Caching JNDI Lookup

Recommended way of invoking a EJB local interface method is to perform a lookup:

<code>
Context ic = new IntialContext(); 
ic.lookup(objectJndiName);
</code>

However, I browse the complete JNDI tree at the start of application and at the end I am able to create a map of all objects with:

<code> 
   Map <String,Object> 
</code>

with key ObjectName and object of required Interface Implementation. I search the object with key and invoke the required method on interface like this: 

method.invoke(bean, args);

Is this method ok? or should I perform lookup for the required ejb everytime?

Solution

  • JNDI lookups is not the recommended way for instantiating references of Local Interfaces of Stateless beans, as from EE5 and above. Simply injecting the bean with @EJB annotation or CDI's @Inject will do the job fine.
