[EJB 3.0] - Re: There is no default persistence unit in this deployment

by davestar

Thanks Everyone, the JIRA ticket can be closed. Thanks jaikiran! that worked when I moved the persistence.xml to the META-INF within the EJB jar. I also found that with my current structure of having persistence.xml at the top level META-INF within the ear, it works when I have the unitName for the @PersistenceContext annotation. Eg: @PersistenceContext(unitName=PERSISTENCE_UNIT_NAME) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4202576#4202576 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4202576

[EJB/JBoss] - Node Removal In mvcc-entity Cache Through JMX Console

by frank.stillford

When using the Entity Tree Cache in JBoss 4.2.2.GA, the JMX bean makes available a remove(String) method, that, when invoked, removes a given node from the cache. Following the JBoss 5.0.0.GA cache article (available: http://www.jboss.org/community/docs/DOC-13200), I have migrated to the mvcc-entity cache. Unfortunately, I am unable to find a way to remove nodes from this cache without redeploying the application. Being able to remove nodes (in particular, those cached as read-only) from the cache is a critical need when redeployment in a production environment is not a viable option. Is this functionality still available with the mvcc-entity cache? If not, are there any similar alternatives or workarounds?

[Beginners Corner] - Fedora 10, JBossAS-5.0.0.GA, OpenJDK 1.6 with jboss web-cons

by brad.simonin＠redhat.com

Hello. My Linux box is Fedora 10, JBossAS-5.0.0.GA, and OpenJDK 1.6. When I go into the JBoss web-console the applet on the left side has a nice pretty gray box and nothing else. The right side of the JBoss web-console has the JBoss information listed as it should. Firefox tells me the applet is started but nothing appears. Can some one point me in the right direction for what is wrong. I can run other Java Applets from other sites but as I said the web-console doesn't work. Thank you in advance.

[EJB/JBoss] - Recover EJB Stateful

by thiagomontovaneli

Hi, I have a EJB stateful working in my server Jboss 5.0. So, I cried one application Web for be a client of the EJB. In client project has two JSP pages, one for to list the content in EJB and the other for add in EJB. In jsp that working for to list, call the EJB, so: InitialContext ic = new InitialContext(); | CarrinhoHome home = (CarrinhoHome) ic.lookup("LivrariaEAR/CarrinhoEJB/home"); | Carrinho carrinho = home.create(); | this.total = carrinho.getTotal(); | this.livrosList = carrinho.getLivrosList(); | this.nome = carrinho.getNome(); And in jsp for to create, I do: public String AddCarrinho() { | try { | InitialContext ic = new InitialContext(); | CarrinhoHome home = (CarrinhoHome) ic.lookup("LivrariaEAR/CarrinhoEJB/home"); | Carrinho carrinho = home.create(); | this.total = carrinho.getTotal(); | this.livrosList = carrinho.getLivrosList(); | this.nome = carrinho.getNome(); | livro = new Livro(45, "Sujeiro"); | carrinho.addLivro(livro); | } catch (Exception ex) { | ex.printStackTrace(); | } | return "listLivro"; | } I need to find the same EJB for the jsp that list the content and the jsp that create the content. And for each client one EJB different. Help me please.

[Beginners Corner] - What to use when simple Thread neededd

by jaymcmeans

I am very new to this JBoss / J2EE stuff. But I know Java inside and out. We are creating a system that allows users to manage some telecom equipment. We doing this using JBoss 4.2 and Seam 1.2. I have a legacy system that I have to constantly poll to retrieve information. I need something that will constantly run so that I can regularly scrape information from it and store the results. It needs to do this process 24x7 regardless of whether someone is interacting with the system or not. In a normal Java application I would simply create a Thread and just scrape away. I have created a bean that has a scope of Application and has the @Startup annotation. That way it starts up when JBoss creates stuff. Inside the method associated with the @Create annotation I am spinning up a Thread and doing all of the scrapping work. This thread runs the whole time JBoss is alive. I also shut the thread down in the method associated with @Destroy. I have been told that I really should not create my own thread from within a Managed Bean. If that is the case then what is the best way to have something constantly running and gathering data independent of everything else? Because of my rookiness with this stuff, any examples would be greatly appreciated.

[JBoss Cache: Core Edition] - Configuration issue

by DanielTravin

Hi all, I have a object tree like this inside my jboss cache cluster /country/city So, there are many countries and many cities inside each country. I need to have only one JVM on the LAN that is aware of the whole object tree, so i use a default config for that. I also have a lot of other JVMs but they are logically linked to a "city" and "country" So, 1 single JVM can manipulate with only 2 nodes for example /Argentina/BuenosAires and /Argentina Basically i d like to say to cache "I want to replicate these nodes only Node1, Node2. Do not replicate other, i will not use them" What element in configuration is responsible for this?

by alesj

Btw, jndi binding was updated (as it was jmx): - http://anonsvn.jboss.org/repos/jbossas/projects/microcontainer/trunk/aop-... I think you just need to point this lifecycle-configure to use your real AspectManager. Afaik this is done via manager="RealAspectManager" attribute.
