That�s the answer, you need to specify org.apache as your JSP
package. Here�s a example from my build.xml how to use <jspc>
<jspc srcdir ="${webapp}/jsp" //Place where JSPC can find
web.xml
destdir ="${webapp}" //place where jsp files will
be created
verbose ="9"
package="org.apache" //root package
uriroot ="jsp" // alias that you would use
for JSP pages
webxml ="${webapp}/WEB-INF/jsp.xml" // file to manage
JSP files
classpathref="base-path">
<webapp basedir="${webapp}"/>
</jspc>
