read drl files from filesystem

[Drools User]

Hello,

I am able to execute rules when they are placed in classpath . Is it possible to read rules(*.drl files) from filesystem?

Is it possible to mention the file path in kmodule.xml?

[Abhijit Humbe]

We can load file rule from filesystem using 'KieFileSystem', like as:

===============

KieFileSystem kfs = kieServices.newKieFileSystem();
File file = new File("path/to/Sample.drl");
Resource resource = kieServices.getResources().newFileSystemResource(file).setResourceType(ResourceType.DRL);
 kfs.write( resource); 
KieBuilder kb = kieServices.newKieBuilder(kfs);
 kb.buildAll();
===============

Give a try with this approach.
