Is the SimpleNotEjbType available in JNDI? If yes, then you can use the mappedName attribute of the @Resource to point to the jndi name of that resource and have it injected:

@Resource (mappedName="jndiname")
private SimpleNotEjbType type;

No, the EJB container will not inject the resources into that POJO class.
