By default, the Event Hubs SDK client library uses the highest available version on Azure ( at the time of the release of the SDK). If you are using Azure Blob Storage as a checkpoint store, check the supported Azure Storage API version for your Azure Stack Hub build and target that version in your code.įor example, If you are running on Azure Stack Hub version 2005, the highest available version for the Storage service is version. Azure Stack Hub may support a different version of Azure Blob Storage SDK than those typically available on Azure. That's because the Event Hubs SDK uses the latest available Azure Storage API available in Azure that may not be available on your Azure Stack Hub platform. If you run this code on Azure Stack Hub, you will experience runtime errors unless you target a specific Storage API version. The code in this tutorial is based on the EventProcessorClient sample on GitHub, which you can examine to see the full working application. You'll run this program after you run the receiver program. ![]() send the last batch of remaining eventsīuild the program, and ensure that there are no errors. Throw new IllegalArgumentException("Event is too large for an empty batch.

Update with the connection string to your Event Hubs namespace. The Java client library for Event Hubs is available in the Maven Central Repository. Update the pom.xml file with the following dependency. Add reference to Azure Event Hubs libraryįirst, create a new Maven project for a console/shell application in your favorite Java development environment. This section shows you how to create a Java application to send events an event hub. You use the connection string later in this quickstart. Then, get the connection string for the Event Hubs namespace by following instructions from the article: Get connection string. ![]() To create a namespace and an event hub, follow the procedure in this article. ![]() The first step is to use the Azure portal to create a namespace of type Event Hubs, and obtain the management credentials your application needs to communicate with the event hub. Create an Event Hubs namespace and an event hub.Java Development Kit (JDK) with version 8 or above is required. ![]() If you don't have an existing Azure account, you can sign up for a free trial or use your MSDN subscriber benefits when you create an account. To use Azure services, including Azure Event Hubs, you need a subscription. To complete this quickstart, you need the following prerequisites: If you're new to Azure Event Hubs, see Event Hubs overview before you do this quickstart. For a quickstart that uses the old azure-eventhubs and azure-eventhubs-eph packages, see Send and receive events using azure-eventhubs and azure-eventhubs-eph. This quickstart uses the new azure-messaging-eventhubs package.
