Using JRuby, put data into HBase and pull it back out, using HBase 0.20

environment.sh

export JRUBY_CLASSPATH="/usr/share/maven-repo/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.jar:/usr/share/maven-repo/log4j/log4j/1.2.15/log4j-1.2.15.jar"
export HADOOP_CLASSPATH="/src/taproot/server/lib/InvPocTransform.jar:/usr/lib/hadoop-0.20/hadoop-core.jar:/usr/lib/hbase/hbase.jar:/usr/lib/hbase/lib/zookeeper.jar:/usr/lib/hbase/lib/guava-r05.jar:$HADOOP_CLASSPATH"

jruby-hbase-round-trip.rb

#!/usr/bin/ruby
include Java
require 'java'

ENV["HADOOP_CLASSPATH"].split(":").each {|jar| require jar}
ENV["JRUBY_CLASSPATH"].split(":").each {|jar| require jar}

include_class Java::org.apache.hadoop.hbase.HBaseConfiguration

def jbytes( str )
  str.to_java_bytes
end

# Configuration
conf = HBaseConfiguration.new
table = HTable.new(conf, "data")
row = jbytes("row_x")
p = Put.new(row)
p.add(jbytes("raw"), jbytes("csv"), jbytes("1,1,1,1"))
table.put(p)
# Now fetch it back.
g = Get.new(row)
res = table.get(g)
data = res.getValue(jbytes("raw"), jbytes("csv"))
data_s = String.from_java_bytes data
print "The fetched row contains the value '#{data_s}'"

can some one let me know how to execute jruby-hbase-round-trip.rb, what i am trying is as mention below:-

./environment.sh (I have added one more jar to Classpath - jruby-complete-1.1.1.jar )

jruby -S jrubyc jruby-hbase-round-trip.rb

The above commands gives below error:-

java org.jruby.Main jruby-hbase-round-trip

Error opening script file: /jruby-hbase-round-trip (No such file or directory)

any pointers??
