Configuring Java Message Service (JMS) The Java Message Service (JMS) is a Java API that KIE Server uses to exchange messages with other application servers such as Oracle WebLogic Server and IBM WebSphere Application Server. You must configure your application server to send and receive JMS messages through KIE Server to ensure collaboration between the two servers. 45.2.1. Create a service bus and add IBM WebSphere Application Server You must create a service bus and add the IBM WebSphere Application Server as a member in order to use JMS. Procedure In the WebSphere Integrated Solutions Console, navigate to Service Integration Buses New . Enter a new bus name and clear the Bus Security option. Click and then Finish to create the service bus. Select the service bus that you created. Under Topology , select Bus Members Add . In the Add a New Bus Member wizard, choose the IBM WebSphere Application Server and the type of message store for persistence. You can also specify the properties of the message store. Click Finish to add the new bus member. 45.2.2. Create JMS connection factories To enable messaging with KIE Server, you must create certain JMS connection factories for sending and receiving messages. Prerequisites You have created a service bus for IBM WebSphere Application Server. Procedure In the WebSphere Integrated Solutions Console, navigate to Resources JMS Connection Factories . Select the correct scope and click New . Select the Default Messaging Provider option and click OK . For each of the following required connection factories, enter the name of the connection factory (for example, KIE.SERVER.REQUEST ) and the JNDI name (for example, jms/cf/KIE.SERVER.REQUEST ), and then select the service bus from the Bus Name drop-down list. Leave the default values for the remaining options. Click Apply and then click Save to save the changes to the primary configuration, and repeat for each required factory. 45.2.2.1.

Create JMS queues JMS queues are the destination end points for point-to-point messaging. You must create certain JMS queues to enable JMS messaging with KIE Server. Prerequisites You have created a service bus for IBM WebSphere Application Server. Procedure In the WebSphere Integrated Solutions Console, navigate to Resources JMS Queues . Select the correct scope and click New . Select the Default Messaging Provider option and click OK . For each of the following required queues, enter the name of the queue (for example, KIE.SERVER.REQUEST ) and the JNDI name (for example, jms/KIE.SERVER.REQUEST ), and then select the service bus from the Bus Name drop-down list. From the Queue Name drop-down list, select the Create Service Integration Bus Destination , enter a unique identifier, and select the bus member that you created previously. Click Apply and then click Save to save the changes to the primary configuration, and repeat for each required queue. 45.2.3.1. JMS queues for KIE Server The following table lists the required Java Message Service (JMS) queues that enable JMS messaging with KIE Server: Table 45.2. Required JMS queues for KIE Server Name Default value Used for KIE.SERVER.REQUEST jms/KIE.SERVER.REQUEST Sending all requests to KIE Server KIE.SERVER.RESPONSE jms/KIE.SERVER.RESPONSE Receiving all responses produced by KIE Server 45.2.4. Create JMS activation specifications A JMS activation specification is required in order to bridge the queue and the message-driven bean that enables JMS. Prerequisites You have created a service bus for IBM WebSphere Application Server. You have created JMS queues. Procedure In the WebSphere Integrated Solutions Console, navigate to Resources JMS Activation Specifications . Select the correct scope and click New . Select the Default Messaging Provider option and click OK . For each of the following required activation specifications, enter the name of the activation specification (for example, KIE.SERVER.REQUEST ) and the JNDI name (for example, jms/activation/KIE.SERVER.REQUEST ), and then select the service bus from the Bus Name drop-down list. From the Destination Type drop-down list, select Queue and enter the name of the corresponding queue as a Destination lookup (for example, jms/KIE.SERVER.REQUEST ). Click Apply and then click Save to save the changes to the primary configuration, and repeat for each required activation specification. 45.2.4.1. JMS activation specifications for KIE Server The following table lists the required Java Message Service (JMS) activation specifications that enable JMS messaging with KIE Server: Table 45.3. Required JMS activation specifications for KIE Server Name Default value Used for KIE.SERVER.REQUEST jms/activation/KIE.SERVER.REQUEST Sending all requests to KIE Server KIE.SERVER.RESPONSE jms/activation/KIE.SERVER.RESPONSE Receiving all responses produced by KIE Server 45.3. Setting system properties in IBM WebSphere Application Server Set the system properties listed in this section on your IBM WebSphere Application Server before you deploy KIE Server. Procedure In the WebSphere Integrated Solutions Console, navigate to Servers Server Types IBM WebSphere Application Servers .
