After upgrading regexp and ORO, this error message appeared

2008-12-22 14:35:00 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: This absolute uri (http://jakarta.apache.org/taglibs/regexp-1.0) cannot be resolved in either web.xml or the jar files deployed with this application

The hack was to edit /home/www/java/trust/WEB-INF/regexp.tld and change

<tlibversion>1.0.1</tlibversion>
to
<tlibversion>1.0</tlibversion>
A different hack is to edit /usr/local/lib/jakarta-taglibs/jakarta-taglibs-regexp-1.0.1/regexp.tld and make the same change and then rebuild the javapages release
