24 | /** | |
25 | * Callback interface to be implemented by classes that need to perform an | |
26 | * operation (such as a lookup) in a JNDI context. This callback approach | |
27 | * is valuable in simplifying error handling, which is performed by the | |
28 | * JndiTemplate class. This is a similar to JdbcTemplate's approach. | |
29 | * | |
30 | * <p>Note that there is hardly any need to implement this callback | |
31 | * interface, as JndiTemplate provides all usual JNDI operations via | |
32 | * convenience methods. | |
33 | * | |
34 | * <p>Note that this interface is an exact copy of the Spring Framework's identically named interface from | |
35 | * their 2.5.4 distribution - we didn't want to re-invent the wheel, but not require a full dependency on the | |
36 | * Spring framework, nor does Spring make available only its JNDI classes in a small jar, or we would have used that. | |
37 | * Since Shiro is also Apache 2.0 licensed, all regular licenses and conditions and authors have remained in tact. | |
