[EJB/JBoss] - Re: PostConstruct loadClass fails when porting to JBoss 5
by jcstaff2
Andrew,
* Thanks for the specifics on why the handling of deployment descriptor whitespace changed. Yes, with a more-compliant application server schema, "I was adding the extra whitespace" - point taken.
* We are all set on the reading of a read-only resource.
* Tom Marrs wrote about 3 classloaders; system, current, and thread. He ruled out use of the first 2 for known reasons and then stated why you should use the later. This is what my code is doing; access the classloader through the current Thread.
anonymous wrote :
| You gain access to the current Thread Context ClassLoader by calling Thread.currentThread().getContextClassLoader(). ... Use the Thread Context Class Loader for the following reasons:
|
* On the use of the reflection API and ClassLoader, the listed restrictions state that what I wanted to do with the ClassLoader was legal
anonymous wrote :
| Contrary to common belief, most of the Java Reflection API can be used from EJB components. For example, loadClass() and invoke() can both be used by enterprise beans. Only certain reflection methods are forbidden.

Thanks for taking the time on this.

[JBoss Messaging] - Re: JBM replication needed?
by FrankTheTank
Slony only does master-slave replication.
Setup:
DBs A (master) and B (slave)
AppServer cluster with both A and B in their datasource list.
So in the normal case all cluster nodes connects to A (alas a shared database).
Slony externally replicates the database from A to B.
Now if A fails, the AppServers switch to B.
(the replication terminates in the background).
Question is, do I even need to replicate the JBM database to the slave?
As I have no idea how JBM persists it's data, I am unsure of this.
F.i. do the pre-failover messages still exist after failover if they were not replicated?
i.e. these messages are lost and would cause the subscribers to miss them.
If I do, then I wonder if it is possible to tell JBM to persist it's tables in a specific schema of the database in order to simplify the replication.

[JBoss jBPM] - [JBPM4 Error]Getting error while 2 tasks are created on same
by sushantgupta402
I have a process as below
(Start -> Task-1(Assign it to User1) -> Task-2(Assign it to User2) -> Task-3 (Assign to User 3) -> End.
I started the process instance and then signalled the it from Start to Task-1 a task is generated for User1 (checked in the database). Now I signalled the process again and the process got moved ahead to Task-2 and a new task is created for User2 now when I signalled the process instance again got the error org.hibernate.NonUniqueResultException: query did not return a unique result: 2. Below is the stack trace. Please let me know if this is a bug and when can we expect this to be fixed.

[JCA/JBoss] - JBoss ESB with JBoss Tools
by anushree123
Hi,
I have been working with Open ESB for quite some time and have just started exploring JBoss ESB.
I downloaded JBoss tools plugins and tried out a simple project: JBossESB Service capable of processing JMS/ESB messages
I am getting the following exception while server startup:

[JBoss jBPM] - Jbpm, Hibernate, JPA issues
by jbpm_user369
Hello,
we are building a project using JPA for persistence and Spring for bean management. We're using Jbpm for handling the business workflow. The jbpm tables used will share the same db with the application, and the jbpm context will share the JPA session of the application.
The jbpm version used is 3.2.3. Since the jbpm tables are mapped using Hibernate, we have entered the following mapping-file declarations inside the project persistence.xml:
