NoSuchMethodError in main thread while reading xlsx using apache poi

Question

my code is

[...]
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.X         


        

Answer 1

I ran into exactly the same issue as you, and I found the following jar files have to be used to solve the program:

• poi-bin-3.8.zip
• opencsv-2.3.jar
• poi-ooxml-3.8.jar
• poi-ooxml-schemas-3.8.jar
• xmlbeans-2.3.0.jar
• dom4j-1.6.1.jar

Newer version will bring trouble.
