Interface ContextCallback


public interface ContextCallback

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 approach to that used by the JdbcTemplate class.
