Contributing back to the jBPM community - business calendar

[stevenl]

Hi All,

Firstly, great product guys. jBPM has met our expectations with what we were requiring regarding an open source BPM solution.

For a project I?ve been involved with, I?ve had to implement jBPM v3.1.2 to cater for number of business requirements. Two requirements that carry the most importance for this thread are outlined below:
1. a requirement where the business time duration between two dates had to be calculated
2. business calendar properties file to be loaded from a location that is easy to maintain (in this case, the server file system)

I have had to modify core jBPM code as I was unsuccessful in finding functionality in jBPM that could handle the two requirements outlined above.

So I wish to present a question regarding code that I wish to contribute back to the jBPM community ? I believe this is mandatory as per the LGPL licence agreement. In this case, two new classes: one that contains a method that will calculate the business time duration between two dates and another class that will accept a valid calendar properties file to configure the jBPM calendar feature. What is the best approach to doing this?

I have searched the jBPM JIRA and have found two applicable issues relating to the two points made above.

http://jira.jboss.com/jira/browse/JBPM-99
Point 2 in issue JBPM-99 highlights the exact functionality that I required (for point 1 - above), however I wasn?t able to find the implementation in jBPM.

http://jira.jboss.com/jira/browse/JBPM-927
The resolution for issue JBPM-927 has resolved my second point in a more recent version of jBPM.


Any pointers in the right direction would be greatly appreciated.

Kind regards,
Steven Looi

good research. all your points are correct afaict.

we don't have diff calculation between two business dates. because for process language purposes, we only need addition.

if it's easy for us to incorporate your business time diff functionality, we're interested if there is at least 1 unit test case that shows the feature.

you'll have to sign the contributors agreement in order to contribute it directly.

Thanks for the prompt reply Tom.

I have a number of unit tests that test the business time duration functionality. The unit test class as well as the new BusinessTime class (that contains the methods used to calculate the business time duration) are ready for review/ contribution.

I will email you to obtain further instructions.

Regards,
Steven

Can anybody provide sample solution how to implement diff calculation between two business dates?

Guys, any reply? Need urgent!!!

A reply... but probably not the one you want :-)

First of all, this is a forum for discussing functionality of jBPM for people working ON jBPM, not with jBPM. Secondly, It is not a forum to request solutions. Thirdly, if it is urgent, buy commercial support (but I think only consultancy will help) or hire a java developer, 4th, there was a weekend in between... people do take a rest sometimes. 5th, you 'abuse' a 1.5 year old post.
