Hi, We are importing excel in drool by using drool API. we are facing issue in applying multiple condition into various columns. Defined excel rule for one particular column but we are not able to get condition or rule in .drl file.below is the code. public class DroolExcelDemo { public static final void main(final String[] args) { // Create knowledge builder final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); // Create drl file from excel sheet InputStream is =null; try { is= new FileInputStream("C:/POCExcel.xls"); } catch (FileNotFoundException e) { e.printStackTrace(); } // Create compiler class instance SpreadsheetCompiler sc = new SpreadsheetCompiler(); // Compile the excel to generate the (.drl) file StringBuffer drl=new StringBuffer(sc.compile(is,InputType.XLS)); // Insert dialect value into drl file drl.insert(drl.indexOf("DROOLS")+40,"dialect \"mvel\""+"\n"); // Check the generated drl file System.out.println("Generate DRL file is showing below–: "); System.out.println("Value of xls in drl"+drl); // writing string into a drl file try { BufferedWriter out = new BufferedWriter(new FileWriter("C:/rules.drl")); out.write(drl.toString()); out.close(); //System.out.println("print content"+out.append(csq, start, end)); } catch (IOException e){ System.out.println("Exception "); } // Wait before using the drl file in the next section. try { Thread.sleep(10000); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("testing"); // End creation of drl file from excel sheet // Using DRL file kbuilder.add(ResourceFactory.newClassPathResource("rules.drl",DroolMessage.class),ResourceType.DRL ); // Check the builder for errors if ( kbuilder.hasErrors() ) { System.out.println("kbuilder has errors"); System.out.println( kbuilder.getErrors().toString()); } // get the compiled packages (which are serializable) final Collection pkgs = kbuilder.getKnowledgePackages(); can anyone help on this.
