# Using aws-lambda-java-core

This package defines the Lambda [Context](http://docs.aws.amazon.com/lambda/latest/dg/java-context-object.html)
object as well as [interfaces](http://docs.aws.amazon.com/lambda/latest/dg/java-handler-using-predefined-interfaces.html) that Lambda accepts.

# Using aws-lambda-java-events

This package defines [event sources](http://docs.aws.amazon.com/lambda/latest/dg/intro-invocation-modes.html) that AWS Lambda natively accepts. See the [documentation](https://github.com/aws/aws-lambda-java-libs/tree/master/aws-lambda-java-events) for more information.

# Using aws-lambda-java-log4j2

This package defines the Lambda adapter to use with log4j version 2. See
[documentation](https://github.com/aws/aws-lambda-java-libs/tree/master/aws-lambda-java-log4j2) for how to use the adapter.

# Using aws-lambda-java-log4j (Not recommended)

This package defines the Lambda adapter to use with log4j version 1. See
the [official documentation](http://docs.aws.amazon.com/lambda/latest/dg/java-logging.html#java-wt-logging-using-log4j) for how to use this adapter.
