Hi
Instead of using a workaround, did you have a look to rule templates ?

Yes, there is me !
I even have a fresh newly updated french file (for 5.3.0.Final version), as the

I was thinking of updating the former JIRA with the new file ?
The then part is java. Your question can thus be reformulated as
preventing java code for doing dangerous operations.
One of basic solution is to run your java code (containing drools or
not) under a specific user (not root) that only have rights for some
specific folders.
As I think you
The last time (Nov.2011) I tried to use drools 5.3.Final with java 7

With Guvnor, you can also use working set (see here ) to restrict the
availiable fields to expose to a business user, by selecting class and/or
fields of an existing class, and even more (businnes contraints on values, with
rules).
The only problem I see with working sets, is that you must
It happends as soon as your project is set as a Drools project.
What you can is cutting your project in 2 sub-projects :
- One for rules, tagged as a Drools project,
- Another pure java project, containing eventually some normal XLS,
which is used as a dependancy for your drools project
Have a look there too :
http://drools.46999.n3.nabble.com/quot-Rule-Id-quot-for-a-Drools-Rule-td2914385.html
or use a WorkingMemoryEventListener and a AgendaEventListener together
to set the name for all freshly inserted objects.

First solution is the one I use almost all times, and moving facts from a

The second solution could be great too, but I am not sure that it will cut all

I have two simple classes : The parent class has a field that is an enum. The

In my opinion, for 300 drl files, the better is to use a specific KB for

This way you don't have to pollute your rules with control facts (and
you can eventually re-use some part of DRL files into multiple context
