Re: [seam-dev] Seam Startup Performance
by Mark Struberg
Folks, what if we step back and fix the CORE of this disaster?
Lets not pickup non CDI scope annotated beans as @Dependent automatically anymore!
We could automatically enable this feature if we detect a version="1.1" in beans.xml. This way we can keep backward compatibility

Hi Guys,
I was just looking at the startup performance of the Seam 3 booking example on AS7, and I noticed that because the Seam 2 archives that it deploys are bean archives, it actually wastes quite a lot of time on startup registering Seam 3 classes as CDI beans that are never used.
It occurred to me that we can get around this by using a beans.xml that includes welds <scan> extension in beans.xml to prevent uneeded beans being registered we could significantly improve the performance and memory usage of Seam 3 apps.
Now that the ridiculous visibility and extensions in non-bean archive problems are resolved, I'm in favor of switching back to registering beans manually rather than using beans.xml. That seems like a performance enhancement that's portable, so that we don't suck if Weld isn't the provider.
But I agree we should do one of the two options. We'll be moving tests around in Seam to align the setup, so it seems like a good time to run tests with the updated bean registration strategy.

Re: [seam-dev] Seam Startup Performance
by Mark Struberg
Of course, we'd first need to do a performance evaluation to see if it would help a lot.
In OpenWebBeans we did it 'half way' now. Whenever we detect that a class doesn't have any Scope annotation (directly or indirectly via an @Stereotype), nor any @Inject or @Produces inside, we only initialize the bean meta info as an empty shale. And if it gets injected into another bean later, we just initialize this bean lazily.
Of course, this trick didn't help that much with scanning performance (maybe ~15%), but it greatly reduced the memory footprint.
Btw, we really should spec the exclude paths in beans.xml. I now found the regarding issue already filed in
https://issues.jboss.org/browse/CDI-87
I added a proper description, but Pete, could you please edit the title and give it a more meaningful text? :)

At this point, I think that may actually be a good option. I can't get forge to start up in under 8 seconds anymore. I'm all for doing this I suppose, though it will be a bit of a departure from the current functionality. I like the auto-pickup, but this performance is pretty attrocious :(

Issue resolved with JBoss AS 7 CR1 and Seam Social
by Antoine Sabot-Durand
Hi all,
Just to let you know I managed to run social Web App example with Jboss 7-CR1. The trick was to have 2 beans.xml file. One in META-INF for Seam-Config to read beans configuration and one in WEB-INF in order to having the server exposing CDI bean for JSF view. I drop the Seam-Faces and its dependency Seam-International since I don't need them and they cashed the deployment.
If I put config info in WEB-INF/beans.xml, Seam-Config doesn't read them and if I don't put beans.xml in WEB-INF my JSF views don't access CDI bean (LE doesn't trigger any code). I don't know if it's the expected behavior for Seam-Config to read beans.xml only in META-INF....

Deployment issues with JBoss 7 CR1
by Ove Ranheim
Hi,
The speed improvement of JBoss 7 is just beyond awesome and no words could cover my excitement to this fantastic piece of engineering work.
During this weekend I tried to get my project deployed in JBoss 7 and it looks like I'm close to a success. I'd like to share my experience and point out where it fails for me.
Deployment assembly looks like:
* 16 project extensions related to my project (my project is named parts)
* Uses Weld 1.1.1, Seam Solder, Faces, International, Servlet, Persistence, Mail, Catch, Config, JMS, Remoting and Security.
* Depends on Hibernate Core 3.6.0 (because of Seam Persistence), Hibernate Search 3.3.0 because of Hibernate Core, HornetQ and JAXB.
* Includes all non-jboss-6 included jars (mvel, ora, joda-time, httpclient, etc.)
What makes it hard to figure out is what dependencies should be opted in or out. The jboss-as-parent-7.0.0.CR1 gives idea to figure out dependency versions, but it's still hard to tell what's available in the deployment classpath for my WAR in JBoss 7 (standalone-preview).
I added an extra profile to my pom to opt in jars that needs to be included in the J7 deployment:
<profile>
<id>j7</id>
<dependencies>
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.5.10</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.10</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-search</artifactId>
<!-- version>3.4.0.Final</version -->
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.6.0.Final</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
</dependencies>
</profile>
The good thing is that I see a long list of registered EJB 3.x and 3.0 beans being successfully deployed. But, it fails with a CNF exception for log4j and slf4j loggers. I'm clueless to how to solve logger dependencies.
I posted this issue on AS7 User forum (see bottom): http://community.jboss.org/thread/168853
According to the migration guide: https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application...
we need to include "legacy" Hibernate EntityManager, Validator and Annotations to get Seam to work. But, it does not tell whether this relates to Seam 2 or 3. Besides, wouldn't it make sense to opt out those and use the already available Hibernate 4-Beta2 and exclude "legacy" Hibernate dependencies. The footprint of the deployment would be smaller. And how does this affect the JPA in J7 when I include "legacy" hibernate?
The logger is my current showstopper and I don't know what error will be next. Has anyone deployed the Seam Booking example successfully to J7? I would like to see the migration guide clearer to the above and certainly would like to help out on the documentation side and do testing. Or in any other way be of help.
What we need is a JBoss7 deployment matrix profile to act as a reference to everybody using Seam 3 and JBoss 7 project.
Cheers,
Ove

Proposed features for Seam JCR Hackfest
by John D. Ament
Hello,
We are having a Seam Hackfest night on July 14, I think starting around 6pm
eastern. The target module for this hackfest is Seam JCR. We've identified
a few pieces of functionality that we want to cover:
1. OCM support (binding POJO's to JCR Nodes, ala hibernate)
2. Security integration for managing credentials used within JCR
implementations.
3. Seam Catch integration for handling exceptions.
There's one I'm skipping for now, which requires us to have a CDI managed
entity listener. This is a proposed JPA 2.1 feature, but not available in
the persistence module.
If anyone's interested, we would love the support.

Stuck with bug in Weld + Jdk6_u26
by Antoine Sabot-Durand
Hi Team,
The last apple java update bring jdk to 1.6.0_26 version and triggers this bug in my webapp (JBoss 6) : https://issues.jboss.org/browse/WELD-897
I tried to switch to JBoss 7 CR1 but got some exception with seam international and joda time missing. Removing Seam-Faces which pull Seam-International let the app deploy without exception, but all the backing beans calls seem to be dead (the page displays but all EL is ignored).
So is there were a way to update weld in JBoss 6 or something I'm missing with JBoss 7 ?
Thks,
Antoine

[John Ament] SEAMJMS-34 Added a few more tests. SEAMJMS-45 Added an event
payload type that encapsulated all of the configuration options for JMS
events.
[John Ament] SEAMJMS-45 Looks like I missed a class or two.
[John Ament] SEAMJMS-46 Added support for configurable session, connection
factory, moved all in to API.
[John Ament] SEAMJMS-36 Fixed the status watcher example. MIssed a few
serializable APIs and cleaned up a bunch of design issues in the
application.
