path - Setting up environment variable in linux -

while installing uima got steps in readme file

* set java_home directory of jre installation use uima.   * set uima_home apache-uima directory of unpacked apache uima distribution * append uima_home/bin path  * please run script uima_home/bin/adjustexamplepaths.bat (or .sh), update    paths in examples based on actual uima_home directory path.    script runs java program;    must either have java in path or set environment variable java_home    suitable jre. 

i opened /etc/environment , perfomed changes:

path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/uima_home/bin" java_home="/usr/lib/jvm/java-7-openjdk-i386" uima_home="/root/desktop/karim/software/uima/uima_sdk_1.4.5" 

after executed:

uima/uima_sdk_1.4.5/bin# ./documentanalyzer.sh 

which gave error:

./documentanalyzer.sh: 2: .: can't open /bin/setuimaclasspath.sh 

documentanalyzer.sh code :

#!/bin/sh . "$uima_home/bin/setuimaclasspath.sh" if [ "$java_home" = "" ];   java_home=$uima_home/java/jre fi "$java_home/bin/java" -cp "$uima_classpath" -xms128m -xmx900m "-duima.home=$uima_home" "-duima.datapath=$uima_datapath" -dvns_host=$vns_host -dvns_port=$vns_port "-djava.util.logging.config.file=$uima_home/logger.properties" com.ibm.uima.reference_impl.application.docanalyzer.documentanalyzer 

what mistake here? guess set environment variable correctly

i think answers given adding $ variable uima_home in path variable correct, but, think lacking export command variables. look, after set values, should writhe in /etc/environment:

export uima_home export java_home export path 

that way, able use them later (always remember fix path variable $uima_home well).

if not work, try rebooting computer after setting variables said.

in case not work either, try repeating process , in console (after doing everythin on again) try using following command:

source /etc/environment 

fianlly, if not work, try setting variables in file called /etc/profile (do same process: setting varialbes , exporting them), , should work.
