Java API for reading Excel Files.

Hi,
Can you please suggest me any api for reading excel files.
Right now i am using jxl.jar for this purpose but i am searching for an open source java api better than this.
Whether POI gives better than this ?

Jar files required to read excel file in SAP PI 7.3.1 sp09 dualstack

Hi experts,
I need to read excel file (.xls) using SAP PI and process it to target system. I have read blogs
and found that there are 2 ways to read an excel file in PI using file adapter.
1) Developing a custom adapter module
2) Using XSLT code.
So in order to develop a custom adapter module, i have followed the following blogs
**************** - XI - Step-by-step guide to develop Adapter Module to read Excel file
and
Excel Files - How to handle them in SAP XI/PI (The Alternatives)
and
http://wiki.scn.sap.com/wiki/display/ABAP/Adapter+Module+To+Read+Excel+File+with+Multiple+Rows+and+Multiple+Columns
I am unable to find the jar files in SAP PI at OS level as per the first blog(think they were obsolete).
Please let me know
1) What are the required jar files needed to read excel file and their location
2) Even if i use the old jar files as mentioned in the first blog can i achieve my requirement
3) Following this blog Convert incoming XML to Excel or Excel XML – Part 1 - XSLT Way if i apply the same logic at sender side, will it work? Because through case studies i came to know that we cannot read a .xls file using XSLT code. Correct me if i am wrong.
Looking for your valuable suggestions.
Regards
Shilpa

Hi Shilpa
Welcome to SCN!
The blog you refered to might be for previous versions of PI. You can refer to the following two wikis to find out what are the relevant JAR files for PI 7.3 and also how to get them.
XI libraries for development - Process Integration - SCN Wiki
Where to get the libraries for XI development - Process Integration - SCN Wiki
It also looks like for newer versions, you might not need to manually get and add those JAR files into your NWDS project - please refer to the first comment on the blog below. I have not tried it personally as I'm not using the latest NWDS, but you can try that first, and if it does not work, then go get them manually.
PI 7.4 - Adapter Module Creation using EJB 3.0
Do note that you should be using the JAR files that is corresponding to your PI server version.
As for your third question, that does not apply to you. XLS is the older non-XML format, and therefore cannot be read by XLST since it is in binary format.

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 );

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" );

Error while reading excel file from application server into internal table.

Hi experts,
My requirement is to read an excel file from application server into internal table.
Hence I have created an excel file fm_test_excel.xls in desktop and uploaded to app server using CG3Z tcode (as BIN file type).
Now in my program I have used :
OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
DO.
READ DATASET v_filename INTO wa_tab.
The statement OPEN DATASET works fine but I get a dump (conversion code page error) at READ DATASET statement.
Error details:
A character set conversion is not possible.
At the conversion of a text from codepage '4110' to codepage '4103':
- a character was found that cannot be displayed in one of the two
codepages;
- or it was detected that this conversion is not supported
The running ABAP program 'Y_READ_FILE' had to be terminated as the conversion
would have produced incorrect data.
The number of characters that could not be displayed (and therefore not
be converted), is 445. If this number is 0, the second error case, as
mentioned above, has occurred.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_CONVERSION_CODEPAGE', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
Characters are always displayed in only a certain codepage. Many
codepages only define a limited set of characters. If a text from a
codepage should be converted into another codepage, and if this text
contains characters that are not defined in one of the two codepages, a
conversion error occurs.
Moreover, a conversion error can occur if one of the needed codepages
'4110' or '4103' is not known to the system.
If the conversion error occurred at read or write of screen, the file
name was '/usr/sap/read_files/fm_test_excel.xls'. (further information about
the file: "X 549 16896rw-rw----201105170908082011051707480320110517074803")
Also let me know whether this is the proper way of reading excel file from app server, if not please suggest an alternative .
Regards,
Karthik

Hi,
Try to use OPEN DATASET v_filename FOR INPUT IN BINARY mode encoding default. instead of OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
As I think you are uploading the file in BIN format to Application server and trying to open text file.

