问题
I'm using jdk7, netbeans8, jasperreport5.6.0 and libraries :
jasperreport5.6.0.jar,
commons-logging-1.1.2.jar,
commons-beanutils-1.9.2.jar,
commons-digester3-3.2.jar,
commons-collections4-4.0.jar,
itext-2.1.0.jar.
But after running my application, i got the error, "java.lang.ClassNotFoundException:org.apache.commons.collections.map.ReferenceMap".
How can i resolve it?
