How to initiate a specific instance?

[khalidhajsaleh]

I have a interface "A". Two different sslb beans classes "B" and "C" both implement interface "A".

How can I get either B or C using an initial context lookup? When doing an initial context, I have to use the interface A.

InitialContext ctx = new InitialContext();
A a = (A) ctx.lookup(A.class.getName());
I can not cast A to either. I would appreciate any help.

For cases like this use the @LocalBinding or @RemoteBinding annotation, it allows you to override the default jndi name

thanks, that works now!

The subclasses:

@Stateless
@LocalBinding(jndiBinding="custom/1/IDao")
public class HsqlDAO implements IDao
{}

===========

@Stateless
@LocalBinding(jndiBinding="custom/2/IDao")
public class MysqlDAO implements IDao
{}

the parent class:

@Local
public interface IDao{}

the client:

IDao bean, bean2;
String enc = "custom/2/IDao";
String enc2="custom/1/IDao";
bean = (IDao)ctx.lookup(enc);
bean2 = (IDao)ctx.lookup(enc2);
