[JAVA] Problema nel copiare Jar innestati

[anx721]

non puoi copiare i file binari come file di testo, interpretando quindi i byte come dei char.

import java.io.*;

public void copy(String originalFile, String newFile) throws IOException {
    File inputFile = new File(originalFile);
    File outputFile = new File(newFile);
    InputStream finput = new BufferedInputStream(new FileInputStream(inputFile));
    OutputStream foutput = new BufferedOutputStream( new FileOutputStream(outputFile));
    byte[] buffer = new byte[1024 * 500];
    int bytes_letti = 0;
    while((bytes_letti = finput.read(buffer)) > 0)
        foutput.write(buffer, 0, bytes_letti);
    finput.close();
    foutput.close();
} 

oppure

import java.nio.channels.*;
import java.io.*;


  public void copyFile(File sfile, File dfile) throws Exception
  {
     FileChannel source = new FileInputStream(sfile).getChannel();
     FileChannel dest = new  FileOutputStream(dfile).getChannel();
     source.transferTo(0, source.size(), dest);
     source.close();
     dest.close();
  }
