public interface JndiCallback<T>
Note that there is hardly any need to implement this callback interface, as JndiTemplate provides all usual JNDI operations via convenience methods.
T doInContext(Context ctx) throws NamingException
Implementations don't need to worry about error handling or cleanup, as the JndiTemplate class will handle this.
ctx- the current JNDI context
NamingException- if thrown by JNDI methods
