Hi.
I am having some serious classloader-related problems when deploying an EAR on
JBoss AS 4.2.3. The EAR contains a WAR and a lib directory at the root of the
EAR contains all the librairies. I have not defined a jboss-app.xml file and
therefore no EAR-specific loader repository, BUT I have sw
Hi all.
I have a distributed architecture which is such that I don't need cache
replication. Thus I plan to use the plain TreeCache and not PojoCache.
My question is : in non-replicated mode, do I need to call the startService()
method or do I just need to instantiate a TreeCache and that's it ?
Guys,
can you give me advice on the good way(s) to start a cache instance when on
application startup (in my case on Weblogic) ?
My idea is this :
a CacheManager singleton is instanciated by the classloader (or by the Spring
BeanFactory, whichever), the TreeCache instance -myCache- is an attrib
Are there any advantages in using PojoCache instead of TreeCache if no
replication is required ?

Hi.
I'm using TreeCache 1.4.1 with no replication. I understand that each calling
thread will start an internal transaction, even if there is no transactional
context in the client.
- Does that mean that I need to configure a TransactionManager in the cache
config file ?
- Is there any way of

Hi.
I am considering using Spring's Message Listeners with JBoss Messaging (as an
alternative to MDBs).
Can anyone tell me if it actually works ? On the JBM wiki there is a warning
about using JmsTemplates but there is no mention of the Message Listeners.

Hi.
I would like to benefit from the JCA-managed connection factory's ability to
cache connections.
In a non-clustered configuration, what is the JNDI name of that connection
factory ? Does ConnectionFactory map to it ? Should I use the same JNDI name
inside JBoss and in a standalone client ?

Hi all.
Could I please get some pointers on best practices for managing connections in
JMS publishers that send messages to JBoss Messaging ?

Thanks Clebert.
How do I make sure I am using that JCA based connection factory ?
Is its JNDI name java:/JmsXA ?
Does the JNDI name ConnectionFactory map to it ?

I did check out the Wiki AND the JBM documentation, but there are still some
open points for me.
The page that discusses the issue of JmsTemplates and connection open/close
says to use the JCA-managed connection factory with JNDI name java:/JmsXA.

I would like to know how to programmatically tell jBPM to set a timer on a
particular instance of a workflow, so that the process will resume at a
specified date.

Hi guys.
Is it possible to set a node's timer properties (e.g. duedate, repeat, etc.) by
getting them from the process instance's context variables ? Is this something
that can be done with jPDL's expression language ? If so, could you give me
pointers on the correct EL syntax for that ?
Thanks.
Hi.
I'm testing a simple process with one node and a timer at that node, and I get
the following error :

OK, problem solved, the DBSchedulerServiceFactory definition was missing in the

I am testing a very simple process containing only one node, in which a basic
timer is declared. The process is called by the doGet method of a basic servlet
:

response) throws ServletException, IOException {

It's really simple. All the timer is supposed to do is wait for one minute.
I just deploy a servlet so that I can use my browser to signal the process
instance. You have the servlet's doGet method code above. Nothing else is
needed, because it encapsulates the process definition in XML.
What I c
PROBLEM SOLVED :
Apparently jBPM cannot use a timer when the corresponding process definition
has only been instantiated in memory from an XML definition but has not been
persisted (at least in the Hibernate L1 cache if not in the DB).

Hi.
I am using an architecture where business logic and jBPM are co-located in the
same JVM and share the same classloader.
I am wondering whether I should systematically use the Command Service
interface to interact with jBPM, versus directly using the public methods
exposed by the jBPM object
I spent some time on finding out how to programmatically create and cancel
timers, so I thought it might be a good idea to share this with you.
(Note : this works with jBPM-jPDL 3.2.1 and 3.2.2).
1- Define a scheduler service in jbpm.cfg.xml :
2- Start a job executor thread (we do it via Spring
I've figured it out.

I see on the Wiki (http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWSSpecStatus)
that JBossWS require J2EE 5 for HTTP, SOAP and JAX-RPC support. I also read on

at the J2EE 1.4 level. I'm a bit puzzled.

Strangely enough, I am not getting any answer to this question. Maybe it is
stupid or badly worded.
Let me put it another way then : what is the most recent version of JBossWS
that I can use on a J2EE 1.4 compliant application server, such as JBoss 4 ?
