尝试创建小型 jasper 报告时出错

Question

我已将 Jasperstudio 6.1.1 插件添加到我的 eclipse 中。我已将以下 jars 添加到我的库中。

jasperreports-6.1.1
commons-beanutils-1.8.0
commons-collections-2.1
commons-digester-1.7
commons-loggin-api-1.0.2
groovy-all-1.7.5
iText-4.2.0
ojdbc6

当我尝试执行独立 java class 时出现以下错误。我认为错误是因为我的公共版本但不确定如何找到确切的版本。

我刚刚发现 solution.The 问题出在 commons-collect 版本上。我将它升级到 commons-collection-3.2.1.jar 并且它有效。谢谢
