Sample project to demonstrate usage of the AWS SDK for Java

AWS SDK for Java Sample Project

A simple Java application illustrating usage of the AWS SDK for Java.

Requirements

You have a choice of Maven or Gradle

The only requirement of this application is Maven. All other dependencies can be installed by building the maven package:

mvn package

Otherwise with gradle you can run the gradlew wrapper and all dependencies will be installed:

gradlew build

Basic Configuration

You need to set up your AWS security credentials before the sample code is able to connect to AWS. You can do this by creating a file named "credentials" at ~/.aws/ (C:\Users\USER_NAME.aws\ for Windows users) and saving the following lines in the file:

[default]
aws_access_key_id = <your access key id>
aws_secret_access_key = <your secret key>

See the Security Credentials page for more information on getting your keys.

Running the S3 sample

Prerequisites

You will need to go to IAM policies page, search for the String "S3," and "Attach" the "AmazonS3FullAccess" policy to the user whose credentials exist in your ~/.aws/credentials file. Otherwise, you will likely get a AmazonServiceException/Access Denied/403 error.

This sample application connects to Amazon's Simple Storage Service (S3), creates a bucket, and uploads a file to that bucket. The code will generate a bucket name for you, as well as an example file to upload. All you need to do is run it.

Maven:

mvn clean compile exec:java

Gradle:

gradlew clean build run

When you start making your own buckets, the S3 documentation provides a good overview of the restrictions for bucket names.

aws-java-sample's Issues

No provision to override httpclient connection timeout value

if request takes too long due to slow connection, request fails.

Caught an AmazonServiceException

When I tried to run this sample, I get this:

Error Message:    Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: <>)
HTTP Status Code: 403
AWS Error Code:   AccessDenied
Error Type:       Client
Request ID:       <>

Any help is appreciated.

pom ref to AwsCredentials.properties: include resources paragraph under build paragraph

AwsCredentials.properties is not found given the current java source and pom, so the sample does not run on Mac OS X.

Given that the keys are global and users may not want to include them in each project, the pom.xml should include the external ~/.aws/ properties directory in the runtime classpath.

For example:

<build>
        <resources>
                <resource>
                        <directory>${env.HOME}/.aws/</directory>
                </resource>
        </resources>

After the opening of the build tag and before the start of the exec-maven-plugin.

${env.HOME} resolves to the developers home dir.

Info in getting started web page wrong

http://aws.amazon.com/developers/getting-started/java/
refers to this sample. However it describes how to make a credentials file in .aws in one's home directory. The sample needs a different format file on the classpath,

Please help !!! Thanks in advance

The AWS Access Key Id you provided does not exist in our records.

It does, and it's properly set up in my ~/.aws/credentials file and it's successfully used by the Javascript SDK and the AWS CLI - and (while it shouldn't make a difference) I changed the region setting in the Java code to be EU-WEST-1 to try that too. Same problem

Given that, what's the problem please?

s3 does not require region selection

Remove line 66 and 67 from S3Sample.java:

        Region usWest2 = Region.getRegion(Regions.US_WEST_2);
        s3.setRegion(usWest2);

Maven error and javax.xml.bind.DatatypeConverter with jdk10

If you get the error
maven Source option 5 is no longer supported. Use 6 or later. [ERROR] Target option 1.5 is no longer supported. Use 1.6 or later.

Add the following to the properties
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>

That fixes the problem for jdk8.

For jdk10
The example builds but gives a runtime exception
An exception occured while executing the Java class. null: InvocationTargetException: javax/xml/bind/DatatypeConverter: javax.xml.bind.DatatypeConverter

as javax.xml.bind.DatatypeConverter is removed in JDK9 onwards

class not found exception when compiling

I'm running Win7 64bit and have installed maven and the Java SDK. When running mvn package the AWS packages are downloaded and everything seems fine.

When I run mvn clean compile exec:java, I end up with this:

What I am doing wrong or missing? Do I need to remove CLASSPATH from my Windows environment variables?

AmazonClientException

I've got some troubles with running this sample.
I've followed instructions on http://aws.amazon.com/ru/developers/getting-started/java/, and after running mvn clean compile exec:java I've got AmazonClientException(Unable to execute HTTP request: peer not authenticated) followed by "Unable to execute HTTP request: peer not authenticated". This things happen when I am trying to create bucket, so I've got "Creating bucket my-first-s3-bucket-865cc23b-7f73-4e09-a9d9-c38382d72e2b" and then an error.
I've looked throw https://forums.aws.amazon.com/message.jspa?messageID=429971, but unfortunately I don't completely understand how to use suggested solution (http://javaskeleton.blogspot.ie/2010/07/avoiding-peer-not-authenticated-with.html) here.

Unable to load AWS credentials from any provider in the chain

I have my application running on EC2. Trying to access dynamoDB from my Java application. But for every operation, I get "Unable to load AWS credentials from any provider in the chain".

• I have added dynamoDB permissions in the IAM role that gets attached to EC2 instance
• And also configured EC2 to assume that role in trust relationship.

Code:

            AWSCredentialsProvider provider = new DefaultAWSCredentialsProviderChain();
            AWSCredentials credentials = provider.getCredentials();
            if(credentials != null) {
                LOG.info("Credentials Key: " + credentials.getAWSAccessKeyId());
                LOG.info("Credentials secret: " + credentials.getAWSSecretKey());
            }
        } catch (Exception e) {
            LOG.info("Exception in credentials cause:" + e.getCause() +";message: " + e.getMessage() +";stack: " +e.getStackTrace());
        }

The getCredentials() line itself throws an Exception with message: "Unable to load AWS credentials from any provider in the chain".
If I do not try to get credentials here and pass it to the DynamoDB client:

                .withClientConfiguration(clientConfig)
                .build();```

Then it throws the same exception when I try to do any operation.

I tried setting up the proxy too: 

```ClientConfiguration clientConfig = new ClientConfiguration();
        clientConfig.setProxyHost("yyy");
        clientConfig.setProxyPort(port);
        clientConfig.setNonProxyHosts("xxx");
        clientConfig.setProtocol(Protocol.HTTP);```

and then passing it while creating the client:

```        dynamoDBClient = builder.withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(url, region.getName()))
                .withCredentials(credentialProvider())
                .withClientConfiguration(clientConfig)
                .build();

But no success.

Can someone @here guide me what am I missing here?
