How to let Arquillian know that JBoss is running on localhost

Just add the following to the configuration section:


My complete file was:

   <container qualifier="jboss" default="true">
        <!-- By default, Arquillian will use the JBOSS_HOME environment variable to find the JBoss EAP installation.
             If you prefer not to define the JBOSS_HOME environment variable, alternatively you can uncomment the
             following `jbossHome` property and replace EAP_HOME with the path to your JBoss EAP installation. -->
            <property name="managementAddress">${arquillian.wildfly.host:localhost}</property>
            <property name="jbossHome">/Users/jeremydavis/Workspace/summit/jboss-eap-7.1</property>

Failed to link org/wildfly/swarm/container/runtime/RuntimeServer

I got the following error running the WildFly Swarm jaxrs-cdi example:

The fix was pretty simple: rebuild WildFly Swarm itself.  After a quick mvn clean install everything was up and running.

Apache on OSX Yosemite

I was recently doing some web stuff on my laptop for the first time in a while. I could pull up the "It Works!" page, but nothing else.
This Apple forum post solved it.
Blogged here to help search results :)

My fifth JavaOne started today.  I attended a Java University class.  It was interesting to be on the other side of that sort of presentation.

Red Hat is well represented this year.  There is a microsite on Red Hat Developer.

Stop by the Red Hat booth in the vendor hall if you are attending.  We have presentations all day long, and there is a rumor about trucker hats...

Rails 4 MiniTest error

I got the following cryptic error on a new project:

~/…/unit.rb:1037:in `block in process_args’: invalid option: —use-color (OptionParser::InvalidOption)

Thanks to this blog for pointing the way.

I did not copy/paste the suggested code though.  I just ran :

guard init minitest
