This is a partially working project, at present it is able to serve out formatted IDs. My next task is to make it aware of different users/groups/databases that can have different ids/formats/etc. This may take a while but since I have a working project I may be more motivated to continue improving its current state.
As another thought, this is something that should be have multiple interfaces. I can think of two at the moment, as a service, and by directly using the JSP.
20071105 TM: This could probably be put into a story so it's easier to track changes. As a refinement to the comments this should be configurable, what I mean, for example, is that there should be minimum and maximum values, a format (i.e. hex or decimal), caching or not, and if so the number to cache.
