首先准备openLDAP ， window 版或linux版都可，
重点：
You need to add include schema/java.schema to your OpenLDAP configuration
否则利用JNDI LDAP provider 无法绑定对象。
1. 绑定对象person 到cn=user2,o=tt,c=cn
import java.io.Serializable;
import javax.naming.NamingException;
import javax.naming.Reference;
import javax.naming.Referenceable;
import javax.naming.directory.DirContext;
public class person implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
绑定后可以看到LDAP的内容增加了一下内容
javaSerializedData 等信息。

并且可以通过LDAP的JNDI来进行进程间通信
