Tag Extra Info Classes not recongnized on 8.1

Question

          I am trying to migrate a web application from 6.1 to 8.1 and am running into an
          issue
          with custom tag libraries. These tags have TEI classes associated with them that
          are
          used to define fields in the JSP page where the tags are used. These fields are
          then
          referenced in the JSP. The JSP compiles fine in 6.1 but in 8.1 the compiler
          reports that
          it is unable to recognize the symbol for the various fields defined in the TEI
          and the
          JSP therefore fails to compile.
          Has anyone else run into this problem? Any workarounds or ideas about what needs
          to be
          done to make it work?
          Thanks in advance for your help.
          Regards,
          David Roytenberg
