Adapter Module (Reading Excel File)

Hi Guys,
I followed the Webblog : Read Excel instead of XML through FileAdapter
For File Adapter Module Development , for reading Excel Sheet.
Deployment all went fine and when i used in my configuration , file is getting picked up but the xml content is not getting displyed , it says not well formated.Below error is shown in the CC Monitor
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
XML document must have a top level element. Error processing resource 'http://pxxxxx:50xxx/mdt/messagecontentservlet?att...
My coding in nwds
 xmldata = "<?xmlversion="1.0"encoding="UTF-8"?>
 + "<ns:"+wb.getSheet(0).getCell(0, 0).getContents() +"xmlns:ns=""
 + wb.getSheet(0).getCell(1, 0).getContents() + "">"
 + "<Name>"+ wb.getSheet(0).getCell(1, 2).getContents()
 + "</Name>" +"</ns:" wb.getSheet(0).getCell(0, 0).getContents()">";
Kindly suggest if any

Problems with Adapter module converting Excel file to XML

Hi All,
I have created an adapter moduel to convert the input excel file to XML and have deployed it. While testing we found that there is an extra empty record with empty elements added additionally. Can anyone help on this?
Below is the convert function used for it.
public byte[] convert(byte src[],String msgType,String nameSpace) throws Exception
 String xmldata = "";
 try
 ByteArrayInputStream byteArr= new ByteArrayInputStream(src);
 Workbook wb = Workbook.getWorkbook(byteArr);
 Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"AO: Conversion Started.");
 xmldata ="<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n\n"+ "<ns0:"+msgType+" "+"xmlns:ns0=\""+nameSpace+"\">";
 Cell[] cells ;
 Cell[] cellNames ;
 cellNames = wb.getSheet(0).getRow(4);
 for(int j=5;j<wb.getSheet(0).getRows();j++)
 xmldata = xmldata+"<Record>";
 cells = wb.getSheet(0).getRow(j);
 for(int i=1;i<wb.getSheet(0).getColumns();i++)
 xmldata = xmldata+"<"+cellNames.getContents().replaceAll(" ","")+">"+cells.getContents()+"</"+cellNames.getContents().replaceAll(" ","")+">";
 xmldata = xmldata+"</Record>";
 xmldata = xmldata + "</ns0:"+msgType+">";
 wb.close();
 catch (Exception e)
 Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"AO: Exception in Convert Method.");
 return xmldata.getBytes();

Hi,
xmldata = xmldata+"<Record>";
cells = wb.getSheet(0).getRow(j);
for(int i=1;i<wb.getSheet(0).getColumns();i++)
xmldata = xmldata"<"cellNames.getContents().replaceAll(" ","")">"cells.getContents()"</" ","")">";
xmldata = xmldata+"</Record>";
Can u please change this part of code as
Hi,
cells = wb.getSheet(0).getRow(j);
if(cells.size()>0)
xmldata = xmldata+"<Record>";
for(int i=1;i<wb.getSheet(0).getColumns();i++)
xmldata = xmldata"<"cellNames.getContents().replaceAll(" ","")">"cells.getContents()"</" ","")">";
xmldata = xmldata+"</Record>";
Check first if the row is empty...
im nt sure it is cells.size() or cells.length.. please try both
Thanks & Regards

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.

Adapter Module for Sender File Adapter to access a Flat file

Hi,
We have a scenario where the source is a flat file.I want to develop an Adapter Module to make a small change to every line in the Flat file.
Now how do we read a flat file in the Adapter Module?Coz the flat file will be converted to XML file by the Standard Adapter Module of the File adapter.
Please help me out with this.
Thank you,
Anu.

Hi Anu,
If you are not using Content Conversion option Standard Adapter Module does not convert the Flat file to XML .
You can directly access the payload as it is in flat file in the Adapter Module and make changes.
Use the Standard classes ModuleData & moduleContext to fetch the Payload.

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

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.

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);

Adapter Module Filename in File Receiver Channel

Hi All,
is it possible to set the Filename in File Receiver Adapter from Adapter Module?
I know that it is possible to read the data
Channel ch = new Channel(moduleContext.getChannelID());
path = ch.getValueAsString("file.targetDir");
I Need to set the filename in Adapter Module, using of Payload is not possible because Payload is not xml.
Dynamic Parameters in Message Header is not possible because it is an multi mapping process an i need dynamic Filename for each Part
payload after mapping is like
MainDocument
SubMainDocument
MainDocument
SubMainDocument
i need special Name for each SubMainDocument in FileReceiverAdapter
regards
ralf

Hello Stefan,
interface mapping is an mapping like this:
outbound_interface => Inbound_Interface1
                             => Inbound_Interface2
                            => Inbound_Interface3
in sxmb_moni this looks like this
Soap_Header
Soap_Body
Payloads
     =>MainDocument ( application/xml )
    => SubMainDocument ( text/xml )
     =>MainDocument ( application/xml )
    => SubMainDocument ( text/xml )
First SubMainElement is routing to FileReceiverAdapeter A   where Filename has to be like "NameA%nr%"
second SubMainElement is routing to FileReceiverAdapeter B   where Filename has to be like "NameB%nr%"
%nr% is som value from the Payload.
Payload is not xml because using of Conversion Argent!!
I Think there is only one Dynamic in Header for all subelements, i have test it!

Adapter module to enhance File adapter

Hey guys
i need a small clarification regarding adapter modules.
is it possible via adapter modules to enhance the File adapter to such an extent that it can deliver files to two separate systems in separate landscapes.
i know i can design one more receiver determination and can also use Run OS command options,but modules in general give better performance compared to others so just wan't to explore a little bit more about them.
Thanx
Aamir

Hey Aamir,
yeah, they do take a lot of resources, but that's how XI was built to work.
What you're trying to do is a workaround and may not get support from SAP.
If I have understood right, you still wanna maintain the endpoint connection data in the communication channels but want to acces them directly without going through the technical routing pipeline, is that so?
If that's it, I'm sorry but I cannot help you any further.
The only way I know of accessing adapters without going throught technical routing is by using lookup API (RFC, JDBC, Soap) but it is not intended for endpoint scenarios (insert, update etc), mainly for simple read (lookups).
If maintaining the connection data outside adapters is not a concern, you could try to create the connections directly in Java code, inside java proxies.
Regards,
Henrique.

Adapter module that dumps file to XI file directory

I am given a task to find a way of backing up files the simpliest way. Currently, our config is in a scenario where there are 2 receiver, the receiving system (SAP) and the file backup (File adapter). I would want to reduce the config requirements by eliminating the file backup objects. And I am thinking of doing this by creating an adapter module to be included in the sender adapter.
Another idea I could think of is the adapter module calls upon the file comm channel to do the file backup.
The purpose of this research is to reduce object transport time and the mistakes the transport guys are doing on the file comm ch reconfiguration.
To those who have experiences with adapter module development, is this idea feasible?

Hi Jai,
Thanks for your reply. That is the 2nd option I have in case the 1st one isnt possible.
To further elaborate,
Current config:
we have two AS2 comm channels (sender and receiver) managing the connection with our external partners.
File comm channels to backup the files we send and receive.
The problem:
We are having problems with the transport guys as they often make mistake on reconfiguring the file comm channel during transport.
Requirements:
Reduce object creation and tranport time.
Solution proposal 1:
The idea is to remove all existing objects related to file back up and have all the file back ups done by the adapter module. And this adapter module would become part of the as2 comm channels module processes.
Hope this clarifies things more.
