[jboss-user] [EJB 3.0] - Deploying EAR and WAR separately
I have some EJBs in an EAR file that I want to use in a separately deployed WAR file. I figured making them use the same unified class loader through jboss-app.xml/jboss-web.xml would solve this problem, but I'm still getting ClassNotFoundExceptions when I attempt to load the appropriate classes from the WAR. When deploying them in the same EAR, everything works fine. Could someone point out the appropriate way to do this?

[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Criteria queries and collection valued properties
Suppose I have a Set of Integers as a collection valued property in an entity class, and I want to include it in the results (projection) of a criteria query, how do I do it? The Hibernate documentation only explains how to do it for associations. If I try to map it to an alias, I get a MappingException saying collection was not an association: Trying to add it directly as a projection with Projections.property() only gives me the root entity's ID for some reason. Regardless of whether I set the fetch mode for the collection property to JOIN or not, Hibernate refuses to fetch it in the query. Why is this happening?

[jboss-user] [EJB 3.0] - Re: Table per class with different ID generators
The problem is that I have an Employee object associated with every Document. When the Employee goes away, the link has to be severed. Being able to do that implicitly (with cascade=CascadeType.REMOVE) would be the ideal solution. Right now I have a hack involving a custom annotation, parameter injection and an UPDATE query that fires whenever an Employee is deleted. Being able to have an association to Document directly would be a much cleaner solution. Document doesn't have its own table so it doesn't need a PK of its own. It'd be great if I could have getId() defined in Document, and override it in subclasses and set @GeneratedValue along with any specific generators there. I don't see any theoretical problems with that approach.

Why are you using the data source directly? Not that it's the cause of your problem, but IMHO EJB3 Persistence should be used instead unless you have a good reason not to. Where did you deploy your data source? Could you show its deployment descriptor? Also, when you look up beans remotely, you need to add the application name to the path, like MyApp/MyBean/remote.

[jboss-user] [JBoss Seam] - Re: When to use SessionBeans and when Pojos?
You only have to use @Remote when you plan to make the session bean available to clients outside the container JVM (for a client application). There are a number of advantages to using EJB3 session beans instead of POJOs. SFSB replication across the cluster is handled by the container, as is persistence context injection and transaction demarcation. As I recall, the Seam documentation says that SFSB replication across the cluster is more efficient than that of Seam POJO components.

[jboss-user] [JBoss Seam] - Re: Seam binary content downloads
Okay, it seems to use a servlet that looks up an application scoped component to get hold of an EntityManager instance. This would seem like a better solution than a JNDI lookup that I was doing in my servlet. The s:download or whatever would still be greatly appreaciated. The Wiki example seems fairly outdated (look at web.xml). Should I create a JIRA issue on that, or is Christian planning to fix it by 2.0.0GA?

There may be an obvious solution to this that I've completely missed, but here goes: What's the best way to allow the user to download arbitrary generated binary content (forum file attachments)? I was thinking of a servlet based solution, but getting hold of an entity manager instance in a pre-JEE5 container is kinda cumbersome. Perhaps there is a simpler solution, maybe involving Seam (and its resource servlet)?

[jboss-user] [JBoss Seam] - PersistenceContext injection in Seam 2.0beta1
Trying to inject a Hibernate Session with @PersistenceContext fails:
anonymous wrote :
| java.lang.ClassCastException: $Proxy1497 cannot be cast to
javax.persistence.EntityManager
The reason for this was pretty obvious once I took a look at the code of
org.jboss.seam.intercept.SessionBeanInterceptor:
| ...
| //wrap any @PersistenceContext attributes in our proxy
| for ( BijectedAttribute ba:
getComponent().getPersistenceContextAttributes() )
| {
| EntityManager entityManager = (EntityManager) ba.get(bean);
| if ( ! (entityManager instanceof EntityManagerProxy ) )
| {
|ba.set( bean, new EntityManagerProxy(entityManager) );
| }
| }
| ...
|
Apparently it doesn't even look at the field type, and always assumes that I
want to inject an EntityManager. Even if I do inject an EntityManager, then
#getDelegate() won't give me a Session, as it would without Seam. How the heck
do I directly inject a Hibernate Session??

I need to display a nested list as follows: Root category 1 | Subcategory 1 | Subcategory 2 | Root category 2 | Subcategory 3 I first tried doing this using the Facelets ui:repeat element, only to find out that only the outer layer (the root categories) were rendered. Using JSTL's c:forEach fixed this, but caching no longer works as intended, since I'm getting database hits on every pageload. I have a similar page elsewhere that uses ui:repeat instead, and caching works fine there. This is quite annoying since constructing said list is fairly database intensive and the data rarely changes. Any advice?

This is a JBoss bug. Class loading was done in the wrong manner, relying on an unintended side effect of the class loading mechanism, and when the behavior changed in Java 6, it broke a lot of software. What you see there is a failed attempt at loading the class for String[], not String. JBoss AS 5.0 is supposed to be free of these issues once it's finished.

@Local only works if the calling end is running within the same VM as the server. Therefore you need to use @Remote instead if you want your beans to work with application clients. Why are you still trying to get dependency injection to work? Last I heard it doesn't work with JBoss at all -- and it's awful in Glassfish too. Just give it up and use JNDI lookups just like everyone else does.

[jboss-user] [EJB 3.0] - Re: My own EntityManager, how to do it?
I was about to ask the same question, but then I saw this post. My solution is to just use @EJB ExtEntityManager em; instead of @PersistenceContext EntityManager em;, but if you use multiple persistence units, it may not be such a practical approach.

