[EJB 3.0] - Entity constraint violation - rollback

by Dens

Hello I'd like to create a method helper on EJB3 entity bean in order to check that a set does not violates any constraint. ex, in acccount class, i create à debit(a) method, implementing it: | public void debit(int a) | if (this.amount>a) { | setAmount(getAmount()-a) | } else { | ????? | } | if this account doesn't have enough money, I'd like to rollback the current transaction, in ejb2 I used setRollBackOnly on the context, I did not find any equivalent. The only solution I found is to throw a runtimexception (dirty solution IMO) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969068#3969068 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3969068

[JBoss Seam] - Re: Can't inject entityManager into application component?

by RobJellinghaus

This is with 1.0.1. Haven't tried @Intercept(ALWAYS) yet. Raja, what do you mean you modified the registration app to do this? That app, in 1.0.1, has no application-scoped components at all. What changes did you make and what components did you add?

[JBoss Portal] - Re: Struts example portlet for 2.4?

by 733nb

I'm also looking for at Struts example. There use to be a struts example under the portal swap, but when that was updated it seem to have disappared. Additionally, in the JBoss Portal 2.4 Reference Guide, under Existing Framework support, you mention "Portlets utilizing Struts". It would be nice to see Struts example in your documentation (user guide) and/or in the portal swap area. We really need this ASAP.

[Clustering/JBoss] - Re: Weird apache behaviour in load-balancing, and form-based

by argaldo

>>> Unless someone in the community who needs it wants to take a shot at it -- hint, hint ;) <<< Got it!! ;-)) I've been digging Tomcat's code and the info to restore the request after the User has been authenticated is stored in a org.apache.catalina.authenticator.SavedRequest object which as you said is not Serializable and it is stored via setNote(Sting,Object) method of org.apache.catalina.session.StandardSession inherited (and implemented) from org.apache.catalina.Session (so, that's not an standard method of javax.servlet.http.HttpSession as you know). A fast peek at JBoss' source code seem to reveal that none of that internal savedrequest notes is neither serialized nor replicated. Will it be worth to give it a try to implement replication of that form-based authentication notes in JBoss clustered sessions? If so, I would be very pleased to do it but also would appreciate some architectural hints to get the job done.

[JBoss Seam] - Re: LIE and accessing collections in next request

by SmokingAPipe

I think what you needed is an extended persistence context. I know that will solve the problem. Could someone give us some idea about when it's ok to use the extended persistence context? Will the system get overloaded if I have a few of them hanging around?

[JBoss Seam] - Annotations for Swing

by SmokingAPipe

This is totally off the topic of Seam, but it's something that Seam users would understand best. Wouldn't it be cool to have annotations when building Swing apps? Instead of doing all these anonymous classes to handle events, you could annotate your bean classes with "inject this UI thing here" annotations. One thing that made me think this is that Trolltech made a version of Qt for Java apps and they are making a big deal of the fact that instead of registering listener objects (ie, anonymous classes) you just call something like register("setName(Ljava/lang/String)") or something. You register the method, not an object. But if you're doing that it's better to use an annotation on the method itself I think. Just my thought of the day.

[EJB 3.0] - Re: executeUpdate and CascadeType issue

by max.andersen＠jboss.com

no it is not a bug. Read the docs about what executeUpdate do and how it works (namely by executing directly on the db and not honoring any cascade or lifecycle's).

[EJB 3.0] - executeUpdate and CascadeType issue

by tzablock

Hi all Here is what I've discovered, maybe it can be considered a bug. I have @OneToMany annotation with CascadeType.ALL attribute specified. If I use EntityManager.remove on the entity everything seems to work fine. If I use Query.executeUpdate delete than the foreign key constraint is violated. The cascade doesn't work.
