Connect to RabbitMQ Data in NetBeans

The CData JDBC Driver for RabbitMQ integrates connectivity to live RabbitMQ data in IDEs that support JDBC. The JDBC standard enables you to use built-in data access wizards and other tools supporting rapid development. This article shows how to connect to RabbitMQ data in NetBeans. You will create a connection and load RabbitMQ data in the Table Editor.

Create a JDBC Data Source for RabbitMQ in NetBeans

To create the JDBC data source, expand the Database node in the Service window, right-click the Drivers node, and select New Driver. In the New Driver wizard that results, enter the following information:

• Driver File(s): Click Add and, in the file explorer dialog that appears, select the cdata.jdbc.api.jar file. The driver JAR is located in the lib subfolder of the installation directory.
• Driver Class: Click Find to search for the driver class inside the JAR. Then select cdata.jdbc.api.APIDriver from the menu.
• Name: Enter the name for the driver.

Define Connection Parameters

Follow the steps below to define required connection properties:

1. In the Service window, right-click the Database node and click New Connection.

2. In the New Connection Wizard, enter the following connection properties:

   • Driver Name: In the menu, select the CData JDBC Driver for RabbitMQ.
   • User Name: Enter the username. This can also be defined in the JDBC URL.
   • Password: Enter the password. This can also be defined in the JDBC URL.

   • JDBC URL: Specify the JDBC URL.

     About RabbitMQ Management HTTP API

     RabbitMQ is an open-source message broker that supports multiple messaging protocols. The RabbitMQ Management HTTP API provides HTTP-based access to management and monitoring data for a RabbitMQ server. The API exposes information about virtual hosts, exchanges, queues, bindings, connections, channels, consumers, users, permissions, policies, and cluster-wide statistics.

     The Management plugin must be enabled on the RabbitMQ server for the HTTP API to be available. By default, the management interface listens on port 15672.

     Using Basic Authentication

     RabbitMQ Management HTTP API uses HTTP Basic authentication. You must supply the username and password of a RabbitMQ management user.

     To enable access to the management API:

     1. Ensure the RabbitMQ Management plugin is enabled on your server (rabbitmq-plugins enable rabbitmq_management).
     2. Use an existing management user or create one with the appropriate management tag (management, policymaker, monitoring, or administrator).
     3. Note the full base URL of your RabbitMQ Management HTTP API (e.g., http://localhost:15672).

     After configuring your RabbitMQ server, set the following connection properties to connect:

     • AuthScheme: Set this to Basic.
     • URL: Set this to the base URL of your RabbitMQ Management HTTP API (e.g., http://localhost:15672).
     • User: Set this to your RabbitMQ management username (e.g., guest).
     • Password: Set this to your RabbitMQ management password.

     Example connection string:

     Profile=C:\profiles\RabbitMQ.apip;AuthScheme=Basic;URL=http://localhost:15672;User=guest;Password=guest;
     

     Available Tables

     The RabbitMQ profile provides access to the following tables:

     • Overview - Cluster-wide statistics and information about the RabbitMQ node
     • Nodes - Information about individual nodes in the RabbitMQ cluster
     • NodeMemory - Detailed memory usage breakdown for a specific cluster node
     • Connections - List of all open AMQP connections to the broker
     • Channels - List of all open AMQP channels across all connections
     • Consumers - List of all consumers registered across all queues
     • Exchanges - List of exchanges declared across all virtual hosts
     • Queues - List of queues declared across all virtual hosts
     • Bindings - List of all bindings between exchanges and queues
     • VirtualHosts - List of virtual hosts configured on the broker
     • VhostPermissions - User permissions within a specific virtual host
     • Users - List of all RabbitMQ users
     • Permissions - Permission records for all users across all virtual hosts
     • TopicPermissions - Topic-level permission records for all users
     • Policies - List of policies applied to queues and exchanges in virtual hosts
     • OperatorPolicies - List of operator policies applied to queues in virtual hosts
     • Parameters - List of component parameters (e.g., federation, shovel) per virtual host
     • GlobalParameters - List of global parameters that apply across all virtual hosts
     • VhostLimits - Resource limits configured for specific virtual hosts
     • UserLimits - Resource limits configured for specific users
     • FeatureFlags - List of feature flags and their enabled/disabled state on the node
     • DeprecatedFeatures - List of deprecated features and their usage state
     • AuthAttempts - Authentication attempt statistics for the node
     • ClusterName - The name of the RabbitMQ cluster
     • WhoAmI - Information about the currently authenticated management user
     • ExchangeBindingsSource - Bindings for which a specific exchange is the source
     • ExchangeBindingsDestination - Bindings for which a specific exchange is the destination
     • QueueBindings - Bindings for a specific queue within a virtual host

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the RabbitMQ JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.api.jar
     

     Fill in the connection properties and copy the connection string to the clipboard.

     

     A typical JDBC URL is the following:

     jdbc:api:Profile=C:\profiles\\RabbitMQ.apip;AuthScheme=Basic;URL=http://localhost:15672;User=guest;Password=guest;

Query RabbitMQ Data

To connect to RabbitMQ data, right-click the connection in the Database node and click Connect. After the connection is established, you can expand it to discover schema information.

To load a table in the Data Views window, right-click the table and then click View Data..
