Record marked as obsolete and not updated for a long time.
Apple WebObjects was a web application server and web application framework written in Java. The software was used to develop and run web applications.
A woo file contains various data used for internal purposes by WebObjects. Its contents are associated with the surrounding WebObjects application and should not normally be treated as a standalone document.
WebObjects was available for Mac OS X and macOS. The format is obsolete: the last stable release of WebObjects was in 2008, and Apple stopped releasing new versions.
A woo file is intended to be used by the corresponding WebObjects application rather than opened directly. On Mac OS X or macOS, open the associated WebObjects project or application in a compatible installation of WebObjects.
Because WebObjects is obsolete, a current macOS system may not be able to open the file. If the file belongs to an older application, it may require the original WebObjects environment.
There is no general-purpose conversion for a woo file. The file contains internal WebObjects data, so it cannot normally be converted independently to a common document format.
If the data is needed in another format, it must generally be exported by the associated WebObjects application or recovered from the WebObjects project in which the file was used.
