Wildfly Welcome-Content
Greeting forum people,
I am running Wildfly 8.2.0.Final in a Docker container. I have deployed a simple Java web application to the root context. Most of the time everything works as expected. There are times, however, when I go to localhost:8080/ rather than seeing my application I get the Wildfly welcome page. A little later, my application is back. I'm guessing that something is going on with my app that makes it temporarily unavailable so Wildfly displays it's welcome content.
So my questions...
- Under what conditions does Wildfly serve the welcome-content rather than an application deployed to the same context?
- If there is a problem with my application, as i suspect, why do I see the Wildfly welcome screen instead of an error, (like a 503 or something)?
- If I have an application deployed to /, should I remove the welcome-content? And if so, would I then get a error response instead of welcome page when my application is flaking out.
I am deploying my application via a Dockerfile, ADD myapp.war /opt/jboss/wildfly/standalone/deployments/
Here is my configuration,
<subsystem xmlns="urn:jboss:domain:undertow:1.2">
<buffer-cache name="default"/>
<server name="default-server">
<http-listener name="default" socket-binding="http"/>
<host name="default-host" alias="localhost" default-web-module="myapp.war">
<location name="/" handler="welcome-content"/>
<filter-ref name="server-header"/>
<filter-ref name="x-powered-by-header"/>
</host>
</server>
<servlet-container name="default">
<jsp-config/>
<websockets/>
</servlet-container>
<handlers>
<file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>
</handlers>
<filters>
<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"/>
</filters>
</subsystem>
Thanks for helping to increase my understanding...
