Re: [wildfly-dev] WildFly domain on OpenShift Origin
by Thomas Diesler
/reducing the cc noise
Yes, I was hoping to hear that this has already been thought about.
Is there a design document for this JMX aggregation?
What are the possible target environments and functional requirements?
Would this be reusable in a plain WildFly domain?
cheers

the WildFly 9 org.jboss.metadata.common module is missing javax.persistence...
by Scott Marlow
Some of the WildFly 9 TCK tests are failing because
javax.persistence.api is missing from the org.jboss.metadata.common
module. In WildFly 8.2, we had [1] org.jboss.metadata which had various
javax APIs. In WildFly 9, org.jboss.metadata.ejb has the different
javax APIs but org.jboss.metadata.common [2] does not.
How should this be fixed?

Change WebServices subsystem to use PersistentResourceXMLDescription
by Claudio Miranda
Hi, to better understand subsystem api, I am changing the WS subsystem
to use the PersistentResourceXMLDescription, more in line with the
other subsystem api.
There are some wsdl settings, they are xml elements.
<subsystem xmlns="urn:jboss:domain:webservices:2.0">
<modify-wsdl-address>${ws.modify-wsdl-address:true}</modify-wsdl-address>
<wsdl-host>${jboss.bind.address:localhost}</wsdl-host>
<wsdl-port>${ws.wsdl-port:9090}</wsdl-port>
<wsdl-secure-port>${ws.wsdl-secure-port:9443}</wsdl-secure-port>
<wsdl-uri-scheme>https</wsdl-uri-scheme>
<wsdl-path-rewrite-rule>s/jaxws-jbws2150-codefirst/xx\/jaxws-jbws2150-codefirst/g</wsdl-path-rewrite-rule>
What do you think of those settings as attributes ?
<subsystem xmlns="urn:jboss:domain:webservices:2.0">
<wsdl-settings modify-wsdl-address="${ws.modify-wsdl-address:true}"
wsdl-host="${jboss.bind.address:localhost}"
wsdl-port="${ws.wsdl-port:9090}"
wsdl-secure-port="${ws.wsdl-secure-port:9443}"
wsdl-uri-scheme="https"
wsdl-path-rewrite-rule="s/jaxws-jbws2150-codefirst/xx\/jaxws-jbws2150-codefirst/g"/>
Later I can submit it for review if is of interest.
Kind regards

JDK 9 images are now modular with JDK 9 Early Access build 41
by Rory O'Donnell
Hi Jason/Tomaz,
The initial changesets for JEP 220: Modular Run-Time Images [1] are
available
with JDK 9 early-access build 41 [2].
To summarize (please see the JEP for details):
- The "jre" subdirectory is no longer present in JDK images.
- The user-editable configuration files in the "lib" subdirectory
have been moved to the new "conf" directory.
- The endorsed-standards override mechanism has been removed.
- The extension mechanism has been removed.
- rt.jar, tools.jar, and dt.jar have been removed.
- A new URI scheme for naming stored modules, classes, and resources
has been defined.
- For tools that previously accessed rt.jar directly, a built-in NIO
file-system provider has been defined to provide access to the
class
and resource files within a run-time image.
More details are available at Mark Reinhold's latest blog entry [3]
