Marina,
My first advise for you is to forget JSR94. It is not worth to use it.
Regarding the creation of rules via API, you can use the descriptor
classes in the package: org.drools.lang.descr.
There is not much documentation (anyone up to help on that?) but it is
easy to understand how it works... just look at the result of parsing a DRL
file and you will easily figure out:
DrlParser parser = new DrlParser();
PackageDescr pkgDescr = parser.parse( source );

Hello,
I am working on a project that requires a rules engine to handle numerous
rules for approval chain determination. My main choice at the moment is
JBoss Rules engine. One issue came up though that I could not find a good
answer in the documentation:
Is it possible to create rules programmatically via a public API? We
already have a (pretty complex) admin screen as part of our application
where users can build conditions and specify desired approval chains using
the UI, integrated with all our back end stuff (domain objects, permissions,
common look&feel, etc.). It would be a huge overhead to serialize these
rules into DRL/XML files/streams and then have the rules engine parse them
again....
JSR94 solves the problem of handling rules once they are read from rule
files, but there is nothing about creating and persisting rules, unless I
missed it.
thanks,
Marina
