Write To file with getResource

Question

I use This methods to Write to a text file(use getResource()... to use in JAR file). My files are in Classpath, Here is my code:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;

public class JarWrite {

    public JarWrite(){
        writethis();
    }

    public void writethis(){

        try{
       InputStreamReader isReader=  new InputStreamReader(this.getClass().getResourceAsStream("AllBookRecords.txt"));
      BufferedReader br = new BufferedReader(isReader);

      PrintWriter writer1=new PrintWriter(new File(this.getClass().getResource("Boutput.txt").getPath()));

      String Bs;
            while( (Bs=br.readLine()) != null ){                 
                    writer1.println(Bs);               
            }

            writer1.close();
            br.close();

        } catch(FileNotFoundException fnfe){

        } catch(IOException ioe){
            ioe.printStackTrace();
        }
    }

    public static void main(String[] args){
        new JarWrite();
    }    
    }

You can't modify resources from CLASSPATH. They are read only. Period.

See also: Java OutputStream equivalent to getClass().getClassLoader().getResourceAsStream().

@Sajjad-himorning: just use standard `FileWriter` and file system? – Tomasz Nurkiewicz Jan 22 '13 at 12:47

Try changing:

public void writethis

to

public static void writethis

... and that will not compile because in the first line there is a reference for `this.getClass()` – gaborsch Jan 21 '13 at 21:00
