How to add drl file as string without writing with KieFileSystem ??

[Adarsh22X22Singh]

                        KieServices ks = KieServices.Factory.get();
			KieContainer kContainer = ks.getKieClasspathContainer();

			KieSession kSession = kContainer.newKieSession("ksession-rule");

So here i do not want to use " kContainer.newKieSession("ksession-rule"); " to read drl.

I have the rules in String i.e. String drl="Rules";

So what should i do for that ??

If you have your drl code in a Java String the quickest thing to do to create a KieSession out of it is using the KieHelper as it follows:

String drl = ... // your drl is here
KieSession ksession = new KieHelper().addContent(drl, ResourceType.DRL).build().newKieSession();

Note however that the KieHelper is not in drools public API and the it may be subject to change without any warning.

Thank you so much Mario,

I have few questions..

1 - what various formats of rule file is accepted by Drools ?? As I know .drl, .xls. So does it accept Json or Xml ??

2 - Can we write loop in drl file ?

3 - Is there any editor in which we can define the rules in guided table and download the source as .drl file?

The Guided Decision Table Editor produces a "gdst" file that is recognised by KieHelper. See the ResourceType enumeration for different types.

That said you won't be able to download any source from the Workbench. You'll need to clone the repository and extract the source file yourself.
