403 creating java lambda function

Hello,

Cloufront URL are not valid to deploy your Java based AWS Lambda functions. You can upload your zip artifact with the java function in two ways:

1. Upload the zip artifact from your local computer with the console or CLI.
2. Use a S3 bucket location (where you have access) with your artifact in the console or CLI:

aws s3 cp my-function.zip s3://my-bucket

And later:

aws lambda update-function-code --function-name my-function \
 --s3-bucket my-bucket --s3-key my-function.zip

Hope it helps.
