do you have your classes located at
%CATALINA_HOME%\webapps\WebAppName\WEB-INF\classes ?
or perhaps the jar which contains the taglib is located at
%CATALINA_HOME%\webapps\WebAppName\WEB-INF\lib ?
You may want to break out the build.xml and execute the target which
contains jasper compile as a separate task
http://ant.apache.org/manual/OptionalTasks/jspc.html
in order to isolate this error..
Anyone else?
