我試圖導出數據庫中的用戶列表爲pdf。當我點擊我的「打印表」按鈕時，這個異常返回。按鈕正在執行generateReport（）方法。net.sf.jasperreports.engine.util.JRResourcesUtil.findClassLoaderResource（Ljava/lang/String; Ljava/lang/ClassLoader;）
一些細節：
- 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的日誌文件是在這裏：在Web瀏覽器中

我搜查，但我無法找到任何解決方案。
我關閉輸出和輸入流。它沒有影響。我運行了「mvn dependency：analyze」命令，並且發現了一些警告。我運行了另一個命令「mvn dependency：tree -Dverbose」，它省去了重複的工作，並省略了衝突信息。我應該刪除所有這些嗎？我是maven的新手。 – suspicioususer
該命令只顯示重複的庫，用於刪除一個動脈，請參閱解釋http://stackoverflow.com/questions/547805/exclude-all-transitive-dependencies-of-a-single-dependency或類似的主題 –
