Read an excel file using JSP in MII 12.1

Hi,
I want to read an excel file using jsp page. I dont want to use the UDS or ODBC for connecting to excel.
I am trying to use org.apache.poi to read the excel file in jsp page.
While running, its showing a compilation error "package org.apache.poi.hssf.usermodel does not exist"
I have the jar files for it, where do we need to upload it so that jsp page works.
Thanks a lot
Regards,
Neha Maheshwari

The user doesn't want to save the excel file in server.
I want to upload file and save its contents in database.
I have the code to read and save excel data in database but not able to get the location to deploy the jar file.
In general, if we are creating a jsp page in MII workbench which is using some jar file.
Whats the location to upload this jar file so that the jsp page works correctly?

How to read the excel file using webdynpro abap?

Hi,
how to read and modify excel file using webdynpro abap?
Regards,
Pavani

For reading excel file follow the steps :
1. Use a File upload UI element and bind it with xstring.
2. Now your excel will be uploaded and stored in Xstring.
3. Convert Xstring to String data using FM 'HR_KR_XSTRING_TO_STRING'.
4. Now split the string at new line so as to make an internal table .
Ex . SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE it_table.
here it_table is type table of string.
5.now loop at the internal table and separate the content of this table separated by tab.
Ex. SPLIT wa_table AT cl_abap_char_utilities=>horizontal_tab INTO TABLE it_new.
it_new type string_table.
6. For more info , refer this thread :

Download Excel file using JSP

Hi All,
I am working on a JAVA/JSP application. JSP page passes the user inputs to JAVA page (using POST method) which queries to the database and generate an Excel file and returns the link for that file. I am displaying that link in JSP page ("Your file is successfully saved. Click here to download or view your file).
Now what I want is when the user clicks on the link, open/save dialog will appear which give flexibility to the user to download or view the file in same JSP page. The problem is I don�t want to post again the data or dont want to open a child window. How to set the content type without posting it (I don�t know much about this). Is there any way to do this?
Any help is highly appreciated. Thanx in advance
Cheers

Hi! I 've a code to read an excel file using JDBC-ODBC bridge. I can read the values, but any special characters is readed wrong, just symbols. The special characters are of spanish language. This is my code:

          Locale.setDefault(currentLocale);

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
     * @param args [0] = source filename

    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println ("Syntax: java -cp . Kopy source destination");
            System.exit(1);
        File in = new File(args[0]);
        long fileLength = in.length();
        long t = System.currentTimeMillis();
        FileInputStream fis = new FileInputStream (in);
        FileOutputStream fos = new FileOutputStream (args[1]);
        FileChannel fci = fis.getChannel();
        FileChannel fco = fos.getChannel();
        fco.transferFrom(fci, 0, fileLength);
        fis.close();
        fos.close();
        t = System.currentTimeMillis() - t;
        NumberFormat nf = new DecimalFormat("#,##0.00");
        System.out.print (nf.format(fileLength/1024.0) + "kB copied");
        if (t > 0) {

Opening an Excel File using Excel 97 from a JSP populated page(Urgent)

Hello,
I am using a JSP Page to populate data from the DB.
When I am opening the same as an Excel File the JSP code is coming as the Excel page whenever Excel 97 is being used,but when Excel2000 or 2003 is being used then the data are coming as Excel formatted.I used the following code(JSP) :
<head>
<%
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","inline; filename=ExtractData.xls");
%>
</head>

I can't even tell what the difference is between "coming as the Excel page" and "coming as Excel formatted". But then when people make urgent posts they very rarely spend the time to describe the problem accurately. Why bother when it's so damn urgent?

Error reading excel file using POI.

Hi ,
I am having some problem when reading the excel file.
While reading excel file I am getting error-java.io.IOException: Unable to read entire block; 4 bytes read; expected 512 bytes.
part of my code:-
InputStream stream = objFormFile.getInputStream();
POIFSFileSystem fs = new POIFSFileSystem(stream);//getting above error here.
HSSFWorkbook wb = new HSSFWorkbook(fs);
Case 1:
I download the file on the system ,save it ,and then directly upload it to the system ,I get the above error .
Case 2:
It works fine if I download the excel and manually open and save it and then upload it .
I am using JDK1.4.1 and poi-2.5.1-final-20040804.jar.
Can any one please help me out for the above problem?
Edited by: hruday on Jul 31, 2008 3:20 AM

Instead of using POIFSFileSystem, try to directly create the HSSFWorkbook
InputStream stream = objFormFile.getInputStream();
//POIFSFileSystem fs = new POIFSFileSystem( stream );//getting above error here.
HSSFWorkbook wb = new HSSFWorkbook( stream );

If the "it" refers to a compressed (zipped) spreadsheet that you downloaded, the ".ods" extension is used by LibreOffice and probably OpenOffice (which are free versions of MS Office) for spreadsheets, which would suggest that wherever you're getting that "Excel" file from has switched to one of those programs. I've tried opening an .ods file from LibreOffice using MS Office 2013 for Windows and it does open though with a warning that some things have been changed. I don't know if Office for Mac can normally open .ods files. But if your need is to just open .ods files, take a look at LibreOffice.
