Personally, I would avoid adding columns to the existing tables themselves,
again this rule DOES not apply to all, but if anything were to change within
jbpm you could be potentially impacted. Which could be a fairly big problem for
some.
So coupling one's own data with jbpm is a little riskier
would it be possible to share your custom handler class. I am aware of updating
the hbm.xml file but not sure whether of the handler class.

Yes that works (one of the advantages of open source), but is scary to a lot of
people. Upgrading etc...
You can also create additional columns in the existing jbpm tables ..so
whenever a process and task is updated it will fill these columns with the meta
data you want. You might need to declare this columns in your hibernate config
and write a custom handler class..I have done this and it works b
Yes I meant after deployer returns without an error, update custom created
table.
Also if you have a look at the ProcessDefinitionQuery there is no way one can
use to query such meta information.

'all' ? 40? 6000? to query it every now and then... Still way easier than
adding a table to jBPM, changing the deployer etc... or was that not what you
meant?
If you meant creating your own table fully outside jBPM and when the deployer
returns without an error you update your table, then I ag
Thanks again. I feel this wont be performant.
take for example if i wanted to know how many processes are delpoyed by a user

Why wont that be helpful? Maybe the usage of 'occasionally' confused you. It
did me when I re-read it. I meant to say that if you don't need to query based
on these attributes you can just put it in the xml. If you do need to query on
them, you can always when starting a task or process, read it
Thanks for the information. so putting in the xml file wont be helpful.
Is there any other way ?

If you only need it occasionally, you can always just add it to the xml of the
definition and read that xml file when needed and get the specific
attribute/element. No need to adapt the database for this.
