dom4j-1.6.1.jar itextpdf-5.4.0.jar itext-rups-5.4.0.jar and running it: java -jar itext-rups-5.4.0.jar $java -version java version "1.7.0_17" Java(TM) SE Runtime Environment (build 1.7.0_17-b02) Java HotSpot(TM) Server VM (build 23.7-b01, mixed mode) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/802021 Title: itext-rups.jar not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libitext-java/+bug/802021/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
