Hello, in previous versions of CipherMail it was possible to import certificates with the following command: cd /usr/share/djigzo java -cp djigzo.jar mitm.application.djigzo.tools.CertStore --import-keys --dir /path/to/certs/ --keystore-password SeCrEt This fails in the current version 4.10.0 (virtual appliance): Error: Could not find or load main class mitm.application.djigzo.tools.CertStore Is this import no longer available? /usr/share/djigzo-gateway-console/lib/djigzo.jar still contains CertStore.class When I add the path to the jar file, I only get another error: java -cp /usr/share/djigzo-gateway-console/lib/djigzo.jar mitm.application.djigzo.tools.CertStore --import-keys --dir /path/to/certs/ --keystore-password SeCrEt Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/MissingArgumentException         at java.lang.Class.getDeclaredMethods0(Native Method)         at java.lang.Class.privateGetDeclaredMethods(Class.java:2701)         at java.lang.Class.privateGetMethodRecursive(Class.java:3048)         at java.lang.Class.getMethod0(Class.java:3018)         at java.lang.Class.getMethod(Class.java:1784)         at sun.launcher.LauncherHelper.validateMainClass(LauncherHelper.java:650)         at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:632) Caused by: java.lang.ClassNotFoundException: org.apache.commons.cli.MissingArgumentException         at java.net.URLClassLoader.findClass(URLClassLoader.java:382)         at java.lang.ClassLoader.loadClass(ClassLoader.java:418)         at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352)         at java.lang.ClassLoader.loadClass(ClassLoader.java:351)         ... 7 more Thanks your any hints or suggstions.
