Reading XLSX file and converting it to XML using java maping.

[Former Member]

Hello Experts, ( I should say saviors 🙂 )

I am trying to read an XLSX file and convert it to XML using java mapping.I have addded following Apache POI files in classpath:

poi-ooxml-3.9.jar

poi-ooxml-3.10-FINAL-20140208.jar

poi-ooxml-schemas-3.10-FINAL-20140208.jar

stax-api-1.0.1.jar

xmlbeans-2.3.0.jar

poi-3.15-beta2.jar

dom4j-1.6.1-sources.jar

.The code complies but it throws below exception while execution:

Exception in thread "main" java.lang.IllegalAccessError: org/apache/poi/util/POILogger.log(ILjava/lang/Object;)V

at com.reader.XlsxReader.main(XlsxReader.java:36).

The below code is currently reading the XLSX:

package com.reader;

import java.io.FileInputStream;
import java.io.IOException;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet; //New imports to read XLSX format
import org.apache.poi.xssf.usermodel.XSSFWorkbook; //New imports to read XLSX format

public class XlsxReader {

public static void main(String[] args) throws IOException {

FileInputStream fin = new FileInputStream("D:\\Test\\Empl.xlsx");
XSSFWorkbook wb = new XSSFWorkbook(fin);
XSSFSheet sheetIn = wb.getSheetAt(0);

int rows = sheetIn.getLastRowNum();
for (int row = 0; row <= rows; row++) {
XSSFRow xcelRow = sheetIn.getRow(row);
int columns = xcelRow.getLastCellNum();

for (int col = 0; col <= columns; col++) {
Cell cell = xcelRow.getCell(col);
String cellVal = null;
System.out.print("ROW[" + row + "] Col[" + col + "]");
if (cell != null) {
if (0 == cell.getCellType()) {
Double dVal = cell.getNumericCellValue();
cellVal = dVal.toString();
} else
cellVal = cell.getStringCellValue();
System.out.println(cellVal);
}
}
}
wb.close();
fin.close();
}

}

Please excuse me for such a long message but I could not find any attachment options Could you please guide me where I am wrong?

Thanks,
