Just an initial step to run websocket application on IBM Liberty Profile 8.5.5.5. After did lots of research I found I needed to add a feature on the Liberty server.xml file. 

<featureManager>
    <feature>websocket-1.0</feature>
     ....... 
</featureManager>

But as soon as I added that line on the configuration I'm getting a warning that

The feature 'websocket-1.0' is not recognized
server.xml /WebSphere Application Server V8.5 Liberty Profile/servers/defaultServer
line 5 Liberty Profile Configuration Problem

Any thought? Do I needed to add any Jar file for that?

In the 8.5.5.5 or earlier websocket feature is not contained in the downloaded jar. You have to install it from the repository using the following command:

featureManager install websocket-1.0 --when-file-exists=ignore

see the following page - Java WebSocket 1.0.

The 8.5.5.6 version is Java EE 7 compatible and contains webSocket-1.1 feature already built in, so you may download that one.

The feature files are in [Liberty Install]/lib/features folder.

However, I don't see websocket-1.0 or websocket-1.1 in Liberty 8.5.5.5

Try to use 8.5.5.6, you should see websocket-1.1.mf

For OpenLiberty navigate to [OpenLiberty Install]/bin via shell and execute:

featureUtility installFeature websocket-1.0 --acceptLicense

This will install the missing feature to the folder [OpenLiberty Install]/lib/features.
