Ok. This is good information for the when I actually package the EAR
and deploy to the server. However, right now, I am completely outside a
Geronimo container. How would I get this remote lookup to work? Once
again, the method that I am using now used to work with Geronimo 2.x

If you are doing the JNDI lookup from separate client EAR. You'll
have to provide a geornimo application deployment plan so that the
client can get the ejb remote interface from the OSGi framework
instead of from the remote interface packaged in the client ear.
That means, you don't have to provide a remote interface class in
your ejb client ear. The remote interface will be provided by the
copy that the EJB provider registered in OSGi framework after you add
a "import" clause in the geronimo application deployment plan.
<application
xmlns="http://geronimo.apache.org/xml/ns/j2ee/application-1.2";>
<dep:environment
xmlns:dep="http://geronimo.apache.org/xml/ns/deployment-1.2";>
<dep:moduleId>
<dep:groupId>default</dep:groupId>
<dep:artifactId>your_seperate_EAR</dep:artifactId>
<dep:version>1</dep:version>
<dep:type>car</dep:type>
</dep:moduleId>
<dep:dependencies>
</dep:dependencies>
<dep:import-package>*your.remote.ejb.interface.package*</dep:import-package>
<dep:hidden-classes/>
<dep:non-overridable-classes/>
</dep:environment>
</application>
This is a limitation in Geronimo 3.0 after changing the OSGi
framework. Hope this helps.

First of all, thank you for your response. The EAR has a
structure of:
<ear-archive>
-lib
-<various assemblies
- remote interface.jar
- META-INF
- application.xml
- geronimo-application.xml
- business-ejb.jar
Eventually, there will be two EAR archives in the Geronimo
server. Currently, there is only one that has been deployed to
the Geronimo server. I am testing the second EJB project using
JUnit so currently it is acting as a stand alone client. I am
doing/will be doing the lookup using a separate EAR deployed to
the Geronimo server.
The JNDI lookup is currently in a regular AppClient that is using
JUnit to run tests.
The remote interface is included in the classpath of the
AppClient. Also, the following entry is included in the maven
dependancy:
<dependency>
<groupId>org.apache.openejb</groupId>
<artifactId>openejb-client</artifactId>
<version>4.0.0</version>
<scope>provided</scope>
</dependency>
Currently, I have an EAR archive that has been deployed to the
server.

I'd like to know the structure of your EAR. Are you doing the
JNDI searching in the same EAR or in separate EAR ?
What's module the JNDI lookup is in ? WAR, or AppClient.
I remember for remote interface based JNDI EJB lookup in G3.
you'll have to import the remote interface in the client module
to make sure the same interface could be loaded within OSGi
framework in client side.

2.x, this worked perfectly. Now I am having issues. First,
when I deploy the ear, this is the JNDI entries that are
created.

I try to use this code to access the ejb's.
InitialContext context;
// Configure Initial context
try {
this.m_emailManager =
(IEmailManagerRemote)context.lookup("EmailManagerRemote");
// Other statements
I get this error upon lookup:

please tell me what I am doing wrong because this technique
worked in previous versions of Geronimo.
