You've got the right idea.
Definitely make sure you use the WebSphere's InitialContextFactory instead of
TomEE's. Think of the `java.naming.factory.initial` like a JDBC driver.
Connecting to an Oracle DB requires an Oracle driver in TomEE, connecting to
WebSphere for EJB requires the WebSphere `java.naming.factory.initial` factory.
You also want to change the <JndiProvider id=""> to be something simple. Note
this field is not used for the JNDI name of the bean you'd like to lookup. A
simple name like "websphere" would work.
<tomee>
<JndiProvider id="websphere" type="javax.naming.InitialContext">
java.naming.provider.url =
corbaname:iiop:<hostName>:<port>/NameServiceServerRoot
java.naming.factory.initial =
<websphere-InitialContextFactory-implementation>
</JndiProvider>
</tomee>
Then in your application where you want to lookup a bean from WebSphere, you
import javax.ejb.EJB;
import javax.ejb.Singleton;
@Singleton
public class SomeTomeeBean {
@EJB(mappedName = "jndi:ext://websphere/<jndi-name-of-the-remote-bean>")
private OrangeBean orangeBean;
}
The value of `jndi-name-of-the-remote-bean` must be the JNDI name a plain Java
client would use to lookup that bean in WebSphere.
To better understand, here are the mechanics TomEE uses which are rather simple:
- When TomEE goes to inject the OrangeBean, it sees the bean is not provided
by TomEE because there is "jndi:ext:" in the mappedName
- TomEE then uses what ever text comes next in the URI
"jndi:ext:<provider-id>/" to find the `<JndiProvider>` configured in the
tomee.xml
- TomEE constructs an InitialFactory(properties) passing in *all* properties
configured between the `<JndiProvider>` and `</JndiProvider>` tags
- Now with an InitialContext instance in hand, TomEE uses the
`jndi-name-of-the-remote-bean` value to do a lookup.
- The resulting object is injected into the OrangeBean field.
Hope this helps!
