[JBoss Seam] - s:link propagation
by trickyvail
When you use a s:link tag the tag propagates long-running conversations by default. You can change it's behavior with the use of the propagation attribute:
anonymous wrote : propagation - determines the conversation propagation style: begin, join, nest, none or end.
Shouldn't there also be a propagation attribute value for the default behavior? Something like propagation="propagate".
>From what I can understand the jsf tag libs and ejb3 annotations are structured in this manner. If you don't specify (or annotate) an attribute (or field / method) the defaults take precedence. However you have the option of being literal and specifying the attribute or annotation - including literally specifying the default.
If you take a look at this previous post http://www.jboss.com/index.html?module=bb&op=viewtopic&t=118268 I think you might get an idea why this could be useful. Currently I have to create duplicate s:link tags to get around this limitation.
Thanks for you insight and comments.

[Persistence, JBoss/CMP, Hibernate, Database] - second level cache
by loic
Hi All,
I'm using EJB3 on jboss4.0.5.GA connected on MSSQLServer using jtds.
Everything's going well instead a problem on cache.
Here is the test i'm doing :
I have a sample entity :
@Entity
| @Table(name="FileToSend")
| public class FileToSend
And i'm using it in a stateful session bean where I use a fonction to test cache
| @Stateful
| public class FileToSendBean implements RemoteFileToSend
|
public void findAll() {
| // TODO Auto-generated method stub
| for(int i=0;i<6;i++){
| em.createQuery("SELECT c FROM FileToSend c").getResultList();
| }
| }
I am calling it threw a fonction in a servlet :
ctx = new InitialContext();
| fileToSendService= (RemoteFileToSend) ctx.lookup("FileToSendBean/remote");
|
| for(int i=0;i<6;i++){
| fileToSendService.findAll();
| }
Each call to the findAll fonction is well done and i get the results each time.
But The matter that i have is that the request is processed each time on SQL Server.
I think if i'm not crazy that launching several times the same query doesn't need to get the information in SQL server but in the cache, isn't it?
So I think I'm missing something... please help!!
Here is the log i got when starting my ejb ... all seems well to me.. and second level cache is enable :
