[Design of EJB 3.0] - Default JNDI naming scheme in EJB3.0 and possible conflicts
by jaikiran
The current default jndi binding scheme http://www.jboss.org/community/docs/DOC-9569 doesn't take into account the module name of the EJB. For example, if i have an ear named MyApp.ear containing 2 jar files First.jar and Second.jar and both containing a bean implementation AppManagerBean:
First.jar:
| package org.myapp.first.impl;
|
| @Stateless
| @Remote (org.myapp.first.AppManager.class)
| public class AppManagerBean implements org.myapp.first.AppManager {
|
| public String getVersion() {
| return "1.0";
| }
|
|
| }
|
Second.jar
package org.myapp.second.impl;
|
|
| @Stateless
| @Remote (org.myapp.second.AppManager.class)
| public class AppManagerBean implements org.myapp.second.AppManager {
| public String getVersion() {
| return "2.0";
| }
|
| }
|
Then as per the default JNDI naming scheme both these beans will resolve to MyApp/AppManagerBean/remote. From what i see in the current version, only one bean (the first one) gets bound to the JNDI and the other bean does not get bound:
+- MyApp (class: org.jnp.interfaces.NamingContext)
| | +- AppManagerBean (class: org.jnp.interfaces.NamingContext)
| | | +- remote (class: Proxy for: org.myapp.first.AppManager)
| | | +- remote-org.myapp.first.AppManager (class: Proxy for: org.myapp.first.AppManager)
|
Shouldn't we be logging a WARN message in the logs letting the user know of this conflict?
P.S: EJB3.1 spec seems to address this with the global jndi name scheme which results in a unique jndi name in these cases.

[Design of JBoss jBPM] - Re: meeting context
by alex.guizar＠jboss.com
Some topics I'd like to discuss:
# Start process instances at predefined time (related to Quartz and BPMN)
# Enterprise Application Integration
* eMail: send and receive - e.g. task completion via email in red hat oracle apps
* JMS: transfer data back and forth between process variables and message properties/body
* ESB: jboss and other providers - position jBPM as the de facto "scripting" language for ESBs
* Web services: borrow and improve concepts from BPEL
* Databases: facilities for accessing external databases
* Flat files: just mentioned for completeness
# Pluggable transaction management
* Internal
* CMT
* Seam/Spring
# Rules
* Rules in event actions: have rules evaluated as process events fire, or variables change
* Rule-based decision node
* Rule-based task assignment
I already added these topics to the team meeting page.
