        var accessKey = System.Configuration.ConfigurationManager.AppSettings["AWSAccessKey"];

        client = new AmazonDynamoDBClient(accessKey, secretAccessKey, config);
    }
}

Solution

You need to run the java command so that -Djava.library.path refers to the path under which you extracted the Local DynamoDB package. The . in -Djava.library.path=. means "the current directory", and the app needs to be able to load the native SQLite libraries in the Local DynamoDB directory.

So you can either run this command from within the local DynamoDB directory:

java -Djava.library.path=. -jar DynamoDBLocal.jar

or you have to give the full path to both:

java -Djava.library.path=c:\path\to\dynamodb\ -jar c:\path\to\dynamodb\DynamoDBLocal.jar

IntelliJ

If you're running a configuration in IntellJ, you can add the jar using the dialog Edit Configurations | Modify Options | Modify classpath, and add the path to the jar there.
