To add and configure a connector in Studio: 1. [Create a Mule project](#create-mule-project). 2. [Add the connector to your Mule project](#add-connector-to-project). 3. [Configure a source for the connector’s flow](#configure-input-source). 4. [Add a connector operation to the flow](#add-connector-operation). 5. [Configure a global element for the connector](#configure-global-element). 6. [Configure the connection to a broker](#configure-connection). When you run the connector, you can view the app log to check for problems, as described in [View the App Log](#view-app-log). If you are new to configuring connectors in Studio, see [Using Anypoint Studio to Configure a Connector](https://docs.mulesoft.com/connectors/introduction/intro-config-use-studio). If, after reading this topic, you need additional information about the connector fields, see the [JMS Connector Reference](https://docs.mulesoft.com/jms-connector/1.10/jms-connector-reference). ## Create a Mule Project In Studio, create a new Mule project in which to add and configure the connector: 1. In Studio, select **File > New > Mule Project**. 2. Enter a name for your Mule project and click **Finish**. ## Add the Connector to Your Mule Project Add Anypoint Connector for JMS (JMS Connector) to your Mule project to automatically populate the XML code with the connector’s namespace and schema location and to add the required dependencies to the project’s `pom.xml` file: 1. In the **Mule Palette** view, click **(X) Search in Exchange**. 2. In the **Add Dependencies to Project** window, type `jms` in the search field. 3. Click **JMS Connector** in **Available modules**. 4. Click **Add**. 5. Click **Finish**. Adding a connector to a Mule project in Studio does not make that connector available to other projects in your Studio workspace. ## Configure a Source A source initiates a flow when a specified condition is met. You can configure one of these input sources to use with JMS Connector: - **JMS > On New Message** Initiates a flow by listening for incoming messages - **HTTP > Listener** Initiates a flow each time it receives a request on the configured host and port - **Scheduler** Initiates a flow when a time-based condition is met For example, to configure an **On New Message** source, follow these steps: 1. In the **Mule Palette** view, select **JMS > On New Message**. 2. Drag **On New Message** to the Studio canvas. 3. In the **On New Message** configuration screen, optionally change the value of the **Display Name** field. 4. Click the plus sign (**+**) next to the **Connector configuration** field to configure a global element that can be used by all instances of the source in the app. 5. In the **JMS Config** window, for **Connection**, select either one of the connection types to provide to this configuration: - **Active MQ Connection** - **Active MQ Connection -No Connectivity Test -** (DEPRECATED) - **Generic Connection** 6. On the **General** tab, specify the connection information for the connector, such as required libraries for the broker, JMS specification, cache strategy, authentication, and connection factory. 7. On the **TLS/SSL** tab, optionally specify a TLS configuration. 8. On the **Advanced** tab, optionally specify a reconnection strategy and XA connection pool. 9. Click **OK** to close the window. 10. In the **On New Message** configuration screen, in **Destination**, specify the name of the destination from where to consume the message. 11. Configure other optional fields in the **On New Message** configuration screen. ## Add a Connector Operation to the Flow When you add a connector operation to your flow, you immediately define a specific operation for that connector to perform. To add an operation for JMS Connector, follow these steps: 1. In the **Mule Palette** view, select **JMS Connector** and then select the desired operation. 2. Drag the operation onto the Studio canvas and to the right of the input source. The following screenshot shows the JMS Connector operations in the Mule Palette view of Anypoint Studio: ![Select any of the JMS Connector Operations from the Mule Palette view on the right side of Anypoint Studio](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-operations.png) Figure 1. JMS Connector Operations ## Configure a Global Element for the Connector To avoid connectivity issues, create separate JMS configurations for publishing and consuming, instead of creating a shared JMS configuration for both publishing and consuming. JMS Connector comes with a fine-tuned set of default values for publishing and consuming messages. The only requirement is to configure which connection to use. You can define a global default behavior for all the operations associated with the configuration and then override each parameter in only the operations that require a custom behavior. To configure the global element for JMS Connector, follow these steps: 1. Select the operation in the Studio canvas. 2. In the configuration screen for the operation, click the plus sign (**+**) next to the **Connector configuration** field to access the global element configuration fields. 