Reading XML file using BAPI I must use adapters .

Reading XML file using BAPI and then uploading that xml file data into SAP using BDC.
I cant take file on to my Application server I am getting the file dynamically from other file server and I need to use BAPis to read data from XML file.please tell me what should be my Import,Export and Tables parameterrs should be.
Thanks

Hi,
Import, export and table parameters for BAPI is required, without that BAPI will not able to collect the data from XML. What you need to do is write a Zprogram and collect the data, store that data in internal table and call the BAPI by passing required parameters.
Different Scanarios:
1) Before calling a BAPI write some other program which collects the data from XML and create a UNIX file. Try to get the data from UNIX FILE
2) If you see the XML tags, data will be in side that tags, try to get the data from XML tags and store that data in one SAP table. You can use the BAPI by fetching the data from table
3)Create a table and store the data in the table. Use the table in SAP to extract the data.
BAPI won't work without any parameters, you have to pass some parameters then the BAPI will return some values.
Hope i am clear.
Thanks&Regards,

How to read HTML files using UTL_FILE

Hello Friends,
How to read HTML files using UTL_FILE package ? According
to Oracle documentation UTL_FILE can read or write OS Text Files.
Thanx in advance..
Adi

HI Hareesh,
i have gone through that blog.
i tried it...but i am getting mapping error no receiver determination fond because there are so many excel files.
my data is available on sharedString.xml but also it is in not same order.
i have no clue how to handle this part form the blog.
"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. As you can see from the sheet.xml files all the data is placed with column name and row number so it's not that difficult to map it to an table type format using the Message Mapping only (no java, abap mapping required)."

Is it possible to read the file using File Adapter which is in client machi

Is it possible to read the file using file Adapter which is in client machine(on the same network).Then what is thee need of FTP Adapter?

You can achieve that by exposing your client machine as a drive, then you can go using file adapter.
FTP adapter will help you to communicate with different machine which is in different network.
It is considered good etiquette to reward answerers with points (as "helpful" - 5 pts - or "correct" - 10pts).
Thanks,
Vijay

How to read 835 files using ssis

Hello Everyone,
It is possible read 835 files using ssis.
Please share your suggestions on this.
Regards,
Vaishu

Hi Vaishu,
None of the canned (standard) SSIS tasks let you do so.
But if you can buy http://www.cozyroc.com/ssis/edi-source (I am not anyhow affiliated with CozyRoc) it states it can read ERA (AKA 835) files. CozyRoc lets you run it for free in Dev.
If there will be a decision not to buy then you can simply crate a transformation out of several manipulations or by creating a custom SSIS component or some other programming methods need to be used.
PS: Again, I just know CozyRoc quality of components is awesome, but I do not make any profit from referring to it.

I am unable to read pdf files using Acrobat Reader on my MAC OS X. Any suggestions?

How do I read pdf files using my MAC OS X?

You can read pdf files with preview. Select a pdf document, right click on it, and choose Preview. You can also get info and select to choose Preview for all.
You can also install Adobe Reader 10.1.3 for Lion. It will also install a plug-in to read pdf docs in the browser.

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.

File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

To read text file using utl_file

I would like to read test_file_out.txt which is in c:\temp folder.
create or replace create or replace directory dir_temp as 'c:\temp';
grant read, write on directory dir_temp to system;
then when i execute the below code i get the error .
// to read text file using utl_file
DECLARE
FileIn UTL_FILE.FILE_TYPE;
v_sql VARCHAR2 (1000);
BEGIN
FileIn := UTL_FILE.FOPEN ('DIR_TEMP', 'test_file_out.txt', 'R');
UTL_FILE.PUT_LINE (FileIn, v_sql);
dbms_output.put_line(v_sql);
UTL_FILE.FCLOSE (FileIn);
END;
ERROR:
invalid file operation
i would like to use ult_file only and also can you let me know to read the text file and place its contents in tmp_emp table?

