访问LDAP数据的API--JLDAP
访问LDAP数据的API--JLDAP 晴

JLDAP是由novel开发的，原是针对Novel的NDS目录设计的JAVA访问工具。NOVEL的NDS和网景（NETSCAPE）的目录是工具界最早的目录产品。JLDAP并非JNDI的服务供应者，而是同一抽象层次下的访问工具集。与JNDI-LDAP相比，JLDAP更接近于类关系数据库的访问方式。
NDS是遵守LDAP协议的并进行了扩展的类MAD产品。而NOVEL也已把JLDAP捐献给了OPENLDAP开源项目，可以世界范围内自由使用。与 JNDI相比，JLDAP无须继承DirContext才能实现添加，也无需预先生成添加的类，可以象普通数据访问那样，生成连接，然后使用::add方法添加。这样，添加的灵活性要强于JNDI。
但由于JLDAP目前是访问NDS，因此，它不具备JNDI完全面向对象存储的能力，对于高级的LDAP应用，JLDAP不是合适的选择。
