Hello Ian. JFlex was probably never intended to be used directly in Fedora. The problem above is caused by missing java_cup in the CLASSPATH. I'll check that and we could add modified version of the shellscript in the package for direct usage. You can try the following till it's fixed: export CLASSPATH=/usr/share/java/jflex.jar:/usr/share/java/java_cup.jar java JFlex.Main Regards, Jaromir. jflex-1.4.3-7.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/jflex-1.4.3-7.fc17 jflex-1.4.3-7.fc16 has been submitted as an update for Fedora 16. https://admin.fedoraproject.org/updates/jflex-1.4.3-7.fc16 Package jflex-1.4.3-7.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days.

I may be missing something really obvious here, but the Fedora jflex package neither installs the script that comes with the upstream package nor supplies its own, so how is a naïve user going to run it? $ rpm -q jflex jflex-1.4.3-5.fc15.noarch $ jflex -bash: jflex: command not found $ java JFlex.Main Exception in thread "main" java.lang.NoClassDefFoundError: JFlex/Main Caused by: java.lang.ClassNotFoundException: JFlex.Main at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: JFlex.Main.
