Extract A tar.gz file

Question

Ok guys,
I have a program that extracts the contents of a tar.gz file. Right now it does extract one of the files and then throws an error:
com.ice.tar.InvalidHeaderException: bad header in block 9 record 10, header magi
c is not 'ustar' or unix-style zeros, it is '1141115144674854', or (dec) 114, 11

        at com.ice.tar.TarInputStream.getNextEntry(Unknown Source)
        at Extract_TAR_GZ_FILE.untar(Extract_TAR_GZ_FILE.java:37)
        at Extract_TAR_GZ_FILE.run(Extract_TAR_GZ_FILE.java:55)
        at Extract_TAR_GZ_FILE.main(Extract_TAR_GZ_FILE.java:67)
bad header in block 9 record 10, header magic is not 'ustar' or unix-style zeros
, it is '1141115144674854', or (dec) 114, 111, 51, 44, 67, 48, 54 The class that extracts the files:
import java.io.*;
import com.ice.tar.*;
import javax.activation.*;
import java.util.zip.GZIPInputStream;
public class Extract_TAR_GZ_FILE {
     public static InputStream getInputStream(String tarFileName) throws Exception{
      if(tarFileName.substring(tarFileName.lastIndexOf(".") + 1, tarFileName.lastIndexOf(".") + 3).equalsIgnoreCase("gz")){
         System.out.println("Creating an GZIPInputStream for the file");
         return new GZIPInputStream(new FileInputStream(new File(tarFileName)));
      }else{
         System.out.println("Creating an InputStream for the file");
         return new FileInputStream(new File(tarFileName));
     private static void untar(InputStream in, String untarDir) throws IOException {
       System.out.println("Reading TarInputStream... (using classes from http://www.trustice.com/java/tar/)");
      TarInputStream tin = new TarInputStream(in);
      TarEntry tarEntry = tin.getNextEntry();
      if(new File(untarDir).exists()){
           while (tarEntry != null){
              File destPath = new File(untarDir + File.separatorChar + tarEntry.getName());
              System.out.println("Processing " + destPath.getAbsoluteFile());
              if(!tarEntry.isDirectory()){
                 FileOutputStream fout = new FileOutputStream(destPath);
                 tin.copyEntryContents(fout);
                 fout.close();
              }else{
                 destPath.mkdir();
              tarEntry = tin.getNextEntry();
           tin.close();
      }else{
         System.out.println("That destination directory doesn't exist! " + untarDir);
     private void run(){
          try {               
               String strSourceFile = "G:/source/BROKERH_20080303_A2008_S0039.TAR.GZ";
               String strDest = "G:/source/Extracted Files";
               InputStream in = getInputStream(strSourceFile);
               untar(in, strDest);          
          }catch(Exception e) {
               e.printStackTrace();          
               System.out.println(e.getMessage());
     public static void main(String[] strArgs) throws IOException{
          new Extract_TAR_GZ_FILE().run();
}The file I tested with can be found here:

Any help? Thanks a bunch.

Answer 1

I fixed the problem. It was the ftp transfer of files program which wasn't set to BINARY mode. I edited that program and then rerun the above class and boom.. It worked.
Thank you guys for responses.Great! Glad you got it working.
