Uploading a Public File to Amazon S3 using the Java API

Amazon’s S3 sample doesn’t show how to upload a file and make it public at the same time. Set the ACL as shown.


PutObjectRequest por = new PutObjectRequest(bucketName, key, file);
por.setCannedAcl(CannedAccessControlList.PublicRead);
s3.putObject(por);
