Of late, we've been making more of a push on the Eclipse Tooling for Smooks within JBoss Tools. Prior to a few weeks ago, Dart Peng was “more or less” left to his own devices on this work, without much help from myself or anyone else. More recently, Brian Fitzpatrick and I have been more actively contributing to the great work being done by Dart.
Brian has been blogging about this work here on the JBoss Tools blog. Please take a look and contribute your throughs and ideas!!!
In time, this work will feed back into the ESB Configuration Editor, making it a lot easier to perform transformations (and other data manipulation processes) on the ESB.
