Establishing a connection between the browser and server-side events (web messaging)
The web messaging service is a publish/subscribe implementation, which connects the browser to the WebSphere® Application Server service Integration Bus for server-side event push to the browser.
About this task
You must carefully plan prior to developing and installing
a web messaging enabled application. Some items that you must plan
for:
- Understand the impacts of using long-lived connections from a client to a server. Your infrastructure must support the challenges of running a web messaging enabled application.
- Determine how a browser or client connects to the web messaging service.
- The web messaging service bridges clients to the service Integration Bus for publish/subscribe operations. A service Integration Bus must be created and configured. This task requires planning.
- How messages are sent to your web messaging clients.
- Determine key metrics, such as number of concurrent clients, number of client subscriptions, publish rate. Configure a workload managed application infrastructure if a single server cannot handle scale to meet your needs.
- There are special considerations when you enable security for a web messaging enabled application.
- Understand the concerns when you deploy an application into a cluster.
- Understand what is involved in enabling an application to use the web messaging service.
