Am having a entity object as below and when I try to delete the Parent entity object am getting the "org.apache.openjpa.persistence.ArgumentException" but am not sure what is the reason for this exception.
Class Parent implements Serializable
{
#ID
#column(name="ParentKey")
String parentKey;
#manytomany
#jointabel(name="Association_Parent_Child",joinColumns{ #joinColumn,#inversejoinColumn})
List<Child> Childs;
}
Below is the Child Entity
Class Child implements Serializabe
{
#ID
#column(name="childKey")
String childKey;
#ManyToMany(mappedBy = "Childs", fetch = FetchType.EAGER)
List<Parent> parents;
#onetomany
List<someOtherClassX> x;
#onetomany
List<SomeotherClassY> y;
}
In my DAO Implementation Layer . I have a delete Method
Parent DeletParent = new Parent ();
DeletParent .setParentKey("ID");
When I call entitymanager.remove("DeletParent ");
<openjpa-2.0.0-r422266:935683 nonfatal user error> org.apache.openjpa.persistence.ArgumentException:

Any suggestions , As per the exception should we populate the child object . Why do we have to populate the child object here.?
Try this in the parent:
#ManyToMany(cascade = CascadeType.DETACH)

I'm trying to retrieve data using my Hibernate One to Many relation but failing. I'm trying to get all Bookmarked_rooms from Account. Here is my query:
public RoomList findBookmarkedRooms(String name) {
Query query = em.createQuery("FROM Room r WHERE r.roomid in(SELECT Room_id FROM Bookmarked_rooms a )");
List rooms = query.getResultList();;
if (rooms.size() == 0) {
return null;
} else {
return new RoomList(rooms);
}
}
Here is my Account and Room entity given separately:
public class Account {
#Id
#GeneratedValue
private Long id;
#Column(name="username",unique=true,nullable=false)
private String username;
#OneToMany
#JoinTable(name = "Bookmarked_rooms", joinColumns = #JoinColumn(name="Account_id"), inverseJoinColumns = #JoinColumn(name="Room_id"))
private Collection<Room> bookmarkedroom = new ArrayList<Room>();
//Getters and Setters
}
Room entity:
public class Room {
#Id
#GeneratedValue
private long roomid;
#Column(name="roomname",unique=true,nullable=false)
private String roomname;
private String description;
//Getters and Setters
}
When I run the query I've following error:
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Bookmarked_rooms is not mapped [FROM web.core.models.entities.Room r WHERE r.roomid in(SELECT Room_id FROM Bookmarked_rooms a )]

I'm not understanding what is my actual error. If the error is my query, please some one demonstrate me the right query.
You could simply do it from the other end.
select markedroom from Account a
inner join a.bookmarkedroom markedroom
This could help you.
I have the following specification which is supposed to check if the Magazines of a File are in a list of Magazines under a Subscription:
public static Specification<File> getContainingMagazines(final long subscriptionId){
return new Specification<File>() {
#Override
public Predicate toPredicate(Root<File> root, CriteriaQuery<?> query, CriteriaBuilder cb) {
Subquery<Subscription> subscriptionSubquery = query.subquery(Subscription.class);
Root<Subscription> subscriptionRoot = subscriptionSubquery.from(Subscription.class);
ListJoin<Subscription, Magazine> subscriptionMagazineJoin = subscriptionRoot.join(Subscription_.magazines);
Path<Long> subscriptionIdPath = subscriptionRoot.get(Subscription_.id);
subscriptionSubquery.
select(subscriptionRoot).
where(cb.equal(subscriptionIdPath, subscriptionId));
ListJoin<File, Magazine> magazinesJoin = root.join(File_.magazines);
return cb.and(magazinesJoin.get(Magazine_.id).in(subscriptionMagazineJoin.get(Magazine_.id)));
}
};
}
And in my service I'm doing this:
public int findFilesWithSubscription(long subscriptionId) {
List<File> fileList = fileRepository.findAll(FileSpecs.getContainingMagazines(subscriptionId));
return fileList.size();
}
The entities involved are the following:
#Entity
#Table(name = "nim_file")
public class File
#ManyToMany(fetch = FetchType.LAZY)
#JoinTable(
name = "nim_file_magazines",
joinColumns = #JoinColumn(name = "file_id"),
inverseJoinColumns = #JoinColumn(name = "magazine_id")
)
private List<Magazine> magazines;
and
#Entity
#Table(name = "nim_subscription")
public class Subscription
#ManyToMany(fetch = FetchType.EAGER)
#JoinTable(name = "nim_subscription_magazines",
joinColumns = #JoinColumn(name = "subscription_id"),
inverseJoinColumns = #JoinColumn(name = "magazine_id")
)
private List<Magazine> magazines;
finally
#Entity
#Table(name = "nim_magazine")
public class Magazine
This last one is a lookup table pretty much.
Now I'm testing using DWR, because I couldn't find a better way to test quickly and so far there is no stack trace nor sql shown even though hibernate has setShowSql(true). I only get this message:
2300777 [http-bio-9090-exec-4] WARN o.d.dwrp.BaseCallMarshaller - --Erroring: batchId[2] message[java.lang.NullPointerException]
So my questions are these:
What am I doing wrong?
How can I test/debug specifications and/or predicates better than dwr so I can get stack traces and such?
Edit
Upon some move to a Junit test class I obtained the following stack trace:
java.lang.NullPointerException

