Gathering diagnostic data
by James Livingston
Hi,
I do support for JBoss at RH, especially lower level components like the
JVM and core server, and I've come to realise that we don't have
particularly good mechanisms for gathering diagnostic data. Obviously
there is logging, but for a number of problems it isn't enough. There is
also the JDR subsystem, but that has the serious limitation that the
server instance(s) have to be working correctly to use it.
One piece of data that I think can be useful for a common set of
problems are thread dumps. For standalone instances Oracle/OpenJDK's
'jstack' tool is useful, but for domain mode you need to manually go to
each machine and find the correct process ID to use it. Something that
could potentially be useful is to be able to tell Host Controllers to
take a thread dump from the servers it manages (or all of them), using
the same Attach/SA APIs as jstack.
A feature to allow HC-based extensions as mentioned in the thread about
the RHQ agent could be useful for implementing this too. Right now, I
believe it would need to be added to the HC code directly.
Is this something that might be possible or a good idea to do? I have
some ideas about other things that may be useful, like per-thread CPU
usage which RH support currently uses a pile of shell scripts for, but
starting with one thing may be simpler.

Issue with HTTP upgrade for remote naming on OpenShit?
by Jeff Mesnil
Hi,
Now we have an OpenShift cartridge for WildFly 8.0.0.Final (hanks Farah!), I’m adding instructions to the JMS quickstarts to deploy them on OpenShift.
The helloworld-mdb is working fine but I have an issue with the helloworld-jms one[1].
In this quick start, the Java client makes a lookup to JNDI to retrieve the JMS resources.
The quickstart uses the “http-remoting://localhost:8080” as the JNDI provider URL for a local WildFly server.
When I host WildFly on OpenShift, that URL should translate to http-remoting://<app>-<namespace>.rhcloud.com:80 (in my case http-remoting://helloworldjms-jmesnil.rhcloud.com:80)
However this does not work:
$ mvn clean compile exec:java -Djava.naming.provider.url=http-remoting://helloworldjms-jmesnil.rhcloud.com:80
…

SEVERE: Failed to connect to any server. Servers tried: [http-remoting://helloworldjms-jmesnil.rhcloud.com:80 (java.io.IOException: Invalid response code 200)]
Remote naming is correctly complaining that the HTTP Upgrade handshake responded with a 200 OK instead of a 100 Continue.
Indeed, the deployed WildFly server does not upgrade my connection. You can check by hand using curl:
$ curl -v http://helloworldjms-jmesnil.rhcloud.com -H 'Connection:upgrade' -H 'Upgrade:jboss-remoting' -H 'Sec-JbossRemoting-Key: Xj8ZjttC3aixB1bAZ9w39A=='

I tried removing the proxy-address-forwarding attribute but that did not change anything.
Has someone managed to use remote naming with WildFly on OpenShift?
Am I missing something obvious to make it run?

GSoc aspirant wishing to seek valuable guide regarding JBoss AS 7(wildfly) quickstarts project.
by Giriraj Sharma
Hii,I am Giriraj Sharma, a dedicated GSoc'14 aspirant(3 years' experience
in JavaSE+1.5 year's experience in JavaEE) from Dept. of Computer Science,
National Institute of Technology, HP, India, interested in making valuable
contribution to the project* JBoss AS Quickstarts : JBoss AS
management,services and modules*(
https://community.jboss.org/wiki/GSOC14Ideas?_sscc=t<https://community.jboss.org/docs/DOC-52233?_sscc=t>)
listed in JBoss GSoc 2014 ideas Page.
I was initially interested in contributing quickstarts for hibernate ORM
with JBoss AS. It was mentioned as a proposed project on the ideas page. I
forked *jboss-developer/jboss-eap-quickstarts* repository from github a few
weeks back and I read the guide to contributing to a quickstart (
http://www.jboss.org/jdf/quickstarts/get-involved/).* I have been actively
committing on git repository
(https://github.com/jboss-developer/jboss-eap-quickstarts
<https://github.com/jboss-developer/jboss-eap-quickstarts>) since past
15-20 days. One of my commit has been merged and my several other(11)
commits are under code review.* But,I recently came to know that hibernate
quickstarts have been removed form GSoc 2014 JBoss project ideas page.The
mentors told me that it was listed in GSoc 2014 ideas page because it was
copy-pasted from GSoc 2013 ideas page but is not a part of GSoc 2014
ideas.This project is removed in the new modified list of GSoc 2014 ideas.
The project proposal *JBoss AS Quickstarts : JBoss AS management,services
and modules *is still a part of *GSoc 2014 JBoss ideas* Page.I am really
enthusiastic about contributing quickstarts for JBoss AS as it will let me
help in understanding the architecture and scripting down the server. I am
currently reading through the documentation of JBoss AS *Admin Guide*
*https://docs.jboss.org/author/display/AS7/Documentation
<https://docs.jboss.org/author/display/AS7/Documentation>. *I have also
forked up the wildfly/wildfly repository (wildfly/wildfly ·
GitHub<https://github.com/wildfly/wildfly>)
and read contribution guide (Hacking on
AS7<https://community.jboss.org/docs/DOC-15596>
).
Basically, I am a newbie but, an application developer for J2EE
technologies. I have used JBoss AS 7 for my past projects but here I shall
be dealing with JBoss AS itself.* I wish to have a bit of your guidance so
as how to start up working upon JBoss AS quickstarts and is the project
proposal about working on quickstarts(demo applications) or is it about
actually writing code/patches for JBoss AS. Please give me brief details
about how I may start up contributing for this project proposal.*