3. In the **JMS Config** window, for **Connection**, select either one of the connection types to provide to this configuration: - **Active MQ Connection** - **Active MQ Connection -No Connectivity Test -** (DEPRECATED) - **Generic Connection** 4. On the **General** tab, specify the connection information for the connector, such as required libraries for the broker, JMS specification, cache strategy, authentication, and connection factory. 5. On the **TLS/SSL** tab, optionally specify a TLS configuration. 6. On the **Advanced** tab, optionally specify a reconnection strategy, and XA connection pool. 7. On the **Consumer** tab, optionally define global default behavior configurations for all the **Consume** and **On New Message** operations you have in your flow. 8. On the **Producer** tab, optionally define global default behavior configurations for all the **Publish** and **Publish consume** operations you have in your flow. 9. Click **OK** to close the window. The following screenshot shows the JMS Connector **Global Element Configuration** window in Anypoint Studio: ![JMS Connector Global Element Configuration window](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-global-configuration.png) Figure 2. JMS Connector Global Element Configuration In the XML editor, the `` configuration looks like this: ```xml ``` In the following example, you define a default **Selector** behavior when consuming a message in any of the **Consume** or **On New Message** operations associated with this configuration, while every **Publish** or **Publish consume** operation produces the outgoing message with a **Time to live** (TTL) of 60 seconds: 1. In Studio, navigate to the **Global Elements** tab. 2. Click **Create**. 3. In the filter box type `jms` and select **JMS Config**. 4. Click **OK**. 5. In the **JMS Config** window, for **Connection**, select **Active MQ Connection**. 6. In the **Consumer** tab, set the **Selector** field to ``JMSType = `INVOICE`` to filter incoming messages as invoices. ![In the Consumer tab](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-global-configuration-consumer.png) Figure 3. JMS Connector Consumer Global Configuration 5. In the **Producer** tab, set the **Time to live** field to `60000` to define the default time the message is in the broker before it expires and is discarded. ![In the Producer tab](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-global-configuration-producer.png) Figure 4. JMS Connector Producer Global Configuration In the XML editor, the ``,`selector`, and `timeToLive` configurations looks like this: ```xml ``` You can override these properties at the operation level when required. In the following example, you publish a message with a shorter TTL. To override the value of the **Time to live** field set on the global element, follow these steps: 1. In Studio, select the **Publish** operation from your flow. 2. In the **Publish** configuration screen, scroll down to the **Publish Configuration** section. 3. Set the **Time to live** field to `10000` to override the default global configuration previously set. ![In the Publish Configuration section](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-publish-configuration-1.png) Figure 5. JMS Connector Publish Configuration Override In the XML editor, the `` and `timeToLive` configurations looks like this: ```xml ``` ## Configure the Connection to a Broker To configure the connection in the global element, define the connection by selecting either **ActiveMQ Connection** or **Generic Connection** and set up the connection libraries and the JMS specification. JMS Connector also enables you to provide credentials, if you require an authenticated connection, and also to configure connection caching to increase the performance of the application. ### Configure an Active MQ Connection JMS Connector supports ActiveMQ 5 by using the **ActiveMQ Connection** setting. With this connection, you can use `JMS_1_1 (Default)` or `JMS_1_0_2b` specifications. You can also configure all the general connection parameters for JMS, as well as the custom parameters present only in ActiveMQ. After you declare the ActiveMQ connection, customize **Connection Factory** to your desired configuration. Every parameter in the connection comes with a default value, meaning that you are required to configure only the parameters relevant for your use case. Also, the ActiveMQ connection exposes parameters that are exclusive to the ActiveMQ implementation, like **Initial redelivery delay**. In the following example, you configure an **ActiveMQ Connection**: 1. In Studio, navigate to the **Global Elements** tab. 2. Click **Create**. 3. In the filter box type `jms` and select **JMS Config**. 4. Click **OK**. 5. In the **Connection** field select **ActiveMQ Connection**. 6. In the **Factory configuration** field, select **Edit Inline**. 7. Set the **Broker url** field value to the address of the broker to connect to, for example, `tcp://localhost:61616`. 