[JBoss JIRA] (CDI-533) Bean Deployment archive conflicts between section 5 and section 12
by Jozef Hartinger (JIRA)
[ https://issues.jboss.org/browse/CDI-533?page=com.atlassian.jira.plugin.sy... ]
Jozef Hartinger commented on CDI-533:
-------------------------------------
I don't think there is a conflict actually:
Section 5.1 says:
{quote}
Beans and their clients may be deployed in modules in a module architecture such as the Java EE environment. In a module architecture, certain modules are considered bean archives. In the Java EE module architecture, any Java EE module or library is a module. The Java EE module or library is a bean archive if it contains a beans.xml file.
{quote}
It basically says that a bean archive is either a Java EE module or a library jar.
Let's use an example
{noformat}
app.ear
|-- web1.war
| |-- WEB-INF/classes
| |-- WEB-INF/lib
| |-- weblib1.jar
| |-- weblib2.jar
|-- ejb1.jar
|-- lib/
| |-- earlib1.jar
{noformat}
According to section 5.1 we (possibly) have the following bean archives:
* web1.war and ejb1.jar which are modules
* weblib1.jar, weblib2.jar and earlib1.jar are library jars
On top of 5.1, section 12.1 defines what it means for a module to be a bean archive. More specifically it says:
{quote}
When determining which archives are bean archives, the container must consider:
* Library jars, EJB jars or application client jars
* The WEB-INF/classes directory of a war
* Directories in the JVM classpath
{quote}
The *The WEB-INF/classes directory of a war* is important here. It defines what it means specifically for a web module to be a bean archive. It defines that the web1.war, as a bean archive, only contains classes located under the _WEB-INF/classes_ directory.
Therefore, in our application we have the following bean archives:
* web1.war (contains WEB-INF/classes only) and ejb1.jar which are modules
* weblib1.jar, weblib2.jar and earlib1.jar which are library jars
Therefore, there is no overlap as library jars are handled separately (by 5.1 and 12.1) and the bean archive for a web module is defined to contain classes from _WEB-INF/classes_ only.

[JBoss JIRA] (CDI-533) Bean Deployment archive conflicts between section 5 and section 12
by Mark Struberg (JIRA)

The correct implementation is section 12.
{quote}
No that is not correct. The _original_ (way back in early 2008) intention was EE module. Then there was some discussion about interceptor ordering ambiguity and it got narrowed to JARs. But this was only intended for interceptors, and only half done. So it is still ambiguous till today and many containers enable Alternatives for the whole EE module if they are enabled in one of the beans.xml in it. Even the EE6 RI behaved that way (and only got 'patched' by a Weld update and the RI implementers seems to not even have been aware of that functional change).
The important point is that the per-jar interceptor/alternatives/decorator interpretation is pure PITA for all users.

Fwd: bean archives
by Emily Jiang
I agree with Mark. I am confused about section 5 and section 12. Weld-2
leaves the work of specifying the bean archive to the integrator. I am
wondering how the new version of app server using Weld-2 can pass the CDI
1.1/1.2 CTS at all if the integrator creates its bean archives based on
section 12.
I am guessing CDI 1.1/1.2 cts, the updated version of CDI 1.0(?), is based
on section 5. Can someone confirm? The spec needs to be updated to remove
the conflict between section 5 and section 12.

[JBoss JIRA] (CDI-533) Bean Deployment archive conflicts between section 5 and section 12
by Emily Jiang (JIRA)
Emily Jiang created CDI-533:
-------------------------------
Summary: Bean Deployment archive conflicts between section 5 and section 12
Key: CDI-533
URL: https://issues.jboss.org/browse/CDI-533
Project: CDI Specification Issues
Issue Type: Clarification
Components: Packaging and Deployment
Affects Versions: 1.2.Final
Environment: n/a
Reporter: Emily Jiang
In CDI1.2 spec, the definition for bean archive are conflicting between section 5 and section 12;
In section 5,
Beans and their clients may be deployed in modules in a module architecture such as the Java EE environment. In a module architecture, certain modules are considered bean archives. In the Java EE module architecture, any Java EE module or library is a module. The Java EE module or library is a bean archive if it contains a beans.xml file.
This section talks about the bean deployment on the module or library level. It indicates one web module (may contain web-inf\lib etc) is a single bean archive. The smallest unit is a module or a lib.
While in section 12:
When determining which archives are bean archives, the container must consider:
• Library jars, EJB jars or application client jars
• The WEB-INF/classes directory of a war
• Directories in the JVM classpath
It indicates each jar should be a bean archive. The smallest unit is a jar.
I started this conversation with Mark, Jozef, Antoine, Romain. The correct implementation is section 12. So section 5 needs to be reworked.
All conversation is on the cdi-dev mailing list.

> h2. 4. Event Ordering
> Should we decide to add events ordering in CDI 2.0, the order will be keep in asynchronous observer notification. If there are a mix of synchronous and asynchronous observer, asynchronous will be called first in order, then synchronous in their order (async has priority on sync).
> h2. 5. Event state (payload mutability)
> We'll keep payload mutability with async events (but should explicitly specify it). That means that we should guarantee the event state consistency between observers and in case of ordered observers the fact that observer N+1 get the event state at the end of observer N.

Re: [cdi-dev] cdi-dev Digest, Vol 55, Issue 1

Hi,
I'm in a new project and country now.
Actually though earlier releases as of now CDI plays an important role
here, so unless IRC or the web-based variants are blocked for security
reasons I might be able to join the call.

Today's meeting
by Antoine Sabot-Durand
Hi all,
Today I’d like to discuss EDR1 release and its final content.
And then, discuss about the next step:
- finishing features started in EDR1
- prioritize our feature list for the coming months.
Meeting is still at 6:00pm CET on IRC (freenode #cdi-dev channel)
Regards,
Antoine

[JBoss JIRA] (CDI-280) clarify usage of 'bean' term usage in the spec
by Martin Andersson (JIRA)
[ https://issues.jboss.org/browse/CDI-280?page=com.atlassian.jira.plugin.sy... ]
Martin Andersson commented on CDI-280:
--------------------------------------
What is a "tenant proxy"? You mean a proxy written by the application developer himself? If so, then I'd not worry about it at all.
Half of the rest is related to EJB and JPA.
If CDI enforce different proxy types, then it should be clarified (but it doesn't right?). "CDI proxy" would be a valid term that encapsulate all types (but again, there are no different CDI proxy types?), or just "proxy" for short. The bottom line is that if we deal with a proxy, why not just call it that? Everything in the spec is "contextual" already. The word feels a bit bloated.
Actually, I think that the word "proxy" is one of those things that is quite clear without semantic noise. Now you want to replace all references made to a proxy with "contextual reference"? I just don't get it why.

[ https://issues.jboss.org/browse/CDI-280?page=com.atlassian.jira.plugin.sy... ]
Mark Struberg commented on CDI-280:
-----------------------------------
No, just calling it 'the proxy' would not be enough. Actually there are many different kind of proxies involved besides the 'Contextual Reference'. And depending on the implementation it could even be more.
1.) interceptor proxies
2.) decorator proxies
3.) subclassing proxies for abstract decorators
4.) EJB API proxies
5.) EJB NIV proxies
6.) JPA proxies
7.) customer specific proxies like custom InjectionTarget
8.) tenant proxies
etc
All those can be either used in parallel or some of them even stacked for the same bean!

--------------------------------------
bq. The proxy for a Contextual Instance should be referred to as 'Contextual Reference'
Or why not just call the proxy a proxy? If the origin of the proxy is not clear, call it a CDI proxy. In either way, I find that "contextual reference" is confusing.
