I am getting the following runtime exception:
[java] Exception in thread "AWT-EventQueue-0"
java.lang.ClassCastException: org.apache.poi.hssf.usermodel.HSSFWorkbook
cannot be cast to org.apache.poi.ss.usermodel.Workbook
[java] at
....ExportToExcelAction.getXLSWorkBook(ExportToExcelAction.java:153)
The code is this:
private Workbook getXLSWorkBook() { Workbook genericWorkbook =
null; HSSFWorkbook wb = new HSSFWorkbook();
genericWorkbook = (Workbook)wb; return genericWorkbook; }
If I do this same thing for an XSSFWorkbook, it works fine. I have tried any
number of different ways to do this cast for HSSFWorkbook. Either the
compiler flags it or I get a runtime exception no matter what, I haven¹t
figured out how to do this. This should work like XSSFWorkbook since they
both implement the Workbook interface.
I am using 3.5 Beta 5.
Any thoughts? Is this a bug?
