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 );

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.

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" );

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);

Rename files using text or excel file

I am trying to find out how to rename files on my pc using the names stored in a text document
eg. the file on the pc is called "C07_08.dat"
the text file has the following line "3am Eternal KLF 03:15 121 BMG C07.08"
i want to change the name of the file "C07_08.dat" to "3am Eternal.mpeg"
What I would like is a batch file or program or something that will see the text "C07.08" and find the corresponding file "C07_08.dat" and rename it "3am Eternal.mpeg"
I have managed to create a excel document that has the information in four separate columns
Column A has the name of the file I want to use (ie. 3am Eternal) Column B & C have unneeded information and Column D has the file reference (ie. C07.08)
I was told that Python or Visual basic could do this so I downloaded them but I have no experience with this so im lost as to what to do, I have over 1800 of these files so doing it file by file will take quite a while.
I have included a sample of the text file for reference if that helps

Here are two VBScripts that will rename the files based on the text file example you provided. The script that reads a
TEXT FILE requires each entry to be separated by
ONE TAB because it is the
TAB
that it uses to split each line into 4 parts (part1 - old file name, part2 and part3 - items you don’t need, part 4 - new file name). If there is more that one tab then the Split Function will not work properly.
The second VBScript will read the
EXCEL FILE row by row and use the values in Column A for the old file name and
Column D for the new file name. This approach will work much better if you have an excel document setup like this.
I used your example that you provided and it test fine for both approaches.
'Read text file
Dim objFSO, objFolder, inFile, strInLine, strOldFile, strNewFile
Set objFSO = CreateObject("Scripting.FileSystemObject")
'Select the folder
Set objFolder = objFSO.GetFolder("C:\Scripts\MusicFiles")
'Open Text File
Set inFile = objFSO.OpenTextFile("C:\Scripts\MusicFiles.txt",1)
Do Until inFile.AtEndOfStream
'Read text file line by line and Split each line into 4 parts.
strInLine = Split(inFile.ReadLine, vbTab)
'Old File name
strOldFile = strInLine(3)
'new File name
strNewFile = strInLine(0)
'Loop through the files in the folder

I saved my Form Central spreadsheet file once as a excel file but it will not allow me to save it a second time as an excel file. It says that I cannot complete this action because the file me be open in another application, but it is not open in another

I saved my Form Central spreadsheet file once as a excel file but Forms Central will not allow me to save the file a second time as an excel file. I am informed that I cannot complete this action because the file me be open in another application, but it is not open in another application. What is the problem, and how do I solve the problem. Thank you. Jeff

First check the version of the document with Jongware's script "Identify.jsx" (ExtendScript/JavaScript).
You can find it here:
[Ann] Identify Your InDesign File
If it is CS 5.5 or above, you need someone to open it in the version the script says and export an IDML representation from that. Another way would be to install a 30days version of CS6 or above (CC) and do it yourself.
In regards of the script showing a result for InDesign files higher than CS6:
CS7 = CC v9
CS8 = CC v10 = CC-2014 or CC2014.1

CSV files to a single excel file

Hi All!
I would like to ask regarding the conversion of CSV files into a single Excel file.
I am planning to combine all my 8 csv files into a single excel file being separted by sheets. each csv file will be converted in to a worksheet and be added to the excel workbook file.
Any idea? I've heard about POI but i don't see any documentation for java beginners and simple example program that will convert CSV --> Worksheet and add that worksheet to an excel file.
Thanx,
MaDz
