Okay, each component [application, web context, ejb, ....] you deply
will have its own Context. It will be located at "java:/comp/env".
Now if you are looking for something that is bound to "java:/comp/env"
from with a servlet you have to put it there. You would put it there
thru ejb-ref in your web.xml
If you used "java:/comp/env" from within an EJB then you would need
references in the ejb-jar.xml
That is all true about local context. JBoss however has a global context.
Where it binds your objects. I am not sure exactly what convention is
when you do not provide those three optional xmls that I was talking
about in my earlier post, but those are basically needed to provide
connections.
So jboss.xml will bind your ejbs into the global context so that other
components [apps] can reference it (in their local "java:/comp/env";
jbossweb.xml will do similar job for your web app.
Okay just to give you some example, suppose we have a bean Facade:
ejb-jar.xml
<session >
<description><![CDATA[Facade Bean]]></description>
<ejb-name>Facade</ejb-name>
<home>edu.columbia.law.tas.ejb.FacadeHome</home>
<remote>edu.columbia.law.tas.ejb.Facade</remote>
<ejb-class>edu.columbia.law.tas.ejb.FacadeEJB</ejb-class>
<session-type>Stateful</session-type>
<transaction-type>Container</transaction-type>
</session>
jboss.xml
<session>
<ejb-name>Facade</ejb-name>
<!-- note this is your global name for FacadeHome
watch it referenced in jbossweb.xml -->
<jndi-name>ejb/tas/FacadeHome</jndi-name>
</session>
web.xml
<!-- this is the declaration that will bind FacadeHome into the
local context of your web application so that you can do
InitialContext initialContext = new InitialContext();
try {
java.lang.Object objRef =
initialContext.lookup("java:/comp/env/ejb/Facade");
return (edu.columbia.law.tas.ejb.FacadeHome)
PortableRemoteObject.narrow(
objRef,
edu.columbia.law.tas.ejb.FacadeHome.class);
} finally {
initialContext.close();
}
-->
<ejb-ref>
<ejb-ref-name>ejb/Facade</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>edu.columbia.law.tas.ejb.FacadeHome</home>
<remote>edu.columbia.law.tas.ejb.Facade</remote>
<ejb-link>Facade</ejb-link>
</ejb-ref>
jbossweb.xml
<!-- finally this is where you connect your ejb/Facade to
the global home -->
<ejb-ref>
<ejb-ref-name>ejb/Facade</ejb-ref-name> <!-- local name fo it -->
<jndi-name>ejb/tas/FacadeHome</jndi-name> <!-- global context look at
jboss.xml -->
</ejb-ref>
That is about it. The only thing that I can not find in jmx-console
is how do I see the env context of my web context it has to have
one, but it might be Jetty hidden. So I have not found a way to browse it.
