Step 8 : ARM 4.0 Java Hello World example

Now we are prepared to measure our transaction with ARM:

We call the start() method of our ArmTransaction object to start the transaction measurement
After our transaction is complete we call the stop() method passing the status how our transaction completed:
1. STATUS_GOOD - indicates the transaction executed successfully

01: import org.opengroup.arm40.transaction.*;
02: 
03: public class HelloWorld  {
04: 
05:     public static void main(String argv[]) throws Exception {
06: 
07:         ArmTransactionFactory tranFactory;
08:         if ((tranFactory = getTranFactory())==null) {
09:             System.exit(-1);
10:         }
11:         ArmApplicationDefinition appDef = 
12:             tranFactory.newArmApplicationDefinition("HelloTranApp", 
13:                                                     null, null);
14:         ArmTransactionDefinition tranDef =
15:             tranFactory.newArmTransactionDefinition(appDef, "HelloWorldJava",
16:                                                     null, null);
17:         ArmApplication app = 
18:             tranFactory.newArmApplication(appDef, "Examples", null, null);
19:         ArmTransaction tran = tranFactory.newArmTransaction(app, tranDef);
20:         tran.start();
21:         System.out.println("Hello world!");
22:         tran.stop(ArmConstants.STATUS_GOOD);
23:         System.exit(0);
24:     }
25: }
