[JBoss Seam] - org.jboss.seam.ui.entityConverter not working with set of en

by chandu_great

Hi, The entity converter is not working with a set of entities. I think, the entity converter(org.jboss.seam.ui.entityConverter) doesn't hanlde Set of entities. Its handles only Lists or Collection of entities. In components.xml, I had an entity query(shown below) which was generating a lot of queries. <framework:entity-query scope="EVENT" name="users" ejbql="select u from User u" order="username" /> In User class(User.java) I had a collection of entities defined as protected List roles = new ArrayList(); I changed the semantics from bag/collection to set, that is, protected Set roles = new HashSet(); In order to reduce a number of queries, I tried to use 'left join fetch' query (shown below) which is not working in case of list or collection of entities. But it is working in case of set of entities(:-). <framework:entity-query scope="EVENT" name="usersAdmin" ejbql="SELECT DISTINCT object(u) from User u left join fetch u.groups left join fetch u.roles" order="username" /> Now When I tried to save a record, I am getting conversion error :-(. I checked the entity converter sources. I think the entity converter has no problem working out the value type. In the case of a collection the entity converter must check the type of an item in the value object, rather than the value object itself. I guess that it has code to do this in the case of a list but not a set. Am I thinking right? Any guidance on this issue will be very helpful if someone can throw light on this. Is there any workaround to get rid of this entity conversion problem in case of a set of entities? I am a newbie. Thanks.

[JBoss Seam] - Re: Let's use component scope before lookupInStatefulContext

by dmitriy.lapko

Yes, I thought about this - that such feature can influence outjection. But if I'm sure, that I wouldn't in any place outject any property with name, equal to my component name, I could just specify it in @Name annotation, like: @Name(value = "loginBean", limitSearchByGivenScope="true") So in method lookupInStatefulContext we can check if there is a component with such name and it is marked with a propery 'limitSearchByGivenScope', then it should search only in given scope. If I suppose, that I would use this possibility to overwrite component by outjected object, I would't use this option. Really, I spent last 2 days JProfiling my application and see method getInstance in my hotspots. Too much of calls to method BaseContext.get and ServerConversationContext.isPerNestedConversation...

[JBoss Seam] - Re: Destroying Context Variable

by pete.muir＠jboss.org

I'm pretty sure this works out of the box on Seam 1.2 - I'll check though. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099246#4099246 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4099246

[JBoss Seam] - Re: UrlRewrite and Custom servlets

by pete.muir＠jboss.org

I don't see the context filter in that stack trace - I suspect your urlrewrite filter is causing it not to be applied.

[JBoss Seam] - Re: removing table prefix for generate-entities ?

by luizruiz

You can use a custom ReverseEngineeringStrategy, overriding the tableToClassName or columnToPropertyName methods. Your class can extends org.hibernate.cfg.reveng.DelegatingReverseEngineeringStrategy.

Can we see the whole stack trace for the first two? How much PermGen space are you giving JBoss AS? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099233#4099233 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4099233

eh - it is done per default by our adapter so nothing needed to set it up. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099232#4099232 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4099232

[JBossCache] - Re: writing to JBoss Cache Remotely

by manik.surtani＠jboss.com

No. We don't distribute any code that does this, although creating a wrapper interface to do this using the technology of your choice should be trivial. I know of people who were trying to wrap the cache interface in CORBA so they could write to it from a C app, but that's an extreme case. Another approach would be that your front-end has a Cache instance as well, which is a part of the cluster, but configured to be a "light" member of the cluster (e.g., very aggressive eviction so memory footprint is small; no state transfer; and a clustered cache loader to load state from other cluster members as needed).
