[jira] [Created] (COMPRESS-511) Decompress tar failed.
java.io.IOException: Error detected parsing the header
Akhila Mangipudi created COMPRESS-511:
-----------------------------------------
Summary: Decompress tar failed. java.io.IOException: Error detected parsing the header
Key: COMPRESS-511
URL: https://issues.apache.org/jira/browse/COMPRESS-511
Project: Commons Compress
Issue Type: Bug
Components: Archivers
Affects Versions: 1.20
Reporter: Akhila Mangipudi
Attachments: layer1.tar
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:
[ec2-user@ip-172-31-16-85 src]$ java TarToByteArray.java layer1.tar
Error: Could not find or load main class TarToByteArray.java
[ec2-user@ip-172-31-16-85 src]$ java TarToByteArray layer1.tar

Also attaching the tar file that I am using!
