EJB Deployment

[gtigti]

Hi,

I'm new to jboss and I have to deploy a J2EE application.
The WebModule, the JavaModule and the DataSource (Oracle) are working fine, but not the EJBModule

I have this error :

javax.naming.NameNotFoundException: ejb not bound

I red about jboss.xml but I dunno where to put it, what do I have to put in it or if it's necessary to write it or not.

Note that from the jmx-xonsole, I have the following :

JMX MBean Operation Result
Operation list()

java:comp namespace of the OPCAISSE bean:
+- env (class: org.jnp.interfaces.NamingContext)


These two lines are displayed for each of my Java beans, so the EJB Module was correctly deployed I guess.

Can someone help me with this please ? ...

Thx in advance

[gtigti]

No one have had problems with EJB deployment ?

Please, it's very urgent ......

[gtigti]

I think I have to write this fragment for each session bean or entity bean I have :


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


but I don't know what values I have to put in these tags, suppose I have an entity bean with name OPCAISSE in com.gti.iagence.ejb.opcaisse.entity package

So the fragment will look like this ?


<ejb-name>OPCAISSE</ejb-name>
<jndi-name>com/gti/iagence/ejb/opcaisse/entity/OPCAISSE</jndi-name>
<local-jndi-name>OPCAISSELocal</local-jndi-name>


please help ....

I don't know whether you are trying to deploy a session bean or entitry bean, but here is an example of both xml descriptors that works.

Fragment from ejb-jar.xml

 <session>
 <display-name>Menu Option Use Case Session Bean</display-name>
 <ejb-name>milton/appmenu/optionmaint</ejb-name>
 <home>org.milton.services.applicationmenu.OptionMaintHome</home>
 <remote>org.milton.services.applicationmenu.OptionMaintRemote</remote>
 <ejb-class>org.milton.services.applicationmenu.OptionMaintBean</ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 <ejb-ref>
 <ejb-ref-name>ejb/milton/appmenu/menuoption</ejb-ref-name>
 <ejb-ref-type>Entity</ejb-ref-type>
 <home>org.milton.services.applicationmenu.MenuOptionHome</home>
 <remote>org.milton.services.applicationmenu.MenuOptionRemote</remote>
 <ejb-link>milton/appmenu/menuoption</ejb-link>
 </ejb-ref>
 </session>
 <entity>
 <description>Menu Option Entity Bean</description>
 <display-name>Menu Option EJB</display-name>
 <ejb-name>milton/appmenu/menuoption</ejb-name>
 <home>org.milton.services.applicationmenu.MenuOptionHome</home>
 <remote>org.milton.services.applicationmenu.MenuOptionRemote</remote>
 <ejb-class>org.milton.services.applicationmenu.MenuOptionBean</ejb-class>
 <persistence-type>Bean</persistence-type>
 <prim-key-class>java.lang.String</prim-key-class>
 <reentrant>False</reentrant>
 <primkey-field>shortCode</primkey-field>
 <resource-ref>
 <res-ref-name>jdbc/MiltonDS</res-ref-name>
 <res-type>javax.sql.DataSource</res-type>
 <res-auth>Container</res-auth>
 </resource-ref>
 </entity>


Entire jboss.xml

<?xml version="1.0" encoding="Cp1252"?>
<!DOCTYPE jboss PUBLIC "-/JBoss//DTD JBOSS 3.0//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd">


<!-- Define security domain for the Milton application. -->
<jboss>
 <security-domain>java:/jaas/Milton</security-domain>
 <unauthenticated-principal>guest</unauthenticated-principal>
 <enforce-ejb-restrictions>false</enforce-ejb-restrictions>
 <resource-managers>
 <resource-manager>
 <res-name>jdbc/MiltonDS</res-name>
 <res-jndi-name>java:/DefaultDS</res-jndi-name>
 </resource-manager>
 </resource-managers>
</jboss>

This gives a full definition of a session bean, which references an entity bean.

The entity bean in turn references a datasource defined in jboss.xml.

You can use a reference in jboss.xml of form :-

 <entity>
 <ejb-name>milton/appmenu/menuoption</ejb-name>
 <jndi-name>another/jndi/name</jndi-name>
 </entity>

but you only need this if you can't map your EJB names one-to-one with the JNDI names.

I'm trying to deploy session beans and entity beans, but I dunno if I will need to reference them all in a jboss.xml file, my DS is working fine without that file.

So ca, I deploy without using jboss.xml ?

my ejb-jar.xml file looks like this :


<?xml version="1.0" encoding="UTF-8"?>

You need to add all your beans to a jboss.xml file that maps EJB names to JNDI names. This is explained in the previous messages.

Furthermore I think you are looking up "ejb" instead of the actual bean you want, which would be something like "OPCAISSESB".
