I found no way to remove the Server header in EAP6. But there is a way to change its content. Just add the folling config to your standalone.xml: <system-properties> <property name=”org.apache.coyote.http11.Http11Protocol.SERVER” value=”foo”/> </system-properties> Or with cli: /system-property=org.apache.coyote.http11.Http11Protocol.SERVER:add(value=foo) Then your header just is Server: foo instead.

I often catch myself writing info-messages because jboss is configured to info-mode by default.

When you write a producer for FacesContext like this @Produces public FacesContext produce() { return FacesContext.getCurrentInstance(); } do not forget to specify a scope! Otherwise you will get an Exception when accessing the object when it is injected in a session scoped bean. So the correct version looks like this: @Produces @RequestScoped public FacesContext produce()

If you don’t want to send these headers with every response you have to disable them in your configuration file (standalone.xml). I just removed the following lines from my undertow subsystem (urn:jboss:domain:undertow:1.1): <filter-ref name=”server-header”/> <filter-ref name=”x-powered-by-header”/> … <response-header name=”server-header” header-name=”Server” header-value=”WildFly/8″/> <response-header name=”x-powered-by-header” header-name=”X-Powered-By” header-value=”Undertow/1″/> After a server restart the headers were gone.
