--- Comment #7 from Mark B <[email protected]> --- Not so sure that this is an error but it certainly could be a problem with the javadoc for the XSSFWorkbook/OPCPackage classes. Had a quick play with the code this morning and read the full stacktrace produced when the exception is thrown. The source of the exception is the write method of the workbook - or one of the methods it calls - and it appears to be caused by the fact that the OPCPackage is no longer available when the workbook is being written out. If the call to the close() method of the OPCPackage instance if moved to follow the write() method of the workbook, then the exception is not thrown. So, it seems that if a workbook is cretade from an instance of the OPCPackage class, the OPCPacakge instance must not be disposed of until after the workbook has been written. This change the the code, removed the problem completely; org.apache.poi.openxml4j.opc.OPCPackage opc = org.apache.poi.openxml4j.opc.OPCPackage.open(filename); org.apache.poi.xssf.usermodel.XSSFWorkbook wb = new org.apache.poi.xssf.usermodel.XSSFWorkbook(opc); java.io.FileOutputStream fileOut = new java.io.FileOutputStream(filename); wb.write(fileOut); opc.close(); fileOut.close(); Perhaps documenting this in the javadoc for the workbook and OPCPackage classes would be sufficient.
