My code is :
List<Status> list = new ArrayList<Status>();
User user;
Twitter twitter = new Twitter();
list = twitter.search(string);
for(int i=0; i<list.size();i++){
user=list.get(i).getUser();
System.out.print(i+1);
System.out.println(list.get(i));
System.out.println(list.get(i).getId());
System.out.println(list.get(i).getUser());
System.out.println(user.getId());
System.out.println(user.getCreatedAt());
System.out.println(user.getLocation());
System.out.println(user.getFavoritesCount());
}
The problem is that good print the status, id of status and user, but user features how user id, location, etc, prints all as null. What I can do to take the features????
Thanks for response
According to the JTwitter API Docs, calling the default constructor creates a new instance without a user. You need to authenticate with Twitter using Twitter.IHttpClient (which depends on Signpost) to get user data.
The Twitter search method is unusual in that it only returns a small part of the User information. This is a limitation from Twitter & there's nothing you can do about that.
Fields such as location will be blank.
You always get the screen-name, and this can be used to fetch the extra info via the show() method. E.g.
Twitter twitter;
List<String> userNames; // make this list from user.screenName
List<User> fullUserInfo = twitter.users().show(userNames)
If you have an up-to-date copy of JTwitter (http://www.winterwell.com/software/jtwitter.php) it is all in the javadoc.
NB: Other methods sometimes return missing fields in User, if Twitter is experiencing heavy load.

I need to assign roles to my Liferay's users when they log in the application.
I have implemented all the logic in the 'authenticateByScreenName' method of a custom class that implements 'Authenticator'.
Example code:
public class ESBAuthenticator implements Authenticator{
public int authenticateByScreenName(long companyId, String screenName, String password,
Map<String, String[]> headerMap, Map<String, String[]> parameterMap)
setProfile(companyId, screenname);
return 1;
}
public static void setProfile(long companyId, long userId){
User user = UserLocalServiceUtil.getUser(userId);
Role liferayRole = RoleLocalServiceUtil.fetchRole(companyId, "Administrator");
RoleLocalServiceUtil.addUserRole(user.getUserId(), liferayRole.getRoleId());
UserLocalServiceUtil.updateUser(user);
}
}
When I log-in, apparently it works, I check liferay database's tables and they are updated, my user has "Administrator" role assigned. However, the portal in front-end doesn't show the "Admin" option.
But If I go to 'My Account', press the 'save' button, log-out and log-in again I have the Admin options availables.
Anyone know why this happens?, I am calling 'updateUser()' after assign the role, It is not the same as the 'save' button?
Possible solution:
I have found that If I clear the content cached across the cluster it works fine. I found it in this post:
https://www.liferay.com/es/web/kamesh.sampath1/blog/-/blogs/how-to-clear-liferay-cache
Add the following line:
MultiVMPoolUtil.clear();
Anyone know if is this the right solution?, I can't find what does liferay when the "save" button from the "my_account" page is pressed. Maybe it clear this cache?. I was searching for a synchronize with database function but couldn't find anything. It seems to be that if a column is updated, liferay doesn't use it if it's cached :(.
I can give you a cheap hack.
Step 1: Make sure you have the hold of user credential.
Step 2: Do as necessary to change user roles etc
Step 3: Flush all kinds of cache (client or server) related to the flow
Step 4: redirect the user to a temp view where the user credential you held will be applied automatically and then redirected to the portal.
Lemme know whether it works
When you call the method you are passing screenName
setProfile(companyId, screenname);
But in ur setProfileMethod, you are using UserId
public static void setProfile(long companyId, long userId){
User user = UserLocalServiceUtil.getUser(userId);
Role liferayRole = RoleLocalServiceUtil.fetchRole(companyId, "Administrator");
RoleLocalServiceUtil.addUserRole(user.getUserId(), liferayRole.getRoleId());
UserLocalServiceUtil.updateUser(user);
}
Use Method
UserLocalServiceUtil.fetchUserByScreenName(companyId, screenName)
I think that the solution of clear cache works because you need to remove all cached portlets repsones. This is the way my_account do it.
// Clear cached portlet responses
PortletSession portletSession = actionRequest.getPortletSession();
InvokerPortletImpl.clearResponses(portletSession);
The problem is that InvokerPortletImpl is not visible externally. to replicate this functionally you can try a login.events.post and get the responses cache from the HttpSession e clear the map;
httprequest.getSession().getAttribute("CACHE_PORTLET_RESPONSES").clear()
but it is like a hack its better in this case MultiVMPoolUtil.clear();
I'm using the following approach to return a Facebook user's music preferences:
//FIXME: Fetch results in a single operation
val likes = facebook.likeOperations().music
val artists = ArrayList<Artist>()
for (musicLiked in likes)
{
val musicProfile = facebook.fetchObject(musicLiked.id, Page::class.java, "id", "name", "genre");
artists.add(Artist(name = musicProfile.name, genre = musicProfile.genre))
}
The above approach won't scale, since we have an additional network operation for each artist the user likes.
I tried:
I tried using facebook.likeOperations.music however this doesn't fetch genre.
Question:
I would like to use facebook.fetchObject with a query that returns a PagedList. How to do this?
(No need to post example code in Kotlin if you prefer or are more familiar with Java - I'll be happy with information in any language).
