title: How to remove Sheets form Excel sheet using JExcel
body: <p>I am trying to remove sheets from an existing excel file  using jxl api.</p>
  
  <p>I cannot use</p>
  
  <pre><code>WritableWorkbook wwb = new Workbook.createWorkbook("abc.xls");
  </code></pre>
  
  <p>as I do not want to create a new workbook, rather I want to use an existing one. </p>
  
  <p>I cannot use </p>
  
  <pre><code>Workbook wb = new Workbook.getWorkbook("abc.xls");
  </code></pre>
  
  <p>as this would get the file in <strong>read only</strong> mode. There is no "<strong>getWorkbook</strong>" method for the class <strong>WritableWorkbook</strong>. Please tell me how to go about it.</p>
  
  <p>I searched through examples online but in each case a new workbook is being created rather than using an existing one.</p>
