I have setup Openfire 4.0.2 on CentOS6 using the RPMs from the website. Nothing else is on the system.
When I install the websockets plugin and visit https://full.working.hostname:7443/ws/ I get a 404 error. The certificate is valid. Openfire is the latest. It was installed from the available plugins page.
The Java version installed by Openfire with the RPM package is:
1.8.0_74 Oracle Corporation – Java HotSpot™ Server VM
Where specifically should I look for additional information? What specifically should I do to continue debugging? Please be very specific.
