Apache POI Workbook class not found
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
First, I want let you know what I'm using:
- Eclipse IDE 2018-09 (4.9.0) Java-SE 10
- Apache POI 4.0.0-20180907
I don't mixing any JARs files with other version and I add to my project all the JARs in the folder except "poi-examples-4.0.0".
Let take a look of this code:
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Workbook;
public class Program
{
public static void main(String args)
{
Workbook workbook = new HSSFWorkbook();
}
}
I getting this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook
at Program.main(Program.java:8)
Caused by: java.lang.ClassNotFoundException: org.apache.poi.hssf.usermodel.HSSFWorkbook

at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)
... 1 more
And if I'm trying this code:
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class Program
{
public static void main(String args)
{
Workbook workbook = new XSSFWorkbook();
}
}
I getting this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/xssf/usermodel/XSSFWorkbook
at Program.main(Program.java:8)
Caused by: java.lang.ClassNotFoundException: org.apache.poi.xssf.usermodel.XSSFWorkbook

Can someone can explain me what I'm doing wrong?

NoClassDefFoundErroris a run time error. So while compile time the classHSSFWorkbookwas found. But on run time the same class was not found. So there must be a discrepancy between class path settings compile time vs. run time. Check your IDE settings for that. But for usingXSSFWorkbookplease read: Can Apache POI be compiled/used with Java 10 or newer?.

Apache POI does support Java 10, just not with modules, see the FAQ which Axel linked to!
