Package org.springframework.jndi
Interface JndiCallback<T>
public interface JndiCallback<T>
Callback interface to be implemented by classes that need to perform an operation (such as a lookup) in a JNDI context. This callback approach is valuable in simplifying error handling, which is performed by the JndiTemplate class. This is a similar to JdbcTemplate's approach.Note that there is hardly any need to implement this callback interface, as JndiTemplate provides all usual JNDI operations via convenience methods.
