If you drop this into TC's $CATALINA_HOME/webapps/ROOT and add the JSTL libs to $CATALINA_HOME/webapps/ROOT/WEB-INF/lib, it should do what you want. I tested this with TC 4.1.31 and Standard 1.0.6, but didn't do any sort of profiling. If you don't see the output from generated.jsp change for each request, try increasing the refresh interval. -- Kris Schneider D.O.Tech --------------------------------------------------------------------- To unsubscribe, e-mail: taglibs-dev-unsubscribe@jakarta.apache.org For additional commands, e-mail: taglibs-dev-help@jakarta.apache.org
