Zip does not contain files

Question

Hi
I have a query regarding reading zip files created by the following class:
class CreateZip extends Thread {
    CreateZip(Vector FileList) {
        try {
            File zipFile = new File("C:/test.zip");
            if (zipFile.exists()) {
                System.err.println("Zip file already exists, please try another");
                System.exit(0);
            FileOutputStream fos = new FileOutputStream(zipFile);
            ZipOutputStream zos = new ZipOutputStream(fos);
            int bytesRead;
            byte[] buffer = new byte[1024];
            CRC32 crc = new CRC32();
            for (int i=0, n=FileList.size(); i < n; i++) {
                String name = FileList.get(i).toString();
                File file = new File(name);
                //Check to see whether the file already exists or whether
                //it is not a file ie directory...
                if (!file.exists() || !file.isFile()) {
                    System.err.println("Skipping: " + name);
                    continue;
                BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file));
                crc.reset();
                while ((bytesRead = bis.read(buffer)) != -1) {
                    crc.update(buffer, 0, bytesRead);
                bis.close();
                bis = new BufferedInputStream(new FileInputStream(file));
                ZipEntry entry = new ZipEntry(name);
                entry.setMethod(ZipEntry.STORED);
                entry.setCompressedSize(file.length());
                entry.setSize(file.length());
                entry.setCrc(crc.getValue());
                zos.putNextEntry(entry);
                while ((bytesRead = bis.read(buffer)) != -1) {
                    zos.write(buffer, 0, bytesRead);
                bis.close();
            zos.close();
        } catch (Exception e) {
            e.printStackTrace();
}It accepts a vector which contains files and/or folders and this is supposed to add them to a zip file.
All that happens is the zip file is created but when I open it there are no files inside that are visible. The file size does appear to grow and there are no errors generated.
Any ideas?
Many thanks

You wnet to the CVI link instead of the LabVIEW one. The LabVIEW driver can be found here.