Facebook api uses "fields" parameter in requests to return custom fields for objects. This parameter can be also used for liked music rest request.
me/music?fields=id,genre,name
above link will return all liked music with id, genre and name of the artist/group. Unfortunately FacebookTemplate does not have method which will apply for your needs. The method Facebook.likeOperations() returns instance of the LikeTemplate class which has constant PAGE_FIELDS with value
private static final String PAGE_FIELDS = "id,name,category,description,location,website,picture,phone,affiliation,company_overview,likes,checkins";
In above constant you do not have genre field. So you have two ways:
You can simply use facebook rest api with some rest library
You can override FacebookTemplate and return your own implementation of LikeTemplate as result of the likeOperations() method. You implementation of the LikeTemplate class should have different value in mentioned constant (added genre field at the end of the string)
Maybe some one will be more helpful but in my knowledge you do not have other options.
Thanks to advice given in #burovmarley's answer, I inspected the source and came up with:
val music = facebook.fetchConnections(userPage.id, "music", Page::class.java,
PagingParameters(25, 0, null, null).toMap(), "id,name,,genre")
for (musicLiked in music)
{
println("likes: ${musicLiked.name}, genre: ${musicLiked.genre}")
}
This allows using Spring Social Facebook as an unmodified dependency, and without issuing a pull request, which seem to be fairly slow in processing through the queue at the present time.
I am currently trying to enhance the To-Do List tutorial from Play framework's website. I've added a login form, (and of course a User class acting as a model), and it works perfectly well. I also made a small "dashboard" in which the logged user is able to change his password and his email address. But when I submit the form, I get a "Datasource user is null ?" error (RuntimeException).
The whole problem came when I wanted to restrict the edition possibilities (I first used a whole User form, which is quite over the top (User do not need to edit their ID). So I made a small inner class in my Application file called UpdateUser which gathers the required informations, just as I did for the login system.
Searching this error gave me many results but people saw their problem fixed by uncommenting the ebean.default line in the conf file, which I already did.
Here is the method I used to update user's informations :
Firstly, I made a small class in my Application to hold the form (exactly like I did for the login thing).
Then I made a update function as found here in my user class :
public static String update(String id, User newuser) {
newuser.update(id);
return("Your profile has been updated");
}
which returns the String that will be in my flash and which is according to my compiler the problem function.
This function is called in my Application like this :
public static Result updateUser(String id)
{
Form<UpdateUser> filledForm = updateUserForm.bindFromRequest();
System.out.println("Updated User : "+filledForm.get().id);
if(filledForm.hasErrors())
{
flash("success","Error while updating");
}else{
User user = new User(filledForm.get().id, filledForm.get().email, User.find.byId(filledForm.get().id).name, User.find.byId(filledForm.get().id).surname, filledForm.get().password);
flash("success", User.update(id,user));
}
return redirect(routes.Application.dashboard());
}
I tracked the data in the Form and it is not null (I mean I can get everything from the form). But I wonder if I have to create another ebean or if it's my function which is wrong. I also wonder if it's not my User creation that fail. Or maybe I should take the updateUser function and put it in my inner UpdateUser class ?
I have to admit that I worked on that all of yesterday (and probably today too), and I can't find anything on the internet except the ebean.default thing.
------EDIT
I continued to search, so here's what I tried :
1) Getting the form result into an instance of UpdateUser in order to use it
2) Use this instance instead of getting the data from the form
But it failed too. What's really weird is that I've added a toString() method for User class, and calling it on the user I want to insert (as an update) gives me the full stuff. I think it must be a configuration problem, but I can't see it.
Another thing : when I come to the error page and when I try to come back to the application by modifying the URL, I am disconnected. Is it my ebean that closes himself ?
Last edit for the day, I'm getting tired of this. I tried to delay the action (i.e. making it happen after the user has logged out), the new data are correctly saved but I still get the error when calling the update function.
Alright, I finally found it, but totally by chance.
I just had to write this :
public static String update(String id, User user) {
user.update((Object)id);
return ("Your profile has been updated");
}
Because for some reason that I don't really understand, The id String needs to be cast to Object. The rest of the code was correct. But apparently, when using update() on this particular case (is it because my id is a String or because I get the informations from another class before using it as my Model), the parameter which is supposed to be a String (even in the documentation) HAS to be cast.
That's it.
I am working in JAVA application and authenticating user through ITIM api. How to get groups accociated with user through ITIM api?
The system user will have an attribute of ‘erroles’ through which we can get information of user groups/Roles.
Get DistinguishedName from Person object.
Make PersonMO object having constructor like new PersonMO(platform, subject, person.getDistinguishedName());
Make new AccountManager(platform, subject);
This will give accounts collection accountManager.getAccounts(personMO, LocaleCreator.getLocale());
Get getSystemUserDN(userId);. PersonDao class will help in getting this.
Make new SystemUserMO(m_platform, m_subject, new DistinguishedName(systemUserDN));
Get the roles/Groups from systemUserMO.getData().getRoles()
Cheers

I am new to ITIM. I am working on an application in JAVA. I want to authorize users based on groups they are assigned to. How can I do that?
Is there any api that can fetch user roles/groups by which I can authorize them?
