   What JVM version are you running? It sounds like you might be using an older version without up to date CA certs in your keystore.

   Hey @kiran1920, it sounds like you might need to double-check your AWS security credentials and make sure this sample code is picking them up correctly.

   Have you created the .aws/credentials file in your home directory? It should look something like this:

   [default]
   aws_access_key_id = YOUR_ACCESS_KEY_ID
   aws_secret_access_key = YOUR_SECRET_ACCESS_KEY

   I am trying to run this and am getting the following error Caught an AmazonServiceException, which means your request made it to Amazon S3, but was rejected with an error response for some reason.
   Error Message: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: 3FC6FAECDE3A19A1). I checked my access keys and believe that they are correct. How can I go about researching this further?

   Answering my own question. My permissions were not correct. I needed to give full access to S3.
