I have a really simple program where I’m trying to add a directory to a new zip file. The code:

public class Encrypt {
    public static void main(String[] args) {
        TFile srcFile = new TFile(args[0]);
        TFile destFile = new TFile("/home/myuser/archive.zip");
        try {
            TFile.umount();
        } catch (FsSyncException e1) {
            e1.printStackTrace();
        }

        try {
            if (destFile.isArchive() || destFile.isDirectory())
                 destFile = new TFile(destFile, srcFile.getName());
            srcFile.cp_rp(destFile);
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            TFile.umount();
        } catch (FsSyncException e) {
            e.printStackTrace();
        }
    }
}

This is pretty much the code from here.
The exception:

I’m not able to find anything related to this exception on the project page or other pages. Has anyone seen this before? I’m using TrueZip 7.1.4.

    Right, there are run time dependencies on the file system driver modules you want to access.

    E.g. if you want to access ZIP files, you need to have the JARs of the modules TrueZIP Driver ZIP (truezip-driver-zip) and TrueZIP Driver File (truezip-driver-file) on the run time class path.
