Create your Application

We'll now build the application that will run on the Amazon EC2 instance. First, create a directory that

you can use to hold your tutorial files. Call it something like GetS3ObjectApp.

Next, copy the SDK for Java libraries into your newly-created tutorial directory. If you downloaded the

SDK for Java to your ~/Downloads directory, you can copy them with the following commands:

cp -r ~/Downloads/aws-java-sdk-1.7.5/lib .

cp -r ~/Downloads/aws-java-sdk-1.7.5/third-party .

Here is the program that we'll be transferring to your EC2 instance. Open a new file, call it

GetS3Ojbect.java, and type (or paste) the following code:

import java.io.*;

import com.amazonaws.auth.*;

import com.amazonaws.services.s3.*;

import com.amazonaws.services.s3.model.*;

import com.amazonaws.AmazonClientException;

import com.amazonaws.AmazonServiceException;

public class GetS3Object {

private static String bucketName = "text-content";

private static String key = "text-object.txt";

public static void main(String[] args) throws IOException

{

AmazonS3 s3Client = new AmazonS3Client();

try
