Is it possible to programmatically add a rule at Runtime in Drools 6?
I have a StatefulKnowledgeSession based on some existing rules.
I just want to add a couple of rule the the main agenda group of the above
package, is this possible? Are there any examples or can someone point me in
the correct direction for documentation. The main drools 6.0 documentation
does not cover this.
Thanks

Yes, it’s now much simpler than before.
1) Create your original project with rules, build and deploy the jar.
2) Load the JAR to create a KieContainer.
3) add or change rules. Change the maven version, build and deploy the jar.
4) Ensure the JAR is in the KieRepository, or available to maven if using kie-ci, and call
KieContainer.updateToVersion( ReleaseId).
This will ensure your KieContainer is updated, and all existing stateful sessions will be
incrementally updated too. Assuming no bugs :)

This need to be a pragmatic operation and not achieved via a code release. I
can not see how this can be done using the new Kie interfaces without
storing the DRL on the filesystem. Am I missing something or can I still
continue to use the Drools 5 API's?

You can build KieModules programmatically too, in memory - without touching disk.

Here is a code example of creating kie modules in memory and upgrading
existing kbases/ksessions:
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test...
It is a test case, but maybe it will be easier to follow. We are working
on additional ways of doing similar things as well.
