[JBoss JIRA] Created: (SOLDER-49) Unsatisfied dependencies for type-safe logger
by Dan Allen (JIRA)
Unsatisfied dependencies for type-safe logger
---------------------------------------------
Key: SOLDER-49
URL: https://jira.jboss.org/browse/SOLDER-49
Project: Seam Solder
Issue Type: Bug
Components: Core
Reporter: Dan Allen
JBoss Logging caches the value of the system property jboss.i18n.generate-proxies, which determines whether it will generate the proxies that the type-safe loggers in Solder rely on.
Although this property is set in a static block in the LoggerExtension, it may not be soon enough depending on the order that extension are loaded. In some cases, JBoss Logging caches a value of null, then all type-safe logging injection points break (and we get major complaints in the forums).
You can fix this temporarily by starting the application server with the following system property:
-Djboss.i18n.generate-proxies=true
The real issue is in JBoss Logging. It shouldn't be caching this system property so aggressively. But the use of a system property in general is way too fragile.

[JBoss JIRA] Created: (SEAMJMS-4) Event Mapping Observer Method Interfaces - Ingress
by Jordan Ganoff (JIRA)
Event Mapping Observer Method Interfaces - Ingress
--------------------------------------------------
Key: SEAMJMS-4
URL: https://jira.jboss.org/browse/SEAMJMS-4
Project: Seam JMS
Issue Type: Feature Request
Components: Event Bridging
Reporter: Jordan Ganoff
Priority: Blocker
Implement the ingress routing (receive JMS messages from a destination should produce CDI events) as per the spec.
>From JSR-299-20090521.pdf:
10.7. JMS event mappings
An event type may be mapped to JMS topic.
An event mapping is a special kind of observer method that is declared by an interface, for example:
interface EventMappings {
void mapLoggedInEvent(@Observes LoggedInEvent event, @Events Topic eventTopic);
}
Where the parameter of type Topic resolves to the following message destination:
@Resource(name="java:global/env/jms/Events")
@Produces @Events Topic eventTopic;
The event parameter specifies the mapped event type and bindings. Every message destination representing a topic that
any injected parameter resolves to is a mapped topic.
An event mapping may be specified as a member of any interface.
All observers of mapped event types must be asynchronous observer methods. If an observer for a mapped event type is
not an asynchronous observer method, the container automatically detects the problem and treats it as a deployment prob-
lem, as defined in Section 12.4, "Problems detected automatically by the container".
For every event mapping, the container must:
• send a message containing the serialized event and its event bindings to every mapped topic whenever an event with
the mapped event type and bindings is fired, and
• monitor every mapped topic for messages containing events of that mapped event type and bindings and notify all loc-
al observers whenever a message containing an event is received.
Thus, events with the mapped event type and bindings are distributed to other processes which have the same event map-
ping.

[JBoss JIRA] Created: (SEAMREMOTING-22) docs - compress enabled by default
by Jozef Hartinger (JIRA)
docs - compress enabled by default
----------------------------------
Key: SEAMREMOTING-22
URL: https://issues.jboss.org/browse/SEAMREMOTING-22
Project: Seam Remoting
Issue Type: Bug
Affects Versions: 3.0.0.Beta2
Reporter: Jozef Hartinger
Priority: Minor
Fix For: 3.0.0.CR1
The docs[1] say that one should use
<script type="text/javascript" src="seam/resource/remoting/resource/remote.js"></script>
for development and
<script type="text/javascript" src="seam/resource/remoting/resource/remote.js?compress=true"></script>
for production, however, the compress parameter seems to default to "true" as both URLs give me the same result.
Therefore, the docs should say:
<script type="text/javascript" src="seam/resource/remoting/resource/remote.js"></script> - production environment - compress enabled
<script type="text/javascript" src="seam/resource/remoting/resource/remote.js?compress=false"></script> - development mode - compress disabled
