Description

public static void main(String args[]) throws Exception {

//Send the TAR file as an argument
String tarFileName = args[0];

/* Read TAR File into TarArchiveInputStream */
TarArchiveInputStream myTarFile=new TarArchiveInputStream(new FileInputStream(new File(tarFileName)));
/* To read individual TAR file */
TarArchiveEntry entry = null;
String individualFiles;
int offset;
FileOutputStream outputFile=null;
/* Create a loop to read every single entry in TAR file */
while ((entry = myTarFile.getNextTarEntry()) != null)

{ /* Get the name of the file */ individualFiles = entry.getName(); /* Get Size of the file and create a byte array for the size */ byte[] content = new byte[(int) entry.getSize()]; offset=0; /* Some SOP statements to check progress */ System.out.println("File Name in TAR File is: " + individualFiles); System.out.println("Size of the File is: " + entry.getSize()); System.out.println("Byte Array length: " + content.length); /* Read file from the archive into byte array */ myTarFile.read(content, offset, content.length - offset); /* Define OutputStream for writing the file */ outputFile=new FileOutputStream(new File(individualFiles)); }

 

I was able to decompress the tar file in the Linux environment using the tar command. Following is the error when I run the code:

Also attaching the tar file that I am using!
