ejb-3.1

问题 I have a problem with EJB3.1 Timer service. I find this issue quite strange! I have a stateless session bean like below deployed on JBoss7.1.1 application server. import javax.annotation.Resource; import javax.ejb.Local; import javax.ejb.Remote; import javax.ejb.Stateless; import javax.ejb.Timeout; import javax.ejb.Timer; import javax.ejb.TimerService; import javax.interceptor.Interceptors; @Stateless @Local(HelloUserLocal.class) @Remote(HelloUserRemote.class) public class HelloUserBean

问题 i have to run two methods one after another for every 10 minutes using @schedule annotation in ejb. my code is like: @Schedule(minute="*/10") public void mth1() { System.out.println("welcome"); } @Schedule(minute="*/10") public void mth2() { System.out.println("hello"); } how to proceed? Thanks for ur reply..but,the timer is set for 10 minutes for both mthds separately.2nd mthd starts to execute after 1st mth completes,. if i call 2nd mthd in 1st mthd both are run within 10 min ..i want to

问题 I have a Stateless session bean with two @Schedules : @ConcurrencyManagement(ConcurrencyManagementType.CONTAINER) @Stateless @Lock(LockType.WRITE) @AccessTimeout(value = 0) public class ScheduledTask { @EJB private SomeClass sClass; @Schedules({ @Schedule(hour = "*", minute = "*/10", info = "Automatic timer to send")}) public void send() { sClass.doWork(true); } @Schedules({ @Schedule(hour = "*", minute = "*/35", info = "Automatic timer to receive")}) public void receive() { sClass.doWork

问题 When an ear would contain two ejb modules modulea.jar and moduleb.jar. And modulea.jar contains an @Startup ejbX, that calls another ejbY, which is not an @Startup ejb, from moduleb.jar during the startup of the bean X it is required that moduleb.jar is started first as otherwise the app server is not able to inject X into Y. But how to ensure that moduleb.jar is started first? Currently I have this problem in WebSphere, but I can't seem to find a way to enforce an order. Is there something

问题 May be the best way is doing it manually. But in a large project you need some tool to assist you. It was the idea that led me to search a tool. Are there any EJB migration tools available for migrating EJB 2.0 to 3.x. 回答1: It was only under development for a short time, but for a period we did have an eclipse plugin that would read in ejb-jar.xml files and then update the source and insert the annotations. It's been used a handful of times by the person who wrote it (Jonathan Gallimore) and

问题 We have Glassfish cluster which has two instances. On this cluster one my EJB application is deployed and running. Now I have another EJB-Timer-application which I want to deploy on Glassfish server(domain) not on cluster then I want to access the cluster's EJB. AS per my understanding EJB timer could not deployed on a cluster because it could be run on both the instances of cluster. What are the possible ways to access it ? Thanks 回答1: You can actually deploy EJB timers on a cluster. They

问题 I'm wondering why ejb injection into JAX-RS resource (RestEasy on JBoss7) is not working. EJBs are not part of war but its own EJB jar but I supposed this should not be the problem. I'm forced to do the ctx.lookups "workaround", which are not pretty. Am I missing something or it is really not supported to inject EJB like that? Example below does not work with JBoss, but works with Glassfish (sadly I gotta run my application on JBoss) Path("x") @RequestScoped public class UserResource {
