Prerequisites

• Java 1.5 (http://java.sun.com/)

Package Content

Quick Start

1. Extract the amazon-ec2-2009-11-30-java-library.zip file into a working directory.
2. Add all sources under "src" directory to your compilation path.
3. Add all jars files under "third-party/*" directory to your classpath
4. Edit desired sample. For example: DescribeImagesSample.java



• Set AWS Access Key ID and AWS Secret Access Key

String accessKeyId = "Your Access Key ID";
String secretAccessKey = "Your Secret Access Key";
                




• Set request parameters. For example, find following pre-generated snippet:

DescribeImagesRequest request = new DescribeImagesRequest();
// @TODO: set request parameters here
// invokeDescribeImages(service, request);
                




• And uncomment third line and add:

DescribeImagesRequest request = new DescribeImagesRequest()
                                    .withImageId("ami-be3adfd7");
invokeDescribeImages(service, request);
                



5. Compile and run DescribeImagesSample. You should see the output similar to the following:




    DescribeImagesResponse
        DescribeImagesResult
            Image
                ImageId
                    ami-be3adfd7
                ImageLocation
                    ec2-public-images/fedora-8-i386-base-v1.04.manifest.xml
                ImageState
                    available
                KernelId
                    aki-4438dd2d
                RamdiskId
                    ari-4538dd2c
                ...

            



Note, to see additional debugging output, adjust level of debugging in log4j.properties available in the root of the source tree.


6. Experiment with samples. When ready, add library binary distribution to your application classpath, and use it.

Making Requests to a Different Region

To make the service call to a different region, instantiate the client with the configuration object, and pass the region-specific endpoint. For example:

    AmazonEC2Config ec2Config = new AmazonEC2Config()
    	.withServiceURL("https://eu-west-1.ec2.amazonaws.com"));        
    AmazonSimpleDB service = new AmazonEC2Client(accessKeyId, secretAccessKey, ec2Config); 

Please see the Amazon EC2 Developer Guide for a complete list of region endpoints.
