Configur Eclipse to use WildFly 8

In order to configure Wildfly/JBoss from Eclipse, start by installing the plugin "JBoss Tools" from Eclipse Marketplace. You only need to install JBossAS Tools, but you may install everything if you like:

After installing and restarting eclipse, go to File | New | Server and expand the JBoss Community option. Choose "WildFly 8 (Experimental)" and click Next: 

Now choose the location for the WildFly 8 installation and a JRE.

Remember that WildFly requires a JDK 1.7, therefore you will not be able to start it with an older JDK version.

The wizard will now ask if you wish to deploy a project. Choose the project you wish to deploy and click Add >.

Click Finish. WildFly 8 is now configured on your Eclipse environment! 
To enable automatic publishing of code changes, double click the server in the server tab:

This will open a server configuration window. In the "Publishing" section, set to check "Automatically publish after a build event" and set the interval to whatever fits you. In my experiences, 5 seconds works best. 
Finally change the value in the "Application Reload Behavior" section to: "\.jar$|\.class$"

Happy developing!
