Question

I try to make word document using Apache POI 4.0.0, but i get error

Exception in thread \"AWT-EventQueue-0\" java.lang.NoClassDefFou

Answer 1

For poi-4.1.0 I had to add these to the classpath: dom4j-1.6.jar xmlbeans-3.1.0.jar commons-collections4-4.3.jar commons-compress-1.18.jar Only then did this work for Excel.xlsx File:

ExcelWBook = new XSSFWorkbook(ExcelFile);

Answer 2

Try searching for the class name then jar download you might find the specified jar files. "ex: XWPF jar files download." and download the classes of XWPF as jar files i got this problem before and I solved it like this but for me it was pdfBox. PS: Try searching for jar files for "org.apache.poi.xwpf" you will get more results.
