Answer 1

It means that you have several jar files in your JasperReports Library classpath... just use:

• commons-beanutils-1.8.0
• commons-collections-2.1.1
• commons-digester-1.7
• commons-javaflow-20060411
• commons-logging-1.0.4
• groovy-all-1.7.5
• iText-2.1.7
• jasperreports-4.5.0 (any version)
• png-encoder-1.5
• poi-3.7-20101029 (Or poi-3.6)

and problem solved...
