I'm developing a web app for AppM and I want to do some user management
tasks.
- retrieving all users for a given role
- retrieving claims of a given user
To accomplish above tasks, I want to call getUserListOfRole() method &
getUserClaimValues() method in the org.wso2.carbon.user.api.UserStoreManager
OSGi service. I wrote my Jaggery code as following based on [1] & [2].
routeManager.register('GET', 'publisher',
'/publisher/api/provisioning/users/{role}', function (context) {
log.info("### in API call");
var role = context.params.role;
var carbon = require('carbon');
var userService =
carbon.server.osgiService('org.wso2.carbon.user.api.UserStoreManager');
log.info("### acquired OSGi service");
*#30* var usrs = userService.getUserListOfRole(role);
print(usrs);
});
Above code gives me a NullPointerException.
