I am trying to start with JSF installation.

In JSF file, I just added h tag and f tag.
Once I do <f:view> it gives below error.

I can’t understand what is missing. I added two Jars…

  1. javax.faces-2.1.8.jar
  2. javax.servlet.jsp.jstl-api-1.2.1.jar
  3. primefaces-3.2.jar

    The stacktrace indicates that you’re using the old and deprecated JSP for some reason. JSP has been succeeded by Facelets since JSF 2.0 end of 2009.

    Rename ClinicInformation.jsp to ClinicInformation.xhtml and read the Facelets tutorial. For some kickoff examples how such a Facelets file should look like, check the following answers:

    Note that you can configure JSF 2.0 to use JSP instead by some web.xml params, but this is absolutely not recommended as it’s an inferior view technology. Even more, PrimeFaces doesn’t support JSP at all.
