This article shows how to develop a simple plugin which provides a custom transformation step for Kettle 4.0. The transformation step should accept any row stream and append a string field at the end, filling it with a fixed value. The user should be able to define the name of the added field. For starters, that should be enough. Keeping the step functionality at a minimum allows me to explain how the plugin interfaces with Kettle with as little distraction as possible.
"The RHQ project is a systems management suite that provides extensible and integrated systems management for multiple products and platforms across a set of core features such as
monitoring and graphing of values
alerting on error conditions
remote configuration of managed resources
remote operation execution
The project is designed with layered modules that provide a flexible architecture for deployment. It delivers a core user interface that provides audited and historical management across an entire enterprise.
A Server/Agent architecture provides remote management and plugins implement all specific support for managed products.
RHQ is an open source project licensed under the GPL, with some pieces individually licensed under a dual GPL/LGPL license to facilitate the integration with extended packages such as Jopr (now included in RHQ) and Embedded Jopr."

"Developers usually have their programs write log and debug information to the standard output during coding and testing. This results in a lot of text being printed to Eclipse's console view, often more than can be easily surveyed. Since at any given time, only a small part of this information is of primary interest to the developer, a tool which highlights specific lines or words can significantly increase the readability of this output.
Grep Console allows you to define a series of regular expressions which will be tested against the console output. Each expression matching a line will affect the style of either the entire line or parts of it. For example, error messages could be set to show up with a red background, or integer values showing the state of a certain variable could be rendered in bold font. "
The NumberFormatException is thrown when we try to convert a string into a numeric value such as float or integer, but the format of the input string is not appropriate or illegal.
