title: Unable to open excel using ApachePOI - Getting Exception
body: <p>While trying to open an excel using ApachePOI I get</p>
  
  <p><code>org.apache.poi.openxml4j.exceptions.InvalidOperationException: Can't open the specified file: 'C:\Users\mdwaipay\AppData\Local\Temp\poifiles\poi-ooxml-1570030023.tmp'</code></p>
  
  <p>I checked. No such folder is being created. I am using Apache POI version 3.6.</p>
  
  <p>Any help? A similar code was running fine in a different workspace. At loss of thoughts here.</p>
  
  <p>Code:</p>
  
  <pre><code>public Xls_Reader(String path) {
    this.path=path; 
    try { 
        fis = new FileInputStream(path); 
        workbook = new XSSFWorkbook(fis); 
        sheet = workbook.getSheetAt(0); 
        fis.close(); 
    }
    catch (Exception e) 
    { e.printStackTrace(); 
    } 
  }
  </code></pre>
