Building custom components for Adobe LiveCycle ES can be as simple as writing an xml file. In fact, that’s all I had to do to convert a couple of POJOs into a ShortenURL & Twitter custom components. However things can always be made easier which is what this new Adobe Labs project aims to do.
Adobe® LiveCycle® Workbench ES Component Development Tool is a Plug-in for Eclipse that helps Java developers build a custom Component for LiveCycle ES. The Component Development Tool makes is easy to create a new Java project used to build a Component jar file, define the Services and Operations your Component will expose and include third party Java logic inside your Component. The Component Development Tool includes a GUI to help create and modify your component XML.
