从所需的 .class 文件间接引用，甚至构建路径设置正确 apache POI..？

   }

我在这两个包中遇到错误

导入 org.apache.poi.poifs.filesystem.*;

导入 org.apache.poi.hpsf.DocumentSummaryInformation;

无法解析 org.apache.poi.poifs.filesystem.POIFSFileSystem 类型。它是从所需的 .class 文件间接引用的

我附上了我的 java 构建路径的快照...因为程序需要

poi-scratchpad-3.2-FINAL-20081019.jar

它在java构建路径中正确设置..那么为什么我收到这样的错误..帮助..!!

找到了它需要 poi-3.7.jar 的解决方案
