Description mirumpf 2009-02-26 21:14:53 UTC 
When copying and pasting the following code from the current DevGuide into my
project I got a ClassCastException:


public com.sun.star.sheet.XSpreadsheet getSpreadsheet( 
        com.sun.star.sheet.XSpreadsheetDocument xDocument, int nIndex) {  
    // Collection of sheets
    com.sun.star.sheet.XSpreadsheets xSheets = xDocument.getSheets();
    com.sun.star.sheet.XSpreadsheet xSheet = null;
    try {
        com.sun.star.container.XIndexAccess xSheetsIA =
(com.sun.star.container.XIndexAccess)
UnoRuntime.queryInterface(com.sun.star.container.XIndexAccess.class, xSheets);
226:        xSheet = (com.sun.star.sheet.XSpreadsheet) xSheetsIA.getByIndex(nIndex);
    } catch (Exception ex) {
    }
    return xSheet;
} 

The exception being thrown is:

java.lang.ClassCastException: com.sun.star.uno.Any
	at getSpreadsheet(MyClass.java:226)

Instead of 


  xSheet = (com.sun.star.sheet.XSpreadsheet) xSheetsIA.getByIndex(nIndex);
  xSheet = (com.sun.star.sheet.XSpreadsheet) xSheetsNA.getByName(aName);

the correct code must be:

  xSheet = (XSpreadsheet) UnoRuntime.queryInterface(XSpreadsheet.class,
      xSheetsNA.getByName(aName));
  xSheet = (XSpreadsheet) UnoRuntime.queryInterface(XSpreadsheet.class,
      xSheetsIA.getByIndex(nIndex));
