Question

I would like to remove all HTML comments from my facelets before delivering to end users. Does any standard approach exist?

Answer 1

There are actually two ways:

1. To remove all comments, add this to web.xml:

    <context-param>
        <param-name>jakarta.faces.FACELETS_SKIP_COMMENTS</param-name>
        <param-value>true</param-value>
    </context-param>
   

   or when you’re still on JSF 3.x/2.x:

    <context-param>
        <param-name>javax.faces.FACELETS_SKIP_COMMENTS</param-name>
        <param-value>true</param-value>
    </context-param>
   

   or when you’re still on JSF 1.x which doesn’t use Facelets as default view technology yet:

    <context-param>
        <param-name>facelets.SKIP_COMMENTS</param-name>
        <param-value>true</param-value>
    </context-param>
   

2. To remove specific comments only, use <ui:remove>.

    <ui:remove><!-- This is a HTML comment. --></ui:remove>
