
    String pathInZip = zipPath.toFile().getPath().replace("\\", "/");

    try {//w  w  w.  j  av a2 s.c om
        final byte[] buffer = new byte[1024];
        ZipEntry ze = new ZipEntry(pathInZip);
        zos.putNextEntry(ze);
        log.trace("Adding to zip: " + pathInZip);

        // Write file content
        FileInputStream in = new FileInputStream(fromPath);
