title: Apache POI 3.9 : WorkbookFactory method not found
body: <p>In my app I have used Apache POI 3.8 for XLS file processing.</p>
  
  <p>Now I want to migrate to Apache POI 3.9 latest and stable version. I have added the JAR file poi-3.9-20121203.jar in my application and removed JARs related to POI 3.8.</p>
  
  <p>But it seems that, in 3.9 version, the WorkbookFactory class has been removed. </p>
  
  <p>So how can I create a <code>Workbook</code> with <code>WorkbookFactory</code> in Apache POI 3.9 ?</p>
  
  <p>I extracted the JAR and checked, there is no class like <code>WorkbookFactory</code>. </p>
  
  <p>Can anyone tell me how to create a new workbook with POI 3.9?</p>
