Release: AWS SDK for Java 1.3.22

Web page redirects enable you to change the Uniform Resource Locator (URL) of a web page on your Amazon S3 hosted website (e.g., from www.example.com/oldpage to www.example.com/newpage) without breaking links or bookmarks pointing to the old URL.

For more information, see Hosting Websites on Amazon S3 in the Amazon S3 developer guide.

The SDK now provides a new way to call service operations asynchronously. In addition to the existing asynchronous methods using Java Futures, you can now call asynchronous methods and pass in a very simple callback interface for the SDK to automatically run when your asynchronous operation completes.

The following code creates a new asynchronous Amazon DynamoDB client, then executes an asynchronous request to describe a DynamoDB table. A handler is passed to the async operation, and when the call completes, the SDK will call the onSuccess method, which updates a label in our UI with the table's status. Note that this code doesn't have to poll anything to see when the operation has completed. It simply gives the SDK a handler to invoke when the operation completes, and then continues executing.

	AmazonDynamoDBAsync dynamoDB = new AmazonDynamoDBAsyncClient(myCredentials);
	dynamoDB.describeTableAsync(new DescribeTableRequest().withTableName(myTableName),
	new AsyncHandler() {
		public void onSuccess(DescribeTableRequest request, DescribeTableResult result) {
			myTableStatusLabel.setText(result.getTable().getTableStatus());
		}

		public void onError(Exception exception) {
			// Callers can also test if exception is an instance of
			// AmazonServiceException or AmazonClientException and cast
			// it to get additional information
			System.out.println("Error describing table: " + exception.getMessage());
		}
	});
	// Continue processing without blocking the current thread
