Apache Tika – PrintWriter works on local Windows machine but not Linux box

I’m stumped. This script works great in Eclipse on my windows machine, if I hard code the file paths. If I try to take in arguments and run it on my edge node (a linux box), it throws no particular errors but it just leaves an empty output file. I must be missing something stupid, but I am not seeing it. Anyone have any idea what’s going on?

package com.trv.cbia.de.tika;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;

import java.util.Map;


public class DocParser {

public Map<String, Object> processRecord(String path) {
    Map<String, Object> map = new HashMap<String, Object>();
    String docPath = path;
    try{
            BodyContentHandler handler = new BodyContentHandler();
            Metadata metadata = new Metadata();
            InputStream inputstream = new FileInputStream(new File(docPath));
            ParseContext pcontext = new ParseContext();
            Parser pdfparser  = new AutoDetectParser();
            pdfparser.parse(inputstream, handler, metadata, pcontext);
            map.put("text", handler.toString().replaceAll("n|r|t", " "));
             map.put("title", metadata.get(TikaCoreProperties.TITLE));
             map.put("pageCount", metadata.get("xmpTPg:NPages"));

    } catch (IOException ex){
         System.out.println("Caught IOException:" + ex.getMessage());
    }
    catch(TikaException tx) {
         System.out.println("Caught TikaException: " + tx.getMessage());
    }
    catch(SAXException sx){

         System.out.println("Caught SAXException: " + sx.getMessage());

        }

    return map;
}

 public static void main(String args[]){


    String file = args[0];
    String out =  args[1];
    DocParser textExtract = new DocParser();
    Map<String, Object> extractedMap = textExtract.processRecord(file);
    try {
        PrintWriter writer = new PrintWriter(out,"UTF-8");
        writer.println(extractedMap.get("text"));
        writer.flush();
        writer.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

}

}

Answer

Ended up being that I needed to add tika-app-1.13.jar to my classpath. It never divulged any classpath errors. I had to dig through a bunch of the apache mailing list to find someone with a similar problem. Posting the solution here in case anyone else runs across it.
