read excel file with aspose version 2.5
<p>I want to read excel file with aspose version 2.5, I know that in the latest version we can do this like : 
<code>
Workbook w = new Workbook(fileStream);
Cells cells = w.getWorksheets().get(0).getCells();
</code></p>

<p>I didn't found any documentation on aspose 2.5.</p>
