Hi, I had a query about pear installation on a "headless" system via the command line. I dont see any instructions in the documentation on how to proceed.
Specifically, I'm attempting to run the Raw Text Processing example documented in the DUCC Book, (http://uima.apache.org/d/uima-ducc-1.0.0/duccbook.html#x1-1380009) The problematic step is "Installing the OpenNLP Pear". Almost everywhere I have seen, it instructs the use of the GUI Installer. DUCC Book points to the runPearInstaller script (which is strangely not shipped with the DUCC binaries) I managed to find it in the shipped binaries of UIMA. I set unpacked the binaries and set up the environment as instructed in the UIMA SDK documentation (the script resides in $UIMA_HOME/bin) and running it fails with the following error. runPearInstaller.sh --help Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it. at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207) at java.awt.Window.<init>(Window.java:535) at java.awt.Frame.<init>(Frame.java:420) at java.awt.Frame.<init>(Frame.java:385) at javax.swing.JFrame.<init>(JFrame.java:174) at org.apache.uima.tools.pear.install.InstallPear.<init>(InstallPear.java:824) at org.apache.uima.tools.pear.install.InstallPear.createAndShowGUI(InstallPear.java:789) at org.apache.uima.tools.pear.install.InstallPear.access$1500(InstallPear.java:80) at org.apache.uima.tools.pear.install.InstallPear$12.run(InstallPear.java:815) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:312) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:733) at java.awt.EventQueue.access$200(EventQueue.java:103) at java.awt.EventQueue$3.run(EventQueue.java:694) at java.awt.EventQueue$3.run(EventQueue.java:692) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:703) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:161) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) at java.awt.EventDispatchThread.run(EventDispatchThread.java:91) I would appreciate if someone can give me some pointers on how to proceed, Thanks, Best, -- Amit Gupta
