[JBoss Seam] - Re: persist() / remove() at end of long running conversation

by steve.ebersole＠jboss.com

Historically Hibernate would always immediately perform an insert for entities using an IDENTITY based strategy. The reason was that the Hibernate save() method has a distinctly different semantic from persist(); namely save() requires the generated identifier value to be returned as a return value from the save call! persist() is slightly different in that it's declared return type is void, thus the generated identifier does not need to be immediately available upon return from the persist() call. Thus I changed this behavior starting in 3.2 such that the insertion to generate and obtain the identifier value is delayed until a flush. However, that only occurs when we are outside a transaction. This should probably be extended such that we also delay in the case of FlushMode.MANUAL as well. This should be easy to verify. Have a look at org.hibernate.event.def.AbstractSaveEventListener#performSaveOrReplicate. Specifically the part about 'shouldDelayIdentityInserts'. Currently, that is set via: | boolean shouldDelayIdentityInserts = !inTxn && !requiresImmediateIdAccess; | Try changing that to: | boolean shouldDelayIdentityInserts = !requiresImmediateIdAccess && | ( !inTxn || FlushMode.isManualFlushMode( source.getFlushMode() ) ); | Let me know how it goes at : http://opensource.atlassian.com/projects/hibernate/browse/HHH-2439 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020832#4020832 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4020832

[Performance Tuning] - Re: Number of webcontainer threads and connection pools used

by PeterJ

You are mostly correct (well, as far as I know, I would have to dig through the source code to verify the exact usage), except that MaxConnectionsInUseCount is the maximum number of connections that were ever allocated since the app server started.

[Beginners Corner] - Re: A new understanding of ClassLoaders...

by PeterJ

Sorry, but without knowing more details about the relationships among your classes in the various jar files, I really cannot answer your last question. There is something you might try to learn a little more about what is going on: start the JVM passing it the -verbose:class option. This causes the JVM to state where it found each class. Sometimes looking that this output clears up what is going on, especially if you see a class being loaded from an unexpected location.

[JBoss Seam] - Entity relations with metadata

by MikeDougherty

Hello all, I have a number of entities that relate to each other via a join table. So far the @Entity objects have mapped pretty well with @JoinTable/@JoinColumn. However, there is more data in the join table than just the id's of the entities it joins, such as EffectiveDate, EndDate, ModifiedDate, etc. There are also different join tables for each association (i.e. ENTITY_A_B_JOIN, ENTITY_B_C_JOIN, etc). The easiest solution would very likely be to create an Association superclass and subclass for each join I need to make. But I would like to challenge myself a little more and see if there is a Cool Seam way of solving the problem. Maybe using a combination of components.xml, injecting, and a generic class to come up with the solution. I haven't seen anything in the documentation that stands out as "the way" to do this. But maybe someone out there has done something similar and wouldn't mind pointing me to the appropriate features of Seam that will get me going in the right direction. Mind you, I'm not asking you to do my work for me, just point me to the sets of features, and creative uses thereof that will get me going. Thanks.

[JBoss Portal] - Re: Single Sign On with Alfresco Portlet

by sohil.shah＠jboss.com

Portlets receive the same authenticated state that you get when you create an authenticated session when logging into the Portal So all you have to do is login to your portal, and the Alfresco portlet running inside this portal will be in this authenticated state (authenticated state = Principal object with its proper roles etc) Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020826#4020826 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4020826

[JBoss Seam] - Re: Seam Email - IllegalStateException: No Factories configu

by petemuir

The only reason I ask for a seam-gen based project is that it comes with a build.xml/structure I'm familiar with hence reducing the complexity for me. I'm not going to ask you to send your whole project through as it would takes days to understand it. I'm pretty sure (as are you I think) the problem is to do with your project structure so you could (a) strip a copy of your project removing everything that is irrelevant or (b) try to replicate in another project (e.g. a seam-gen one or the mail example). Sorry, I'm not telepathic (I wish I was ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020823#4020823 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4020823

[JBossWS] - Re: NoSuchMethodError on TypeBinding.setBeforeMarshallingCal

by joshlam

My mistake. I solved the problem, I really should use: AddressContactMethod a = (AddressContactMethod)call.invoke(new Object[]{addr}); instead of | StandardizeAddressResponse ctr = (StandardizeAddressResponse) call.invoke(new Object[]{stdAddr}) Sorry about that, I am still learning ...

[Messaging, JMS & JBossMQ] - Re: MDB's activated too early

by josey

You can make the MDB depend upon that which must be deployed before the MDB is deployed. This can be set using the @Depends class-level annotation. For example, if there are two session beans that must be deployed prior to the MDB then add the following annotation. | @Depends({ | "jboss.j2ee:ear=myEar.ear,jar=myJarFile.jar,name=MySessionBean1,service=EJB3", | "jboss.j2ee:ear=myEar.ear,jar=myJarFile.jar,name=MySessionBean2,service=EJB3" | }) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020820#4020820 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4020820

[JBoss Portal] - Single Sign On with Alfresco Portlet

by NewTo23

Hi, I have deployed the Alfresco 1.4 portlet in my JBoss portal server 2.4.1 Please provide me with some inputs on how I can achieve Single Sign On between the Alfresco portlet and my JBoss portal server.

[JBoss Seam] - Re: JDBC error in Factory class

by james_hays＠mac.com

"petemuir" wrote : It's likely there is another exception occuring earlier which is the root cause of the problem. What is the best way to help in determining this? I too have this issue quite frequently and am having limited success in tracking down the issues. Often times, I see this issue pop up after several queries have run, but it gets to a specific outjection that blows up. Is seam eating all of the exceptions? It appears that if something goes wrong in the application this GenericJDBC exception is thrown regardless of cause.
