[JBoss JIRA] (CDI-225) Clarify whether bean discovery MAY or MUST NOT include class loading

by Harald Wellmann (JIRA)

Harald Wellmann created CDI-225: ----------------------------------- Summary: Clarify whether bean discovery MAY or MUST NOT include class loading Key: CDI-225 URL: https://issues.jboss.org/browse/CDI-225 Project: CDI Specification Issues Issue Type: Clarification Components: Resolution Affects Versions: 1.1.EDR1 Reporter: Harald Wellmann The CDI 1.0 spec and also the current 1.1 draft is rather vague about the issue of class loading vs. class file byte code scanning for bean discovery. By default, I would assume the term "class" in a specification to refer to a loaded class, unless explicitly stated otherwise. A feature like Seam Solder's {code} @Requires(OptionalDependency.class) public class OptionalBean {code} will necessarily break if the CDI container loads OptionalBean during bean discovery - when OptionalDepencency is not available, OptionalBean cannot be loaded, and the CDI container won't even see the @Requires annotation. See also http://seamframework.org/Seam3/Compatibility, Section Overzealous class scanner. The way I read the CDI spec, GlassFish is fully spec compliant (but maybe not very efficient) in loading bean archive classes for the purpose of discovery. @Requires is also spec compliant, but not portable because it tacitly assumes that classes get scanned but not loaded. So if scanning in place of loading has been a tacit assumption of the CDI 1.0 authors all the time, it should be made explicit in CDI 1.1. Otherwise, if loading is also a valid option, this should be clearly stated so that extension authors will not rely on accidental features of a given CDI implementation. -- This message is automatically generated by JIRA.

[JBoss JIRA] (CDI-229) introduce @OverridesAttribute for @StereoType

by Mark Struberg (JIRA)

Mark Struberg created CDI-229: --------------------------------- Summary: introduce @OverridesAttribute for @StereoType Key: CDI-229 URL: https://issues.jboss.org/browse/CDI-229 Project: CDI Specification Issues Issue Type: Feature Request Components: Beans Affects Versions: 1.1.EDR1 Reporter: Mark Struberg We recently had a thread on the DeltaSpike list about using StereoTypes in real world applications: http://markmail.org/thread/uqozhsix2znwiebn ------ Imagine the following Stereotype for my Services (I spare out the standard stuff) @StereoType @Secured @Transactional @ApplicationScoped public @interface @Service {} The problem here is that there is no way to 'propagate' any rolesAllowed from @Service to @Secured, etc. What I'd like to have is something like ... public @interface @Service { String[] rolesAllowed(); TransactionAttributeType transactionType(); } where the rolesAllowed() would get propagated to the @Secured meta-annotation and transactionType() to the @Transactional ----------- Gerhard Petracek now pointed me to a cool feature which is used in JSR-303 BVAL: @OverridesAttribute http://docs.oracle.com/javaee/6/api/javax/validation/OverridesAttribute.html We should ping the BVAL EG for the details. There are quite a few little tricks and side effects to consider. On the implementation side, we could e.g. pick the @StereoType annotation and automatically propagate those values to the AnnotatedType which get's passed to the Extensions -- This message is automatically generated by JIRA.
