[jboss-user] [JNDI and Naming] - EJB 3.1 Global JNDI names
Hello, I am testing on JBoss 6 some of the new EJB3.1 features. On JNDIView in JMX Console I see that I am getting the same JNDI naming as with JBoss 5.1 Do I have to make any changes in JBoss or in any xml deployment description to make a ear or war file be recognized as EJB 3.1 and so get then Global JNDI standarized naming?

[jboss-user] [EJB 3.0 Users] - Session EJB 3.1 packaged in war file not recognized in JBoss
Hello, I am trying to repackage a small EJB3 application moving the EJB jar file to .war's /WEB-INF/lib and deploying only that war, as docs say can be done with EJB3.1 specs. The Entity EJBs in that jar are recognized OK as hibernate logs show, but JBoss seems to ignore the Stateless Session Bean. When I deploy it according to EJB 3.0 specs (ear=war+jar) the SSB deploys of and appears in JNDIView in JMX Console. Do I have to make any special xml file or modification to JBoss to make it recognize the SSB? Of course, I am using new JBoss 6, which is supposed to support new EJB 3.1 .

[jboss-user] [JNDI and Naming] - Default JNDI name changed after recompiling
Hi there, I have just migrated an application from JBoss 4 and Java 5 to JBoss 5.1 and Java 6. It worked OK... my Stateless Session Beans had a remote JNDi name like: UserManager/remote (as all docs state is the default remote name). For some reason I had implemented @Remote both in the interface and in the bean class itself. That worked ok in JBoss 4 but JBoss 5.1 started giving problems when deploying so I removed @Remote from the bean and left it just in the interface (as it is supposed to be done). Now the standard bean JNDI name has changed from "UserManager/remote" to "UserManager/remote-com.mypackage.UserManager" Is that normal? Anybody can give me any ideas on the reason for this? I have had to change the hardcoded standard lookup code in the clients or make xml deploying descriptors.

[jboss-user] [Persistence] - Isolated ears with same name persistence unit
Hello, I am deploying two different apps in two ears in JBoss 5.1. They deployed OK in JBoss 4. As I reuse compiled JEE5 classes and I use annotations, the persistence unit used in both application has the same name: "mainPersistenceUnit" (it has to be hardcoded). this was not a problem with JBoss 4; in the "persistence.xml" archive in the EJB jar I point to each different data source.

[jboss-user] [Installation, Configuration & Deployment] - Re: Multiple JBoss instances vs. one
Hello, thanks for the links. I had of course read them before posting but, sorry, I can't find definite information there about having to activate CallByValue. I'm sure I'm missing something. In my scenario I have to deploy two .ears and two .wars. I use classloading configuration for 2 different repositories in jboss-web.xml and jboss-app.xml I need to do this as I cannot include the war's inside the .ears. In JBoss I am activating isolation in ear-deployer-jboss-beans.xml but deactivating CallByValue. I also deactivate CallByValue in jboss-service.xml In war-deployers-jboss-beans.xml I deactivate java2ClassLoadingCompliance, as well as in jboss-app.xml and jboss-web.xml This should enable isolation while not activating CallByValue. I'll make checks with both apps. If anybody knows any configuration file I might me missing please point me to any direction.

[jboss-user] [Installation, Configuration & Deployment] - Multiple JBoss instances vs. one "big" JBoss with different
hello, I start this thread to get opinions on which is the best approach when needing to deploy multiple different applications in the same server. I've been using JBoss for years starting with version 3. During this time I've used a couple of JBoss instances with scope class loading, even though docs state that disabling unified class loading and enabling marshaning (CallByValue?) is CPU consuming. I am migrating now to JBoss 5.1 and have decided to test keeping unified class loading and starting multiple JBoss'es in differennt localhost IPs. (I cannot deploy different applications in the same instance as I have many version conflicts. I use multiple versions of my own EJB3 component library) These JBoss will need less memory than the previous one and only JBoss. Of course, they are faster now. is this approach right? I use MacOS and its Java VM, while not specially fast, it is suppoused to handle memory sharing between different java instances. Maybe there is a different approach for deploying different apps in the same server... as far as I know there is no way to enable isolated class loading without enabling "CallByValue"... is there? Thanks for any advice/experiences.

