@Singleton @Startup fully Asynchronous?

由 ε祈祈猫儿з 提交于 2019-12-08 06:24:34
问题 I am using the @Singleton and @Startup annotations together to create a long running process. By using these annotation can I safely assume that my process will be a single thread running fully asynchronously? 回答1: You can use these annotations just at the class-level, so I'm not sure what 'process' do you refer to (@PostConstruct method?) I don't remember any part of the EJB 3.1 specification which talks about the required asynchronous singleton initialization. 4.8.1 Singleton Initialization

Simulate a start up: Android Emulator

由 谁说胖子不能爱 提交于 2019-12-08 06:19:38
问题 I coded an app which starts at the system start up and starts a service which is written in the code. The code is working fine and the service is getting started when the app is installed on a real android device but not on an emulator. I do not have a real device always handy. Any idea how to simulate a start up in an emulator? 回答1: I just found a way to simulate a start-up without having to stop-and-start the emulator. Go to the DDMS perspective (if you are using Eclipse) and "stop" the

How to write Gradle startup script

由 蓝咒 提交于 2019-12-08 06:11:15
问题 I have a Gradle app that I startup using ./gradlew run . This works fine, but I'm trying to deploy to an AWS instance (Ubuntu 12) and I would like the script to execute on boot. I tried writing a startup.sh file with the above command, but no dice. I've also tried adding the command to the /etc/rc.local file, but that doesn't seem to work either. Can someone give me an idea as to how to execute `./gradlew run' on startup? Thanks! 回答1: I wrote the following init script for starting gradle

Is there something like a ServletContextListener in JSF?

由 早过忘川 提交于 2019-12-07 19:36:33
问题 I would like to listen if a JSF application is started or stopped like as possible with a ServletContextListener in a plain Servlet web application. How can I achieve this? 回答1: You can use an @ApplicationScoped @ManagedBean which is eagerly initialized and annotate the desired startup/shutdown hook methods with @PostConstruct and @PreDestroy respectively. So: @ManagedBean(eager=true) @ApplicationScoped public class App { @PostConstruct public void init() { // ... } @PreDestroy public void

Starting R and calling a script from a batch file

由 给你一囗甜甜゛ 提交于 2019-12-07 17:47:47
问题 I have an R-based GUI that allows some non-technical users access to a stats model. As it stands, the users have to first load R and then type loadGui() at the command line. While this isn't overly challenging, I don't like having to make non-technical people type anything at a command line. I had the idea of writing a .bat file (users are all running Windows, though multi-platform solutions also appreciated) that starts R GUI, then autoruns that command. My first problem is opening RGui from

Run startup code in the parent with Django and Gunicorn

由 本小妞迷上赌 提交于 2019-12-07 17:35:39
问题 I need my code run at Django application startup, before Django starts listening for incoming connections. Running my code upon the first HTTP request is not good enough. When I use Gunicorn, my code must run in the parent process, before it forks. https://stackoverflow.com/a/2781488/97248 doesn't seem to work in Django 1.4.2: it doesn't run the Middleware's __init__ method until the first request is received. Ditto for adding code to urls.py . A quick Google search didn't reveal anything

问题 There is a interface DispatcherListener in Struts2. The docs says "A interface to tag those that want to execute code on the init and destroy of a Dispatcher ." But how to use this interface. If I create a class that implements this interface, how should I configure it to Struts2? 回答1: When a Dispatcher is instantiated, it could send to the listener notification when it's initialized or destroyed. The reference and code samples are from here. The simple usage is to instantiate a bean by the
