Hi, I have a real basic question about the working of drools. I figured it to be this way: We load our input data (our facts) - fire the rules on this data - get the modified out put in our output file. Doubt: I am reading all my input data from a text file. 1. How can I load all the data contained in my text file into the memory at the same time? Like we used HSSF workbook concept for the excel file? And fire all the rules at the data at once.? 2. Again When I have multiple input files, Shouldn't I be loading all the input files in the memory and firing rules on them? How can I do that? I should have different test files for different input datasets?? (for example like the ExcelDataRulesTest.java file in the example) I am still stuck with the procedural way of thinking- read lines and run rules and generate output. Please help!!! I am really new to this and going round and round. Thank you.
