JNDI lookup issue - EJB not bound

[gurmat]

Hi All,

I am new to Jboss...We are migrating from WAS4 to JBoss4.3 and are running into issues for EJB.

For all the EJBs, it is giving below exception:

2010-12-17 09:52:29,008 ERROR [STDERR] javax.naming.NameNotFoundException: ejb not bound

Below is the JNDI look up code

InitialContext ic =

new InitialContext();

VendorOSTrackingHome home = (VendorOSTrackingHome) ic.lookup(

"ejb/BulkLoaderApp/VendorOsTracking");

I am really stuck on this...Can anyone please help us out in this??

What EJB version do you use?

Do you see that the EJB application is correct deployed and you see it in the jmx-console?

You can use the jmx console to browse the jndi tree so you can verify that the EJB is bound correcly: http://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/4/html/Additional_Naming_MBeans-The_org.jboss.naming.JNDIView_MBean.html

Thanks Anders / Wolf-Dieter for your response!!

The EJB version we are using is 1.0.

One thing I noted in JMX console in JMX MBean Operation Result list() is that I am not finding reference of those EJBs under EJB module and Global JNDI name...

No finding any reference of those EJBs under this

Global JNDIname

I am not finding any reference of the EJBs under this

I think it is not deployed correctly..not sure what I am missing out...

Thanks,

I have similar issue but I am using JBoss 6 CR1 with EJB 2.1

I tried to look it up through JMX console but I couldn't find the jndi name of the bean. However in the deployment log it said

09:19:03,062 INFO  [EjbDeployer] installing bean: ejb/myapp.jar#EBMyBean,uid1165664
09:19:03,062 INFO  [EjbDeployer]   with dependencies:
09:19:03,062 INFO  [EjbDeployer]   and supplies:
09:19:03,062 INFO  [EjbDeployer]     jndi:EBMyBean
09:19:03,062 INFO  [EjbDeployer]     jndi:local/EBMyBean@11368117

so I am confused.

[newguy2010]

Just to post the progress of solving the JNDI lookup issues I am facing.

Previously I only used a ejb-jar.xml to specify ejb names but I didn't use a jboss.xml to specify jndi names. In JBoss 3.2.5, which is the previous JBoss version I have been using, a default JNDI name was given to the ejb object if no jndi name is specified. For some reason JBoss is able to look it up without a jboss.xml file and wouldn't put something like local/EBMyBean@11368117 as the jndi name.

When I use JBoss 6 this doesn't work. I have to put a jboss.xml to specify jndi names. So I just put ejb/EBMyBean as the jndi name and JBoss is able to look it up as ejb/EBMyBean. I can also change the name to whatever I like but I guess the default jndi name always contain some number in it so it is hard to know what the default jndi name is.

After changing the jndi names in a jboss.xml file I no longer see this EJB not bound error.

My jboss.xml is something like this:

<jboss>

     <entity>
        <ejb-name>EBMyBean</ejb-name>
        <local-jndi-name>ejb/EBMyBean</local-jndi-name>
    </entity>

</jboss>
