When I create an embedded derby JPA app by wrapping the jpa classes in a netbeans module an include it into my platform app It will work fine when running it in the IDE (database will create itself and i can persist data), however, when i package the installer shell for linux and install, my app will no longer operate properly. Statements after the getEntityManager call do not execute and there are no error messages to observer. I then tried compiling my project in windows 7 and was able to run it properly both inside the IDE and outside the IDE from the nb platform installer. Basically i think this must have something to do with the installer packaging for the 7.2 platform on ubuntu 12.04 I've documented some of the detail here and will be happy to supply more info if it will help. http://stackoverflow.com/questions/12220881/netbeans-platform-app-on-ubuntu-12-with-embedded-derby-db-and-jpa Regards, James
OK. Why the statements don't execute? Try to use debugger.
Hi, I'm not sure how to debug because the anomaly only behaves when I create the installer for Ubuntu. It works fine when running in the IDE in both normal and debug modes. Would you know if there is a error log for a NetBeans platform app that I can look into? Here are the lines: File homeDir = new File(System.getProperty("user.home")+"/.simdriver"); homeDir.mkdirs(); Msg.info("home dir is: "+homeDir.getAbsolutePath()); System.setProperty("derby.system.home", homeDir.getAbsolutePath()); System.setProperty("derby.stream.error.file", homeDir.getAbsolutePath()+"/log/derby.log"); Msg.info("Check B1"); System.out.println("Check B1"); // this line does not appear to work: em = Persistence.createEntityManagerFactory("VmCfgLibPU").createEntityManager(); // These lines do not execute when running the installed version. They do execute when running in the IDE with or wo the debugger. System.out.println(" the em is: "+em); System.out.println("em is open: "+em.isOpen()); System.out.println("Check C1");
