Your ability to modify the source code is not diminished, if you really want to you just download the quartz open source and recompile it with your mods. > One of the reasons I don't like Opentaps is I have to learn all these outside > systems besides what is in ofbiz. That is an example of technology bloat, which is different from what I'm suggesting here. OFBiz is going to have a job manager whether it is our code or someone else's doesn't reduce the need to learn it. Quartz does however offer better documentation and learning it has a good chance of being useful for non-OFBiz projects. > Seems to me we have a project manager that would fit into this.
