[Messaging, JMS & JBossMQ] - Re: XA Recovery of messages sent to a Topic

by mmusgrov

Actually, I did not install any durable subscribers for the Topic and consequently there was nothing to recover. When I added a durable subscriber and retested then the recovery system did indeed recover the message published to the topic. So the JBossMQ recovery support is working provided we register the appropriate JMS recovery provider (as per JIRA issue http://jira.jboss.org/jira/browse/JBTM-279).

[JBoss AOP] - Re: Can i have interceptor on throw exception?

by flavia.rainone＠jboss.com

Hi, You can do this with the new after-throwing typed advice. Examples can be found in our tutorial, and a more detailed documentation is available in our User Guide. If you are using 1.5GA, you will have to wait till our next 2.0.0GA release, which fortunately is scheduled for the end of this week. If not, the feature is available in our CR releases.

[JBoss AOP] - Re: Interaction Jboss AOP with a Java Application

by flavia.rainone＠jboss.com

Hi! Yes, you can add an interceptor at runtime through dynamic AOP. For that, the classes you want to affect dynamically must be prepared through "prepare" expressions, like this: <prepare expr="all(org.mypackage.Pojo)"/> | <prepare expr="execution(* org.mypackage.Pojo2->method()))/> | This must be done inside a jboss-aop.xml file. Alternativaly, you can annotate classes and methods you want to prepare with @Prepare. After that, you can either use aopc or loadtime weaving to transform your classes. This will basically prepare all joinpoints matched by the prepare expressions so that, at runtime, you can add an interceptor to them, and remove interceptors as well. Now, to add this interceptor at runtime, you must perform a call to AspectManager.addBinding() method. To take a better look at how this is done, you can look for calls to this method that are made inside org.jboss.aop.AspectXMLLoader class. I am planning to write a tutorial on this at our blog in a few weeks (http://jbossaop.blogspot.com/). There are also plans for writing a more user-friendly interface to add interceptors and aspects at runtime. So, stay tuned!

[JCA/JBoss] - Updatingd JDBC Datasources and container behaviour

by sankul123

Hi ALL, I want to add a new datasource[ex- oracle database DS object] and rebind to an existing JNDI name. I want to do this to achieve the following - -If there is any change in database schema password[manuually on database server], this should be updated to already existing datasource and rebind with existing JNDI name. If I do update datasource will this be picked by container to manage CMT ... Also I want to persist changes into {JBossHome}/server/default/deploy/oracle-ds.xml. Is there anyway I can take this -ds.xml inside my context[.ear] View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4147301#4147301 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4147301

[Persistence, JBoss/CMP, Hibernate, Database] - PersistenceContext and PerststenceUnit

by mohitanchlia

I have been looking around for a good description of PersistenceContext and PerststenceUnit but have not been able to get good tutorial that explains the concept. There is lot of code around but nothing that explain what it really means and why we need it.

[Beginners Corner] - Lifecycle management for 3rd party software connection

by gymshoe2

Hello, We have a 3rd party software component that we need to integrate into our EJB services. It can be somewhat expensive to establish a connection to this 3rd party software and we would also like to manage the number of connections that are attempted. (it is not a database) I understand that the concept of a singleton cannot really be implemented using EJBs because the container wants to manage the lifecycle of objects correct? What is the best way to create a wrapper around this 3rd party software? We will want calls made into the 3rd party library to be synchronous - we will not want to send a message and have it processed async. I understand this may be a bottle neck for overall server operation. You may ask: why are we using EJBs given this limitation? For consistency I guess. EJB communication is being used between the client/server for the bulk of the application. In this particular case the 3rd party software needs to be involved in order to satisfy the request. The client is unaware of the server issues.
