[Design the new POJO MicroContainer] - Re: Reflection and MetaDataRepository refactoring

by adrian＠jboss.org

Tomorrow I'm going to upgrade the MC project to the new jboss-reflection and jboss-mdr projects. Unfortunately, I didn't catch Alex before he left the office to get approval for a jboss-xb release, so I'll do a snapshot until I can speak to him next week. I also want to put some JBossXB testsuite support in JBossXB so each project doesn't have to write their own jbossxb test harness like we do now, so that's probably not a bad thing anyway since it isn't done yet. Once I've completed this, the other projects will (hoperfully :-) be lot a easier since they are already in a sane state unlike the tangled web that the container project had become. ;-) We can also remove the schema initialization hacks from our test code since that will be provided by JBossXB factory settings.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Another way to write clustered singletons

by sebastianlacuesta

Excellent. I want to call a method of a singleton service. I tried using an RMIAdaptor this way: | public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { | PrintWriter out = response.getWriter(); | String numero = request.getParameter("numero"); | String mensaje = request.getParameter("mensaje"); | try { | Context context = new InitialContext(); | RMIAdaptor rmiAdaptor = (RMIAdaptor)context.lookup("jmx/rmi/RMIAdaptor"); | if ((rmiAdaptor != null) && (rmiAdaptor.isRegistered(new ObjectName("poksmedia.mbean:service=MBloxService")))) { | rmiAdaptor.invoke(new ObjectName("poksmedia.mbean:service=MBloxService"), "sendMessage", new Object[]{numero, mensaje}, new String[]{"java.lang.String", "java.lang.String"}); | out.print("El mensaje se enviÃÂ³ correctamente (creo)."); | } | } catch (NamingException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (MalformedObjectNameException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (NullPointerException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (InstanceNotFoundException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (MBeanException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (ReflectionException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } | } | This works awesome in the same node where the service is running. But not in the others. It throws a javax.management.RuntimeMBeanException . Any ideas?

[Design the new POJO MicroContainer] - Re: enums, generics and other animals

by adrian＠jboss.org

Why have you created a package called "enums"? That's just stupid. Packages should be based on what they provide not what there contents are. Would you create a package called "classes"? :-) e.g. The metatype project has org.jboss.metatype.api - annotations - types - values I think a package called "annotations" is stupid as well, but it seems to be a convention. :-) Either put the enums in the annotations package or create a package called model or something. This package would also contain callback interfaces referenced (like the ScopeFactory in the metadata repository) so calling it "enums" is plain wrong. A couple of related issues now that I look at the annotations: 1) Why do you have class names as strings in the annotations? To be able to read the annotations at all the classloader must exist so there's no problem with letting the users specify classes. 2) How can the Factory(Method) annotations work? These are used at object construction. You don't know the type until the object is constructed so how can read the annotations? :-) I could understand it if this was somehow used to annotation a package with what beans need constructing and how to do it. e.g. | @Beans | ({ | @Bean(name="blah", class=MyBean.class), | @Bean(name="blah2", factory=MyFactory.class, method="create") | }) | package com.acme; | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4134935#4134935 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4134935
