How can I remove HTML comments in my Facelets?

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

Solution

  • 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>
