undefined method 'gsub' for #

Question

I keep getting this error when running my script. I'm quite new to Ruby so pleaes excuse my arrogance.

I'm scripting with Nuix which has JRuby support built in.

This is my code;

require 'benchmark'
require 'socket'
require 'rubygems'
require 'java'

java_import org.joda.time.format.DateTimeFormat

    module JSwing
      include_package javax.swing
    end

    def dropdown()

        ar = Array.new

        $current_case.getRootItems().each do set
        ar  set.guid()
        end

        names2 = JSwingJOptionPane.showInputDialog(nil, Please enter the name of the item set to export to Relativity., 
                                                            Choose item set, -1, 
                                                            nil, ar.to_java(Object), ar[0])
        if (names2.nil)
        JSwingJOptionPane.showMessageDialog(nil, No Export Set Selected)
            abort()
            end
        return names2
    end

    def writeLine (filepath, line)
        File.open(filepath, 'a') { f1 f1.puts line }
    end 

    def writeLines(filepath, lines)

        #lines.each do output

        }

      end
    end

    threads2.each do t
        t.join
    end
    bench.report(Write Lines n){
        #writeLinesUTF($path, sharedarray)
    }
    #frame.dispose

}







#end
end

return

And this is the exception that keeps getting thrown;

undefined method `gsub' for #<#<Class:0x45716032>:0x13685969>
["<script>:194:in `(root)'", "org/jruby/ext/thread/Mutex.java:149:in `synchronize'", "<script>:142:in `(root)'"]

I believe it might be being thrown on the checknull function, however I cannot be certain.

Any help is appreciated.

Thanks

Answer 1

Before using 'gsub' on a string try using 'to_s' just before that to convert it to string if it isn't a string. Something like this:

something.to_s.gsub(...)
