Yes, instead I don't want to write any DRL file..... I want to create Rule
directliy in PackageBuilder object , instantiate it and run the rule
through it.
If it is not possible then I want to create drl file once and later on I
have to modify PackageBuilder from my Java code or program code.
is there any information regarding it is available.
Thanks & with Regards

You cannot change a rule once its created, but you can add the rule
again which will over-write the old version. If you don't want to use
drl you can build your AST, via the descr objects directly, however this
is not for the faint hearted its considered very experience developer
stuff. Personally I would use a templating language to generate your
drls, based from what ever objects you have that are codifying your rules.

modify rule definitions?

Thanks Anstis,
for your clarification. Is there a way that I can directly manipulate
directly this "PackageBuilder" from my JAVA code . Instead of updating drl
file.
Thanks & Regards,
Abhi..

I think you might misunderstand.
A DRL file contains text defining rules. Each DRL file is assigned a
package
name (much like Java).
The DRL file is loaded, parsed (PackageBuilder) and converted into a
Package
instance. Packages are added to RuleBases from which WorkingMemory can be
obtained for rule execution.
There is no "pkg" file - the Java Package can be converted into a stream
using Java's ObjectOutputStream.
Have a look at "1.6. The Drools Rule Engine - 1.6.1. Overview" in the
excellent documentation.
