Glassfish 2.1 vs Glassfish 2.1.1

I recently encountered an error on deployment for Glassfish v2.1.1. I developed my WAR on v2.1 and works properly.. Maybe there are just some libraries that are incompatible with 2.1.1. :) IASDeploymentException FTW!

Mercurial and #!CRUNCHBANG Linux

I thought getting this to work was difficult regarding the HG VIEW command. Well it seems not.
Here is how I got it to work.

Download mercurial

sudo apt-get install mercurial

Download wish

sudo apt-get install tk8.5

Add a ~/.hgrc file and add the following code:

[extensions]
hgk=

having hgk have an empty value allows it to search for the path itself.

Then go to your repository and type in

hg view

and there you go!

Quartz and Google Guice

Got a really hard time looking for resources from the net regarding its integration. But good thing i found this really helpful link from another blog. quartz&guice

Also, I needed to get the injections working within my job. Also took me time to realize what to really search for.. My workaround was to pass the Injector object to the jobDataMap of the jobDetail.

jobDetail.getJobDataMap().put("Injector", jobFactory.guice);

And within my Job class, i can use the getInstance of the injector. :)

Injector guice = (Injector) arg0.getJobDetail().getJobDataMap().get("Injector");

So those objects that handle my Storage and some of my utils are done like this.

mailSender = guice.getInstance(MailSender.class);
loadersStorage = guice.getInstance(LoadersStorage.class);

Here's what my quartz code looks like.


QuartzScheduler

public class QuartzScheduler {

private final Scheduler scheduler;

@Inject
public QuartzScheduler(final SchedulerFactory factory, final GuiceJobFactory jobFactory) throws SchedulerException, ParseException {
   scheduler = factory.getScheduler();
   scheduler.setJobFactory(jobFactory);
   //...
   JobDetail jobDetail = new JobDetail("myJob", null, FileWatcherJob.class);
   jobDetail.getJobDataMap().put("Injector", jobFactory.guice);
   CronTrigger trigger = new CronTrigger("myCronTrigger", "cronGroup");
   trigger.setCronExpression("your cron expression");
   trigger.setStartTime(TriggerUtils.getEvenMinuteDate(new Date())); // start on the next even minute
   trigger.setName("myTrigger");
   scheduler.scheduleJob(jobDetail, trigger);
//        scheduler.start();
}

public final Scheduler getScheduler() {
   return scheduler;
}

public void shutdown() {
   try {
       scheduler.shutdown();
   } catch (SchedulerException e) {
       // ... handle it
   }
}

public void start() {
   try {
       scheduler.start();
   } catch (SchedulerException ex) {
       Logger.getLogger(QuartzScheduler.class.getName()).log(Level.SEVERE, null, ex);
   }
}

GuiceJobFactory

public class GuiceJobFactory implements JobFactory {

public final Injector guice;

@Inject
public GuiceJobFactory(final Injector guice) {
   this.guice = guice;
}

public Job newJob(TriggerFiredBundle bundle) throws SchedulerException {
   JobDetail jobDetail = bundle.getJobDetail();
   jobDetail.getJobDataMap().put("Injector", guice);
   Class jobClass = jobDetail.getJobClass();
   Job job = (Job) guice.getInstance(jobClass);
   guice.injectMembers(job);
   return job;
}
}

Quartz Module

public class QuartzModule extends AbstractModule {

@Override
protected void configure() {
   bind(SchedulerFactory.class).to(StdSchedulerFactory.class).in(Scopes.SINGLETON);
   bind(GuiceJobFactory.class).in(Scopes.SINGLETON);
   bind(QuartzScheduler.class).in(Scopes.SINGLETON);
}
}

My Job

public class FileWatcherJob implements Job {
//... declarations here
public void execute(JobExecutionContext arg0) throws JobExecutionException {
   System.out.println("Execute");
   try {
       Injector guice = (Injector) arg0.getJobDetail().getJobDataMap().get("Injector");

       mailSender = guice.getInstance(MailSender.class);
       loadersStorage = guice.getInstance(LoadersStorage.class);
       entityManagerFactory = guice.getInstance(EntityManagerFactory.class);
       persistenceContextHelper = guice.getInstance(PersistenceContextHelper.class);
       long newTimeStamp = file.lastModified();
       if (FileWatcherJob.timeStamp != newTimeStamp) {
           FileWatcherJob.timeStamp = newTimeStamp;
           onChange(file);
       }
   } catch (NullPointerException ex) {
       ex.printStackTrace();
   }
}

public void onChange(File file) {
   //some logic
}
//...
}

Blackberry Javaloader

For faster loading of apps for blackberry use this simple commands.

Pre-reqs: Set up environment variable for jde's bin folder.

1. Right Click on My Computer

2. Click Properties

3. Go to Advanced tab

4. Click Environment Variables

7. Click on Edit

8. Add path of jde's bin folder (e.g. C:\Program Files\Research In Motion\bin)

9. Click Ok.

Now you can go to command line:

To load the cod file to the device:

javaloader -usb load .cod

To erase the cod file from the device:

javaloader -usb erase -f .cod

To get the event log for debugging:

javaloader -usb eventlog > dumpfile.txt

Note:

replace the to your apps file name

replace dumpfile with any file name you want.

Enjoy!
