Te code which calls this class is:

{code}
public static void main(String[] args) {

SheetManager manager=new SheetManager("Minor.xls");
{code}

My compiler is JVM 1.5
Excel version 2003.

Thanks in advance.

Hello again,I noticed that this Exception is thrown just when i try to get a specific sheet(workbook.getSheet(0)),so I suppose that JExcel has some trouble opening some specific sheets with defined names,list,macros.... I don´t know.

If somebody knows about problems opening sheets I thank his/her opinion.....
