Problem displaying an Excel File: Please Help

Hello,
I spent 3 hours this morning reading the forum on how to display an Excel file in the browser using JSP and I apologize in advance if the answer is in the forum.
I cut and paste many examples: My goal is to display an excel file on the browser.
Below is the code but the result is a disaster (please se after the code the result).
My question is how can I display an excel file using the browser. What's wrong with my code. Apparently it worked for many people on the forum.
Please help. I must do that by tomorrow and I had spent already so many hours.
THANK YOU SO MUCH IN ADVANCE.
So far the forum had helped me a lot.

Dear All,
There are three ways for achiving excel operations using java including excel to xml etc.
1. There is a very effective tool available for this operation is "jexcel". You can find it at http://www.andykhan.com/jexcelapi/index.html
2. Jakarta site has provided a very good tool by name jakarta poifs. one can find at jakarta site.
3. One can develop a very effective tool by combining these above tools togather.
The operations that can be performed are read, write, convert etc for excel. The major attraction of Jexcel is excel to xml conversion.

How to read Excel file in java

Respected sir/madam
I want to read the values from Excel file in Java program. How can I do that. When I searched over the net I came to know that you can treat Excel file as a Database and write the code as u write for making DB connections .
I did that but i am getting the following error ..can anybody please help..
This is the code what i have written
import java.io.*;
import java.sql.*;
public class ReadExcelFile {
Connection c;
Statement stmnt;
public void checkABA_Number()
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
c = DriverManager.getConnection("jdbc:odbc:ExcelTest","",""); // ExcelTest is the DSN name
stmnt = c.createStatement();
ResultSet rs = stmnt.executeQuery("select * from abadata"); // abadata is my Excel file name
while(rs.next())
System.out.println(rs.getString(1)+" "+rs.getString(2));
}catch(Exception e)
System.out.println(""+e.toString());
finally
try
stmnt.close();
c.close();
catch( Exception e )
System.err.println( e );
public static void main(String[] args)
new ReadExcelFile().checkABA_Number();
My Excel file starts from the first row and first column and also the first row contains the names of the column.
It give me the following error..
java.sql.SQLException: [Microsoft][ODBC Excel Driver] The Microsoft Jet database engine could not find the object 'abadata'. Make sure the object exists and that you spell its name and the path name correctly.
How can I deal with this.?I have properly selected the worksheet while giving the DSN . Is there any versionig problem with Excel or some drivers are in appropriate..and yes i chose Microsoft Excel Driver (.xsl) from ODBC .
I created System DSN.
Can anybody please help me with this ? I will be very gratefull for replies
Thanks in advance

here is the code to read excel file
public void readexel(String filename)
Connection c = null;
Statement stmnt = null;
try
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );

How to edit a spreadsheet (excel file) in the portal?

Hello experts,
at the moment i am working on the requirement to edit a spreadsheet in the portal.
Until now i was able to display an excel file with the help of the 'KM Document iView (without content filter)'.
Everything is displayed alright and i can perform changes in the spreadsheet.
BUT: There is no such thing like a Save-Button or something like that. Does the SAP NW Portal already provide a solution for this requirement? Or will i have to develop an own application?
I have already searched the forums and sap help, but i haven't found any solution. I can't imagine that such an easy requirement would need coding.
Best Regards
Marcus
(Po*nts will be rewarded for good answers)

Hi Marcus,
I do not think you can do the task the way you want. You will have to look for some workaround that may be download the file, edit it and then upload it back. You will have to code in your application for that. If you want to do this way I can help you further to edit and save the excel.

How can I create an Excel file?

I need to create an excel file as it was made from within Excel.
Thank in advance,

When you are talking about subfiles, are you talking like Package contents of an application?
Terminal application in Applications -> Utilities can give a command line grasp of all your files using the du command.
Type
man du
when entering the terminal, followed by the enter key.
Note, by default the terminal opens at the Home folder. To navigate outside the Home folder enter "/Volumes/name of mounted drive/folder/subfolder" as your path. If there are spaces in the name, putting quotes around the whole path can help. If you end your du command with a > name.txt a text file with the name name.txt will be plugged into your Home directory. That you can open with Excel and parse by /es thus giving you everything in Excel.

How do I save a excel file to be compatible...

How do I save a excel file from a pc to be compatible with my Mac?

Hi juicebars,
iWork is a productivity suite for Macs running OS or iThings running iOS. With a MacBook Pro you will need the OS version.
iWork consists of:
Pages, a word processor and page layout app (page layout mimics a drawing app). Pages can import Microsoft Word documents and you can edit and save them. Also Export as MS Word, PDF, plain text, RTF or ePub.
Numbers, a spreadsheet app that mimics a database. Numbers can import Microsoft Excel or CSV documents and you can edit and save them. Also Export as MS Excel, CSV or PDF.
Keynote, a presentation app. Keynote can open Microsoft Powerpoint. I don't use Keynote, so I can say no more.
You can buy the iWork suite from the App Store, or buy Pages, Numbers and Keynote separately.
There are some minor conversion glitches when converting between MS Office and iWork. If you are continually converting, it is best to buy Office or LibreOffice for Mac.
iWork does not take kindly to huge documents.
However, I find that Numbers and Pages for Mac OS to have a sweetly intuitive way of doing what I want.
Regards,
Ian.

How to Read data from excel file without converting a excel file into .csv or any other format

Hello,
Can somebody suggest me how to read from an excel file (consisting of 10 work sheets) to an array?
Thanks,
She

You have to be careful when using the spreadsheet-files vi's. They are located in the Functions Palette under File IO, you will find "Write To / Read From Spreadsheet File.vi"s.
Here is what the Context Help says about the vi function:
"Reads a specified number of lines or rows from a numeric text file beginning at a specified character offset and converts the data to a 2D, single-precision array of numbers. You optionally can transpose the array. The VI opens the file before reading from it and closes it afterwards. You can use this VI to read a spreadsheet file saved in text format. This VI calls the Spreadsheet String to Array function to convert the data. "
This is quick & easy when the spreadsheet is all the same format. You can set the format to string as well. HOWEVER... you do have to convert the Excel spreadsheet to text before using it.
I haven't experimented with the Active-X, but it may look as the way to go if you have combination text / numeric values in the spreadsheet.
If you did convert it to text, then you can use array functions as well and treating the file as an array of strings (see very brief example attached). The example is to illustrate a point only

hi,
everyone, i meet a problem.i want to write a excel
el file use java.i can use .csv input the date to
excel.but i want to know how to format it.
thanks
JoveIf I understand your question correctly you need to know the format of a .csv file for use in an Excel spreadsheet. A .csv file is a comma-delimited file so all that you need to do is write your data elements to the file with commas in between them. Having done something similar in the past, let me warn you that when Excel is reading your file, it uses some characters other than commas as field delimiters. for example, / : and ; are treated as commas. To defeat this, you will need to surround fields containing those characters in double quotes.
Hope that helps
Mark
