賈斯珀報告：未找到資源

Question

我正在使用Netbeans 7.1進行開發。

在我的碧玉報告中，我有子報告。 它完美地在一個地方工作。 我復制並粘貼到另一個地方，現在顯示此錯誤：

Answer 1

路徑D:\\ShareMarket\\build\\web\\WEB-INF\\classes\\custom\\kksharemarket是可疑的。 它應該是/custom/kksharemarket因為它位於應用程序的類路徑中。 應用程序可能打包在jar / war中，文件路徑不會。 可能資源不是通過文件系統獲取，而是在類路徑上獲取。 這通常是“資源”在java術語中的含義。

它適用於第一次開發，因為目錄結構存在。

Answer 2

D:\ShareMarket\build\web\WEB-INF\classes\custom\kksharemarket/contractDetail.jasper

                                                            ^^^

我猜你在編寫jasper文件路徑時硬編碼了文件分隔符。
