I want to know how can i change business process for document without stopping business process. is it posible? In real life we should able change process at runtime (e.g. found any bugs in business process or something else). well how can i change process in JBPM engine without undeploy it and not lost process context for documents? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523560#523560

[EJB 3.0] New message: "Re: @Serivce : Singelton EJB and reetrant calls"

by jaikiran pai

User development, A new message was posted in the thread "@Serivce : Singelton EJB and reetrant calls": http://community.jboss.org/message/523555#523555 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- > dastraub wrote: > > got the answer from the jboss developers via irc, thanks ! For the record - Here's what was discussed over IRC: (01:40:14 PM) danielst: @Service means, there is only one instance of this EJB, ok. EJB Spec. 4.7.11 says, the container must ensure that only one thread can be executing an ejb-instance (non reentrant instances). If I use an @Service, does the container serials the calls to this EJB ? Or throws an javax.ejb.ComcurrentAccessEcxeption ? (01:46:39 PM) Jaikiran: danielst: @Service is not the EJB3.1 @Singleton (01:46:48 PM) Jaikiran: @service was a jboss specific feature (01:47:45 PM) danielst: yes, I know - It's a JBoss extension. But how does this handle parallel calls to this ejb if there is only one instance ? (01:47:59 PM) wolfc: Jaikiran: in essence a service bean should behave very much like a singleton. Thread safety is one of the basics of EJB. (01:48:07 PM) wolfc: I'm not sure whether we actually guard for it though. :-) (01:48:25 PM) Jaikiran: wolfc: hehe, that's what i meant (i don't think we guard it) (01:50:48 PM) danielst: thanks for this hints ;-) - I don't use this by my self, I have to review some other sources and looking for arguments ... (01:52:11 PM) Jaikiran: danielst: pretty soon we will be having @Singleton support, which will obviously be spec compliant (01:54:22 PM) You are now known as Jaikiran|Lunch (01:54:46 PM) danielst: @Singleton is EJB3.1, right ? (01:55:11 PM) Jaikiran|Lunch: danielst: yes (01:56:46 PM) danielst: yeah, I quickly read it now, there is also an @ConcurrencyManagement. (01:57:23 PM) Jaikiran|Lunch: yes allowing for bean managed/ container managed concurrency (02:01:23 PM) danielst: ok, as short summary : don't use the @Service because the behavior of concurrent calls is undefined ... and wait for ejb 3.1. Will the EJB 3.1 container works with an JBoss 4.2.3 (I guess not) ? (02:02:31 PM) Jaikiran|Lunch: EJb3.1 will be targeted against AS-6.0.x versions (02:02:57 PM) Jaikiran|Lunch: some of the initial features (like nointerface and deployment through .war) are available in the upcoming AS 6.0.0.M2 (02:03:11 PM) Jaikiran|Lunch: btw, 4.2.3 isn't fully EJB3 compliant (02:04:22 PM) Jaikiran|Lunch: if you are interested in EJB3.1, here's its current state for 6.0.0.M2 http://community.jboss.org/wiki/EJB31inAS600M2 -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523555#523555

I thought also JSP can be used for a task form, but I didn't find any information about it in the developers guide. How does the task definition look like? Should it look like <task name="name " form="http:localhost/8080/package/a_form.jsp"> ? Should the web app. deployed on the same server, in which jBPM runs?

[JBoss Tools] New message: "converting a Java project to Dynamic web project"

User development, A new message was posted in the thread "converting a Java project to Dynamic web project": http://community.jboss.org/message/523545#523545 Author : Arbi Sookazian Profile : http://community.jboss.org/people/asookazian Message: -------------------------------------------------------------- So I guess I must have a Dynamic web project and then add JSF capability in order for code assist to work. So I created a new Dynamic web project but it does not let me select an existing codebase like it does when I do a new Java project. So if I create a new Java project, can I then convert it to a dynamic web project? If yes, how? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523545#523545

User development, A new message was posted in the thread "Code assist does not work in dvdstore example": http://community.jboss.org/message/523544#523544 Author : Arbi Sookazian Profile : http://community.jboss.org/people/asookazian Message: -------------------------------------------------------------- What I just noticed is that if you create a Dynamic Web project you get a WebContent folder inside your project. If you create a Java project you get a WEB-ROOT folder instead. As long as I create a Dynamic Web project and add JSF capability, the content assist seems to work. Is this a requirement then to ensure CA works? You must have a Dynamic web project? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523544#523544
