Read/write file located on server

Hi,
I want to read a TXT file located on server and depending on the response I want to write an XML file also located on server
how could be it possible in JAVA
please help me
alpesh

the TXT file is located on the WEB server, and I want
to read the TXT file's content From the client, I assume. URLConnection. Or your favorite browser.
the content is the User InformationAnd you want to write that on the server. Forget it, unless you have CGI or FTP or a servlet or whetever to process incoming requests or allows you to connect to the fie system somehow (WebDAV).

How To read/write file on remote server in java

Hi All,
How To read/write file on remote server in java? I mean using URL - http://www.xyz.com can I right file to that perticular server.
Thanks in advance

If your server support a means of uploading files you can.
A popular means is [http://en.wikipedia.org/wiki/WebDAV]
However, by default web server don't allow you upload files, its usually something you need to configure or install.
I suggest you have a look at your web servers documentation.

Applet can't read local file on web server, security issue!

There is any way to read/write files of web server through the applet except the Signed Applet.
If any idea the reply me soon.
Thanks in advance

Applets are downloaded from web servers and execute on the client machine.
Therefore they have no access to the web server file system, signed or not.
They could have access to the client file system (the machine where they run),
but for security reasons only signed applets have this privilege.
So to answer your question, you sign if you want to access client files.
To access web server files, you don't need to sign the applet, but you need
to provide some method of accessing files remotely, for instance:
- Files published for the web can be read using HTTP
- Files can be read or writen with the help of an FTP server on the same machine as the web server
- A servlet running on the HTTP server can collaborate with your applet to exchange files

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.

Help with utl_file (read/write file from local directory)

Need help reading/writing file on local machine from plsql using 10.2 DB.
I am trying to read/write a file from a local directory(laptop) without success.
I have been able to read/write to the database server directory but can't write to directory on local machine.
The utl_file_dir parm has been set to * and the db restarted but I can't get it to work... Here's the plsql statement.
out_file := UTL_FILE.FOPEN ( 'C:\PLSQL', 'TEST.TXT', 'W' ,32767);
Whenever I run it continues to write to c:\PLSQL dir on the database server. Have looked at the "Directory" object and created MY_DIR = C:\PLSQL but it writes to the db server.
Running 10.2 on a remote windows server, running PLSQL using sql*navigator.
Thanks in advance for your help..

I don't see how you expect the server to be able to see your laptop across the network, hack into it and start writing files. Even if it could, what if there is more than one laptop with a C: drive? How would it know which one to write to?
Is there a shared drive on the server you can access via the laptop?

Not recognizing # while reading the file from application server

Hi
I am reading a file from application server. While reading into internal table with read statement the last field in each record is filling with hash symbol in the last digit. If I write any if condition with HASH symbol its not going inside the if condition, means its not recognizing as hash may be its internally treating as some other. I need to remove the hash from that field. How I can do that.
Thanks,
kishore

I faced exact situation. Yes, internally its treated as some other special character. What i did was, becuase hash symbol was always coming at the end...i created a dummy field in my internal table so that it will not interfere with my actual data. When i see the data in my internal table, the hash always falls in the last field (dummy) which i will ignore. I could not get solution to remove this hash so i adopted this approach and it worked!!
Hope it helps,

How to open a file located at server using JSP

hi,
i would like to open a file located at server as it is. I mean to say, if it a MS Word file, i wanna open it in MS Word, if it an Excel file, i wanna open it in Excel. i know the location (path) of the file. Can someone help me please.
Thanx

The best way would simply be to HREF it.
ie<a href="excelfiles/spreadsheet.xls">Open spreadsheet</a>When a user then clicks on that lick in their browser they should be given the option to either download or (if they have the appropriate program, in this case MS Excel, installed) open it.
This works best if the client is using a version of Internet Explorer (if you're dealing with MS files), but any browser should potentially offer you the option of opening the file.
Beyond that there's no way to specifically open a program on a client machine (it'd be a bit of a security loophole if you could! - Imagine a JSP page being able to open FDISK...). All you can do is pass the file (via the HREF) and let the client decide what to do with it.

Can PL/SQL read/write from a database server to another server?

hi,
please advise.
thanks

what i mean is output text file to other servers using pl/sql through utl_file package.No. utl_file reads/writes only on the server where your pl/sql code is running.
But maybe you could map a network drive. Haven't tried that.