[jboss-user] [EJB 3.0 Users] - Re: Migrating .ear to JBoss 5 with several EJB3 Jars inside
Well, they are EJB3 entities. I guest they have most in common with HJPA/Hibernate entities but I try not to code anything outside EJB3 specifications, so I never deal with Hibernate in my code, even though I know it is there taking care of EJB3 persistence. May I ask if dealing with Hibernate specifically can solve my problem?

[jboss-user] [Installation, Configuration & Deployment] - Forcing a .war to load after a .ear
Hello,
I had several applications installed in JBoss 4 and had no problems with them.
I had modified deployment sorter to make war file deploy after the
corresponding ear file. For come reasons I need to have the war file outside
the ear file, which only contains .jar files with EJBs. This was no problem for
JBoss 4.
I am trying to migrate to JBoss 5. After some minor changes in code lookup,
they work ok, but I cannot make war's to deploy after .ear when launching JBoss
(When JBoss is runningI touch web.xml and they deploy OK)
I've read in several threads I can use "depends" tag in jboss-web.xml file.
I've done it inserting there the JMX id of some EJBs.
jboss.j2ee:ear=tuportal3.ear,jar=tuportal3.jar,name=PortalManager,service=EJB3
|
Then, I start JBoss and the war actually loads after the ear, but it seems
that the ear is not already fully loaded. I get the following error:
2009-10-25 13:46:36,195 ERROR [com.servengine.util.ServletContextUtils]
(HDScanner) ServletContextUtils: RuntimeException:
| org.jboss.ejb3.common.registrar.spi.NotBoundException: Object is bound at
key
jboss.j2ee:ear=tuportal3.ear,jar=tuportal3.jar,name=PortalManager,service=EJB3,
but is not fully installed, instead of state: controllerst...@1ba6b028{start}
|
The id of the EJB (PortalManager) is right as when deploying the war manually
(touching web.xml) it works ok.
Any ideas about what I am missing?
By the way. I cannot find the .ear it self when browsing jboss.deployment MBean
in JMX Console. I just see an entry for every EJB. Is it possible to refer to
the .ear itself some way in "depends" property in jboss-web.xml so my war does
depend on the .ear and not on a particular EJB(s) in that ear?
thanks for any help

[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Having EntityManagers in different SLSB be "in sync" inside
Hi there, I am having a problem when working with entity managers in different stateless session beans in a same application. I include them via injection: @PersistenceContext(name="myPersistenceContext", unitName="mainPersistenceUnit") | private EntityManager entityManager; | When working inside a transaction, if an entity manager adds or removes entities and before commiting, a method in another session bean ins invoked, even if its entity manager has the same name and unitName, it will not reflect the changes. Is this the right behaviour of entity manager? How am I suppoused then to use only one entity manager or, at least, make these entity manager instances to be consistent with the others? (Of course, not using transactions solves the problem as changes are commited when getting out of every method in the SLSB but I do need transactions here) Thanks, Ignacio View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4196839#4196839 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4196839 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Cascade.REMOVE not working between EJBs in different jars
Hi there, I am having a problem with Hibernate which I don't know if it is a problem or the regular behaviour. Cascade.REMOVE is working fine for me but only between EJBs in the same .JAR (several jars, each for a differente "module" are packed in an .ear for my application) I deploy a .ear file with EJBs grouped in different jars. Some times there are MANY-TO-ONE referentes from EJBs in these different jars. Every thing works OK with these EJBs even they are placed in different jars. My only problem is that removing a EJB will not remove the corresponding side of the relation y the EJB is in another jar file. The only way I have found to solve this is manually adding "on delete cascade" in the MySQL schema, but it is important for me that the database scheme created by JBoss/Hibernate when I deploy de .ear is fully funcional not requiring manual modifications. By the way, should Hibernate add "on delete cascade" constraint when creating the data base schema? It isn't now, but it manages OK cascade removing in EJBs in the same jar anyway. I don't use any Hibernate specific feature. Just EJB3 annotations and I am using JBoss 4 as EJB container.

[jboss-user] [EJB 3.0] - BatchUpdateException when removing a entity with a ManyToMan
Hi there, I am getting BatchUpdateException when removing entities related to others by a ManyToMany association. Hibernate creates the link table with foreign keys and they make that BatchUpdateException to be thrown (I like tables to have foreign keys, of course). I've tried to add a REMOVE cascade, but that makes the end entity to be also removed (for example, removing a UserRole entity removes related User, while only should remove the entry in the intermediate link table. My question is... do I have to remove that relation in target entities before removing the related entity or there is a way to make JBoss/Hibernate to do some intermediate table cascading to remove the relation and avoiding BatchUpdateException?

