External clients
The server can send messages to, or receive messages from, external clients using JMS bindings.
An external client (such as a web portal or an enterprise information system) can send a message to an SCA module in the server, or it can be invoked by a component from within the server.
The JMS export components deploy message listeners to listen to requests incoming to the receive destination specified in the export binding. The destination specified in the send field is used to send the reply to the inbound request if the invoked application provides a reply. Thus, an external client is able to invoke applications with the export binding.
JMS imports interact with external clients by sending messages to, and receiving messages from, JMS queues.
- Work with external clients
An external client (that is, outside the server) might need to interact with an application installed in the server.
