by jwenting

no, I'm saying that the way JBoss does things (i.e. disallowing you from accessing the resources in one application in another unless they're packed together in an ear-file) is correct. That's the way things should be, hacking around that restriction is a bad idea.

[EJB 3.0] - EntityManager auto-flush

by amashtakov

Hi folks, I'm trying to figure out how EntityManager flushes pending changes to database, but sticked with one problem - changes are automatically flushed to database without explicit merge(). Here is a project setup: 1. Entity bean | @Entity | public class User implements java.io.Serializable { | private Integer id; | private String name; | | @Id | @GeneratedValue | public Integer getId() { | return id; | } | | public void setId(Integer id) { | this.id = id; | } | public String getName() { | return name; | } | public void setName(String name) { | this.name = name; | } | } | 2. Stateless bean | @Local | public interface UserMgrLocal { | public User findById(Integer id); | ... | } | | public class UserMgr implements UserMgrLocal { | @PersistenceContext | EntityManager em; | | public User findById(Integer id) { | System.out.println("invoking findById ..."); | return em.find(User.class, id); | } | ... | } | 3. Page bean (jsf action) | ... | public String notSave() { | System.out.println("BEGIN notSave"); | UserManagerLocal userMgr = ... // obtained by JNDI lookup | User u = userMgr.findById(User.class, 1); | u.setName("kuku"); // no userMgr.save() call !!! | System.out.println("END notSave"); | return null; | } | ... | 4.

[Messaging, JMS & JBossMQ] - Re: Bug: Injected EJB objects instantiated on every MDB call

by adrian＠jboss.org

As I commented on the "bug" report. This is not JMS, this is EJB3. OFF TOPIC - use the ejb3 forum rather than respond to this post. It isn't clear to me what you are doing, but it doesn't look like a bug to me. It looks like you don't understand that ejbs are pooled and/or that multiple copies of an entity bean can exist simultanously, e.g. for optimisitic locking To have singletons you need to use some form of pessimistic locking which is usually not very performant.

In fact, a jms server doesn't even have to support two receivers on the same queue. What you are doing won't work anyway unless the messages are non-persistent. The "noLocal" is a check for is it the same connection, NOT is the same client computer. WIth an MDB (or any other receiver of persistent messages) it can reconnect (e.g. due to a failure) and the "noLocal" won't work because it is no longer the same connection. anonymous wrote : | I think that JMS was designed to sent messages to other's servers or applications, but not to it self! | | Is there a workaround ?? | Only to put a property in the message and use a selector to say I don't want messages where the property equals the one that I'm setting in my sends. But then you have to think about how you persist that value across failures. Basically a more durable version of "noLocal".

Its a JMS anti-pattern unless your connection is really a pool, e.g. java:JmsXA see the spec or the FAQ. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140052#4140052 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4140052

[JBoss jBPM] - process design advise

by tom_goring

Hi, A couple of questions: 1) Say I have a review process for a business item (awaiting review, reviewed, etc). Sometimes (say 2% of the time) the item needs to be reviewed again. I'm using the business key of the item as the business key of the process (so I can find it). If I start a new jBPM process with the same key I get problems later on due to Jbpm saying more than one process for a key. Should I reuse the same process and signal it some how to start again? Or should I some how use a different key? 2) Is there any delete functionality to clear up all ended processes? Can you point me in the direction of it. Thanks Tom View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140047#4140047 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4140047
