Mark,
Thank you for the response.
1. Yes, I did add an 'empty' beans.xml to WEB-INF as advised by many places
on the internet, and the app starts up successfully. I did 'not' have
beans.xml added to META-INF, since all of my code is in the web app (I
created no JARs of my own). I just added beans.xml to META-INF (while
beans.xhtml already exists in WEB-INF), attempted to start glassfish, and I
get the following error:
INFO: WELD-000900 1.1.8 (Final)
SEVERE: Exception while invoking class org.glassfish.weld.WeldDeployer load
method
java.lang.NullPointerException
at
org.glassfish.weld.BeanDeploymentArchiveImpl.handleEntry(BeanDeploymentArchiveImpl.java:504)
at
org.glassfish.weld.BeanDeploymentArchiveImpl.collectJarInfo(BeanDeploymentArchiveImpl.java:482)
at
org.glassfish.weld.BeanDeploymentArchiveImpl.populate(BeanDeploymentArchiveImpl.java:422)
I'm sure the error above means that my web app does not need 'empty'
beans.xml in META-INF (and WEB-INF), so I will remove beans.xml from
META-INF.
2. Yes, all CDI beans (accessed via EL) have @Named annotation, and I am
using @Inject along with Qualifiers (for classes that extend ancestor
classes). Below are notes from what I did/completed yesterday for this
migration:
Migrate from JSF Managed Beans to CDI Managed Beans
Replace
javax.faces.bean.ManagedBean
with
javax.inject.Named
replace
javax.faces.bean.ManagedProperty
with
javax.inject.Inject
replace
javax.faces.bean.SessionScoped
with
javax.enterprise.context.SessionScoped
replace
javax.faces.bean.ApplicationScoped
with
javax.enterprise.context.ApplicationScoped
replace
@ManagedBean(name =
with
@Named(
replace
@ManagedProperty("#{.*}")
with
@Inject
Migrated applicationScopeBean from JSF ApplicationScoped managed bean to
EJB @Singleton with @Startup (*please disregard this*, since the last thing
I did with this was to migrate it to CDI applicationscoped instead of EJB
singleton and startup)
Added CDI Qualifier called @Descendant for all descendants of Address,
EmailAddress, Phone, and PointOfContact controllers
Replace
FacesContext.getCurrentInstance().getExternalContext().getSessionMap()
with @Inject and private instance variable
3. Honestly, I was hoping not to have to migrate to another container like
Tomcat or TomEE, since I only have little/limited experience with those
containers (as I attempted to migrate to Tomcat 7.0.32, 1 or 2 weeks ago,
but too much was involved and I couldn't even get the web app to start). I
am open to trying TomEE, hopefully, as a last-and-final option. :)
