Question

String inFileName = testDoc.gz;

File inFile = new File(inFileName);
System.out.println(inFileName);
FileInputStream fileStream = new FileInputStream(inFile);
GZIPInputStream gzipInputStream = new GZIPInputStream(fileStream);

When executing the above code in the the last line returns the error:

java.io.IOException: Not in GZIP format

I have tried it with multiple documents and cannot see the problem.

EDIT: The documents were not created by me, they are downloaded. They are in the .gz format and by multiple documents I mean different .gz files.

Answer 1

You could try mounting the GZIP file with VFS.
