Spring LDAP - Creation of LdapTemplate in standalone java program - Using Spring LDAP as CDI Resource

Question

I am trying to construct a LdapTemplate object of using spring data.

 public class LDAPTemplate {

        public static void main(String[] args) {
            LdapContextSource lcs = new LdapContextSource();
            lcs.setUrl("ldap://localhost:389/");
            lcs.setUserDn("cn=Manager, dc=example, dc=com");
            lcs.setPassword("secret1");
            lcs.setDirObjectFactory(DefaultDirObjectFactory.class);
            LdapTemplate ldap = new LdapTemplate(lcs);
            ldap.lookup("cn=aaa");

        }

    }

I wanted to know is that the right way to instantiate ldap template object. Because when I perform a lookup, it throws NPE.

I am trying to use LDAP Spring in CDI context without using spring at all. If you have pointers on that would be nice. Does Spring LDAP is dependent on spring?

Answer 1

LdapContextSource is InitializingBean so you need to call afterPropertiesSet...

And the JavaDoc:

When using implementations of this class outside of a Spring Context it is necessary to call afterPropertiesSet() when all properties are set, in order to finish up initialization.

Correct Code

public class LDAPTemplate {
    public static void main(String[] args) {
        LdapContextSource lcs = new LdapContextSource();
        lcs.setUrl("ldap://localhost:389/");
        lcs.setUserDn("cn=Manager, dc=example, dc=com");
        lcs.setPassword("secret1");
        lcs.setDirObjectFactory(DefaultDirObjectFactory.class);
        lcs.afterPropertiesSet();
        LdapTemplate ldap = new LdapTemplate(lcs);
        ldap.lookup("cn=aaa");

    }
}
