Step 3 : ARM 4.0 Java Hello World example
Description
To operate with any ARM interface we need an initial object which
creates all other ARM related objects. Therefore we need an instance
of the ArmTransactionFactory interface. The getTranFactory()
static method tries to create such an object. There are several things
to consider by getting such an instance. For simplicity we assume this
method works fine here. If no such object could be instantiated we just
exit our example.
Code
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: System.out.println("Hello world!");
12: System.exit(0);
13: }
14: } |
