Wrong beanmanager retrieved by CDI.current().getBeanManager() in Struts1
by Eric B
I'm running into a really strange behaviour, and I'm not entirely sure
where/how to start looking for this or if it is something that I can easily
reproduce in a test case (or if it is even worthwhile).
I've got a mutil-war JEE EAR application that uses EJBs, Struts1. and
Struts2.
My EAR is as follows:
EAR
- root.war
- ejb.jar
- web.war
- ws.war
- lib/common jars
In one of my war1 web filters, I am sucessfully able to retrieve a bean
from the CDI using:
SessionManager sessionManager =
CDI.current().select(SessionManager.class).get()
However, in a Struts1 action, I'm trying to retrieve the same bean from the
CDI using:
SessionManager sessionManager =
CDI.current().select(SessionManager.class).get()
but WELD throws and error that it is unable to resolve the SessionManager
bean:
org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001308:
Unable to resolve any beans for Type: interface
webapp.session.SessionManager; Qualifiers: []
When I dig more into it, I see that CDI.current().getBeanManager() in the
filter always returns the beanManager for my ear/web.war deployment.
However, when trying the same call in my Struts 1 Action, instead, it will
at times retrieve the bean manager for other deployments, seemingly
randomly:
- ear/root.war
- ear/ws.war
- ear/ejb.jar
- ear/web.war
If I retrieve the BeanManager manually from the JNDI, using a JNDI lookup,
I am able to retrieve the bean without problems:
BeanManager beanManager = (BeanManager) new
InitialContext().lookup("java:comp/BeanManager");
Set<Bean<?>> beans = beanManager.getBeans(SessionManager.class);
Bean<?> bean = beanManager.resolve(beans);
CreationalContext<?> context = beanManager.createCreationalContext(bean);
SessionManager sessionManager = (SessionManager)
beanManager.getReference(bean, SessionManager.class, context);
So at the end, I'm not entirely sure why CDI.current().getBeanManager()
would be retrieving the BeanManager from a different context. Might this
be a bug in Weld, a problem in the container, or something strange that is
happening due to the way that Struts1 was designed? Or do I need to do/add
something specific to a config to enable CDI access from within a servlet?
Struts1 is launched as a servlet in the web.xml:
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>chainConfig</param-name>
<param-value>/WEB-INF/chain-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Thanks!

Upgrading Bean Validation and Hibernate Validator in WildFly 12
by Guillaume Smet
Hi everyone,
(posted with the wrong address a few days ago and then stuck in the
moderation queue, please discard the one in the moderation queue)
As mentioned by Gunnar in a previous thread, we would like to upgrade Bean
Validation and Hibernate Validator in WildFly 12.
I created a PR before the holidays:
https://issues.jboss.org/browse/WFLY-9615
(there are some test failures on Linux but I don't think they are related
to the PR as the other builds are passing)
BV 2.0 and HV 6.0 are highly compatible with the previous versions: we
removed a few advanced features marked as experimental as they have now
been included in Bean Validation in another form, but, apart from that, the
upgrade should go smoothly for the users.
We have released HV 6.0 at the beginning of August and it has matured since
then (we are at 6.0.7.Final).
Our migration guide is here: https://developer.jboss.org/wiki/
HibernateValidatorMigrationGuide .
Two important things to note:
- the groupId of Hibernate Validator has changed: it was org.hibernate, it
is now org.hibernate.validator. I added the according banned dependencies
in WildFly to be sure we don't ship both;
- in 6.0.6.Final, we reintroduced some API/configuration knobs that were
removed in prior versions of 6.0. We deprecated them in 5.4 but as WildFly
has never shipped 5.4, we thought it was better to keep them for 6.0 and
remove them later (so that we have at least once WildFly version with the
deprecation).
Apart from the new features brought by Bean Validation 2.0, we worked on
reducing the memory footprint of HV and improving the performances so it
would be nice to bring all that to our WildFly users.
Feedback welcome.
