I've been an HSSF user for a little while.
I have this problem, perhaps a stupid beginning problem.
I have unloaded the "jakarta-poi-1.4583-dev-bin.zip" file from 
http://jakarta.apache.org site
Unzipping this file I have used the file jakarta-poi-1.1-dev.jar in the classpath of 
my development tool (ORACLEJDev9i) relating to a new project.
The used application is that shown in the examples directory of 
HSSF/jakarta.apache.org site and is repoted below:

//**********************************************************
package org.apache.poi.hssf.usermodel.examples;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import java.io.FileOutputStream;
import java.io.IOException;

/**
 * This example creates a new blank workbook.  This workbook will contain a single 
blank sheet.
 *
 * @author Glen Stampoultzis (glens at apache.org)
 */
public class NewWorkbook
{
    public static void main(String[] args)
        throws IOException
    {
        HSSFWorkbook wb = new HSSFWorkbook();
        String path="C:/JavaAppl/KmsWorkspace/ProjectWorkBook/classes/workbook.xls";
        FileOutputStream fileOut = new FileOutputStream("workbook.xls");
        wb.write(fileOut);
        fileOut.close();
    }
}
//**********************************************************
During the compilation I have no problems, but when I execute I receive this problem:

Exception in thread main
java.lang.NoClassDefFoundError: org.apache.poi.hssf.HSSFLog     void 
org.apache.poi.hssf.usermodel.HSSFWorkbook.<clinit>()      void 
org.apache.poi.hssf.usermodel.examples.NewWorkbook.main(java.lang.String[]) Process 
exited with exit code 1.

What could be the problem?

Thanks to all
