Adding Classes at Run-time
by Jason Lee
I have an odd question. I have a situation where I'm manually opening a
JAR and adding its classes to the ClassLoader. What I'd like to be able
to do is have Weld scan these classes for any relevant annotations and
take the proper actions, just as if the JARs were in the classpath when
the application started. I've been staring at the JavaDocs (build
locally, btw, as I can't find them on the web :| ) but I don't see any
way to request that Weld inspect a given class. Is it there and I'm
missing it? Am I going to have cobble together that functionality? Am
I asking for something that can't be done (right now)? Any nudges in
the right direction would be much appreciated. :)

Re: [weld-dev] Pom's in maven central referring to jboss org nexus :(
by Paul Gier
Maven doesn't have a good solution for this. The choice is either change the poms in our repository or tell people not to put repos in the poms, but Nexus doesn't have a way to enforce this.

WELD-001408 Injection point has unsatisfied dependencies
by Sebastian E. Ovide
Hi All,
on Glassfish 3.0.1 I'm getting this error which doesn't make sense to me...
org.glassfish.deployment.common.DeploymentException: WELD-001408 Injection
point has unsatisfied dependencies. Injection point: field
com.sebas.SecurityEAO.saltGenerator; Qualifiers:
[@javax.enterprise.inject.Default()]
here the code:
@Stateless
public class SecurityEAO implements Serializable {
@Inject
SaltGenerator saltGenerator;
...
}
public interface SaltGenerator {
...
}
public class SaltGeneratorSecure implements SaltGenerator {
...
}
any ideas ?

memory leak in guava <r09
by Sebastian Otaegui
Hello guys,
I was reading the jenkins mailing list and someone mentioned a memory leak
in guava.
I saw that weld uses guava so I am sending you this to make you aware in
case you are not.
I haven't looked at the weld-core code, so you may not be affected.
here is the bug and it was fixed in r09
http://code.google.com/p/guava-libraries/issues/detail?id=573&can=1&q=mil...
Best regards

Those who do not understand Unix are condemned to reinvent it, poorly.
Any sufficiently recent Microsoft OS contains an ad hoc,
informally-specified, bug-ridden, slow implementation of half of Unix.
