Hi, I am new to Drools and Guvnor and I have the following query: 1. I have uploaded a pojo model jar which has a class A containing a hashmap<String, String> attr1. 2. Then, I created a new rule- Guided decision table. 3. And i want to define a rule lets me select a key of the hashmap defined using the drop-down pop-up and check the corresponding value in the second column. Then perform an action. Example: check Key= "Name" and value="Abc". then set an output string- "Name ok" in action. Please provide any suggestions.
