Background: I am inheriting an ancient application that utilizes EJBs. In the facet of the project it lists as a 3.0 EJB. The EJB was written while running WebSphere 6.1 where we had two jvms, one for UI/Presentation Layer and a second JVM that hosted the EJB / "data layer" which is also using JPA. We are moving to WebSphere Liberty 8.5.5.8 and when I start my application and access it, I get the following exception:
....
Caused by:
com.ibm.wsspi.injectionengine.InjectionException: CWNEN0030E: The server was unable to obtain an object instance for the java:comp/env/ejb/CHServiceBean reference. The exception message was: CWNEN1003E: The server was unable to find the com.xxx.xxx.service.CHServiceRemote binding with the com.xxx.xxx.service.CHService type for the java:comp/env/ejb/CHServiceBean reference.

Here is the code that is accessing the context object: The supplied String jndiName that is failing is: "java:comp/env/ejb/CHServiceBean"
public Object getResource(String jndiName) throws Exception {
Object obj = null;
if (obj == null) {
try {
obj = new InitialContext().lookup(jndiName);
return obj;
} catch (Exception e) {
XXXXXX.error("ServiceLocator.getResource(...) ERROR, "");
throw e;
}
}
return obj;
}
We have two packaged EAR files, Ear file A called (CHNew.ear) which contains a .war called CHNew.war that contains most of the front end logic and in the deployment assembly references the CHService.jar file. Ear file B called (CHService.ear) houses the EJB code in a war project called CHService.war. They both reside on the same application server and thus the same jvm but are obviously not packaged in the same ear file.
Ear A has the following web.xml snippet:
<ejb-ref id="EjbRef_1430884948507">
<description>
</description>
<ejb-ref-name>ejb/CHServiceBean</ejb-ref-name>

<remote>com.xxx.xxx.service.CHServiceRemoteRO</remote>

*There are binding .xmi (note not .xml) files from the past which I believe are ignored?
In the Ear App B there is an ibm-ejb-jar-bnd.xml file that contains the following stanza:
<session name="CHServiceBean">
<resource-ref name="jdbc/db" binding-name="jdbc/db"></resource-ref>
<resource-ref name="services/cache/CacheA" binding-name="services/cache/CHBluepages"></resource-ref>

Questions:
- What else do I need to do to bind this EJB?
- I have tried using the java:global namespace to reference the two EJBs (in the same EJB applcation) with the following JNDI names (which all threw JNDI naming exceptions):
- java:global/CHServiceEAR/CHService/CHServiceBean!com.xxx.xxx.service.CHSerivceBean
- java:global/CHServiceEAR/CHService/CHServiceBean
