[Installation, Configuration & Deployment] - Need JBoss consultant in Denver area

by david＠windward.net

Hi; We need a JBoss consultant in the Denver area to walk us through the best way to install JBoss and get a simple servlet running on it. And the best way to get a database connection. This should be a 3 - 6 hour job at most as what we need is very straightforward - the trick is knowing what to do. thanks - dave david(a)windward.net 303-499-2544 x1185 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3970612#3970612 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3970612

by perrucci

Thank you Alex, I'm trying to build the latest version but the svn url doens't work. I found the same url here http://wiki.jboss.org/wiki/Wiki.jsp?page=JEMSInstaller so I think there is a problem on svn. Can you confirm the problem?

[EJB 3.0] - Re: deleting entities from a Collection

by laszlo.fogas

define a hibernate specific annotation, because this kind of deleting ejb3 spec does not support. In hibernate it's delete_orphan cascade type.. use | @OneToMany(fetch = FetchType.LAZY, mappedBy = "felhasznalok") | @org.hibernate.annotations.Cascade( { | org.hibernate.annotations.CascadeType.ALL, | org.hibernate.annotations.CascadeType.DELETE_ORPHAN }) | public Set<Kedvencek> getKedvenceks() { | return this.kedvenceks; | } | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3970610#3970610 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3970610

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

by laszlo.fogas

ok, i try again :) So, i have an object with lots of lazy onetomany relations. I have second level cache enabled(TreeCache). I would like to use pagination with the setfirstresult/maxresult methods. If i initialize the lazy collections with calling the size method, and use pagination the entity manager generates the limit/offset into the sql query. (i set the a show sql param to true.) But this way the cache does not operate as good as i expect: It's slower than dbhitting. Here comes the sopution: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=88317 Which says that i should use fetching joins to initialize the collections, because the implementation likes that much more.. OK i did this. But than the pagination breaks.. there's no limit and offset in my queries. The documentation has a funny comment on this: "Note that the fetch construct may not be used in queries called using scroll() or iterate(). Nor should fetch be used together with setMaxResults() or setFirstResult(). " What does this mean? Noone faced the same problem before me? I have tested the cache with the fetching joins: i changed my query (id<10) in order to simulate the case with limit 10 to test the speed.. As the link said the cache working fine.. the query speed decreased after the first loading. So there are two bugs(?) which prevent me to use EJB3 efficently!! Any slutions? Workarounds? regards, Lazlo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3970607#3970607 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3970607

[EJB 3.0] - Re: How to avoid specific Hibernate config in EJB3 source co

by max.andersen＠jboss.com

they are only needed at compile time, not at run time. if you don't want mapping details in source code use jpa xml overriding or hbm.xml's.

[JBoss Seam] - Re: Interface from C app to Seam?

by chuaky

Thanks Raja for the advice. I'm building a web app using seam + portal + facelets, so i wanted the C app to interface with the java beans written in seam. Sorry, i'm a newbie so some of the terms may be incorrectly used. Cheers.

[JBoss Seam] - Multiple roles and accessing the DataModel

by zzzz8

I'd like access a JSF DataModel from my JSP using EL. Normally, this is a very easy thing to when one doesn't use multiple roles. But in this case, I'm assigning multiple roles to a component and I can't seem to figure out the correct syntax for accessing the DataModel. For example, here's a snippet of my source code: @Name("component1") | @Role(name="component2") | @Stateful | public class Test implements TestLocal { | @DataModel | List<Item> list; | | @DataModelSelection | Item item; | } What is the correct EL for accessing the DataModel list associated with the component1 role and the component2 role? I've tried: #{component1.list} | #{component2.list} However, when I do this, I don't seem to be getting the DataModel, but rather the actual List itself. This is evidenced by the fact that a method in the class that uses the DataModelSelection is always stuck at pointing to the first item in the List list... I've also tried modifying the source code to annotate with DataModel on the getter method: List<Item> list; | | @DataModel | public List<Item> getList() { | return list; | } Also, is there a bug with using the DataModelSelection and DataModelSelectionIndex annotations in the same class?
