I have a local and custom implementation of an AWS infrastructure.

I use a Grizzley server to back my system. When I start it I have a bucket called "fake". This is the way I do it using AWS CLI:

aws --endpoint-url="http:127.0.0.1:8080" s3 FILE_PATH s3://fake

This works perfectly. My question is now how can I upload a file to that bucket using JAVA and not using the CLI?
