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.
You lost me here.
there is two ways to go
1) you can implement the project manager to create Jobs and monitor the
progress based on estimated. Once the Job goes out of spec the project
manager can show the best way to make a decision on how to get back on
track and create the jobs to do that.
This is part of ERP where Positions are created for HR, through the Work
effort.
Since we have the frame work for production runs this would take less
design and integration time in my opinion.
2)when Jobs are created they create a Project that can be tracked as in #1.
as a matter of fact that was my goal years ago, on integrating an GNATT project
into ofbiz. Problem was it used SWT.

hi Scott,
I don't know much about Quartz. But I really think it is the correct
direction to migrate home-grown codes to mature third party solution or
separate mature ofbiz components as standalone framework. As such, we can
focus on value creation and furthermore it might help attract more
developers to join.

Hi All,
I was looking at the Quartz Scheduler project (www.quartz-scheduler.org)
over the weekend and it looks like it could be a good fit for OFBiz. We ran
into some issues with the scheduled service code in OFBiz recently where a
heavy server load would cause all sorts of strangeness (multiple reschedules
for a single failed job, inability to purge old jobs before a timeout, those
two combined eventually bringing the server to its knees), and my options
are to either find and fix the problem(s) or replace the scheduler with an
external solution.
I've only had a brief look but it appears like quartz is pretty extensible
and would allow us to continue to support things like temporal expressions
(and the deprecated recurrence infos) and could probably increase the number
of scheduling features available to OFBiz. It's ASL2 licensed and seems to
be pretty mature.
Does anyone have any experience with quartz to share? Opinions or other
possible alternatives would be most welcome. I'm not looking to implement
anything anytime soon but figured we may as well start discussing it.
Thanks
Scott
