"inStream parameter is null" Server Error(REST API)

I want to convert an old application to a new one in which i make HTTP calls (GET/POST/DELETE). I have a model package where i have my POJO classes and i made a DTO package where i have Dto classes. When i make a simple GET method to take a String message as a response i dont have any problem but when i use dependency injection and i want to use GET or POST methods to see some details about my app i get in postman this message: inStream parameter is null

edit your application.properties file like this
spring.jpa.hibernate.ddl-auto = update

Once you decided who is the "parent" in this relationship you should save the child first with its repository.
Lets assume it is the User.
You would do something like this in your controller
UserProfile newUser = user.getUserProfile();
userProfileRepository.save(newUser);
userRepository.save(user);
This guarantee garantee that the relation is successful.

ArrayList from user model returns null

So in the app I'm creating I have a user class defined as the following
public class User implements Serializable{
private int id;
private String username;
private String firstName;
private String lastName;
private String email;
private String password;
private String picture;
private ArrayList<String> tags;
private double rating;
private Category favorite;
private boolean star;
private Location homeLocation;
public User(int id, String username, String firstName,String lastName,String picture, ArrayList<String> tags,double rating, Category favorite, boolean star,Location homeLocation,String email,String password) {
this.id = id;
this.username = username;
this.firstName = firstName;
this.lastName = lastName;
this.picture = picture;
this.tags = tags;
this.rating = rating;
this.favorite = favorite;
this.star = star;
this.homeLocation = homeLocation;
this.email = email;
this.password = password;
}
public int getId() {
return id;
}
public String getUsername() {
return username;
}
public String getFirstName() {
return firstName;
}
public String getLastName(){ return lastName;}
public String getPicture(){ return picture;}
public ArrayList<String> getTags() {
return tags;
}
public double getRating(){ return rating;}
public Category getFavorite(){ return favorite;}
public Boolean getStar(){ return star;}
public Location getHomeLocation(){return homeLocation;}
public String getEmail(){return email;}
public String getPassword(){return password;}
public void setId(int id){
this.id = id;
}
Now, when I create a User object I pass an ArrayList<String> tags which, when logged, shows just as intended.
List<String> listTags = Arrays.asList(DummyTags.tagsNewUser);
ArrayList<String> tags = new ArrayList<>();
tags.addAll(listTags);
Log.d("Tags",tags.toString());
user = new User(0,userName,firstName,lastName,picturePlaceHolder,tags,4,category,true,loc,email,password);
However, when I use this user object in, say a profile page, and retrieve the users tags through the getter in the class it always returns null.
user = (User) getArguments().getSerializable("User");
tags = user.getTags();
Doing this always has tags be null, no matter what ArrayList I pass when creating the user object.
I also get a warning in android studio saying that invoking user.getTags() may produce a npe. Every other part of the user model works just fine. I have tried to solve this for a while now and have not been able to find anything relating to my problem so any help would be appreciated!

Try:
Bundle bundle=new Bundle();
bundle.putStringArrayList("tags",tags);
bundle.putSerializable("User",user);
and then retrieve as:
tags = getArguments().getStringArrayList("tags");
The reason that your solution does not work is that ArrayList is not implementing Serializable interface

JPA Eclipselink error inserting into table

So first a bit of back story. The issue I am having is when I create a user. Previously I had tried to create a user and assign them a role separately before discovering that by inserting into the SEC_USER_ROLE table the program was also inserting into the APP_USER table and I was getting an error about inserting duplicate values into the parent table. However, now by creating the user and role together I am getting the following error:
Primary key should be primitive (or list of primitives for composite
pk) , an instance of java.lang.Long with the primary keys filled in or
an instance of WebIntSecRole.......
Code as follows, not sure where I'm goin g wrong or the best solution at this point.
Admin.java:
//New User Creation
WebIntUser newUser = new WebIntUser();
newUser.setLoginId(newLoginName);
newUser.setCreatedBy(loggedUser);
newUser.setCreatedOn(today);
newUser.setDbAuth(true);
newUser.setDeleted(false);
newUser.setDisabled(false);
newUser.setEmail(newEmail);
newUser.setEncrypted(true);
newUser.setEncryptPassword(true);
newUser.setFirstName(newFirstName);
newUser.setLastName(newLastName);
newUser.setUpdatedBy(loggedUser);
newUser.setUpdatedOn(today);
newUser.setVersion(1);
newUser.setLdapId(1);
//userService.createUser(newUser);
//Set role for new user
WebIntSecRoleUser newUserRole = new WebIntSecRoleUser();
newUserRole.setUser(newUser);
newUserRole.setDeleted(false);
newUserRole.setRole(userService.selectRoleById(1));
//newUserRole.setCreatedBy(loggedUser);
//newUserRole.setCreatedOn(today);
//newUserRole.setUpdatedBy(loggedUser);
//newUserRole.setUpdatedOn(today);
newUserRole.setVersionNumber(0);
userService.createRole(newUserRole);

public WebIntUser getUser() {
return user;

}

}
Note: There is some commented out code that I'm either trying not to use anymore, or in the case of Created By and Created On etc I was getting errors for multiple inserts.

