[JBoss-user] [EJB 3.0] - Re: Accessing an EJB from a Servlet
Well, finally it works (using jboss-4.0.3SP1 and jboss-4.0.4.CR2 too)!!
Here is the code:
@Local
public interface EmployeeSessionLocal {
...
}
@Stateless ( name=Employee )
public class EmployeeSessionBean implements EmployeeSessionLocal {
@Resource ( mappedName=java:/jdbc/OracleERPDS )
private DataSource ds;
...
}
public class Controller extends HttpServlet {
public void doGet( HttpServletRequest request, HttpServletResponse response )
throws ServletException, IOException {
InitialContext context = new InitialContext();
EmployeeSessionLocal session = (EmployeeSessionLocal) context.lookup(
ysf/Employee/local );
...
}
}
Thanks to everybody!!
José Luis.

Jose, this is a lacking feature of the EJB3 spec. I have formally written the
jsr-220 group to give my opinion that jndi binding should be standardized
throughout all implementations.

[JBoss-user] [EJB 3.0] - Re: Accessing an EJB from a Servlet
My application is packaged using an EAR (ysf.ear), with a JAR (ysf.jar) and a
WAR (ysf.war), and the JAR being deployed first.
The jmx-console doesn't show me the JNDI service, the only place where I found
references to my application is here:
jboss.j2ee
* ear=ysf.ear,jar=ysf.jar,name=Employee,service=EJB3
* module=ysf.jar,service=EJB3
* service=ClientDeployer
* service=EARDeployer
* service=EARDeployment,url='ysf.ear'
This is the log shown in the console window when the application is deployed:
08:55:07,441 INFO [EARDeployer] Init J2EE application:
file:/J:/jboss-4.0.3SP1/server/all/deploy/ysf.ear
08:55:07,882 INFO [Ejb3AnnotationHandler] found EJB3: ejbName=Employee,
class=es.dbs.ysf.employee.EmployeeSessionBean, type=STATELESS
08:55:07,892 INFO [Ejb3Deployment] EJB3 deployment time took: 90
08:55:07,932 INFO [JmxKernelAbstraction] installing MBean:
jboss.j2ee:service=EJB3,ear=ysf.ear,jar=ysf.jar,name=Employee with dependencies:
08:55:08,533 INFO [EJB3Deployer] Deployed:

08:55:09,705 INFO [EARDeployer] Started J2EE application:
file:/J:/jboss-4.0.3SP1/server/all/deploy/ysf.ear
And this is part of my source code:
EmployeeSessionLocal.java
@Local
public interface EmployeeSessionLocal
{ ... }
EmployeeSessionBean.java
@Stateless(name=Employee)
public class EmployeeSessionBean implements EmployeeSessionLocal
{ ... }
Controller.java
public class Controller extends HttpServlet {
public void doGet( ... ) throws ServletException, IOException
{
InitialContext context = new InitialContext();
EmployeeSessionLocal session = (EmployeeSessionLocal)
context.lookup( Employee );
...
}
}
Any idea?
Thanks!!
José Luis.

[JBoss-user] [EJB 3.0] - Re: Accessing an EJB from a Servlet
I haven't had any luck using the class.getName() lookup either. The only way I got it to work is using sm = (SiteManager)ic.lookup(SiteManagerImpl/local); - which I can see in the Global JNDI Namespace. (ic being my InitialContext variable, SiteManager being the stateless session bean interface, and SiteManagerImpl being the implementation.) In the EJB3Trail sample app, this is how they are doing it in the JSPs.

More than likely your lookup is wrong or your EJB3 is not bound properly? Just out of shear curiousity, where are your EJB3's packaged? You can't put them in your WAR as classes because the EJB3 deployer needs to see them. You should have an EAR with a JAR and a WAR module defined or separate WAR and JAR files deployed (JAR being deployed first).
