--------------------------------------------------------------
Hello,
We are using JBoss 5.1.0 GA, jdk 1.5_22, Solaris 10.
We have implemented a wsdl-to-java EJB3.0 web-service endpoint and have generated the client artifacts using wsconsume. These artifacts are included in a client project - a war that includes a Servlet that calls the endpoint using the generated WS client.
The web-service project is deployed as an ejb jar, which is included into an .ear.
The war project (the ws client) is deployed in the same JBoss configuration as the .ear.
For testing, we implemented an HttpClient that calls the Servlet, which calls the EJB3.0 endpoint.
Everything is working well, until performing testing with 100 threads, each sending a request 50 times.
We first created a new WS Client instance for every request, but then we decided to create a pool of these instances to gain performance.
We can not reuse the same instance because the WS Client is not thread-safe.
For the pool, we used http://commons.apache.org/pool/ http://commons.apache.org/pool/.
Here is the code that creates a new instance:
public Object makeObject() {
OurEnpointWSService service = new OurEnpointWSService();
BindingProvider bp = (BindingProvider) service;
bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, url);
OurEnpoint port = service.getOurEndpointWSPort();
return port;
}
At some point, after running the tests 3-4 times, we receive a lot of errors:
2010-09-29 14:44:04,980 ERROR [org.jboss.ws.core.CommonClient] (http-0.0.0.0-8080-305) Exception caught while (preparing for) performing the invocation:

[Beginner's Corner] - JBoss : persistence and EntityManager injection

Hi,
I'm starting a small testing project from scratch, but I'm getting some trouble configuring JPA persistence ... I'll post some code fragments and hope someone can enlight me on the issue.
I have an EAR, my-ear, and inside there is a single WAR, my-war. All definitions should be placed correctly, since I can make it to pick all settings, even those defined in "persistence.xml".
my-war structure
C:.

<persistence-unit name="punit">
<jta-data-source>java:jdbc/MyDB</jta-data-source>
</persistence-unit>
</persistence>
My Java code has the following class:
SimpleMessage.java
package com.my.package;
import javax.persistence.PersistenceContext;
public class SimpleMessage {
@PersistenceContext
private EntityManager em;
@PersistenceUnit(name="punit")
private EntityManagerFactory emf;
public void something() {
if( em!=null ) {
System.out.println("EntityManager Available!");
} else {
System.out.println("EntityManager is NULL!");
}
if( emf!=null ) {
System.out.println("EntityManagerFactory Available!");
} else {
System.out.println("EntityManagerFactory is NULL!");
}
}
}
I intend to test just this ... a simple basic class where I inject the manager instance. The class is not an EJB class, just an basic injected class.
When deploying, I get the following result:
2010-10-13 14:09:55,197 INFO [org.jboss.web.tomcat.service.deployers.TomcatDeployment] (HDScanner) deploy, ctxPath=/my-war

However, if in "persistence.xml" I instead define the datasource reference as "java:ds/MyDB" (datasource name definition on JBoss), I obtain the following result:

So my questions are:
*1#* After invoking "SimpleMessage.something();" (using the second option "java:ds/MyDB" in "persistence.xml") I receive the following output:
EntityManager is NULL!
EntityManagerFactory is NULL!
So no injection happened ... shouldn't it occur? what happened?
*2#* I was assuming that "web.xml" defines the JNDI to be used inside my webapp, then "jboss-web.xml" would map that name into the internall JNDI defined in JBoss.
In this case for JBoss usage, if changing to IBM WebSphere I would use another mapping config file.
BUT ... I was also assuming that "persistence.xml" would define the JNDI that is defined in "web.xml" ... and not the one defined in application server level ... so I would get an abstraction from whichever server I'll deploy my project into.
Shouldn't this be working like that? What am I doing wrong?
Any help would be appreciated ... I really need to understand and put this to work ...
Thanks.

Marlboro mark - the most known cigarette mark world wide. In the beginning it was showed in 1847 at the market of London but shortly moved in the USA. 1924, Philip Morris launched Marlboro brand as a lady’s http://www.cigarettesbox.com/ cigarettes online with the slogan: "Mild as May". Philip Morris (PM) focused on female public a number of advertisements in 1926. They featured fashionable women, who posed in velveteen settings. During the Second World War, the mark faltered and had to be removed from the cigarette market. After this failure Philip Morris focused its advertisement campaign to male.

--------------------------------------------------------------
we observed some issue in our Application while migrating Jboss 4.0.4 to Jboss-EAP-5.0.1. We are using Containter-Managed Persistence in my project and causing issues when performing Asynchronous transactions (JMS).
Before sending message to JMS Queue, my application making an entry in the database. After persisting the record, It sends the Primary Key along with the JMS message.
In message Driven bean we trying to find the same record using the primary key that we received throught the jms message and failing intermittently. As we are making bulk operation we are able to find the record for some transactions and for some tasks the operation is getting failed.
Jboss CMP not persisting the data before sending the message to queue and causing the issue. The code works fine with jboss 4.0.4 but failing with jboss-eap-5.0.1. please give ur suggestions or do i need to do any changes more. Thanks in Advance.

[jBPM] - Questions on JBPM 4.4.
by Abdelilah Essiari

"Questions on JBPM 4.4."

--------------------------------------------------------------
I am evaluating JBPM 4.4 (JPDL) for my project and I have ran into a couple of issues:
One is that a mix of exclusive continuations are asynchronous continuations does not quite work.
Upon a close look at AcquireJobsCmd.java, it becomes aparrent:
a) more than one exclusive job can execute in different transactions.
b) an exclusive job concurrently with an asynchrouns job is running.
This defeats my understanding of what exclusive means. I have tentatively modified AcquireJobsCmd.java by ensuring
that a and b do not happen. This important in my case as I have an assign statement that needs to update a process
variable inside a forEach with asynchronous java continuations as shown below. This only works after I made my changes.
<variable history="false" name="GlobalMap" type="serializable">
<map>
</map>
</variable>
<foreach g="160,261,48,48" in="#{dataSources}" name="foreach" var="dataSource">
<transition to="do lookup"/>
</foreach>
<java continue="async" class="test.JavaService" g="327,259,98,50" method="lookup" name="do lookup" var="returnVar">
<arg>
<object expr="#{dataSource}"/>
</arg>
<arg>
<string value="kw"/>
</arg>
<transition continue="exclusive" to="copy" />
java>
<assign from-expr="#{returnVar}" name="copy" to-expr="#{GlobalMap[dataSource]}">
<transition to="join"/>
</assign>
<join g="567,259,80,40" multiplicity="2" name="join">
<transition to="do materialize"/>
</join>
...
The other question is that +returnVar+ is actually mapped to the parent execution. It should map to the forked execution as is the variable +dataSource+. Shouldn't it?
In any case the tentative fix for this was easy. Just changed a one line in JavaActivity.java.
if (variableName!=null) {
// execution.setVariable(variableName, returnValue);
execution.createVariable(variableName, returnValue);
}
Hope to hear from someone. Thanks in advance.
