This project provides a client library in Java that makes it easy to consume Windows Azure Storage services. For documentation please see the Windows Azure Java Developer Center and the JavaDocs.
#Features
- Blob
- Create/Read/Update/Delete containers
- Create/Read/Update/Delete blobs
- Queue
- Create/Delete Queues
- Insert/Peek Queue Messages
- Advanced Queue Operations
- Table
- Create/Read/Update/Delete tables

- Batch operation
#Getting Started
##Download ###Option 1: Via Git
To get the source code of the SDK via git just type:
git clone git://github.com/WindowsAzure/azure-storage-java.git
cd ./azure-storage-java/microsoft-azure-storage
mvn compile
###Option 2: Via Maven
To get the binaries of this library as distributed by Microsoft, ready for use within your project you can also have them installed by the Java package manager Maven.
<dependency>
<groupId>com.microsoft.windowsazure.storage</groupId>
<artifactId>microsoft-windowsazure-storage-sdk</artifactId>
<version>0.5.0</version>
</dependency>##Minimum Requirements
- Java 1.6
- (Optional) Maven
##Usage
To use this SDK to call Windows Azure services, you need to first create an account. To host your Java code in Windows Azure, you additionally need to download the full Windows Azure SDK for Java - which includes packaging, emulation, and deployment tools.
##Code Sample
The following is a quick example on how to set up a Azure blob using the API and uploading a file to it. For additional information on using the client libraries to access Azure services see the How To guides for blobs, queues and tables and the general documentation.
import java.io.*;
import com.microsoft.windowsazure.storage.*;
import com.microsoft.windowsazure.storage.blob.*;
public class BlobSample {
public static final String storageConnectionString =
"DefaultEndpointsProtocol=http;"
+ "AccountName=your_account_name;"
+ "AccountKey= your_account_key";
public static void main(String[] args) {
try {
CloudStorageAccount account;
CloudBlobClient serviceClient;
CloudBlobContainer container;
CloudBlockBlob blob;
account = CloudStorageAccount.parse(storageConnectionString);
serviceClient = account.createCloudBlobClient();
// Container name must be lower case.
container = serviceClient.getContainerReference("blobsample");
container.createIfNotExists();
// Set anonymous access on the container.
BlobContainerPermissions containerPermissions;
containerPermissions = new BlobContainerPermissions();
container.uploadPermissions(containerPermissions);
// Upload an image file.
blob = container.getBlockBlobReference("image1.jpg");
File fileReference = new File("c:\\myimages\\image1.jpg");
blob.upload(new FileInputStream(fileReference), fileReference.length());
} catch (FileNotFoundException fileNotFoundException) {
System.out.print("FileNotFoundException encountered: ");
System.out.println(fileNotFoundException.getMessage());
System.exit(-1);
} catch (StorageException storageException) {
System.out.print("StorageException encountered: ");
System.out.println(storageException.getMessage());
System.exit(-1);
} catch (Exception e) {
System.out.print("Exception encountered: ");
System.out.println(e.getMessage());
System.exit(-1);
}
}