Function module for transfering a file contents into another?

Hi all,
Is there a Function module for transfering a file contents into another?That is the whole content from a file to other??

Hi,
I think there is no such FM. You need to read the data in internal table and then write it in another file.

Reading excel files in real time

Hello,
I would like to have a labVIEW program which permits to read several excel files, and collect all data in a single excel file.
I know that it is possible to write a program which can read multiple files.
But I would like to know that if its possible to read files in a real time:
for ex. each time there is a new excel file to read, the LabVIEW program read it automatically and add its data to the final file?
Thank you and bests regards

As Sam notes, it is certainly possible to merge Excel Files (I've done it, myself). An oft-repeated Best Practice for Program Development, which I didn't understand nor start following until quite recently, is "Write the Documentation First". In this case, you want to think carefully (and specify in a Document, which tends to "clarify your thinking") a number of issues:
Where will you look for the Excel Files to be merged? [Hint -- it's much easier if they are all in the same Folder).
Where will you save the Merged File? Will it be in the same Folder as the Source Files?
How will the Merged File be named? This can have an interaction effect with the previous points.
What is the structure of the Source, and of the Merged, File? Is it "obvious" how the Merge is to take place?
Related to #4, are there Headers? Multiple WorkSheets?
How do you know when it is time to Merge? Are you checking for new files periodically? How often?
In some ways, these "structure" questions are trickier to design and thornier to deal with than simply reading data from two Excel Files and writing the data to a third (which I'm calling a Merge). Note that I'm assuming that you are really dealing with Excel files (.xls, .xlsx), for which I recommend using the Report Generation Toolkit. If you are speaking about Comma-Separated Variable (.csv) files that LabVIEW calls "Spreadsheets", the above questions are still mostly relevant, but your approach will be a little different.
Write yourself a Document, show it to us, and if you have ideas on how to do this, give it a try and show us your code -- we'll try to provide assistance if you "get stuck".

Read Excel file path in WD

Hi,
We want to read a excel file. For that we are using file upload UI element and HSSF POI to read excel file. The code to read the excel file is working fine in standalone. In standalone we are hardcoding the file path. But in WD application, we are not hard coding it.
We are using following code to supply the file name to HSSF code through file upload UI:
try
         InputStream in = new FileInputStream(wdContext.currentContextElement
                                           ().getFileResource());
         wdComponentAPI.getMessageManager().reportSuccess("IN "+in);
         HSSFWorkbook wb = new HSSFWorkbook(in);
catch (Exception e)
     wdComponentAPI.getMessageManager().reportSuccess("ERROR in HSSF");
Where FileResource is a context variable binded with property "data" of FileUpload UI element.
Now, the problem is that the excel file is not getting read. We are getting ERROR in HSSF message.
Please help in reading the file path.
Regards,
Vaibhav

Hi,
   Try this:
InputStream in = wdContext.currentContextElement().getFileResource().read(false);

Satyajit.

Open module for managing property file and environment variables

Looking for an open module for managing property files and environment variables (like CLASSPATH) set in a shell script. For handeling properties (preserving comments, supporting includes, appending new entries, and more) I have looked at SuperProperties from openadaptor but find certain functionality lacking. As for interfacing with common shell scripts/files containing setting for CLASSPATH, JAVA_HOME, other system/application variables another type of object editor is needed. Maybe JFIG?
Any ideas are greatly welcomed.

You seem wright, you hit a brick wall here with Air to find the location
of the command console on windows...
So in fact I never build an exe tool, but this little problem was a nice
case to test it and I tried it.:
I downloaded monodevelop
-GTK# for .NET 2.12.10*
-MonoDevelop 2.4.2*
from http://monodevelop.com/Download
created a console project and had an exe in 5 minutes !
You can download the findconsole tool and the projectfiles here:
http://greencollective.nl/temp/dump/findconsole_monoproject.zip
findconsole.exe will reveal the path/location of cmd.exe on a windows system.
Cheers,
