Exception while using Apache POI on a JSP

I'm trying to implement Apache POI to display the data on an Excel file into some inputs on my web page. I'm getting this exception:

exception 
org.apache.jasper.JasperException: Unable to compile class for JSP
org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:677)

root cause

And this the code I have on my .jsp file:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>

<%@ page import="java.io.FileInputStream, 
java.io.FileNotFoundException, 
java.io.IOException, 
org.apache.poi.hssf.usermodel.HSSFCell, 
org.apache.poi.hssf.usermodel.HSSFRow,
org.apache.poi.hssf.usermodel.HSSFSheet,
org.apache.poi.hssf.usermodel.HSSFWorkbook;"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head></head>
<body>

<% 
     HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream("excel.xls"));
     HSSFSheet sheet = workbook.getSheetAt(0);
     HSSFRow row = sheet.getRow(1);
     double Something,Something1,Something2,Something3,Something4;

        Something= row.getCell(0).getNumericCellValue();
        Something1= row.getCell(1).getNumericCellValue();
        Something2= row.getCell(2).getNumericCellValue();
        Something3= row.getCell(3).getNumericCellValue();
        Something4= row.getCell(4).getNumericCellValue(); 

 %>

<div>
    <table>
        <tr>
            <td>Something: </td>
            <td><input type="text" value="<% Something %>"></td>
        </tr>
        <tr>
            <td>Something1: </td>
            <td><input type="text" value="<% Something1 %>"></td>
        </tr>
        <tr>
            <td>Something2: </td>
            <td><input type="text" value="<% Something2 %>"></td>
        </tr>
        <tr>
            <td>Something3: </td>
            <td>    <input type="text" value="<% Something3 %>"></td>
        </tr>
        <tr>
            <td>Something4: </td>
            <td><input type="text" value="<% Something4 %>"></td>
        </tr>
    </table>
</div>
</body>
</html>

Does someone knows where's the problem?

Not sure which server you are using. But if it is Tomcat 7.0.57 or later(Have a look at this link too), then you need to remove the semicolon (;) at the end of import directives. Try removing that and it should work.
