[n.manivel1911]

Hi Guys,

am using poi-3.2-FINAL-20081019.jar currently in my project. Recently facing the below issue when trying to build an excel CSV format report in my project

java.lang.NoSuchMethodError: org.apache.poi.hssf.usermodel.HSSFSheet.addMergedRegion(Lorg/apache/poi/hssf/util/Region;)

Can anyone help?

Below is the code snippet

import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.hssf.util.*;
String reportId = "BLRFORD";
HSSFWorkbook workbook = new HSSFWorkbook();
            HSSFSheet sheet = workbook.createSheet(reportId);
Region cellRegion1 = new Region(1, (short)3, 1, (short)4); 
            Region cellRegion2 = new Region(2, (short)3, 2, (short)4); 
            Region cellRegion3 = new Region(3, (short)3, 3, (short)4); 
            sheet.addMergedRegion(cellRegion1);

Hello,

 

The java.lang.NoSuchMethodError error means that the studio is not able to find the jar in the classpath of the project. The error has two possibilities - 

1. Either method definition doesn't exist
2. If method definitions exist, then they might have incompatible changes i.e. you might be using a different version of jar/class during runtime.

Hence, please check if the jar exists in the classpath of the project or if there is any compatibility change.