[jboss-user] [EJB 3.0] - How to get the size of a Lazy load relation
Hi there, I need to pre-load the "size" of a Lazy load relation. I need to do it because I need to access the Entity in a JSP and I get "No session or session closed" if getting the size directly from the relation (I don't want to put a Transaciton using a scriptlet in the JSP page) I can neither do it using PostLoad annotation. It doesn't work at least with JBoss and if I use Eager relations the system loads all data just when checking the size, so becomes very slow. thanks for any help/ideas, Ignacio View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4084999#4084999 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4084999 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Thanks for your reply. I don't use native queries as my components are supposed to work, for example, both with SQLServer and MySQL. I change the mappings in persistence.xml and forget about which data base I am using. One of the reasons to work with all EJB overload is to be able to forget about native queries, isn't it?

Hi there, i have a typical Portal-user-role-component structure, with obvious relations. I have to configure these relations as eager because I need to use entities in the client side (JSP page). My problem is that a very complex and slow query is generated with thousand "combinations" of results, just to load a portal. I've seen that changing eager to lazy in the relations makes the query be much simpler, as lazy relations are not loaded. Can I configure Hibernate / JBoss EJB3 to avoid this complex query.

Is there a way of making JBoss really remove User entities itself without that Hibernate-specific annotation?

Hi there,
thanks a lot for your reply... this is the Portal side:
@OneToMany(mappedBy="portal",fetch=FetchType.LAZY,
cascade={CascadeType.ALL})
| public void setUsers(Set users)
| {
| this.users = users;
| }
|
| @OneToMany(mappedBy="portal",fetch=FetchType.LAZY,
cascade={CascadeType.ALL})
| public Set getUsers()
| {
| return users;
| }
|
and this is the user side:
| @ManyToOne
| public Portal getPortal()
| {
| return portal;
| }
|
| @ManyToOne
| public void setPortal(Portal portal)
| {
| this.portal = portal;
| }
|
Does it look right?

Hi there, I've spent days reading threads and googling about the behaviour of the remove cascade in EJB3 but haven't been able to make Cascade.REMOVE to work in a OneToMany relation. Could anybody post a working example? I have, for example, Portals and Users. I just need that when I do a em.remove(portal), all its users are removed. For the moment I have to remove the child entities myself... and I guess that this should be done by the cascade remove. I am getting that famous "deleted entity passed to persist" exception.

Hi there,
I haven't been able to solve this same problem ("deleted entity passed to

say you just have to "refresh" the parent, but you were saying that you delete
the parent and you expect the children to be deleted. If you delete the parent,
how do you refresh it? (I get "Not managed entity" if I try to em.refresh() it)
Thanks for any help,

[jboss-user] [EJB 3.0] - Re: detached entity passed to persist
I see this is an old thread but just in case someone nees a solution... try to enclose everyting in a UserTransaction. If you take an EJB3 entity outside the transaction, you cannot re-persist it or iterate over CMRs, etc. You need then a UserTransaction in the client side.

[jboss-user] [EJB 3.0] - LazyInitializationException in PostLoad method
Hi, I am getting the following exception when trying to get the size of a one to many relation in a PostLoad method. Of course, this code runs inside a SLSB DAO and should so be inside a transaction: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358) | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350) | at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:97) | at org.hibernate.collection.PersistentSet.size(PersistentSet.java:139) | at com.servengine.contentmanager.CMCategory.postLoad(CMCategory.java:52) I am using Set as the type for the relation and have set Eager load. How am i suppoused to access EJB CMRs from callback methods lik PostLoad?

[jboss-user] [EJB 3.0] - Re: Which approach to fully access EJB3 Entities from within
Just one comment. The only solution I've found is adding @transient properties
to the EJBs with the following structure:
@Transient
| public List getTextblocksList()
| {
| ArrayList list = new ArrayList();
| list.addAll(getTextblocks());
| return list;
| }
|
This way I can get multiple Eager getters for onetomany relations, but makes
JSTL writer need to think if he must use, in this case, ${article.textblocks}
or ${article.textblocksList} depending on if he'll use EL or just regular JSTL
iteration (c:forEach, ...)

