Reading Excel in PI

Hi,
Working on a interface to read excel file.
Referring the usual blog to read .xslx/.xlsm file.
I understood the use of module parameter . Now my question is how to create the data type.
Will it be just like the data type we create for normal interfaces or it will be like the xml of sheet1.xml got after unzipping the .xlsm file.
Thanks,

Hi Apu,
the blog says
This way our mapping will receive all data from the sheet in an XML format. The only thing that's left is to create an XSD file from the XML file we received in order to be able to use it in the mapping and as our Service Interface and we can proceed with mapping
First you finish the module configuration and run the scenario. it will generate the xml. but it can fail as you don't have the xsd.
From generated xml you can created xsd.
there are some online tools available to convert xml to xsd. then you can use that xsd for your scenario.
Regards,
Muni.

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

How to read Excel file in flex

Hi,
     I am new to Adobe flex and i dont know how to read Excel in flex and i need coding for that. So anybody help me...
thanks in advance...

Hi
You can read and parse XLS files (only works with xls-files) with urlloader and a ZIP-lib that can read zip-files.
public function loadXLS(url:String):void
            var urlLoader:URLLoader = new URLLoader();
            urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
            urlLoader.addEventListener(Event.COMPLETE, onLoadComplete);
            urlLoader.load(new URLRequest(url));
        private function onLoadComplete(even:Event):void
            urlLoader.removeEventListener(Event.COMPLETE, onLoadComplete);
            model.sheetsDict = new Dictionary();
            var zipFile:ZipFile = new ZipFile(urlLoader.data);
            for(var i:int = 0; i < zipFile.entries.length; i++)
                var entry:ZipEntry = zipFile.entries[i];
                var data:ByteArray = zipFile.getInput(entry);
                if(useFile(entry.name, "/sheet([^$]+)"))
                    model.sheetsDict[entry.name.split("xl/")[1]] = new XML(data.toString());
                else if( useFile(entry.name, "/sharedStrings.xml") )
                    model.sharedStrings = new XML(data.toString());
                else if( useFile(entry.name, "/workbook.xml$") )
                    model.workbook = new XML(data.toString());
                else if( useFile(entry.name, "/workbook.xml.rels") )
                    model.rels = new XML(data.toString());
            trace(model.sharedStrings)
to read the xml properly you have to use namespaces in the reader-class
namespace ns1 = "http://schemas.openxmlformats.org/spreadsheetml/2006/main";
        use namespace ns1;
        namespace ns2 = "http://schemas.openxmlformats.org/officeDocument/2006/relationships";
        use namespace ns2;
        namespace ns3 = "http://schemas.openxmlformats.org/markup-compatibility/2006";
        use namespace ns3;
        namespace ns4 = "urn:schemas-microsoft-com:mac:vml";
        use namespace ns4;
        namespace ns5 = "http://schemas.openxmlformats.org/package/2006/relationships";
        use namespace ns5;

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.

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.

How to Read Excel Work Sheet Name

Hi
I am try to read Excel sheet from SAP B one. any one tell me how to get the Sheet name through Programmatically in C#....
Senthil Kumar

There are two ways you can do that:
#1
A - put the budget.htm file on your server where you can link to it.
B - on the web page add an HTML snippet with the folloiwng code:
<iframe height="XXXpx" allowTransparency="true" frameborder="0" scrolling="no" style="width:XXXpx;border:none" src="URL TO BUDGET.HTM FILE"></iframe>
Set the width and height, in pixels, so that the snippet will display the entire table.
#2
A - open the budget.htm file with a text editor and copy all of the code.
B - add an HTML snippet to the iWeb page and paste the code into the snippet.
An example of both methods are near the bottom of this demo page: Tables.
With method 1, you can edit or change the table without having to use iWeb. Just replace the budget.htm file with the new and improved version on the server. That will automatically be seen in the published site.

ODI reading Excel via ODBC on Linux

I've got ODI loading data from Excel via ODBC with everything running on Windows, and it runs fine!
But will this work when I run ODI on a Linux platform? Will I have to buy some kind of ODBC driver for Excel under Linux? Has anyone done this before?
Any help gratefully received!
Thanks
A

There exists a native JDBC driver for excel, it is a sourcefourge project. This allows you to read excel data irrespective of platform through JDBC rather than having to use the JDBC/ODBC bridge.

DI: Unable to read Excel source

Hi,
We use BusinessObjects Data Services XI 3.1, version 12.1.1 on UNIX Server.We have created BoExcelAdapter to read Excel source and we were not facing any issues in reading the Excel files so far.
Yesterday when we ran the job to read a new excel file, we received the error message 'Could not find worksheet ... in file ..'.
But the excel file has the specified worksheet.
Could you please guide me as to what has caused such an error and how to resolve this.
Thanks,
RaajMahee

Hi RaajMahee
Cause
On Unix, the excel adapter uses the apache poi browser to read the spreadsheet.
When the adapter tries to open the spreadsheet with the poi api, the poi api chokes and gets an exception of ArrayIndexOutofBound.
POI library does not support a feature found in the workbook
Resolution
This problem had already been addressed in the latest poi patch release, poi-3.2-FINAL-20081019.jar.
1. Download the attached file poi-3.7-20101029 and rename it to poi-FINAL-3.7-20101029.jar
2. Copy the poi-FINAL-3.7-20101029.jar file to your $LINK_DIR/lib directory of your Unix/Linux server.
3. Through the Data Services Management Console, stop the excel adapter.
4. Using the Data Services Management console, modify the Excel Adapter's class path and replace the reference to poi- 2.5.1-final-20040804.jar with its full path with poi-FINAL-3.7-20101029.jar with its full path.
5. Save and restart the adapter.
6. Try again processing the Excel file with formulas.
if you want to download the poi-3.7-20101029 file just follow the link
[https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/sno/ui_entry/entry.htm?param=69765F6D6F64653D3030312669765F7361706E6F7465735F6E756D6265723D3132393634353426]
if you are unable to access this link(Why because it ask login credentials) just put your e-mail and i will send the zip file.
