(Java) Glacier Upload Archive

Demonstrates how to add an archive to a vault. For a successful upload, your data is durably persisted. In response, Amazon S3 Glacier (Glacier) returns the archive ID in the x-amz-archive-id header of the response. You should save the archive ID returned so that you can access the archive later.

Note: This example requires Chilkat v9.5.0.78 or greater.
