[jboss-jira] [JBoss JIRA] (WFLY-7252) war bean not visible for injection

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13301880#comment-13301880 ] 

Stuart Douglas commented on WFLY-7252:
--------------------------------------

Relevant spec sections:

CDI 5.1

"A bean packaged in a certain module is available for injection, lookup and EL resolution to classes and JSP/JSF pages packaged in some other module if and only if the bean class of the bean is required to be accessible to the other module by the class accessibility requirements of the module architecture. In the Java EE module architecture, a bean class is accessible in a module if and only if it is required to be accessible according to the class loading requirements defined by the Java EE platform specification."

>From the Java EE spec EE.8.3.1:

"Components in the web container must not have access to the following classes and resources, unless such classes or resources are covered by one of the rules above.
• Other classes or resources in the application package. For example, the appli- cation should not have access to the classes in application client jar files."

This means that wars cannot see the contents of other wars, and beans deployed in the them are not available for injection outside the war.

> • In an application deployed as an ear, the container searches every bean archive bundled with

> "In the Java EE module architecture, a bean class is accessible in a module if and only if it is required to be accessible according to the class loading requirements defined by the Java EE platform specification."
> But the JavaEE spec states it "may" have access... it did have access on EAP6, does not have access on EAP7.