How to read .xls file from FTP server t oInternal table

Hi
am using the FTP_SERVER_TO_R3 to read xls file from FTP server to internal table
but the data i get in LT_TEXT is special characters.
CALL FUNCTION 'FTP_SERVER_TO_R3'

handle = hdl
fname = f_name "ProdDataFromCRM.xls.
* CHARACTER_MODE = 'X'

* BLOB_LENGTH =

BLOB = lt_text
* TEXT = lt_text
EXCEPTIONS
TCPIP_ERROR = 1
COMMAND_ERROR = 2
DATA_ERROR = 3
OTHERS = 4
can any one help me out to get the exact data..
Really appreciate your quick response..
Thank You

Hi, if you really retrieve an excel file, you can not see the data in ABAP. You may see them in Excel. For this you may use
CALL METHOD document->open_document_from_table
of the interface i_oi_document_proxy for OLE objects. You can access the data with reference to the interface i_oi_spreadsheet.
Please check [Desktop Office Integration (BC-CI)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCIOFFI/BCCIOFFI.pdf] for details.
But, who knows, perhaps you want "And Now For Something Completely Different".

FM to read XML files from Application server in ECC5.0

Hi All,
We need to pick up an XML file from Application server/FTP server. The requirement is to parse the XML file and process it to create material master. SAP provides standard function modules to read XML files.
Now we need to read the XML file contents of MM01 and upload into SAP Data Base through BAPI
I need to know about the Function modules to read XML files from Application Server and also about the FM's that will update the Date base tables with the data obtained form XML files.

What are the commands available to read a file from application server and

What are the commands available to read a file from application server and store the file into an internal table?

Hi,
To read a file from an Application Server to an Object there is a command in ABAP called <b>READ DATASET</b>. After that file is transported to that object you have to do a loop and put that data in an Internal Table.
This statement exports data from the file specified in dset into the data object dobj. For dobj, variables with elementary data types and flat structures can be specified. In Unicode programs, dobj must be character-type if the file was opened as a text file.
For dset, a character-type data object is expected - that is, an object that contains the platform-specific name of the file. The content is read from the file starting from the current file pointer. After the data transfer, the file pointer is positioned after the section that was read. Using the MAXIMUM LENGTH addition, the number of characters or bytes to be read from the file can be limited. Using ACTUAL LENGTH, the number of characters or bytes actually used can be determined.
In a Unicode program, the file must be opened with an arbitrary access type; otherwise, an exception that cannot be handled will be triggered.
If the file has not yet been opened in anon-Unicode program, it will be implicitly opened as a binary file for read access using the statement
OPEN DATASET dset FOR INPUT IN BINARY MODE.
. If a non-existing file is accessed, an exception that can be handled can be triggered.
Influence of Access Type
Files can be read independently of the access type. Whether data can be read or not depends solely on the position of the file pointer. If the latter is at the end of the file or after the file, no data can be read and sy-subrc will be set to 4.
Influence of the Storage Type
The import function will take place irrespective of the storage type in which the file was opened with the statement OPEN DATASET.
If the file was opened as a text file or as a legacy text file, the data is normally read from the current position of the file pointer to the next end-of-line marking, and the file pointer is positioned after the end-of-line marking. If the data object dobj is too short for the number of read characters, the superfluous characters and bytes are cut off. If it is longer, it will be filled with blanks to the right.
If the file was opened as a binary file or as a legacy-binary file, as much data is read that fits into the data object dobj. If the data object dobj is longer than the number of exported characters, it is filled with hexadecimal 0 on the right.
If the specified storage type makes conversion necessary, this is executed before the assignment to the data object dobj. Afterwards, the read data is placed, byte by byte, into the data object.
System Fields
sy-subrc Meaning
0 Data was read without reaching end of file.
4 Data was read and the end of the file was reached or there was an attempt to read after the end of the file.
Thanks,
Samantak.

Reading XML file from application server and put into internal table-4.6C

Dear All,
Is there any way of reading XML file from application server to SAP? I am using 4.6C. Function module SCMS_STRING_TO_XSTRING function module is not available. Please suggest.
Thanks and regards,
Atanu

Hi Atanu!
Simply use the XSLT transformation 'ID'.
FIELD-SYMBOLS <ls_result> TYPE ANY.
CREATE DATA lref_data TYPE (your_structure).
ASSIGN lref_data->* TO <ls_result>.
CALL TRANSFORMATION id
SOURCE XML xmlstr
RESULT result = <ls_result>.
"xmlstr" contains your XML file. Just read it into it via standard I/O operations. "<ls_result>" will contain your DDIC formatted content.
Best regards
Torsten
