[JBoss Seam] - Re: How to disable transactions when rendering an error page

by IGx89

Also, if <core:init debug="true"/> is set in components.xml, an infinite loop would seem to be unavoidable, since it causes jboss-seam-debug-2.0.0.CR1.jar!/META-INF/debug.xhtml to be rendered on every error. Not a huge deal since the developer will usually realize an infinite loop is going on when the page goes blank and their server log starts exploding in size, but still a pain (and a potential put-off for less experienced developers).

[Performance Tuning] - Re: JBoss AS Freezes with 99.9% CPU After 1 Hour in Producti

by PeterJ

It would appear that you installed the 32-bit JVM, not the 64-bit. I also verified that your JVM is interprting the Jvaa byte code and not compiling it. Where did you get this JVM?

If you mean pages.xml, then don't use that for a database error but let it bubble up to the web.xml exception handler.

[Installation, Configuration & DEPLOYMENT] - How to isolate my class from the lib jar

by alessandro_rizzi

Problem: I need to use an old version of Hibernate3.jar but in JBoss 4.0.4 there is a new version that I do not want Solution 1: delete Hibernate3.jar from \lib folder. Works, but it's so ugly. I've tried to add in my jboss-app.xml: <loader-repository> jboss.test:loader=my.ear <loader-repository-config> java2ParentDelegation=true </loader-repository-config> </loader-repository> But, nothing changes, I see that \lib jar are seen before mine. (I've made a test class with same name but different behaviour in the \lib folder and in my ear folders and I see the \lib one) If I write java2ParentDelegation=true ... JBoss do not start at all, because during deploy of my.ear I need, of course, some of the \lib jars of JBoss. My .ear is somehow "strange" because I do have many subfolders and the path of them is written in the jboss-service.xml of the .sar (inside .ear), using the classpath tag. Thanks for any suggestion.

[JBoss Seam] - Re: How to disable transactions when rendering an error page

by christian.bauer＠jboss.com

Actually, any page that is not rendered by the JSF servlet should be fine. The Seam servlet web-filter does not start transactions (ie. you need to call UserTransaction in a custom servlet if you want that). I don't know what an "annotated exception class" is.

[JBoss Seam] - Re: seam and batch/queue-processing

by motte79

No, i don't think so ... I need something like the following PseudoCode: | @Stateful | @Startup | @Name("batch") | @Scope (ScopeType.APPLICATION) | @TransactionManagement (TransactionManagementType.BEAN) | public class BatchBean implements Batch { | | private AtomicBoolean atomicBoolean = new AtomicBoolean(); | | // Stateless bean | @In IncomingMessages incomingMessages; | // Stateless bean | @In Task task; | @Resource SessionContext sessionContext; | | @Asynchronous | @Create | public void parent () { | | atomicBoolean.set(Boolean.TRUE); | task.init (incomingMessages); | | while (atomicBoolean.get()) { | | try { | Thread.sleep(100); | } catch (InterruptedException ie ) { | // nothing | } | | | while (atomicBoolean.get()) { | UserTransaction tx = sessionContext.getUserTransaction(); | try { | tx.begin(); | Object o = incomingMessages.next(); | if (o != null) { | // synchonous call | task.doTask(o); | tx.commit(); | } else { | tx.commit(); | break; | } | } catch (Exception e) { | tx.rollback(); | } | } | } | } | | @Shutdown | public void destroy () { | task.finishLastMessageAndClose(); | atomicBoolean.set(Boolean.FALSE); | } | } | @Shutdown is called before @Destroy and @Remove on undeployment and server-shutdown This approach is not possible because an applicationbean cannot be invoked by two different threads at the same time ... (the parent- and the destroy-method) Second there is no @Shutdown which waites for the asynchronous 'parent'-method to finish after invokation of the @Shutdown - method ... As asked in another thread i had also problems to get BEAN-managed transactions work with seam-components .. For the most components i need CONTAINER-managed Transactions, therefore i've installed <transaction:ejb-transaction/> in components.xml The MBean - approach above (Fri Sep 21, 2007 10:41 AM) creates a simple Thread, initialize it with the beans and have it run, but this has the sideeffect, that the method-invokations incomingMessages.next() and task.doTask() are running both in there own transactions ... that could cause the loss of messages ... ). As described before there is also a problem to synchronize the MBean with the Component-creation (Task, IncomingMessages) because the MBean is earlier up than seam. And second the MBean lives on shutdown and on undeploy longer than seam .. Maybe i'm mixing some concepts which should better stand alone .. I've not much experience with EJB3, Jboss, etc. ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088956#4088956 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4088956
