Description Patrick Goovaerts 2002-09-04 12:41:20 UTC
We are unable to instantiate the HSSFWorkbook-object.
HelloExcel class is executed with all poi-jars in our classpath as wel as the 
log4j.jar

statement in error:

    HSSFWorkbook werkboek = new HSSFWorkbook();

This is the error:
Message ID: RNQ0301
Message: Java exception received when calling Java method (C G D F).
cause: RPG procedure TRQTSRC in program TRQTSRC/LXCONT received Java 
exception "java.lang.NoSuchMethodError:" when calling method "<init>" with 
signature "()V" in class "net.sourceforge.poi.hssf.usermodel.HSSFWorkbook".
...

this is the code of HelloExcel:

import java.io.*;
import net.sourceforge.poi.hssf.usermodel.*;

public class HelloExcel {
  public static void main(String[] args)
    throws IOException {
    FileOutputStream bestand =
      new FileOutputStream(args[0]);
    HSSFWorkbook werkboek = new HSSFWorkbook();
    HSSFSheet werkblad = werkboek.createSheet();
    werkboek.setSheetName(0, "eerste werkblad");
    for (short rownum = (short) 0; rownum < 10; rownum++) {
      HSSFRow rij = werkblad.createRow(rownum);
      HSSFCell cel = rij.createCell(
        (short) 0, HSSFCell.CELL_TYPE_NUMERIC);
      cel.setCellValue(rownum + 1);
      cel = rij.createCell(
        (short) 1, HSSFCell.CELL_TYPE_NUMERIC);
      cel.setCellValue((rownum + 1) * (rownum + 1));
    }
    werkboek.write(bestand);
    bestand.close();
  }
}

Please don't take this harshly but...

You really need to upgrade.  That version is what... nearly a year old?  It may
be a bug (I think this is actually something wrong with your environment and
most likely a mismatch in the version of log4j), but if so then it must have
been fixed in one of the last two production releases as lots of people are
using it and successfully instantiating HSSFWorkbook :-).  Secondly, this type
of question really belongs on the poi-user list
http://jakarta.apache.org/poi/getinvolved/index.html.  One can suspect strongly
that not being able to run elementary code like this would be a usage issue
rather than a bug. 

I'm marking this as INVALID and suggesting strongly that:
1. You upgrade to 1.5.1
2. Ask your question on the list

at least two good reasons for this:
1. There is no way in heck I'm ever going to fix a bug in a production release
that has been superceded by a later version (because even if I did it would go
into the next version)
2. Not all of the user community reads the bug reports, and I'm like 99% sure
you're running this on a machine I know nothing about, but I'll bet some of the
other POI users do, and they could help you way better than the developers who
are mostly on Window/Unix.