8. Click **OK**. ![ActiveMQ Connection Configuration.](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-activemq-configuration.png) Figure 6. JMS Connector ActiveMQ Configuration In the XML editor, the `` and `` configuration looks like this: ```xml ``` ### Configure a Generic Connection Use **Generic Connection** to configure a connection to any broker implementation. JMS Connector provides a JNDI based (Java Naming and Directory Interface) connection factory builder that enables you to configure the connection using JNDI in the context of the application. In the following example, you configure **Generic Connection** to Artemis to use the `JMS_2_0` specification using JNDI: 1. In Studio, navigate to the **Global Elements** tab. 2. Click **Create**. 3. In the filter box, type `jms` and select **JMS Config**. 4. Click **OK**. 5. In the **Connection** field, select **Generic Connection**. 6. In the **Specification** field, select **JMS\_2\_0**. 7. In the **Connection factory** field, select **Edit inline**. 8. Set the **Connection factory jndi name** field to `ConnectionFactory`. 9. In the **Lookup destination** field, select any of the following options: - **NEVER** No lookup is done and the destinations are created using the existing JMS session. - **TRY\_ALWAYS** Tries to find the destination using JNDI, and in case it doesn’t exist, creates the destination using the current JMS session. - **ALWAYS** If a queue or topic cannot be found via JNDI, the lookup fails with a `JMS:DESTINATION_NOT_FOUND` error. 10. Select the **Name resolver builder** field. 11. Set the **Jndi initial context factory** field to `org.apache.activemq.artemis.ActiveMQInitialContextFactory`. 12. Set the **Jndi provider url** field to `tcp://localhost:61616?broker.persistent=false&broker.useJmx=false`. 13. Set **Provider properties** to **Edit inline**. 14. Click the plus sign (**+**) to add a new provider property. 15. In the **Provider property** window, set the **Key** field to `queue.jndi-queue-in` and the **Value** field to `in.queue`. 16. Click **Finish**. 17. Repeat Step 14. 18. Set the **Key** field to `topic.jndi-topic-in` and the **Value** field to `in.topic`. 19. Click **OK**. ![Generic Connection Configuration.](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-generic-configuration.png) Figure 7. JMS Connector Generic Configuration In the XML editor, the `` and `` configuration looks like this: ```xml ``` ### Configure the Connection Libraries When you configure any connection type, you must always configure a library containing the JMS client implementation, because JMS Connector is not bound to any particular implementation. You can configure ActiveMQ external libraries and generic external libraries found in the global elements view of Studio, you can manually add the library dependency in your `pom.xml` file. #### ActiveMQ External Libraries For an **ActiveMQ Connection**, you can configure three libraries: - **ActiveMQ KahaDB** The `activemq-kahadb-store` dependency is required only when using an persistent in-memory broker based on the VM transport (such as `vm://localhost?broker.persistent=true`). This dependency provides a valid `org.apache.activemq.store.kahadb.KahaDBPersistenceAdapter` implementation. In your `pom.xml` file in Studio, adding the dependency looks like this: ```xml org.apache.activemq activemq-kahadb-store 5.14.4 ``` - **ActiveMQ Broker** The `activemq-broker` dependency is required only when using an in-memory broker based on the VM transport (which is the one configured by default). This dependency provides a valid `org.apache.activemq.broker.Broker` implementation. In your `pom.xml` file in Studio, adding the dependency looks like this: ```xml org.apache.activemq activemq-broker 5.14.4 ``` - **ActiveMQ Client** The `activemq-client` dependency is always required. Choose one that provides a valid `org.apache.activemq.ActiveMQConnectionFactory` implementation. In your `pom.xml` file in Studio, adding the dependency looks like this: - ```xml org.apache.activemq activemq-client 5.14.4 ``` To configure these libraries in the Global Element view, follow these steps: 1. In Studio, navigate to the **Global Elements** tab. 2. Click **Create**. 3. In the filter box, type `jms` and select **JMS Config**. 4. Click **OK**. 5. In the **Connection** field, select **ActiveMQ Connection**. 6. In the **Required Libraries** section that shows the **ActiveMQ KahaDB**, **ActiveMQ Broker** and **ActiveMQ Client** libraries, click the **Configure…​** button to install the dependency. 7. Select any of the following install options: - **Add recommended library** Installs the recommended library. - **Use local file** Browse to a local file for the required engine library and install it. - **Add Maven dependency** Browse to the dependency and install it. #### Generic External Libraries For **Generic Connection**, provide all the libraries that the connection factory of your implementation requires. Ensure that you supply all the required dependencies to the application. In the following example, you configure a generic library for a connection that uses a JMS 2.0 specification, which requires a generic connection with a different client library, like Apache Artemis: In your `pom.xml` file in Studio, adding the dependency looks like this: ```xml org.apache.activemq artemis-jms-client-all 2.17.0 ``` To configure these libraries in the Global Element view, follow these steps: 1. In Studio, navigate to the **Global Elements** tab. 2. Click **Create**. 