Step 4 : ARM 4.0 Java Hello World example
Description
Now that we have a transaction factory instance we can begin creating
all necessary ARM objects to communicate with the ARM agent: We create
an ArmApplicationDefinition instance using the newApplicationDefinition()
method of the ArmTransactionFactory interface representing our application
and pass the following parameters:
- our application name
- null object reference for the ArmID parameter so the agent
generates an ID for us.
- null object reference for the ArmIdentityProperties parameter
because there are no additional identity properties.
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: ArmApplicationDefinition appDef =
12: tranFactory.newArmApplicationDefinition("HelloTranApp",
13: null, null); |
14: System.out.println("Hello world!");
15: System.exit(0);
16: }
17: } |
