Application Developers And Globalized Applications
Application Developers And Globalized Applications
Considering the factors mentioned in the previous blog posts, it is evident that organizations will focus on people with globalized application development or management skills. Hence it is very important that the developer community is enabled with this skill.
Requirements in future could be to globalize an existing product or develop new product for a global market. The subsequent posts provide the various facets of globalized applications leveraging the skills that are already known to the developer community.

Asynchronous application events in Grails
Asynchronous application events in Grails
On the project for my current client weve been using JMS in a rather naïve way for some time now. Weve also experienced a certain amount of pain getting JMS and ActiveMQ configured correctly. However, all were really using JMS for is asynchronous event broadcasting. Essentially we have a handful actions such as flushing hardware caches and notifying external systems that take place when a document changes. We dont want these things blocking the request thread when users save data.
After wrestling with JMS one too many times we decided to take a look at Springs event framework instead. It turns out its extremely easy to use for these kinds of asynchronous notifications in a Grails application.
Essentially any artefact can publish an event to the Spring application context. A simple publishing service can be implemented like this:
import org.springframework.context.*So a Grails domain class can then do something like this:
class EventService implements ApplicationContextAware {
boolean transactional = false
ApplicationContext applicationContext
void publish(ApplicationEvent event) {
println "Raising event $event in thread ${Thread.currentThread().id}"
applicationContext.publishEvent(event)
}
}
def eventServiceGrails services make ideal ApplicationListener implementations. As services are singleton Spring beans they are automatically discovered by Springs event system without any configuration required. For example:
void afterInsert() {
eventService.publish(new DocumentEvent(this, "created"))
}
void afterUpdate() {
eventService.publish(new DocumentEvent(this, "updated"))
}
void afterDelete() {
eventService.publish(new DocumentEvent(this, "deleted"))
}
import org.springframework.context.*Of course, multiple listeners can respond to the same events.
class EventLoggingService implements ApplicationListener<DocumentEvent> {
boolean transactional = false
void onApplicationEvent(DocumentEvent event) {
println "Recieved event $event in thread ${Thread.currentThread().id}"
}
}
If you run the code you will notice that by default Springs event system processes events synchronously. The EventService and ApplicationListener will print out the same Thread id. This is not ideal if any of the listener implementations might take any time. Luckily its easy to override the ApplicationEventMulticaster bean in
resources.groovy so that it uses a thread pool:import java.util.concurrent.*Running the code again will show the event being published in one thread and consumed in another. If you have multiple listeners each one will be executed in its own thread.
import org.springframework.context.event.*
beans = {
applicationEventMulticaster(SimpleApplicationEventMulticaster) {
taskExecutor = Executors.newCachedThreadPool()
}
}
Oddly, I would have thought it was possible to override the taskExecutor property of the default ApplicationEventMulticaster in
Config.groovy using Grails property override configuration, but I found the following didnt work:beans {
applicationEventMulticaster {
taskExecutor = Executors.newCachedThreadPool()
}