In my opinion you have missed the #ManyToOne mapping on the WebIntSecRole. You only specified the #JoinColumn.
#ManyToOne(/* desired options */)
#JoinColumn(name="ROLE_ID", nullable=false)
public WebIntSecRole getRole() {
return role;

Custom IDM authentication and Authorizer

I have custom implementation of the Picketlink IDM JPA authentication model. I got it by coping an example from there https://github.com/jboss-developer/jboss-picketlink-quickstarts/tree/master/picketlink-idm-custom-identity-model to package org.picketlink.idm.jpa.model.custom.simple. Then I have implemented this example https://github.com/pedroigor/picketlink-quickstarts/tree/master/picketlink-deltaspike-authorization .
I changed User class and UserTypeEntity in picketlink-idm-custom-identity-model example like this:
#IdentityStereotype(USER)
public class User extends AbstractIdentityType implements Account {
public static final QueryParameter USER_NAME = QUERY_ATTRIBUTE.byName("userName");
#StereotypeProperty(IDENTITY_USER_NAME)
#AttributeProperty
#Unique
private String userName;
#AttributeProperty
private String firstName;
#AttributeProperty
private String lastName;
#AttributeProperty
private String email;
#AttributeProperty
private String middleName;
#AttributeProperty
private String telephone;
#AttributeProperty
private String address;
#AttributeProperty
private int postIndex;
#AttributeProperty
private Date registerDate;
#AttributeProperty
private Date lastVisitDate;
#AttributeProperty
private boolean isOrganizer;
#AttributeProperty
private boolean isAdmin;
#Embedded
private Organizer organizer;
#Embedded
private Customer customer;
// getters and setters
}
class UserTypeEntity
#IdentityManaged(User.class)
#Entity
public class UserTypeEntity extends AbstractIdentityTypeEntity {
#AttributeValue
private String userName;
#OwnerReference
#ManyToOne(fetch = FetchType.LAZY)
private RealmTypeEntity realm;
#AttributeProperty
private String firstName;
#AttributeProperty
private String lastName;
#AttributeProperty
private String email;
#AttributeProperty
#Column(length = 255)
private String middleName;
#AttributeProperty
#Size(max = 12)
#Column(length = 12)
private String telephone;
#AttributeProperty
#Column(length = 5000)
#Size(max = 5000)
private String address;
#AttributeProperty
private int postIndex;
#AttributeProperty
private Date registerDate;
#AttributeProperty
private Date lastVisitDate;
#AttributeProperty
private boolean isOrganizer;
#AttributeProperty
private boolean isAdmin;
#Embedded
private Organizer organizer;
#Embedded
private Customer customer;
// getters and setters
}
Then I implemented Login controller:
#Named
#Stateless
public class LoginController {
#Inject
private Identity identity;
#Inject
private FacesContext facesContext;
public void login() {
AuthenticationResult result = identity.login();
if (AuthenticationResult.FAILED.equals(result)) {
facesContext.addMessage(
null,
new FacesMessage("Invalid user name or password"));
}
}
}
And Registration Controller:
#Named
#RequestScoped
public class RegistrationController {
private IdentityManager identityManager;
#Inject
private PartitionManager partitionManager;
#Inject
private FacesContext facesContext;
#Inject
private User user;
private String password;
private String passwordVerify;
private boolean isOrganizer;
public RegistrationController() {
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public String getPasswordVerify() {
return passwordVerify;
}
public void setPasswordVerify(String passwordVerify) {
this.passwordVerify = passwordVerify;
}
public boolean getIsOrganizer() {
return isOrganizer;
}
public void setIsOrganizer(boolean isOrganizer) {
this.isOrganizer = isOrganizer;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
#Transactional
public String register() throws Exception {
if (password.isEmpty()) {
String message = LocaleBean.loadErrorMessage(facesContext, LocaleBean.EX_RESOURCE_BUNDLE_NAME, "password.empty");
facesContext.addMessage("signup:registrationPassword", new FacesMessage(message));
return "returnToSignup";
}
if (!password.equals(passwordVerify)) {
String message = LocaleBean.loadErrorMessage(facesContext, LocaleBean.EX_RESOURCE_BUNDLE_NAME, "password.NotEqual");
facesContext.addMessage("signup:registrationPassword", new FacesMessage(message));
return "returnToSignup";
}
