我试图导出数据库中的用户列表为pdf。当我点击我的“打印表”按钮时，这个异常返回。按钮正在执行generateReport（）方法。net.sf.jasperreports.engine.util.JRResourcesUtil.findClassLoaderResource（Ljava/lang/String; Ljava/lang/ClassLoader;）
一些细节：
- 的iReport 5.5.0
- net.sf.jasperreports 5.5.0（pom.xml中）
- JasperReports的3.5.3（pom.xml中）
- Glassfish的4.0
- JDK 1.8
- 的Netbeans 8.1
Glassfish的日志文件是在这里：在Web浏览器中

我的.jrxml删除UUID部分。 uuid属性导致另一个例外。
users_sex字段类型是smallint mysql。 iReport自动创建类型为java.lang.Integer的.jrxml文件。
JRUser1.jrxml预览：
我搜查，但我无法找到任何解决方案。
我关闭输出和输入流。它没有影响。我运行了“mvn dependency：analyze”命令，并且发现了一些警告。我运行了另一个命令“mvn dependency：tree -Dverbose”，它省去了重复的工作，并省略了冲突信息。我应该删除所有这些吗？我是maven的新手。 – suspicioususer
该命令只显示重复的库，用于删除一个动脉，请参阅解释http://stackoverflow.com/questions/547805/exclude-all-transitive-dependencies-of-a-single-dependency或类似的主题 –
