[JBoss JIRA] (WFLY-3149) Windows service on 64 bit systems cannot be stopped
by Michael Amthor (JIRA)
[ https://issues.jboss.org/browse/WFLY-3149?page=com.atlassian.jira.plugin.... ]
Michael Amthor commented on WFLY-3149:
--------------------------------------
Two of the possible solutions here worked for me:
Removing %CREDENTIALS% from service.bat and adding /controller 127.0.0.1:[current http mangement port] for my install script did the job for me.
Adding a user and password for the service.bat call did not change anything idependent of %CREDENTIALS%. Not for an admin user and not for a batch user. I can't understand why the %CREDENTIALS% have any influence since they are not set?!?

> Occurence details:
> 1. The issue occured following a restart of the application server
> Analysis details:
> 1. From the perspective of the JBOSS 7 admin console ... the admin console shows that the "apex.war" application is deployed and "enabled". I believe it should not display "enabled" as the context has failed to start and it is NOT capable of servicing requests.
> Details to reproduce:
> 1. Download Oracle Apex Listener 1.1.4 from:
> http://www.oracle.com/technetwork/developer-tools/apex-listener/downloads...
> 2. Unzip the war file e.g jar xvf apex.war
> 3. Modify the web.xml by adding:
> <context-param>
> <param-name>config.dir</param-name>
> <param-value>/opt/jboss/apex_config_dir</param-value>
> </context-param>
> 4. Create the path "/opt/jboss/apex_config_dir".
> 5. Zip the war file.
> cd locationContaining the Web-INF directory
> jar cvf apex.war *
> 6. Deploy war file and enable via admin console. Stop Server. Start server.
> 7. Exception occurs.
> NOTE: there could be an additional step to reproduce. Will detail if above does not work.
> NOTE2: I can redeploy the above application and get it working again by removing some files that are auto generated by apex.war (so a partial bit of this issue is probably application related).

[JBoss JIRA] (WFLY-4127) @TransactionAttribute ignored on SFSB PostConstruct lifecycle callback
by Martin Kouba (JIRA)
[ https://issues.jboss.org/browse/WFLY-4127?page=com.atlassian.jira.plugin.... ]
Martin Kouba commented on WFLY-4127:
------------------------------------
[~swd847] Well, I see no active transaction. But it seems that it's not a regression - changing the default value from REQUIRED to NOT_SUPPORTED just revealed that {{org.jboss.as.ejb3.component.EJBComponentCreateService}} does not consider non-public lifecycle callback methods when building transaction attributes map and so the default value is applied (it was originally REQUIRED and that's the reason why the TCK test passed before).
See alse EJB 3.2 spec, section 8.3.7 "Specification of the Transaction Attributes for a Bean’s Methods":
{quote}
For a stateful session bean, the transaction attributes are specified for the PostConstruct, PreDestroy, PrePassivate or PostActivate lifecycle callback interceptor methods, if any.
{quote}
And Interceptors 1.2 spec, section 2.6 "Interceptors for Lifecycle Event Callbacks":
{quote}
Lifecycle callback interceptor methods can have public, private, protected, or package level access.
{quote}
Anyway, I'm not also sure whether NOT_SUPPORTED should be the default value for SFSB (see my comment about {{StatefulComponentDescription}} in the description).

> Management clients need a mechanism to disambiguate between cases where a management resource registration exists for a a wildcard PathElement (e.g. PathElement.pathElement("service"), represented in CLI syntax as service=*) versus for a fully specified PathElement (e.g. PathElement.pathElement("service", "remote"), represented as service=remote). In the fully specified case they need to be able to see the full path element when querying for types using the read-children-types operation.
> The term we have reached consensus on for describing registrations against a non-wildcard PathElement is a 'singleton'. The registration represents a type, and since within the context of its parent only one address will be valid for that type, that type has a singleton nature.
> The task here is to add a new boolean parameter to the read-children-types operation, "include-singletons". The parameter will be optional, default value of 'false', which will result in unchanged default behavior from what exists in WF 8.x and earlier.

[JBoss JIRA] (WFCORE-208) Expose 'singleton' type information in read-children-types
by Heiko Braun (JIRA)
[ https://issues.jboss.org/browse/WFCORE-208?page=com.atlassian.jira.plugin... ]
Heiko Braun commented on WFCORE-208:
------------------------------------
the whole point of this exercise is to be able to derive resource-descriptions for singleton resources
which may, or may not exist (have been added yet). as such the respoonse needs to include the child information regardless if the singleton resource is given (has been added yet) or not

> Management clients need a mechanism to disambiguate between cases where a management resource registration exists for a a wildcard PathElement (e.g. PathElement.pathElement("service"), represented in CLI syntax as service=*) versus for a fully specified PathElement (e.g. PathElement.pathElement("service", "remote"), represented as service=remote). In the fully specified case they need to be able to see the full path element when querying for types using the read-children-types operation.
