Pineapple core component – How-to: Create the core component with result listeners registered

How-to: Create the core component with result listeners registered

Use the com.alpha.pineapple.CoreFactory to create an instance of the core component with result listeners registered.

The purpose with registration of result listeners prior to initialization of the core component is to receive notifications during initialization of the core component.

Implement a result listener

Use an existing listener og implement the com.alpha.pineapple.execution.ResultListener interface which is defined in the pineapple-api project:

public class LoggingListenerImpl implements ResultListener
{
    /**
     * Logger object.
     */
    Logger logger = Logger.getLogger( this.getClass().getName() );

    public void notifyOfResultStateChange(ExecutionResult result) {     
    {
        // log debug message
        if (logger.isDebugEnabled()) {
            StringBuilder message = new StringBuilder();
            message.append( "Received notification <" );
            message.append( result.toString() );
            message.append( ">." );            
            logger.debug( message.toString() );
        }
    }

}

Register the result listener with the core component

In your client of choice, create the core component and register the listener:

  // create the listener 
  ResultListener listener = new LoggingListenerImpl ();
  ResultListener[] listeners = { listener };     

  // create core component
  CoreFactory coreFactory = new CoreFactory();
  PineappleCore core = coreFactory.createCore( listeners );

Invoke an operation to receive notifications

In your client of choice, invoke an operation:

  
  // get user.home
  String userHome = System.getProperty( "user.home" );
        
  // define default pineapple runtime directory
  File runtimeDirectory = new File( userHome, ".pineapple" ); 
         
  // define modules directory
  File modulesDirectory = new File( runtimeDirectory, "modules" ); 
        
  // setup parameters
  String operation = "run-tests";
  String environment =  "production-2-a"; 
  String module = "jee-platform-infrastructure-tests" ; 
    
  // execute operation
  Future<String> future;
  future = core.execute( operation, environment, modulesDirectory, module );

  // invoke get-method to block until execution is complete
  String result = future.get();

And look in your Log4j log to inspect the notifications...
