Problem in reading excel file

Hi All,
I have a requirement to read records from an excel to an internal table.I am using FM
KCD_EXCEL_OLE_TO_INT_CONVERT to read excel.
My problem arises when the program comes across a cell which contains some formulae assigned to it.
The FM does not read the value in the specified cell and throws a runtime-error.
Please help me out .
Thanks and regards

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

Problem with an excel file

Dear All,

Could you help me?
thanks

Hi,
You may end the Excel process first, the “PsTools” have a pskill command that you can use to end a process remotely.
Here’s a simple command:
pskill \\computer –u username -p password excel.exe
For more information, please see the KB below:

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);

Problem While reading a file in text mode from Unix in ECC 5.0

Hi Experts,
I am working on Unicode Upgrade project of ECC5.0.
Here i got a problem with reading a file format which it does successfully in 4.6 and not in ECC5.0
My file format was as follows:
*4 000001862004060300000010###/#######L##########G/##########G/########
It was successfully converting corresponding field values in 4.6:
*4
00000186
2004
06
03
00000010
25
0
4
0
54.75
0
54.75
0.00
While i am getting some problem in ECC5.0 during conversion of the above line:
*4 000001862004060300000010###/#######L##########G/##########G/########
it was consider in the same # values.
I have used the following statement to open and read dataset.
OPEN DATASET i_dsn IN LEGACY TEXT MODE FOR INPUT.
READ DATASET i_dsn INTO pos_rec.
Thanks for your help.
Regards,
Gopinath Addepalli.

Hi
You might be facing this problem because of uni code. So while opening or reading the file, there is a statement call ENCODING. Use that option and keep the code page which you want. Then the problem may be solved.
Thanks & Regards.

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.

Umang Mehta

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.

Problem while reading multiple files through FTP Adapter

Hi,
We have a requirement to read the excel files placed in an FTP Location and as there is no Adapter to read Excel file
we are using FTP Adapter and reading the Header values of the file(name of the
file) and we are paasing as input to the Java code which will read the data nd insert into the Database.
If we place above 20 files it was reading only some files and some were left and if we delete the files and place the unread files again some files are read and if we do the same procedure then all the files were read.
Any help regaring this appreciated.
Thanks and Regards,
Nagaraju .D

Are you doing anything complex for your polling, e.g. Files that must be n time old.
Can you post the WSDL so I can see the polling configuration. I only need to see the adapter configuration, not the whole file.
cheers
