[Management, JMX/JBoss] - Re: Invocation Statistics of EJB

by PeterJ

The best place to look for sample code is at the source code for twiddle, which is the command-line equivalent of jmx-console. The source can be found in the JBossAS source at console/src/main/org/jboss/console/twiddle[/command]. Look especially at the execute() methos in the *Command classes. For a quick start, and example JMX code can be found at http://wiki.jboss.org/wiki/Wiki.jsp?page=HowDoIGetRemoteAccessToMyMBean And the JMX docs are at http://java.sun.com/j2se/1.5.0/docs/guide/jmx/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4052624#4052624 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4052624

[EJB 3.0] - Issuing Commands to a Running Process

by suatkaya

Hi, For some reason, my stateless session bean starts a long running "process" (not in OS terms) like this code: | private @Resource SessionContext sctx; | ..... | sctx.getTimerService().createTimer(1, obj); | The long running process is in timer code. And it creates a Queue object and gives it a JNDI name like this: | @Timeout | public void timeoutHandler(javax.ejb.Timer timer) | { | InitialContext inictx = new InitialContext(); | this.commandQueue = new ConcurrentLinkedQueue<SomeMsg>(); | inictx.bind("CmdQueue", this.commandQueue); | } | And this created queue is used to accept commands from other session beans, like this: | SomeMsg msg = this.commandQueue.poll(); | And then acts accordingly. Other session beans can send a message to this process like the following: | InitialContext ctx = new InitialContext(); | Queue<SomeMsg> queue = (Queue<SomeMsg>) ctx.lookup("CmdQueue"); | queue.add(msg); | And the process unbinds the name before finishing. Are there any pitfalls in this approach?

[JBoss Seam] - Question about explicit conversation id

by bsmithjj

I have the following SeamTest (FacesRequest) method: | @Override | protected void invokeApplication() throws Exception { | | AccessRequestManager2 arm2 = (AccessRequestManager2) getInstance("accessRequestManager2"); | assert arm2 != null; | arm2.startRequest(); | log.info("conversationId = "+getConversationId()); | | } | | and AccessRequestManager2.startRequest() looks like this: | @Begin(id="#{draftAccessRequestMaster.id}",join=true) | public void startRequest() { | log.info("draftAccessRequestMaster.id = "+draftAccessRequestMaster.getId()); | } | Furthermore, I use the @Factory pattern to create a persistent instance of draftAccessRequestMaster which is @In(jected) to AccessRequestManager2. When I run the test, I get the following in the log output: | 10:36:40,265 INFO com.evergreen.accesscontrol.AccessRequestManager2Test.(info:94) - updateModelValues() | 10:36:40,812 INFO com.evergreen.accesscontrol.impl.AccessRequestManager2Bean.(startRequest:54) - draftAccessRequestMaster.id = 5 | 10:36:40,875 INFO com.evergreen.accesscontrol.AccessRequestManager2Test.(info:94) - conversationId = 1 | My question here is .... Why isn't the conversationId equal to the explicit id that I created in the @Begin(...) annotation?

[JBoss Seam] - Re: What is the common pattern for selecting objects?

by grettke_spdr

The vision is that in case we don't want to use enums to populate selection controls we could use objects instead, but those objects don't yet need to be persisted.

[JBoss AOP] - Re: How to avoid intercepting recursive calls

by system.out

Thanks Kabir, I think it can be an option. I have 2 questions now: 1. How can I exclude the first method call from <not-called> list. i.e. in my previous example, prepare() won't be intercepted if I have all 3 methods in <not-called> list? Is that correct? 2. Can <not-called> be applied at class level/package name?

by adrian＠jboss.org

I guess this would be an alternative to the KernelControllerContextAware interface? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4052619#4052619 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4052619

You appear to be one of those people that can't even format a question in a way that is answerable it's no wonder you've got a problem: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossHelp In particular http://wiki.jboss.org/wiki/Wiki.jsp?page=HelpExpertSystem Your post falls under the http://wiki.jboss.org/wiki/Wiki.jsp?page=BadPostItDoesNotWork category of useless posts.
