Qpid JMS event receiver is an internal event receiver that comes with WSO2 products by default. You can configure it with map, XML, JSON, and text input mapping types.
Prerequisites
Follow the steps below to set up the prerequisites before starting the event receiver configurations.
Install JMS-Qpid Broker and JMS-Qpid Client.
- Add the following broker-specific JAR files to
<PRODUCT_HOME>/repository/components/lib/directory.
< ACTIVEMQ_HOME>/lib/geronimo-jms_1.1_spec-1.0.jar<QPID-CLIENT_HOME>/lib/ qpid-client-xxx.jar<QPID-CLIENT_HOME>/lib/ qpid-common-xxx.jar
- Start the Qpid JMS server.
Creating a Qpid JMS event receiver
For instructions on creating a Qpid JMS event receiver, see Configuring Event Receivers.
Configuring adapter properties
Specify the Adapter Properties, when creating a Qpid JMS event receiver using the management console as shown below.
After entering the above adapter properties, select the Event Stream to which you want to map the incoming events, and the Message Format which you want to apply on the receiving events. Also, click Advanced to define custom input mappings based on the Message Format you selected. For more information on custom input mapping types, see Input Mapping Types.
You can also d efine the respective adapter properties of the event receiver based on the transport type within the <from> element of the event receiver configuration in the <PRODUCT_HOME>/repository/deployment/server/eventreceivers/ directory as follows.
