I am getting error in these two packages
我在这两个包中遇到错误

导入 org.apache.poi.hpsf.DocumentSummaryInformation;
The type org.apache.poi.poifs.filesystem.POIFSFileSystem cannot be resolved. It is indirectly referenced from required .class files
类型 org.apache.poi.poifs.filesystem.POIFSFileSystem 无法解析。它是从所需的 .class 文件间接引用的
I have attached a snapshot my java build path...since the program require
我附上了我的 java 构建路径的快照...因为程序需要

回答by Gagravarr
You have two problems. One is that you're using Apache POI 3.2, which dates from 6 years agoand there have been a huge number of bug fixes since then
你有两个问题。一个是您使用的是6 年前的Apache POI 3.2，从那时起已经修复了大量错误
Second problem, you've missed some of the POI jars and their dependencies. See the components page for details. Basically though, to use HWPF, you need boththe poiandpoi-scratchpadjars on your classpath
第二个问题，您错过了一些 POI jar 及其依赖项。有关详细信息，请参阅组件页面。基本上，要使用 HWPF，您需要在类路径上同时使用poi和poi-scratchpadjar
