[seam-dev] Excel implementation

[Nicklas Karlsson]

The implementation of the the top level tag could then be something like

		CellFormat[] cellformats = ; //parse tags for cell definitions etc
		ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
		WritableWorkbook workbook = Workbook.createWorkbook(bytestream);
		WritableSheet worksheet = workbook.createSheet("data", 0);
		bytestream.toByteArray()
		// pseudo code section
		loop data rows i
		  loop data columns j
		     worksheet.addCell(ExcelFactory.getCell(i, j, celldata, cellformats[i]))
		  end loop
		end loop
		pretty much the same with bytestream.toByteArray() as is done in the
pdf UIDocument.encodeEnd

Could/should there be a src/xls/org/jboss/seam/xls/ui structure and if
so, what parts should be extraced to some common package?
The DocumentStore concept itself?
