AJAX and JMX are at opposite ends of the Systems Management stack. However, the emerging ubiquity of the AJAX model for rich browser clients has obscured the benefits the model provides in the architectural space for enhancing support patterns within the problem resolution pipeline. This article elaborates on an architectural benefit of AJAX that lets the management state be 'broadcast' to a browser-enabled user base without waiting for a page refresh. This architecture is an extension of a general pattern for logging JMX events and properties to a server-side log file; this variation logs or 'broadcasts' management information to the (AJAX-enabled) user base. Emphasis is placed on the AJAX request/response model and the painting of management data to the page, together with the beautiful JMX notification framework, all neatly integrated in the middle with an instrum...

Prototyping an Advanced Calendar Class Using JavaScript

It is possible to create a very attractive look-and-feel prototype of a Calendar-based browser application in JavaScript, but to compete with tough-minded mainframe legacy systems such as MEMO requires a highly functional and scalable working prototype to justify the continued investment and potential encapsulation of a large mainframe system. After it was suggested that an existing MEMO-based system was to be superceded, an opportunity arose to port some of the legacy application functionality to the new Intranet and browser medium, hopefully gaining a more attractive interface...

Enterprise Strategy with Java

Increasingly, technologists are asked by strategists to state the capability of Java within a distributed component architecture. The larger corporate platform is mixed and the owning, interacting businesses must implement a framework technical architecture in which present and future components can co-exist and change with minimum impact. Larger installations contain data and applications at corporate and departmental levels across a heterogenous computing environment. Technologists, thus, have to articulate some of the values and norms of the business strategist as the business... (more)
