Help to understand EJB bean JNDI name

Hi Guys.

I made a small example using weblogic 10.3.6 and EJB 3.0. Define SimpleService class, define weblogic-ejb-jar.xml in order to map SimpleService class to JNDI name, pack it as EJB component in EAR file and deploy on server. Deployment is successful and I can see ejb bean with name SimpleServiceBean. After that using standalone application connect to webloigc server through InitialContext with all necessary environment attributes I try to lookup that bean. I assume that it will be available under name ejb/SimpleService but can't found it under that name and only after I was looking through a JNDI tree name I found out that it available under name SimpleService#ds/base/ejb/SimpleService. Help me to understand what is going on? How should I configure ejb bean in order that it will be available under ejb/SimpleService as it described in the official weblogic manual?

My classes and configs are:
SimpleServiceBean:
@Stateless(mappedName = "ServiceBean")
@TransactionAttribute(NEVER)
@ExcludeDefaultInterceptors
@Remote(SimpleService.class)
public class SimpleServiceBean implements SimpleService {
...
}

weblogic-ejb-jar.xml
<weblogic-ejb-jar xmlns="http://xmlns.oracle.com/weblogic/weblogic-ejb-jar"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-ejb-jar
http://xmlns.oracle.com/weblogic/weblogic-ejb-jar/1.2/weblogic-ejb-jar.xsd ">

<weblogic-enterprise-bean>
<ejb-name>ServiceBean</ejb-name>
<jndi-name>ejb/ServiceBean</jndi-name>
<enable-call-by-reference>True</enable-call-by-reference>
<stateless-session-descriptor>
<pool>
<initial-beans-in-free-pool>1</initial-beans-in-free-pool>
</pool>
</stateless-session-descriptor>
</weblogic-enterprise-bean>
</weblogic-ejb-jar>

application.xml:
<application>
<display-name>web-app-ear</display-name>
<module>
<ejb>app-ejb-1.0-SNAPSHOT.jar</ejb>
</module>
</application>

Then try to get it from standalone:
InitialContext context = new InitialContext(env);
SimpleService simpleService = (SimpleService) context.lookup("SimpleService#ds/base/ejb/SimpleService");
assert simpleService != null

UPD: ds/base/ejb it's a package where SimpleService class is situated.
