      import java.io.Serializable;

      import javax.webbeans.Named;
      import javax.webbeans.RequestScoped;

      @Named
      @RequestScoped
      public class Foo implements Serializable {
      public String getMsg()

      { return "Hi"; }

      }

      foo.xhtml:

      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml">

      {foo.msg}

      </html>

      It will fail with the following exception:

      Note that it will NOT fail if Foo implements another interface such as a user-defined interface. That is, it seems to occur only
      with java.io.Serializable.
