CAN I HAVE CLEAR IDEA ABT DROOLS RULE ENGINE THAT WORKS WITH JAVA.I GONE THROUGH DROOLS DOCUMENTATION. AND I UNDERSTOOD SOMETHING. BUT I WANT TO KNOW HOW TO WRITE RULES IN JAVA AND HOW THEY WORK UNDER DROOLS .....
First of all, please don't post in all uppercase letters. It is considered shouting (and thus rude) all over the 'net: KeepItDown
Secondly, this forum is for the questions about the JavaRanch site itself, not for questions about Java. So someone will move it to a more appropriate forum for you, where you're likelier to get help.
Now, as to your question, you need to be more specific. You said that you understood the documentation, but not how to write rules. I'm assuming that is covered in the documentation, so tell us in detail what about it you're having problems with.
