This document describes webSpoon, a web-based version of Spoon that allows users to access and edit Kettle transformation files from a web browser. WebSpoon uses RAP/RWT, which provides web UIs with the same APIs as SWT, allowing Spoon to run as a web application with minor code changes. This allows users to access Spoon from smartphones/tablets, avoids sensitive data storage issues, and provides seamless experience between business analysts and developers. Screenshots show webSpoon's graphical programming interface and repository access. The document also discusses webSpoon as a plugin for business applications like CDE and App Builder.

What is webSpoon?
2
• This is a web-based Spoon.
• Spoon relies on SWT for UI widgets: SWT is great for making it OS
agnostic, but it locks it as a desktop app.
• RAP/RWT (one of Eclipse projects) provides web UIs with SWT API, so
replacing SWT with RAP/RWT allows Spoon to run as a web app with a
little code change.

SWT and RWT

API as SWT.
• With RAP/RWT, most of the codebase can be reused.
