I suspect that you have a file which includes header.jspf - and that parent
file is not including the fn tag lib. (The (potentially) bad error message is
another issue)

What tomcat version and commands are you using? IIRC - jspf files by

I started with Tomcat 5.0.30, but have switched to 5.5.12. The ant
targets that I am using is similar to the ones in the Tomcat docs:
<target name="init-jsp" depends="build">
<mkdir dir="build-jsp"/>
<mkdir dir="src-jsp"/>
</target>
<target name="build-jsp" depends="init-jsp">
<taskdef classname="org.apache.jasper.JspC" name="jsp2">
<classpath>
<fileset dir="${env.CATALINA_HOME}/common/lib">
<include name="*.jar"/>
</fileset>
<fileset dir="lib">
<include name="*.jar"/>
</fileset>
<path location="classes"/>
</classpath>
</taskdef>
<jsp2 uriroot="../../myapp" outputDir="src-jsp"/>
<javac srcdir="src-jsp" destdir="build-jsp" deprecation="true">
<classpath>
<classpath>
<fileset dir="${env.CATALINA_HOME}/common/lib">
<include name="*.jar"/>
</fileset>
<fileset dir="lib">
<include name="*.jar"/>
</fileset>
<path location="classes"/>
</classpath>
</javac>
</target>
<target name="clean-jsp">
<delete dir="src-jsp"/>
<delete dir="build-jsp"/>
</target>
The "build" target that "init-jsp" depends on builds my Java code and
places it into myapp/WEB-INF/classes.
When I run "ant build-jsp" it fails on the <jsp2> line with the
following:
BUILD FAILED
/home/chris/myapp/WEB-INF/build.xml:470:
org.apache.jasper.JasperException:
file:/home/chris/myapp/header.jspf(49,74) The attribute prefix fn does
not correspond to any imported tag library
However, in taglibs.jspf, the functions JSTL is included and the jar
file is in myapp/WEB-INF/lib. This is why I suspect that JspC is
trying to compile header.jspf.
