the tutorial uses package aws.example.helloswf, but later, the templating system resolves this as example.swf.hello.

the example code directory is just structured differently than the user's directory because of the way the mvn project is initialized.

From Gitter: http://docs.aws.amazon.com/AmazonS3/latest/dev/HLTrackProgressMPUJava.html uses PutObjectRequest.setProgressListener, which is deprecated. The correct method is setGeneralProgressListener (or withGeneralProgressListener), and a different ProgressListener and ProgressEvent implementation should be used that is not S3-specific.

The sdk samples take you to master which has the Builder API which was not available to me, the documentation needs to point to the rightv version of the documentation which one can use with scala.

This did not work: https://github.com/aws/aws-sdk-java/tree/master/src/samples

This worked: https://github.com/aws/aws-sdk-java/tree/1.11.22/src/samples

Also, the scala example is out of date. Please update the docs as they are very misleading and not beginner friendly https://aws.amazon.com/blogs/compute/writing-aws-lambda-functions-in-scala/

I'm currently in the process of creating a SWF with multiple Lambda functions as activities. Can you provide an example/documentation on how to achieve this. I have searched a lot for how Lambda functions can be scheduled using deciders but couldn't find any.

Basically, In my case, The input to the Workflow (from the WorkFlowStarter) determines which Lambda function to be executed first. Thereafter, the result of a Lambda function determines which Lambda function to be executed next. An example (in Java) would be helpful.

It seems like something is going on with the parsing of this document into this page.

The last lines of these generated code snippets are missing:

After reading about the DynamoDBMapper, I figured my DynamoDB implementation was lacking.

I'm really interested to see best practices of implementing a DynamoDB class with Put and Get item functions. Is the DynamoDBMapper the best way to do it or is it better to implement without all the annotations? What are the advantages / disadvantages?

Thank you!

Hi,

I would be happy if there is an example with Fargate.
Preferable it should list all the S3-buckets from the container.

I am currently struggling with the AwsCredentialProvider.

Thank you!

Hello,
I really like your topics and the way you explain. I am a computer science student. I am developing an desktop app that would help farmers get to know the best seed for the area based on the database of experts. I did that well but I also wanted them to be updated on what to do every time there has to be an activity on their crops for instance weed, apply fertilizer etc. I have a table of timing which stores duration for a given crop and what my program does it subtract the starting date as the planting date from the current date and checks from the timing table if the differences in dates matches the duration stored for the crop it fetches the action. I have tried doing a thread but it is not fetching the action. Kindly this is the section of the code.
String selcted_crop = crop();
String selcted_place = activity_Area();

try {
    String s = "Insert into activities(id_Number, f_Name, l_Name, phone_Number, start_Date, crop_ID, place_ID, farm_Size)values(?,?,?,?,?,?,?,?) ";

On the swf-basics page, we see:

AmazonSimpleWorkflowClient swf = AmazonSimpleWorkflowClientBuilder.defaultClient();

This won't compile, since AmazonSimpleWorkflowClientBuilder.defaultClient() is declared to return an instance of AmazonSimpleWorkflow, which isn't compile-time guaranteed to be an AmazonSimpleWorkflowClient instance.

Hi,

Has anyone tried using AmazonS3EncryptionClient with TransferUtility?

Irrespective of the chosen CryptoConfiguration, when ObjectMetadata.addUserMetadata is internally called during the building of the putobject request, an exception is raised, which is apparently the result of ObjectMetadata.usermetadata being an UnmodifiableMap, which makes it impossible to add the required custom meta data:

When using AmazonS3EncryptionClient.putObject directly (not using TransferUtility), such an error does not happen.

This is urgent.

Here is the exception:

java.lang.UnsupportedOperationException

In the file doc_source/s3-encryption-migration.md it suggests to use withRangeGetMode(CryptoRangeGetMode.ALL) for multipart downloads using Amazon S3 TransferManager. But CryptoRangeGetMode.ALL shows it is deprecated. What is the reason behind it and what is alternative to perform multipart downloads using Amazon S3 TransferManager?

The SWF Developer Guide contains a broken link to the Java specific SWF developer guide.

It can be found under the SDK's section:

• AWS Java Developer Guide | Amazon SWF

From this page: https://github.com/awsdocs/aws-java-developer-guide/blob/master/doc_source/setup-project-maven.rst

I have tried importing the entire SDK with

<dependencies>
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk</artifactId>
    </dependency>
</dependencies>

But get an error that I must specify a version.

If I specify a version, this dependency works, but that defeats the purpose of the BOM.

Is it possible to import the whole SDK using the BOM?

For reference, BOM:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.amazonaws</groupId>
      <artifactId>aws-java-sdk-bom</artifactId>
      <version>1.11.22</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

Since Gradle 4.6 it is possible to use Gradle's improved POM support feature for importing bill of materials files by simply declaring a dependency on a BOM.

The code shown under "How to Tag Your Spot Requests and Instances" is incorrect. It currently shows how to Cancel or Terminate instances, not tag them.

This is in https://github.com/awsdocs/aws-java-developer-guide/blob/master/doc_source/tutorial-spot-adv-java.rst

Similar to #19 - throughout the hello-world docs, the imported source code is resolving to the wrong lines. It looks like there are just hard-coded line numbers here (literal-includes); but the underlying source code is changing regularly. Linking to fixed line numbers in a remote living-document doesn't seem like a winning strategy.

2.0：https://docs.aws.amazon.com/zh_cn/sdk-for-java/v2/developer-guide/advanced-topics.html
but I can find it at 1.0 https://docs.aws.amazon.com/zh_cn/sdk-for-java/v1/developer-guide/prog-services-sts.html

is 2.0 not support for STS？
