MS Word processing or parsing using ruby and Apache POI

I am looking for MS word document processing to get text information using ruby. But could not find right gems in ruby. Some win32 ole libraries are there but will not work in linux. So thought about using Poi java api to process word document.

I hv downloded poi jar files from here.
http://www.apache.org/dyn/closer.cgi/poi/release/

changed the name of the directory to poi folder .

Check the following ruby script to get the parsed text .. it uses java interface code in WordSampleReader.java   this file should be compiled and should be available under poi folder where all jar files are there.

CONFIG = {}
class WordReader
  #include Config
  CONFIG['host'] = 'mswin32'
  def self.generate_text(filename)
   
    interface_classpath=Dir.getwd+"/poi"
  
    case CONFIG['host']
      when /mswin32/
        Dir.foreach("poi") do |file|
          interface_classpath << ";#{Dir.getwd}/poi/"+file if (file != '.' and file != '..' and file.match(/.jar/))
        end
        path = "java -cp \"#{interface_classpath}\" WordSampleReader "+filename
      else
        Dir.foreach(Dir.getwd+"/poi/") do |file|
          interface_classpath << ":#{Dir.getwd}/poi/"+file if (file != '.' and file != '..' and file.match(/.jar/)) 
        end
        path = "java -cp \"#{interface_classpath}\" WordSampleReader "+filename
      end
    result = ""
    IO.popen(path, "w+b" ) { |x| result= x.read }
    result
  end
end

puts reader = WordReader.generate_text('poi/test.doc')


Though i dont know java used sample code found in google..  The file called WordSampleReader.java.

The source code file is ...

//package com.informit.poi;

// Import POI classes
import org.apache.poi.poifs.filesystem.*;
import org.apache.poi.hwpf.*;
import org.apache.poi.hwpf.extractor.*;

// Import Java classes
import java.io.*;
import java.util.*;

public class WordSampleReader
{
  public static void main( String[] args )
  {
   if( args.length == 0 )
   {
     System.out.println( "Usage: WordSampleReader " );
     System.exit( 0 );
   }

   String filename = args[ 0 ];
   try
   {
     // Create a POI File System object; this is the main class for the POIFS file system
     // and it manages the entire lifecycle of the file system
     POIFSFileSystem fs = new POIFSFileSystem( new FileInputStream( filename ) );

     // Create a document for this file
     HWPFDocument doc = new HWPFDocument( fs );

     // Create a WordExtractor to read the text of the word document
     WordExtractor we = new WordExtractor( doc );
    
     // Extract all paragraphs in the document as strings
     String[] paragraphs = we.getParagraphText();

     // Output the document
     //System.out.println( "Word Document has " + paragraphs.length + " paragraphs" );
    // for( int i=0; i
     //{
      //System.out.println( paragraphs[ i ] );
     //}
    //  output text
      System.out.println( we.getText() );

   }
   catch( Exception e )
   {
     e.printStackTrace();
   }
  }
}
