i have written a java servlet program, which has a html form to be filled. after filling the form the servlet generates a receipt and the values should be loaded into an excel table automatically. i have created a dsn for excel table ,but my program is working till generation of receipt and the values are not loading into excel table. would you help me in solving this problem?
1)Create form.html
<html> <body> <form name="userform" method="post" action="http://localhost:8080/examples/excelFile.jsp"> <table> <tr><td>Enter First Name:</td><td><input type="text" name="firstName"></td></tr> <tr><td>Enter Last Name:</td><td><input type="text" name="lastName"></td></tr> <tr><td>Enter User Name:</td><td><input type="text" name="userName"></td></tr> <tr><td>Enter Address:</td><td><input type="text" name="address"></td></tr> <tr><td>Enter Email ID:</td><td><input type="text" name="email"></td></tr> <tr><td>Enter DOB:</td><td><input type="text" name="dob"></td></tr> <tr><td><input type="submit" value="Export to excel"></td></tr> </table> </form> </body> </html>
2)Create excelFile.jsp
<%@page import="java.io.*"%> <%@page import="org.apache.poi.hssf.usermodel.HSSFSheet"%> <%@page import="org.apache.poi.hssf.usermodel.HSSFWorkbook"%> <%@page import="org.apache.poi.hssf.usermodel.HSSFRow"%> <%@page import="org.apache.poi.hssf.usermodel.HSSFCell"%> <% String value1=request.getParameter("firstName"); String value2=request.getParameter("lastName"); String value3=request.getParameter("userName"); String value4=request.getParameter("address"); String value5=request.getParameter("email"); String value6=request.getParameter("dob"); try{ HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet("Excel Sheet"); HSSFRow rowhead = sheet.createRow((short)0); rowhead.createCell((short) 0).setCellValue("First Name"); rowhead.createCell((short) 1).setCellValue("Last Name"); rowhead.createCell((short) 2).setCellValue("User Name"); rowhead.createCell((short) 3).setCellValue("Address"); rowhead.createCell((short) 4).setCellValue("E-mail Id"); rowhead.createCell((short) 5).setCellValue("Date Of Birth"); HSSFRow row = sheet.createRow((short)1); row.createCell((short)0).setCellValue(value1); row.createCell((short)1).setCellValue(value2); row.createCell((short)2).setCellValue(value3); row.createCell((short)3).setCellValue(value4); row.createCell((short)4).setCellValue(value5); row.createCell((short)5).setCellValue(value6); FileOutputStream fileOut = new FileOutputStream("c:\\File.xls"); wb.write(fileOut); fileOut.close(); out.println("Data is saved in excel file."); }catch ( Exception ex ){ } %>
