Subject query about PEAR installation for DUCC
Date Tue, 14 Oct 2014 22:40:44 GMT
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.
