[JBoss-user] [EJB 3.0] - Using @SequenceGenerator ...
Hi there! I'm using JBoss 4.0.4.GA + Oracle 10g and an individual sequence for the PKs of each enity. In some entities I need to init several fixed records with known identities. So I prefer to use low values for the reserved primary keys (let's say between 1 and 100) and use greater identities for the dynamic data that is going to be inserted during the regular app work... 1. Is there a way to use the @GeneratedValue annotation, but override its behaviour when it comes to the fixed records? If I manually set the ID before trying to persist or inside a @PrePersist callback, Hibernate designedly raises an exception. So I can omit the @GeneratedValue and set the id always manually (getting the sequence NEXTVAL when necessary), but it is not the cleanest way to achieve the goal. Is there some better way? 2. To reserve some range for the initial identities, the initialValue attribute in the @SequenceGenerator annotation would be a perfect solution, but it does not seem to work?

[JBoss-user] [EJB 3.0] - @OrderBy does not work as expected?
I have an entity bean, which has a @ManyToMany association to itself. But it
appears that the @OrderBy annotation is not functioning in this case... (no
exceptions - just the result is not sorted at all)
Example:
@Entity
| public class Client implements Serializable {
|
| private ListClient partners;
|
| //.
|
| @ManyToMany
| @OrderBy(name) // I tried different fields, but no effect...
| // the default should sort by id, but it doesn't work
either
| public ListClient getPartners() {
| return partners;
| }
|
| public void setPartners(ListClient partners) {
| this.partners = partners;
| }
|
| }

[JBoss-user] [EJB 3.0] - Re: ora-00972
Well.. unfortunately Oracle will not allow you to use column names, longer than 30 chars. I suppose this is the problem you encounter. Check the length of your property name and consider the naming strategy you use? For example, using org.hibernate.cfg.DefaultComponentSafeNamingStrategy and several levels of embedded properties, can easily interfere with this Oracle limitation when trying to generate names like customer_address_municipality_id:( If this is not the case, it's not a bad idea to paste some code, logs...?

[JBoss-user] [EJB 3.0] - Re: DAO-JDBC vs. EJB3
The explanations provided in http://www.hibernate.org/15.html and http://www.hibernate.org/157.html I find very comprehensive and substantial. The issues related to performance have always been very easy to be misunderstood and wrongly interpreted... I just want to mention that using DAO JDBC forces you to work on a lower level, which means that you are less likely to do unnecessary things. When using additional layer (even the best ORM) it is often much easier to do wrong things that slow down the performance (like unnecessary eager collections objects). But it does not mean that the problem is in the ORM itself. As a matter of fact, I am not too proficient in hibernate, but I think that it is pretty good at what it does. So, I'd almost always prefer hibernate3/EJB3 (with annotations) to JDBC/DAO, because I find that these technologies have more pros than cons. As a comparison, I'll mention that I'd almost never prefer EJB2 persistence to JDBC/DAO...

[JBoss-user] [EJB 3.0] - EJB class in SAR not reloaded during redeploy
JBoss 4.0.4 CR 2, EJB3 An application with multiple .ear files, a common .jar and a .sar file. The common.jar contains the component (local) interface of a SLSB. The SLSB impl is in one of the ears. Everything works fine, but the problem appears in the SAR file when the application is redeployed. It works fine in ALL of the ears, which are using this ejb (no matter how many times I redeploy) So I found the following: when I deploy the first time after starting JBoss, all ejb clients (both sar and ears) retrieve the ejb object w/o a problem. But when I redeploy, the ejb object retrieved by the JNDI lookup in the SAR file is an instance of the same (the old, first loaded) EJB class. There is no problem when retrievig the EJB from any of the ears, because they receive an instance of a new (obviously reloaded) class, which is an instanceof the NEW local interface. So I get a ClassCastException, because the EJB interface is reloaded and I am trying to cast the ejb impl which is still instanceof the OLD EJB Interface. This is probably expected behaviour for a SAR, but it is making troubles in this case. Any ideas how to cope with this? Maybe I need to configure JBoss somehow..?

[JBoss-user] [EJB 3.0] - Cannot recognize polymorphic properties in a query
I have a structure like this:
@Entity

| //...
| }
|
| @Entity
| @Inheritance(strategy = InheritanceType.JOINED)
| public abstract class Person {...}
|
| @Entity
| public class Student extends Person {
| SomeType someStudentProperty;
| //...
| }
|
| @Entity
| public class Teacher extends Person {...}
I want to query the users with testing the someStudentProperty in the where
clause, but it doesn't work...
from User u where u.person.someStudentProperty = whatsoever...
(from User u where u.person.somePersonProperty = whatsoever... works
correctly)
Is it a bug, I miss something, or it is not a supported feature?

anonymous wrote : From my understanding of polymophism I wouldnt call this a polymorphic query I did not say polymorphic query. I used the term polymorphic properties in a query. Anyway, it might be not the most proper way to call it. The question is about using properties declared in an inherited class of the ref type. Obviously the loaded person object will be of type Student or Teacher. What I'm interested in is how to query only the users having for person a student, that satisfies a certain condition...

[JBoss-user] [EJB 3.0] - Persisting enum fields with custom value mapping
Let's say we have an enum with custom values, used as a persistent field in an
entity:
public enum Sex {
|
| MALE(77),
| FEMALE(99);
|
| public int getValue() {
| return value;
| }
|
| int value;
|
| Sex(int v) {
| value = v;
| }
| }
The spec defines two ways to map the enum property with the DB field:
Sex.MALE = 0
| Sex.FEMALE = 1
| // the default one, i.e. the var.ordinal() value
|
or
Sex.MALE = MALE
| Sex.FEMALE = FEMALE
| // using @Enumerated(STRING)
|
|
That's ok, but is there an easy way to use some kind of custom mapping?
In this case:
Sex.MALE = 77
| Sex.FEMALE = 99
| // i.e. the user-defined var.getValue() result
|

[JBoss-user] [EJB/JBoss] - JBoss and user threads and sockets
We use the last version of JBoss with EJB3. We need to start a TCP/IP ServerSocket in our JBoss application, listening all the time the app is running. Is there a problem to do this in JBoss? Is it allowed, and is there a danger JBoss to decide to influence the thread(s) I start? By the way, the EJB specification (for both 2 and 3) states that: anonymous wrote : The enterprise bean must not attempt to manage threads. The enterprise bean must not attempt | to start, stop, suspend, or resume a thread; or to change a thread?s priority or name. The enterprise | bean must not attempt to manage thread groups. Well, they say The enterprise bean must not attempt to manage threads. But does it mean that this restriction is not related to other classes deployed in the EJB container?
