Hi everybody, I hope anybody can help me.
I have a problem with running the embedding example "FopServlet" which comes with the latest FOP Distribution 0.20.4.. Compiling and installation under Tomcat 4.0.1 was successful, but if i call the servlet in my browser --with xml-path and xsl-path as parameters-- I always get the error message "javax.servlet.ServletException: org.apache.fop.svg.SVGElementMapping is not an ElementMapping". The error occurs in line "Driver driver = new Driver();" in the method renderXML. Thank you very much for helping Martin Here is the servlet code: /* * $Id: FopServlet.java,v 1.4.2.2 2002/03/21 17:18:05 chrisg Exp $ * Copyright (C) 2001 The Apache Software Foundation.
