How can I get all user names registered in JDBC or LDAP real

Posted by Admin on 29-Feb-2012 01:08

We are creating a limited demonstration project that will provide a feature to dynamically select human performer on portal. We would like to have a combobox populated with user names selected dynamically from JDBCRealm or LDAPRealm.

I attemped to use the following code to extract an array of user names and print the first one:

String realmName = "JDBCRealm";
        com.tdiinc.userManager.Realm realm = UserManager.getRealm(realmName);
        java.lang.String[] userNames = realm.getUserNames();

In this code UserManager.getRealm(realmName) method returns <null>.

Has anyone, by chance, implemented anything similar to what I'm trying to achieve?

Thank you in advance.

Hi Viatcheslav,

Below code will return all the JDBC and LDAP users.

JDBCRealm jdbcrm=(JDBCRealm) UserManager.getDefaultRealm();

//LDAPRealmjdbcrm=(LDAPRealm) UserManager.getDefaultRealm();

java.lang.String[] userNames = jdbcrm.getUserNames();

Thanks a lot for your solution! I checked it and it works as required. Following your idea I created my own that relies on polymorphism of getUserNames() defined in Realm interface to abstract the code from realm type:

import com.tdiinc.userManager.Realm;
import com.tdiinc.userManager.UserManager;


public void execute() {
        Realm realm = UserManager.getDefaultRealm();
        String[] users = realm.getUserNames();
        this.lstPerformers  = new Vector();
        for (int i = 0; i

Another way one may find useful is to create JDBCRealm/LDAPRealm object with default constructors:

JDBCRealm realm = new JDBCRealm();

// LDAPRealm realm = new LDAPRealm();

Thanks again for the correct answer!
