I tried different approaches with
org.wso2.carbon.user.api.UserStoreManager OSGi
service, however I couldn't overcome the NullPointerException. I think one
must initialize the UserStoreManager service before using it, but couldn't
find an initializing method.
*Solution:*
Instead of using UserStoreManager OSGi service, I used
org.wso2.carbon.user.core.service.RealmService OSGi service. Using the
RealmService you can get TenantUserRealm object for a given tenant ID. From
that you can get an UserStoreManager object. This object (usManager) has
all functionality of UserStoreManager OSGi service. Refer following sample
code.
var carbon = require('carbon');
var store = require('store');
var server = store.server;
function test(role){
var realmService =
carbon.server.osgiService('org.wso2.carbon.user.core.service.RealmService');
var tenantId = server.current(session).tenantId;
var usManager =
realmService.getTenantUserRealm(tenantId).getUserStoreManager();
return usManager.getUserListOfRole(role);
}
Thanks & regards.
