Help

i´m trying the JasperReports for Java Developers Book source code it has a MapCollectionDSReportServlet example but it says that you had to use version 1.0.1 of jasperreports, I try to update the example for using jasperreports-1.2.5 jar and an error comes out. I also try putting commons-javaflow-20060411 jar in the classpath but the error remains.

 

GRAVE: Servlet.service() para servlet MapCollectionDSReportServlet lanzó excepción
