Question #166990 on Sikuli changed: https://answers.launchpad.net/sikuli/+question/166990
Description changed to: Hi there, I have built a Sikuli Script that runs successfully from command line in linux: OS Debian 6.0.2 GNOME Desktop Version 2.30.2 This is how I would run the script directly (using full paths) in my user session: /usr/share/my-path/Sikuli-IDE/sikuli-ide.sh my-path/mydemo.sikuli.skl Next I want to be able to run this script daily at a specified time using crontab (my username). This https://help.ubuntu.com/community/CronHowto says that it is possible to run gui applications via cronjobs. This can be done by telling cron which display to use. So I have followed the suggestion when specifying the job in the crontab (my username) 15 15 * * * env DISPLAY=:0 /usr/share/my-path/Sikuli-IDE/sikuli-ide.sh my-path/mydemo.sikuli.skl However, this error occurs when the cronjob runs (the error is emailed from the cron-daemon): -------------------------------------- No protocol specified Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable. at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method) at sun.awt.X11GraphicsEnvironment.access$100(X11GraphicsEnvironment.java:62) at sun.awt.X11GraphicsEnvironment$1.run(X11GraphicsEnvironment.java:166) at java.security.AccessController.doPrivileged(Native Method) at sun.awt.X11GraphicsEnvironment.<clinit>(X11GraphicsEnvironment.java:142) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:186) at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:82) at sun.awt.X11.XToolkit.<clinit>(XToolkit.java:112) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:186) at java.awt.Toolkit$2.run(Toolkit.java:849) at java.security.AccessController.doPrivileged(Native Method) at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:841) at javax.swing.ImageIcon.<init>(ImageIcon.java:136) at javax.swing.ImageIcon.<init>(ImageIcon.java:155) at org.sikuli.ide.SikuliIDE.getIconResource(SikuliIDE.java:106) at org.sikuli.ide.SikuliIDE.<clinit>(SikuliIDE.java:85) Could not find the main class: org.sikuli.ide.SikuliIDE. Program will exit. ----------------------------------------- Do you have any other suggestions? Surely other folks must successfully execute their Sikuli Scripts via linux cronjobs. Thanks. Carla ADDENDUM: This is how I solved the issue. More reading tells me this: Gnome Schedule (crontab) does not support setting environment variables for recurrent tasks ... In the meantime, manually create a script that first defines DISPLAY variable and then calls the graphical application. This shell script runs the Sikuli Script successfully from the crontab. The secret ingredient was "xhost local:" -- #!bin/bash DISPLAY=:0; export DISPLAY xhost +local: /usr/share/my-path/Sikuli-IDE/sikuli-ide.sh my-path/mydemo.sikuli.sk #end script --- cg -- You received this question notification because you are a member of Sikuli Drivers, which is an answer contact for Sikuli. _______________________________________________ Mailing list: https://launchpad.net/~sikuli-driver Post to : sikuli-driver@lists.launchpad.net Unsubscribe : https://launchpad.net/~sikuli-driver More help : https://help.launchpad.net/ListHelp
