Hi,
I did the same way you told me. Still not returning any output
irb
irb(main):001:0> logfile = '/home/suppalapati/java.txt'
=> "/home/suppalapati/java.txt"
irb(main):002:0> line_num=0
=> 0
irb(main):004:0> require 'facter/util/file_read'
=> true
irb(main):005:0> log = Facter::Util::FileRead.read(logfile)
=> "\n/usr/java/jdk1.7.0_25/jre/bin/java

irb(main):006:0> unless log.nil?
irb(main):007:1> log.each_line do |line|
irb(main):008:2* if line.include?('java')
irb(main):009:3> line_num += 1
irb(main):010:3> javaid, val = %x[#{log}]
irb(main):011:3> Facter.add("java_#{javaid}") do
irb(main):012:4* puts val
irb(main):013:4> end
irb(main):014:3> puts val1
irb(main):015:3> end
