I assume from your example that the bean in question exposes a Remote interface. In that case, it's easy to do this by configuring a unique global <jndi-name> for each ejb in a META-INF/sun-ejb-jar.xml file. E.g. :
<sun-ejb-jar>
<enterprise-beans>
<ejb>
<ejb-name>mySLSB</ejb-name>
<jndi-name>mySLSB/1</jndi-name>
</ejb>
</enterprise-beans>
</sun-ejb-jar>
You can find more about JNDI names in our EJB FAQ :
