[JBoss Seam] - Injection and relation between components
by rmemoria
Hi all,
I'm using JBOSS 4.0.5 and SEAM 1.2.1
I don't know if it's a bug or my (wrong) way of using components.
I have a long running conversation and a java bean component declared like this:
@Name("drugOrderHome")
| public class DrugOrderHome extends EntityHome<DrugOrder>{
| private static final long serialVersionUID = 2666375478687085792L;
|
| @In(create=true)
| private SourceConsumptionHome sourceConsumptionHome;
this entityHome component remains in memory until the end of the conversation. And there are several requests during the conversation .
PROBLEM: The state of the component injected (sourceConsumptionHome) is lost between every request inside the long running conversation, while the DrugOrderHome component remains intact.
Is this a feature or a bug? Is there a way of preserving the state of the injected component?
Regards,
Ricardo Memória

[JBoss Seam] - Re: Trouble Using <s:convertEntity/> on Glassfish
by soluble
Thanks for the clarification. Seam really does have some neat features!
I am trying to get to the root of my problem so have reverted to using the "jboss-seam-1.2.1.GA/examples/glassfish" example. I tried adding <core:entity-manager-factory name="dbFactory" persistence-unit-name="bookingDatabase"/> to the components.xml file expecting the example app to still work. However I got the following error:
| javax.persistence.PersistenceException: java.lang.NullPointerException
| at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:252)
| at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:120)
| at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:96)
| at org.jboss.seam.core.EntityManagerFactory.startup(EntityManagerFactory.java:74)
| at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
| ...
|
Does anyone know what config I should tweak to get the entity-manager-factory working on the glassfish example? I suspect it is a visibility problem with the persistence.xml file and associated entities. However, it is late and I would like to stop experimenting for the night. Maybe once that works, I can try thinking about <s:convertEntity/> again. ;)

[Tomcat, HTTPD, Servlets & JSP] - JSF 1.1 RI + JSTL + JBoss doesn't work
by pjsa
Hi JBoss Community!
I developed an application (using Netbeans 5.5 with Sun AS 9.0) that uses following technologies:
- Database
MySQL 5.0
- Persistence
JPA
- Business Layer
EJB 3.0
- Web
Servlet
JSP with JSTL 1.1
JSF 1.1
Everything work fine in my development environment, but the production environment uses JBoss 4.05 GA. I confess: I'm newbie with JBoss and I am having many problems to deploy my application in this server. Lets go to the issues:
1- JSF doesn't work
When I used My Faces (already installed in the server), JSF page worked, but layout was corrupted. So, I tried use JSF RI 1.1 (as in my development environment). For it:
- I deleted jsf-lib directory
- I upload jsf-api.jar and jsf-impl (and dependencies) to
<jboss home>/server/default/deploy/jbossweb-tomcat55.sar/ (because I want the .ear be small)
- I modified <jboss home>/server/default/deploy/jbossweb-tomcat55.sar/conf/web.xml, commenting the part below:
<init-param>
<param-name>engineOptionsClass</param-name>
<param-value>
org.jboss.web.tomcat.tc5.jasper.JspServletOptions
</param-value>
</init-param>
Specify the jars relative to the jbossweb-tomcat55.sar that should
be scanned for common tag lib descriptors to include in every war
deployment.
<init-param>
MyFaces tlds
<param-name>tagLibJar0</param-name>
<param-value>jsf-libs/myfaces-impl.jar</param-value>
</init-param>
And finally, I cleaned work and tmp directories. After it, I restart JBoss, but when I test the application, I get the following error:
java.lang.NoClassDefFoundError: org.apache.myfaces.taglib.core.ViewTag

2- JSTL Expression Language are not been interpreted
Code like this:
<c:forEach items="${sessionScope.news}" var="item">
<a href="/sivople/views/apps/noticias/lerNoticia.jsp?noticia=<c:out value='${item.contentUrl}' />"> <c:out value="${item.title}" />
</c:forEach>
is rendering as below:
${item.title}
In this case, there isn't errors in the log.
Any sugestions?
