How to configure JMS on Weblogic Server 12c
JMS Server:
A JMS server acts as a management container for resources which
are available in JMS modules. Some of
its responsibilities include the maintenance of persistence and state of messages and
subscribers. A JMS server is required in
order to create a JMS module.
JMS Module:
A JMS module contains JMS resources such as queues/topics. A
JMS module is required in order to create a JMS queue.
Subdeployment:
JMS modules are targeted to one or more WLS instances or a
cluster. Resources within a JMS module,
such as queues and topics are also targeted to a JMS server or WLS server
instances. A subdeployment is a grouping of targets. It is also known as
advanced targeting.
Connection Factory:
A connection factory is a resource that enables JMS clients
to create connections to JMS destinations.
JMS Queue:
A JMS queue (as opposed to a JMS topic) is a point-to-point destination
type. A message is written to a specific queue or received from a specific
queue.
The objects used in this example are:
Object Name

Type

JNDI Name

DemoJMSModule

--------------------------------------------------
1. JMS Server Configuration Steps:
1.1. Create a JMS Server: Services > Messaging > JMS Servers
1.2. Select New
1.3 Name: DemoJMSServer
Persistent Store: (Click on Create a New Store )-
Select Type ="JDBC Store" and click next
Provide below details -
Click next and finish. then select the newly created JDBC Store and click next -
1.4. Target: soa_server1 (or choose an available server)
1.5. Finish - Click Finish.
The JMS server should now be visible in the list with Health OK.
--------------------------------------------
2. JMS Module Configuration Steps :
2.1. Services > Messaging > JMS Modules
2.2. Select New
2.3. Name: DemoJMSModule and Leave the other options to default
2.4. Targets: soa_server1 (or choose the same one as the JMS server)
PressNext
2.5. Leave “Would you like to add resources to this JMS system
module” unchecked and pressFinish.
DemoJMSModule is created successfully.
--------------------------------------------------
3. Create a SubDeployment :
A subdeployment is not necessary for the JMS queue to work, but it allows you to easily target subcomponents of the JMS module to a single target or group of targets. We will use the subdeployment in this example to target the following connection factory and JMS queue to the JMS server we created earlier.
3.1. Services > Messaging > JMS Modules
3.2. Select DemoJMSModule
3.3. Click on Subdeployments tab and New
3.4. Subdeployment Name: DemoSubdeployment
3.5. Press Next
3.6. Select Target - Here you can select the target(s) for the subdeployment. You can choose either Servers (i.e. WebLogic managed servers, such as the soa_server1) or JMS Servers such as the JMS Server created earlier.
As the purpose of our subdeployment in this example is to target a specific JMS server, we will choose the JMS Server option.
Select the DemoJMSServer created earlier
3.7. Press Finish
--------------------------------------
4. Create a Connection Factory
4.1. Services > Messaging > JMS Modules
4.2. Click on DemoJMSModule and press New
4.3. Select Connection Factory and Next
4.4. Name: DemoConnectionFactory
JNDI Name: jms/DemoConnectionFactory
Leave the other values at default
4.5. On the Targets page, select the Advanced Targeting button and select DemoSubdeployment
4.6. Press Finish
The connection factory should be listed on the following page with DemoSubdeployment and DemoJMSServer as the target.
----------------------------------------------
5 Create a JMS Queue
5.1. Services > Messaging > JMS Modules
5.2. Click on DemoJMSModule and press New
5.3. Select Queue and Next
5.4. Name: DemoJMSQueue
JNDI Name: jms/DemoJMSQueue
Template:None
PressNext
5.5. Subdeployments: DemoSubdeployment
5.6. Finish
The DemoJMSQueue should be listed on the following page with DemoSubdeployment and DemoJMSServer.
Release Configuration.
The JMS queue is now complete and can be accessed using the JNDI names
jms/DemoConnectionFactory
jms/DemoJMSQueue.
Keep Learning ! Cheers Guys!!