Ah yes, I had forgotten about this thread :( This is probably related to the problem I've been having. What was the cause?

[jboss-user] [JBoss Seam] - Re: Seam enhanced EL expression fails in an Ajax4JSF tag
Ok, I've been busy trying to figure out WTF is wrong with this. According to my research, Ajax4JSF + Facelets = bust. I created a very simple page with one managed bean, no Seam involved. a4j:commandLink causes an error message if Facelets is involved, but works fine on the corresponding JSP page. If I change a4j:commandLink to h:commandLink, then even the facelets page renders fine. You can download the test project here: http://paradoxx.dyndns.org/TestWeb.tar.gz I tried several different versions of both Facelets and Ajax4JSF, to no avail.

| body
| a4j:form
| a4j:commandLink value=Test action=#{categorybean.jumpPage}

| /html
I still get the error message:
/hello.xhtml: Property 'jumpPage' not found on type

It'd help if I could find so much as a single working app that used
a4j:commandLink.

[jboss-user] [EJB 3.0] - Re: JNDI and Client Application
First of all, when you ask for help, enclose your code with the code tag (use the buttons provided). Next, package your session beans in a .jar file. The .ejb3 extension is deprecated. Third, the correct JNDI path is //(remote|local). Just because you packaged your beans in a directory named beans doesn't mean it has anything to do with JNDI bindings. Session beans are usually part of some application, and (afaik) the application name dictates the default binding for them. You can find out if your beans were deployed correctly by checking the JNDI browser in the JMX console of JBoss. There are plenty of examples regarding this -- try out some of them before asking for help here.

[jboss-user] [JBoss Eclipse IDE (users)] - Re: This IDE won't update?
Thank you, but could we get an unofficial estimate when beta3 will likely be released? A lot of that banging head to the wall comes from the fact that the xml descriptor was incorrectly configured and resulted in Eclipse thinking that the IDE needed its own copy of WTP. That was fixed a long ago in the CVS but I'd rather not venture there, given the volatile nature of development code. Some tried that and failed. Therefore a new release would be greatly appreciated. It's been far too long since beta2.

Sorry again, folks -- false alarm! Turns out I was including jbossall-client.jar on the list of resources in my application's JNLP file, and apparently that jar contains the old remoting code, which caused the exception.

Probably when they fix the rest of the components (JGroups etc.) that have this same bug, since I don't think they'll make any official releases before they can run the complete test suite.

Not to my knowledge, but jbossall-client does not contain anything unique. It's just a bunch of existing jars thrown together for convenience.

You can instruct MySQL to create InnoDB tables by default. Just put | default-table-type=innodb | under [mysqld], and you're set.

[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - HQL and enum constants
According to the Hibernate manual, it is possible to use public static final constants directly in HQL queries. Why then can I not use enums there as well? I tried | SELECT DISTINCT m FROM Material m, IN(m.suppliers) s WHERE m.unit Material.MaterialUnit.SQUARE_METRES AND s.id = :id | and variations like MaterialUnit.SQUARE_METRES and the fully qualified name, but they all produce the same error message on deployment: anonymous wrote : | 13:55:36,982 ERROR [SessionFactoryImpl] Error in named query: Material.nonCuttables | org.hibernate.hql.ast.QuerySyntaxException: Invalid path: 'null.MaterialUnit.SQUARE_METRES' [SELECT DISTINCT m FROM fi.karico.etikettu.domain.Material m, IN(m.suppliers) s WHERE m.unit Material.MaterialUnit.SQUARE_METRES AND s.id = :id] | The same works fine if I just input the enum as a parameter: | SELECT DISTINCT m FROM Material m, IN(m.suppliers) s WHERE m.unit :m2unit AND s.id = :id | What am I doing wrong?

For the record, here's the code for the MaterialUnit enum inside the Material
class:
| public enum MaterialUnit {
| SQUARE_METRES(m\u00b2),
| ROLLS(rll),
| PIECES(kpl),
| KILOGRAMS(kg);

| private final String name;

| private MaterialUnit(final String name) {

[jboss-user] [EJB 3.0] - Re: relationship does not prevent from deleting referenced e
Have you checked whether the correct foreign keys are in place in the database? If not, have you tried to drop the tables and allow Hibernate (which I assume you're using) to generate the tables again? On a side note, a few non related tips for you: 1. You don't need an explicit constructor if the sole constructor is public and has no arguments. Calling super() is useless if the class only extends java.lang.Object. 2. When defining relationships, you don't need to specify targetEntity when using generics. 3. You don't EVER have to specify strategy = GenerationType.AUTO, since it's the default anyway. 4. Always use English for variable and method names. Makes your software more consistent and maintainable.

[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Hibernate and @CollectionId
Could someone help me understand why @CollectionId is required for multiple simultaneous bag fetching? All it does is create an invisible primary key for the collection. I understand this in the case of unidirectional relationships, but if I have a bidirectional relationship, what purpose does this serve, since the referenced entity already has a primary key? Why can't hibernate use the target entity's existing primary key?

[jboss-user] [EJB 3.0] - Re: Stateful Bean and the database commit
To my knowledge, m.flush() guarantees that the database commit happens before the method returns (or else it will throw an exception). I can't understand why you inject an EntityManagerFactory instead of an EntityManager. What is the purpose of afterCompletion()? And why is the bean stateful and not stateless? I don't see any state variables that would warrant a stateful bean.
