[JBoss Seam] - Stateless vs Stateful Bean
by Delphi's Ghost
Now my understanding of stateful vs Stateless session beans is that stateful ones contain state, and stateless beans don't, and are just worker beans that perform tasks.
However, Seam kind of blurs the lines between the two since any state can be held outside the bean as a context variable and in/outjected as needed.
A search screen may have a criteria object for holding search params, and a result list. You can biject both these items into the search bean and have it as a stateless bean, or you can make the results and the criteria accessible only as members of a stateful bean. Ignore for now the issue of injecting an extended persistence context into the stateless bean (we can use a Seam managed PC)
If I understand it correctly, a stateless bean may only have a few instances shared by multiple users (depending on the container implementation) since it carries no state, while a stateful bean is a 'one per user' bean.
Looking from a memory use perspective. A stateful bean only ever needs 1 string for the variable name, and one pointer for the reference to the bean. Stateless beans with bijected state require one string, and one pointer per bijected member.
I seem to recall reading that it was unwise to use bijection excessively, especially in a clustered environment which would be a plus in the stateful bean column (however, I can't find that comment now in the seam docs). The documents also warn about binding an entity bean to a conversational or session scoped seam context variable, opting to hold a reference to it in the stateful session bean instead.
So the question is, is it better to biject state, or is there value in holding state in a stateful bean?

[JNDI/Naming/Network] - Re: JNDI Look up in JBoss 4.0.5GA
by itsme
as your jndiView states different local interfaces should be located right in the GlobalNameSpace. So they should be looked up via
new InitialContext().lookup(<InterfaceName>);.
Besides that there are some ejb's bound to ejb/, so ejb/ should be used for lookup code.
As far as I can see from your JndiTrace it should be possible to retrieve the home interface like this (i.e. for SessionMaterial found here
anonymous wrote :
| +- UILConnectionFactory[link -> ConnectionFactory] (class: javax.naming.LinkRef)
| +- ejb (class: org.jnp.interfaces.NamingContext)
| | +- SessionMaterial (proxy: $Proxy76 implements interface com.skandia.model.session.material.SessionMaterialHome,interface javax.ejb.Handle)
| | +- SessionCodes (proxy: $Proxy74 implements interface com.skandia.model.session.codes.SessionCodesHome,interface javax.ejb.Handle)

| ...
| Object obj = ictx.loopup("ejb/SessionMaterial");
| SessionMaterialHome home = PortableRemoteObject.narrow(obj, SessionMaterialHome.class);
| SessionMaterial ejb = home.create();

[Installation, Configuration & Deployment] - Could not destroy component - NoClassDefFoundError: com/sun/
by jcg3
Hello everyone--
I have an odd exception being thrown in my application... but first, here's what I'm running.
- JBoss 4.2.0.GA
- Seam 1.2.1.GA
I have followed the instructions to run Seam on JBoss 4.2 (changes to web.xml, application.xml), and everything works fine. The usage of expression language works, and I'm not having any problems with my application's main functionality.
The exception (full stack trace below) occurs when my session beans expire and the server tries to run the destroy method... I'm not clicking on any webpages to trigger this functionality, it just occurs when I leave my server running idle after running through some testing.
This doesn't seem to be caused by different timeouts between my HTTP Session and my EJBs, which is the only real reference to this type of error that I was able to find in existing docs/forums. Also, I can post this to the Seam forum, but I am guessing this is a configuration issue.
I can certainly ignore the error messages as it doesn't impact any functionality, but I figured someone might be able to point me to a solution so I don't clutter up my log files.
Thanks in advance,
Jason

[JBoss Seam] - No active transaction after validation exception
by shakenbrain
I have a validator class in Seam 1.2.1; I'm using JBoss AS 4.0.2.
@Validator
| @Name("prefixValidator")
| public class PrefixValidator extends BaseValidator {
|
| @In
| EntityManager entityManager;
|
| @Transactional
| public void validate(FacesContext context, UIComponent component, Object value)
| throws ValidatorException {
|
| entityManager.joinTransaction();
|
| String prefix = (String) value;
| Query q = entityManager.createQuery("from Organization o where o.prefix = :prefix");
| q.setParameter("prefix", prefix.toUpperCase());
| if (q.getResultList().size() > 0) {
| throw new ValidatorException(makeMessage("Prefix is being used already"));
| }
| }
| }
If the validation occurs as the result of an ajax4jsf partial submit (onblur) everything works fine:
<s:decorate id="prefixDecorator" template="/decorateField.xhtml">
| <ui:define name="label">Prefix</ui:define>
| <h:inputText id="prefix" size="4" value="#{selectedOrganization.prefix}" required="true" disabled="#{!organizationAdmin.new}">
| <f:validator validatorId="prefixValidator"/>
| <a:support event="onblur" reRender="prefixDecorator" oncomplete="this.value=this.value.toUpperCase()"/>
| </h:inputText>
| </s:decorate>
|
However, everything falls apart when I take out the <a:support> tag (causing the validation to occur when the whole form is submitted). It appears that the transaction ends or is lost. Any idea why that might be happening?
<s:decorate id="prefixDecorator" template="/decorateField.xhtml">
| <ui:define name="label">Prefix</ui:define>
| <h:inputText id="prefix" size="4" value="#{selectedOrganization.prefix}" required="true" disabled="#{!organizationAdmin.new}">
| <f:validator validatorId="prefixValidator"/>
| </h:inputText>
| </s:decorate>
The validator fires, throws its validation failed exception (good), and then it appears that the transaction is lost when re-rendering the page. Here's the log:
