Developing a WebLogic JMS Application

Application Development Flow

Importing Required Packages

Setting Up a JMS Application

Step 1: Look Up a Connection Factory in JNDI

Step 2: Create a Connection Using the Connection Factory

Step 3: Create a Session Using the Connection

Step 4: Look Up a Destination (Queue or Topic)

Step 5: Create Message Producers and Message Consumers Using the Session and Destinations

Step 6a: Create the Message Object (Message Producers)

Step 6b: Optionally Register an Asynchronous Message Listener (Message Consumers)

Step 7: Start the Connection

Example: Setting Up a PTP Application

Example: Setting Up a Pub/Sub Application

Sending Messages

Step 1: Create a Message Object

Step 2: Define a Message

Step 3: Send the Message to a Destination

Dynamically Configuring Message Producer Configuration Attributes

Example: Sending Messages Within a PTP Application

Example: Sending Messages Within a Pub/Sub Application

Defining Server Session Pools

Step 1: Look Up Server Session Pool Factory in JNDI

Step 2: Create a Server Session Pool Using the Server Session Pool Factory

Step 3: Create a Connection Consumer

Example: Setting Up a PTP Client Server Session Pool

Example: Setting Up a Pub/Sub Client Server Session Pool

Using Multicasting

Step 1: Set Up the JMS Application, Creating Multicast Session and Topic Subscriber

Step 2: Set Up the Message Listener

Dynamically Configuring Multicasting Configuration Attributes

Example: Multicast TTL

 

Using Transactions with WebLogic JMS

Overview of Transactions

Using JMS Transacted Sessions

Step 1: Set Up JMS Application, Creating Transacted Session

Step 2: Perform Desired Operations

Step 3: Commit or Roll Back the JMS Transacted Session

Using JTA User Transactions

Step 1: Set Up JMS Application, Creating Non-Transacted Session

Step 2: Look Up User Transaction in JNDI

Step 3: Start the JTA User Transaction

Step 4: Perform Desired Operations

Step 5: Commit or Roll Back the JTA User Transaction

Asynchronous Messaging Within JTA User Transactions Using Message Driven Beans

Example: JMS and EJB in a JTA User Transaction
