[EJB 3.0] - Re: Detach entities - Obtaining a clear pojo

by fatbatman

I also need to obtain a completely clean Pojo. I currently serialise detached entities then send them over a network to a remote client which is an applet that has no concept of EJB3 (no ejb jars on classpath). Here the client treats them as Pojos. When running a full round trip unit test in which a detached obj is sent to the client, if a field/association is not initialised then I want a null value, not a LazyInitialisationException. But because in the test case the client and server are both run within the same JVM I get a LazyInitialisationException. If I was able to get a completely clean Pojo, this wouldn't happen. Is there some standard way of doing this? like a; Object getCompletelyDetachedClone(obj) method? thanks in advance James View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969090#3969090 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3969090

[EJB 3.0] - Re: JbossQL and m.createQuery(.. OFFSET 5 LIMIT 23)

by laszlo.fogas

ok I was wrong: It generates the desired offset/limit queries unless you use join fetch in your query to initialize lazy collections. In the docs: (http://docs.jboss.org/ejb3/app-server/HibernateEntityManager/reference/en...) "Nor should fetch be used together with setMaxResults() or setFirstResult(). It is possible to create a cartesian product by join fetching more than one collection in a query (as in the example above), be careful the result of this product isn't bigger than you expect. Join fetching multiple collection roles also sometimes gives unexpected results for bag mappings, so be careful about how you formulate your queries in this case. TODO: The last statement is useless and typical developer thinking, please elaborate. The word "sometimes" should never appear in any technical documentation." funny :) So what is the status of this problem(?) now? I know the collection.size() workaround, but i don't like it!! I think that solution is much slower. Is there other solution? lazlo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969089#3969089 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3969089

[EJB 3.0] - Re: JbossQL and m.createQuery(.. OFFSET 5 LIMIT 23)

by laszlo.fogas

Hi, I found the same solution, but when i examined a bit more i realized that the whole resultset is generated every time, and these methods only cut a part of that. It does not generate offset/limit like sql query. Am I right? Because it could cause some performance problems.

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

by raja05

I got this working after a lot of reverse engineering. Anyway, the secret was that the method starting the conversation had to somehow call the responseComplete method(by having an outcome) and then the conversation was carried between screens. In my case, since it was a factory and nothing was returned from there, the conversation was killed soon after it was started.

[JBoss Seam] - ConversationEntry -- Should lastRequestTime equal startTime

by raja05

When a conversation is created, the ConversationEntry object has the starttime equal to the current time and the lastRequesttime set to 0. Should the lastRequestTime be also initialized to the current time stamp? Here is why Im asking this. In my application, I start a conversation on a Stateful bean and all Im doing there is displaying the view. A ConversationEntry is created at this point of time. The view has a #{categories} which is a @Factory and it initializes the categories Array. The problem is that this variable(and the rest of them) are not stored during the next request in the conversation. This is because the afterPhase calls Manager.instance().conversationTimeout after the view is rendered and this basically deletes the conversationentry. The logic to delete the conversationentry works for a regular timeout but in this case, the conversation creation has just happened(during the render response phase). If we set the lastREquestTime to be the same as the current time, then the difference(currentime - lastRequesttime) will be less than the conversation timeout and the entry will not be deleted. im not sure if im explaining my case clearly, but if its not, please ask me for more information.

[JBoss jBPM] - Better understanding of the starter kit

by zilber

In order to learn JBPM I read the tutorial, and also installed the starter kit. I ran it and it worked very nice. I then tried to understand how it works under the hood, and I wonder if there's any documentation that explains things like: Why does the kit consist of a service and an application? is it best practice to have both? how do the sar and war integrate? And what is the role of the JbpmThreadsServlets that gets loaded by the starter kit application? And why does the app use deprecated API (JbpmContext.getCurrentJbpmContext())? As you see, I have many questions, all of which deal with the best way to integrate JBPM and JBoss. Are there pointers to answers? Thank you in advance.
