Pushing Data to Multiple WebSocket Clients From a Java Server Finished writing the WebSocket chapter for the second edition of my Java 24 Hour Trainer. In this blog I’ll show you one of the code samples from lesson 28. Pretty often you need to write a program that publishes the same message to all connected clients. For example, multiple clients of the online auctions have to be notified when a new bid is placed on the product. Another example is when a new stock price quote need to be pushed from the server to all connected clients. With websockets it’s a pretty easy task. I’ll show you a basic example when a WebSocket endpoint pushes the server’s time to all connected clients. If you can publish the server’s time to all connected clients, you can publish any application-specific data. The following endpoint WebSocketClock schedules the task that gets and formats t...

Demystifying the Art of Integrating Enterprise Applications

Enterprise Architecture Integration (EAI) is the process of integrating enterprise software that enables reuse of existing applications and allows for quick integration of best-of-breed, custom off-the-shelf (COTS) products. This article will attempt to demystify the art of integrating enterprise applications and to supply an approach that can be used to quickly link disparate systems. EAI Primer In today's IT environment, it is rare to work on a project that does not require integration with a COTS product or legacy system. Corporations are often unable to commit the vast sums ...

Service on Demand Portals

Enterprises are moving towards a highly collaborative environment to achieve higher competitive advantage. Availability of the right information across the enterprise at the right time has become a key capability to provide such an advantage. Though this was a well-understood objective, various architectures that evolved to manifest such an enterprise information delivery infrastructure were not elegant, intuitive, or aligned to governance and organizational dynamics. With the emergence of service-oriented architecture (SOA) and Web Service for Remote Portals (WSRP), the enterpr... (more)

Towards Legacy Enablement Using SOA and Web Services

Legacy systems are a core asset at many organizations. These legacy systems have been around for decades and have a very critical impact on day to day business processes. However, owing to a variety of reasons, these legacy systems have high TCO and represent a bottleneck towards the emergence of an agile IT portfolio. In this article we'll focus on a variety of options that may be available for the seamless integration of legacy systems with an enterprise IT portfolio. We converge on legacy enablement using Web services as a viable option towards achieving an integrated, agile a... (more)
