There is UI already there to control rules. and perform operation like CRUD using drl file or even using dsl for easing making drl rules for nontech person for such operation. So, Is there any other way to create our own webpage to control such rules for even easy usability?
Is any way to edit source codes for available workbench UI?
Drools is open source and you can modify the UI if you want. You can also treat Drools like a component in your architecture by wrapping it in a service and calling it through your own simplified API. You can then call your API from your own web front end.