I always found the Criteria API very cumbersome to use and it may generate horrible SQL statements even for trivial joins.
Try this HQL query instead:
select f
from File f
inner join f.magazines file_magazine
where exists (
select s
from Subscription s
inner join s.magazines subscr_magazine
where s.id = :subscription_id and subscr_magazine.id = file_magazine.id
)
While you can also check any/some/member of, those expressions can lead to very complicated SQL queries. Try the suggested sub-select and see how it goes.
I am not sure if this works but you can also use the with extra join clause:
select f
from File f
inner join f.magazines file_magazine
where exists (
select s
from Subscription s
inner join s.magazines subscr_magazine with subscr_magazine.id = file_magazine.id
where s.id = :subscription_id
)
For logging al SQL queries along with parameters you can set up a datasurce-proxy in front of your application data source.
I am new to Hibernate. I am trying extend the baseClass and perform findById. Can anyone let me know, if we can do this? If not this way, any other possible way where I can add new values. I don't want to change the BaseClass(i can t change it, strictly). there is no ExtendedClass table in the database.
#Entity
public class BaseClass
{
#Id
private Integer id;
#Column(name = "PERS_NAME")
private String personName;
//getters and setters
}
#Entity
public class ExtendedClass extends BaseClass
{
#Column("EMAIL")
private String email; //getter and setter
}
main method:
ExtendedClass extClass = null;
extClass = hibernateTestDao.findById(id);
This generates the query something like
Hibernate:
select
baset0_.id as id296_0_,
baset0_.PERS_NAME asPERS3_296_0_,
baset0_.EMAIL as EMAIL8_296_0_
from
BaseClass baset0_
where

The idea of a baseclass is a bit different. In there you would have all the variables that are common to every entity object that derive from it. For your base class you would want to take a look at #MappedSuperclass annotation instead. In your base class then you provide a protected/public getter for your id variable.
I have this class (simplified from real code):
#Entity
KeyVal{
#Id private int id;
#ElementCollection private Collection<String> keys;
#ElementCollection private Collection<String> values;
}
I want to be able to extract all KeyVals holding a specific key.
Something similar to:
List<KeyVal> getByKey(String key) {
return getSession().createCriteria(KeyVal.class)
.add(Restriction.eq("keys",key)).list();
}
However that code yields:

strangely enough it seems like this is easy for complex types (from Hibernate documentation):
List cats = sess.createCriteria(Cat.class)
.add( Restrictions.like("name", "F%") )
.createCriteria("kittens")
.add( Restrictions.like("name", "F%") )
.list();
can you try createAlias?
List<KeyVal> getByKey(String key)
{
return getSession().createCriteria(KeyVal.class)
.createAlias("keys", "key")
.add(Restriction.eq("key",key))
.list();
}
I have the next persistence capable classes:
#PersistenceCapable
public class AppAccount {
#PrimaryKey
#Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
#Persistent
private String companyName;
#Persistent
List<AppUser> users = new ArrayList<AppUser>();
// Getters and Setters and other properties
}
#PersistenceCapable
#EmbeddedOnly
public class AppUser {
#Persistent
private String username;
#Persistent
private String firstName;
#Persistent
private String lastName;
// Getters and Setters and other properties
}
Based on an application account id, I want to retrieve a list of the users:
public static List<AppUser> getUsers(Long application_id) {
PersistenceManager pm = JdoUtil.getPm();
Query q = pm.newQuery(
" select users " +
" from " + AppAccount.class.getSimpleName() +
" where id == idParam" +
" parameters Long idParam");
return (List<AppUser>) q.execute(application_id);
}
I get the next error:

Why use getSimpleName() since that just puts the class name? JDOQL requires the class name, including package as per the JDO spec (getName() is better). Also you do NOT need #Persistent on String fields no matter what Google tells you :-P Saludos
