[EJB 3.0] - Re: @NamedQuery and setting orderBy as a parameter?

by mazz＠jboss.com

> Query q = em.createNamedQuery(findHottestContent + " order by viewsWeekly desc"); that doesn't work!! That's not a named query. This is a very big thing missing in the spec, this much is clear.

[JBoss Seam] - Re: MC/Seam integration and unification

by bill.burke＠jboss.com

anonymous wrote : I know that 1) can be done easily enough. Trouble is that it makes Seam more difficult to learn and to support. Really, how so? Package format would remain the same as it currently is, except bootstrap and config of bootstrap is the same as embedded jboss, jboss. Again, the end goal being that all our projects/products are configured, deployed, bootstrapped and installed the same way or as similar as possible. anonymous wrote : Regarding hotdeploy, I may be wrong I don't see how that can ever work for the *individual Seam components*. However, larger units such as EJB jars and WARs should support hotdeploy, but that does not really require changes to Seam. I highly doubt there won't be configuration requirements... I looked at your code and what you're doing deployment wise is *exactly* the same as what the kernel does except it is solely specific to Seam, minus the flexility. MC/kernel gives an abstraction for deployment so that things like management can be snapped on later. Deployment has changed radically in JBoss 5. In the old kernel, there was a one to one relationship between deployer and archive. In JBoss 5 kernel, each deployer has a chance to look at and process each archive. Some of the things Scott is architecting into the ProfileService will allow deployers to serialize/most of their metadata so that the next time the app server is booted up (or the WAR redeployed) deployment is a lot faster as you can skip the metadata phase and just focus on binding. Not only that, but a lot of thought has been put into how things could be configured through IDEs and such.

[EJB 3.0] - Re: ServiceLocator pattern - delegates in the context of EJB

by javaneze

Thank you for your replies! The need of service locator was to hide the multiple JNDI calles and in EJB2.x to cache the interfaces so that you would not have to 'ask' it every time you need a common used EJB reference. I am bit confused how we can achieve this kind of caching! or maybe is this caching necessary in EJB3 or the container now does greater magic..trying to optimize the whole thing! I know service locator is not rocket science my app now runs perfect with plain JNDI calls..though I come from a EJb2.x background and it used to be a heavily used pattern..

[Beginners Corner] - Content appearing in wrong place

by cesarsaxy

Hy, everybody! I am installing a new site with JBoss Portal and I´ve been strugling w/ a problem: my page has a portlet at its left with some links, and another portlet at its center with a CMS Portlet designed to receive the content regarding to these links (some htmls files inserted in the CMS). But when I click in these links, their contents appear in another portal called "default" inside a portlet called DefaultCMSPortlet (it comes w/ the default installation of JBoss Portal) How do I proceed to make the contents of these links appear in the center of the portal that I´ve just created? Is it possible to do that using the management interface? Or must I edit some config file? In this case, which file?

[JBossCache] - Re: when eviction is configured in the clustered environment

by bstansberry＠jboss.com

This is a bug -- http://jira.jboss.com/jira/browse/JBCACHE-963 . Thanks for reporting it. If Tomcat undeploys webapps as part of normal shutdown (not sure if it does -- JBoss AS definitely does), the workaround is to ensure that your webapp calls cache.stopService() as part of undeploy. You should do that anyway.

[JBoss jBPM] - Re: jBPM and Message Driven Beans

by estaub

@gforam, For now, if I were you I'd try @new4jboss's save-and-reload hack. You haven't already, right? I think I've managed to raise a little concern about this problem at jboss.com - the timing-dependent nature makes it a real support headache that they shouldn't want. Stay tuned... -Ed Staub (newbie) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008985#4008985 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4008985

[JCA/JBoss] - Re: Oracle Connection -- WrappedConnection -- CastException

by weston.price＠jboss.com

When you say application lib, I assume you mean your deployment archive right, or do you mean in your server/lib directory? The reason I ask is that there are significant Classloader issues when attempting to include your JDBC driver inside of your EAR/WAR etc. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008982#4008982 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4008982
