Is there an OJB taglib
Hello,
I am looking for an OJ taglib for using OJB within JSP pages. Please can
anyone tell me if such a lib is available.
The searches I have done only seem to return Jelly taglibs.
Thanks
Neil

Re: Is there an OJB taglib
Posted by Thomas Mahler <th...@web.de>.
In April Jacob Hookom (hookomjj@uwec.edu) contacted us and announced the
completion of an OJB taglib (see his mail below). I did not hear any
updates on this topic so far.