3. In the filter box, type `jms` and select **JMS Config**. 4. Click **OK**. 5. In the **Connection** field, select **Generic Connection**. 6. In the **Required Libraries** section that shows the **JMS Client**, click the **Configure…​** button to install the dependency. 7. Select any of the following install options: - **Add recommended library** Installs the recommended library. - **Use local file** Browse to a local file for the required engine library and install it. - **Add Maven dependency** Browse to the dependency and install it. ### Configure the JMS Specification The JMS **Specification** you configure must be supported by the broker implementation associated with the connection; otherwise, the connection fails. Note that features that are available only in `JMS_2_0` won’t work with any other specification. To configure the JMS specification in Studio, follow these steps: 1. In Studio, open the **JMS Config** global element window. 2. In the **Specification** field, select one of the following supported specifications: - **JMS\_1\_1 (Default)** - **JMS\_1\_0\_2b** - **JMS\_2\_0** 3. Click **OK**. ![In the Specification field select one of the supported specifications](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-spec-config.png) Figure 8. JMS Connector specification configuration In the XML editor, the `specification` configuration looks like this: ```xml ``` ### Configure Connection Caching To connect with a broker and execute required operations, JMS Connector creates multiple sessions of consumers and producers that can be cached and reused to increase application performance. JMS Connector enables you to configure the **Caching strategy** field to use when creating new connections. By default, both consumers and producers are cached and as many concurrent instances are cached in memory. Do not disable the sessions cache by using the **No caching** configuration, which is used only with a custom connection factory that already manages its own cache. In the following example you configure the caching strategy: 1. In Studio, open the **JMS Config** global element window. 2. In the **Caching strategy** field, select **Default caching (Default)**. 3. Set the **Session cache size** field to `100`. 4. Select **Cache producers**. 5. Click **OK**. ![In the Caching strategy field select the desired caching strategy](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-caching-config.png) Figure 9. JMS Connector caching strategy configuration In the XML editor, the `` and `` configuration looks like this: ```xml ``` In the following XML example, the `` configuration looks like this: ```xml ``` ### Configure the Client Identifier and Credentials for Authentication The client identifier associates a connection and its objects with a state that is maintained on behalf of the client by a provider. It is mandatory for identifying an unshared durable subscription. Note that the client state identified in the **Client id** can be used by only one connection at a time. In the following example, you configure an authenticated connection and the client identifier: 1. In Studio, open the **JMS Config** global element window. 2. In the **Connection** section, set the **Username** field to `${env.user}` and the **Password** field to `${env.pass}`. 3. Set the **Client id** field to `${env.clientId}`. 4. Click **OK**. ![In the Connection section, set the Username, Password, and Client id fields.](/mulesoft/current/en-us/jms-connector/1.10/_images/jms-authentication-config.png) Figure 10. JMS Connector authenticated connection and client identifier configuration In the XML editor, the `username`, `password`, and `clientId` configuration looks like this: ```xml ``` ## View the App Log To check for problems, you can view the app log as follows: - If you’re running the app from Anypoint Platform, the output is visible in the Anypoint Studio console window. - If you’re running the app using Mule from the command line, the app log is visible in your OS console. Unless the log file path is customized in the app’s log file (`log4j2.xml`), you can also view the app log in the default location `MULE_HOME/logs/.log`. ## See Also - [Introduction to Anypoint Connectors](https://docs.mulesoft.com/connectors/introduction/introduction-to-anypoint-connectors) - [Using Anypoint Studio to Configure a Connector](https://docs.mulesoft.com/connectors/introduction/intro-config-use-studio) - [JMS Connector Reference](https://docs.mulesoft.com/jms-connector/1.10/jms-connector-reference) - [Salesforce Help](https://help.salesforce.com)
