Comment lines: Software solution resiliency guidelines can help prevent bad behavior
Unit testing, system functional testing, performance testing, and the like have traditionally been the only kind of testing that is performed in some form or fashion when implementing a new or updated system. Unfortunately, often overlooked is resiliency testing. The result is that when resiliency issues surface, operations, administration, network, systems, and database personnel all scramble to find the root cause. This typically leads to a relatively lengthy project to ensure the solution becomes - and stays - resilient. This article offers guidelines you can follow to ensure the IT solution is more resilient to environmental changes.

However, text editors do not provide language-specific support for Jython. PyDev is a plugin for Eclipse that is specifically tailored to Python and Jython program development. PyDev has the usual language-specific features you expect in an integrated development environment (IDE) to enhance your Jython scripting productivity. The PyDev plugin needs some special configuration to support the specifics of wsadmin scripting. This article describes how to configure the PyDev plugin for Eclipse specifically for Jython and wsadmin scripting. The PyDev capabilities will improve your wsadmin scripting productivity by cutting down on errors, such as improper indenting, incorrect syntax, and undefined variable usage.

Comment lines: Using an adapter service pattern to build a more flexible, low maintenance ESB
Integrating multiple systems in a point to point manner can be very time consuming and expensive to maintain. One common approach to resolve this issue is to introduce an Enterprise Service Bus (ESB), which replaces the point to point approach with a single, centralized place to integrate systems, and does so in a service-oriented manner. However, if done incorrectly, this can still create maintenance headaches. Here is a look at a pattern that can “future proof” your integration work, allowing for the upgrading or replacement of legacy systems without excessive additional integration work.