Are you trying to read the contents of the file into the local variable? Or write the contents of the local variable to the file?
Your text talks about reading the file. And you open the file in read mode. But then you call the UTL_FILE.PUT_LINE method which, as SomeoneElse points out, attempts to write data to the file. Since the file is open in read-only mode, you cannot write to the file.
If the goal is really to read from the file, replace the UTL_FILE.PUT_LINE calls with UTL_FILE.GET_LINE. If the goal is really to write to the file, you'll need to open the file in write mode ('W' rather than 'R' in the FOPEN call).

To do that you need to get the response output stream and write yur file contents to that.
response.setContentType(mimeType); //Set the mime type for the response
ServletOutputStream sos = resp.getOutputStream();
sos.write(bytes from your file input stream);
sos.close();

Can't read text file using UTL_FILE

Hi All,
how can I read notepad file using UTL_FILE package.I have specified the UTL_FILE_DIR in the init.ora file.My objective is to when a button is clicked, the contents of the file will display in a text item.Here is my code written in WHEN_BUTTON_PRESSED trigger.
DECLARE
     file_handle UTL_FILE.FILE_TYPE;
data_line Varchar2(100);
BEGIN
     file_handle := UTL_FILE.FOPEN('E:\vimal','abc.txt','R');
          message('directory created');
     UTL_FILE.GET_LINE(file_handle, data_line);
     :block2.t1 := data_line;
     UTL_FILE.FCLOSE(file_handle);
END;

Why don't you use text_io? Don't forget that UTL_FILE is reading directories from the database point of view. The E drive for the database is a different E then on your client pc. I presume your database is on a different computer. Are you getting any errors?

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 );

Can't read a file using FileInputStream(String path)

Hi,
Platform: Fedora Core 3
IDE: MyEclipse 3.8.1
Servlet Container: Tomcat 5
Framework: Struts 1.1
JDK: 1.5
1) I'm trying to read a file (mw.properties) which resides in the package aaa.ccc.uuu.struts using FileInputStream("/aaa/ccc/uuu/struts/mw.properties");
The class (named MyAction) trying to read this file is in the following package
aaa.ccc.uuu.struts.actions.MyAction
2) The alternatives that I've tried is:
a) FileInputStream("aaa/ccc/uuu/struts/mw.properties");
b) FileInputStream("aaa/ccc/uuu/struts/mw.properties");
c) FileInputStream("/mw.properties");
d) FileInputStream("mw.properties");
(/javaweb is the context path)
e) FileInputStream("/javaweb/WEB-INF/classes/aaa/ccc/uuu/struts/mw.properties");
f) FileInputStream("/classes/ccc/uuu/struts/mw.properties");
g) FileInputStream("classes/aaa/ccc/uuu/struts/mw.properties");
h)FileInputStream("/usr/local/jakarata-tomcat-5/webapps/javaweb/aaa/ccc/uuu/struts/mw.properties");
i) FileInputStream("/WEB-INF/classes/aaa/ccc/uuu/struts/mw.properties");
...and so forth.
3) My Tomcat directory structure looks like the following:
javaweb
-->src
---->aaa
------>ccc
--------->uuu
------------>struts/mw.properies
--------------->actions/MyAction.java (trying to read the mw.properties file from within this file)
-->web
--->WEB-INF
----->classes
--------->aaa
------------>ccc
---------------->uuu
------------------->struts/mw.properties
----------------------->actions
--------------------------->MyAction.class (I've placed the mw.properties file here as well)
----->jsp
------>some more folders
Note that the mw.properties file is in the source directory as well as the classes directory - I did this to trouble shoot. As far as i know the correct place to put the mw.properties file is in the classes folder (taking into consideration the package structure obviously)
I'll appreciate any help I'm really stumped! (Not sure if this is the correct forum to post this query)
Cheers

Hi,
My knowledge about web applications is very limited. I would try to create a new file from the app using just a name, and not a path. I would then look for the created file to see where the current path is. But I guess you could figure it out by reading the documentation.