[jboss-user] [EJB 3.0] - Which approach to fully access EJB3 Entities from within JSP
Hi there,
after reading lots of posts trying to find a solution to access EJB3 Entity
beans from JSTL I haven't been able to get a valid approach.
I can't use Lazy loading as that would make my JSP need a scriptlet to make a
UserTransaction surround all data access.
When using Eager loading, I have to make all data be returned as Set's, and not
Lists or Collections (solutions for this involve Hibernate specific
annotations, outside EJB 3 standard; I want to stick to EJB3 I've also found
very "ugly" using @IndexColumn or [EMAIL PROTECTED] Hibernate annotations).
As I just said, and because I am using Struts, the only solution I've found is
attaching EJBs in the request/session with there relations as Set types. This
works but I have a big small problem. I can't access data using Expression
Language. For example, I am getting a:
Unable to find a value for "0" in object of class
"org.hibernate.collection.PersistentSet" using operator "[]"
When trying to do:
${newsArticle.textBlocks[0]}
Can anybody thing of an approach to be able to access EJBs in JSP pages without
any limitations, conforming to EJB3 standard and without using scriptlets in my
page? (Of course working with JBoss).
I can't believe that such a simple goal is not actually possible with JBoss
(and maybe other AS's) implementation of EJB3.
Thanks for any help,
Ignacio

[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - How to make a .ear use an expanded war classloader
Hi there, I have the following scenario in my webapps: - .ear file with EJBs (2.1 & 3) - expanded war file with the web interface. I don't include the war in the ear file because in development moment I change many thin in JSPs / struts XMLs /... JBoss configuration What is the ClassLoading configuration to make both the .ear EJBS and the webapp search classes before in /WEB-INF/lib than in the .ear file class loader? I need this because for historical (wrong aprox., of course) reasons, the EJB returns classes that implement some view layer classes, and so I don't want them to be part of the ear file. I have too much code written this way as I used to use Unified Class Loader. My problem now is than I haven't found a way to "mix" both class loaders and so any class retured from the business layer will give ClassNotFound exceptions when used in the presentation layer. (Also, EJB3 POJOs throw ClassCastException). This is solved by packaging the war inside the ear, but I cannot do that. I am changing properties in the following files: 1) conf/jboss-service.xml set NamingService CallByValue to true 2) deploy/ear-deployer.xml set Isolated and CallByValue attributes to true. 3) deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml set Java2ClassLoadingCompliance and UseJBossWebLoader to false 4) /WEB-INF/jboss-web.xml 5) /META-INF/jboss-app.xml Thanks for any help.

[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - NoClassDefFoundError in a expanded war from its own /lib/ ja
Hi there, i am trying tu configure class loading in JBoss 4.0.5 I have an .ear file with and java2ParentDelegation=true I need to access classes in this .ear from my war application, deployed in a war dir (I need to work on it, can't package it in the .ear file) I've tried to reference to the same class loader with jboss-web.xml and tried all combinations of java2ParentDelegation and java2ClassLoadingCompliance flags with no success. The most I've been able to achieve is loding the classes in the ear' jars but classes in /WEB-INF/lib/ jars are then invisible to the webapp (¿?). How can I make the webapp mix both class loaders? Thanks for any help. Please don't point me to those 2 documents about JBoss class loading. I've been reading them for years and, as happens with many JBoss users, can't get a clear picture of all this flags. ¿Any alternative documents about class loading configuration in web apps in JBoss? Thanks for any help until some one writes that pending Web Class Loading WiKi.

[jboss-user] [EJB 3.0] - Setting jndi-name in jboss.xml without ejb-jar.xml
Hi there, as promised for EJB3 I am trying to get rid of ejb-jar.xml. I have a problem when trying to set jndi-name of my EJBs in jboss.xml I deploy the same EJBs in different apps and I used to set different jndi names in 2.1 EJBs in jboss.xml. Doing so I am getting the following error: org.jboss.deployment.DeploymentException: Error in jboss.xml for Bean Annotation: found in jboss.xml but not in ejb-jar.xml do I need a ejb-jar.xml file if I use jboss.xml? I've tried to copy and paste old 2.1 EJBs ejb-jar.xml into my EJB3 ejb-jar.xml, but then jboss understands them as 2.1 EJBs and not EJB3, even setting the correct doctype and xml schema in the ejb-jar file. (Anyway, what I want is not to use at all ejb-jar.xml) Thanks for any help.
