Jasper Compilation with Ant including custom taglibs

[jo...@fwd.at]

hi there,

I've used a taglib from the jstl/core-package and would like to compile 
it.
If I try so using ant and a jspc-task, I get the following error:

2003-03-23 05:54:11 - ERROR-the file '\nodigsig.jsp' generated the 
following gen
eral exception: org.apache.jasper.JasperException: This absolute uri 
(http://jav
a.sun.com/jstl/core) cannot be resolved in either web.xml or the jar files 
deployed with this application
  [jasper2] Error in class org.apache.jasper.JspC
BUILD FAILED

==> I already tried to include the libraries as properties (external 
dependencies), but no success.

Has anybody else tried to compile JSPs using custom taglibs?

             outputDir="${basedir}/src" />

  </target>