identityManager = partitionManager.createIdentityManager(partitionManager.getPartition(Realm.class,
Resources.REALM_ACME_NAME));
if (isOrganizer) {
user.setOrganizer(true);
user.setOrganizer(new Organizer());
try {
identityManager.add(user);
} catch (IdentityManagementException e) {
String message = LocaleBean.loadErrorMessage(facesContext, LocaleBean.EX_RESOURCE_BUNDLE_NAME, "login.Registered");
facesContext.addMessage(null, new FacesMessage(message));
return "returnToSignup";
}
Password password = new Password(this.password);
identityManager.updateCredential(user, password);
RelationshipManager relationshipManager = partitionManager.createRelationshipManager();
IdentityQuery<Group> query = identityManager.createIdentityQuery(Group.class);
// query all childs of sales unit
query.setParameter(Group.NAME, Resources.ORGANIZERS_GROUP_NAME);
List<Group> groups = query.getResultList();
Group organizersGroup = groups.get(0);
relationshipManager.add(new GroupMembership(user, organizersGroup));
} else {
}
return "signin";
}
}
After that I implemented Authorizer:
#ApplicationScoped
public class SPAuthorizer {
#Secures
#Admins
public boolean doAdminsCheck(Identity identity, IdentityManager identityManager, RelationshipManager relationshipManager) throws Exception {
return hasGroup(identity, identityManager, relationshipManager, Resources.ADMINS_GROUP_NAME);
}
#Secures
#Organizers
public boolean doOrganizersCheck(Identity identity, IdentityManager identityManager, RelationshipManager relationshipManager) throws Exception {
return hasGroup(identity, identityManager, relationshipManager, Resources.ORGANIZERS_GROUP_NAME);
}
#Secures
#Customers
public boolean doCustomersCheck(Identity identity, IdentityManager identityManager, RelationshipManager relationshipManager) throws Exception {
return hasGroup(identity, identityManager, relationshipManager, Resources.CUSTOMERS_GROUP_NAME);
}
private boolean hasGroup(Identity identity, IdentityManager identityManager, RelationshipManager relationshipManager,
String groupName) {
IdentityQuery<Group> queryGroup = identityManager.createIdentityQuery(Group.class);
// query all childs of sales unit
queryGroup.setParameter(Group.NAME, groupName);
List<Group> groups = queryGroup.getResultList();
if (groups.size() == 1) {
Group group = groups.get(0);
Account user = identity.getAccount();
if (user == null) {
return false;
}
RelationshipQuery<GroupMembership> query = relationshipManager.createRelationshipQuery(GroupMembership.class);
query.setParameter(GroupMembership.GROUP, group);
query.setParameter(GroupMembership.MEMBER, user);
// user is assigned with two groups
List<GroupMembership> resultList = query.getResultList();
return resultList.size() > 0;
}
return false;
}
}
So I implemented authorization checker to check belonging user to a some group in JSF:
#Named
#Stateless
public class AuthorizationChecker {
#Inject
private Identity identity;
#Inject
private PartitionManager partitionManager;
public boolean hasGroup(String groupName) {
IdentityManager identityManager = partitionManager.createIdentityManager(partitionManager.getPartition(Realm.class,
Resources.REALM_ACME_NAME));
IdentityQuery<Group> queryGroup = identityManager.createIdentityQuery(Group.class);
// query all childs of sales unit
queryGroup.setParameter(Group.NAME, groupName);
List<Group> groups = queryGroup.getResultList();
if (groups.size() == 1) {
Group group = groups.get(0);
Account user = identity.getAccount();
RelationshipManager relationshipManager = partitionManager.createRelationshipManager();
RelationshipQuery<GroupMembership> query = relationshipManager.createRelationshipQuery(GroupMembership.class);
query.setParameter(GroupMembership.GROUP, group);
query.setParameter(GroupMembership.MEMBER, user);
// user is assigned with two groups
List<GroupMembership> resultList = query.getResultList();
return resultList.size() > 0;
}
return false;
}
}
But an instance of Identity in hasGroup of the SPAuthorizer doesn't corresponds to an instance that I have in AuthorizationChecker. I checked it in debugger. And when I do identity.getAccount(); it returns null although user was authenticated. Any idea what to do?

The problem was in missed annotation #Stateless in Controller.
There is workable example https://github.com/lynx-r/picketlink-deltaspike-authorization-and-idm-custom-identity-model.
