Read request strings from application

HI,
Please help, I need write an app that connects to a URL, and then reads and sends request strings to and fro. What class must I use, and what event is fired when a request is received? This app is not a servlett, but is standalone. Also, I would like to use J2sdk, but if there are other API's, I will use them as well.
Thanks

How to design and implement an application that reads a string from the user and prints it one character per line???

This is so trivial that it barely deserves the words "design" or "application".
You can use java.util.Scanner to get user input from the command line.
You can use String.getChars to convert a String into an array of characters.
You can use a loop to get all the characters individually.
You can use System.out.println to print data on its own line.
Good luck on your homework.

Hi,
You can check the mode in which you are reading the file
from application server that is
Open Dataset in Binary or Text Mode.

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 READ DATASET. 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.

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

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 read a string from file & assign the val to a variable in batch file

Hi,
How to read a string from a file and assign the value to a variable then return the value to the screen in windows batch file?
Any suggestions?
thanks.

Unless this is a homework question then I don't see the purpose of doing this, but....
You should be looking a the supplied package utl_file to get the string out of the file, dbms_output to display the string and then google windows batch/command files calling sqlplus to execute your program.

Hello,
i use Labview 5.1 with WIN NT4.0 SP6a and i programm a fuzzy Logic tool for a exam in Computer Science.
Now i have a problem, and i read something about the GOOP and the EXCEL Toolkit. I download it and try more times to install but i can't link the *.llb in the Function Palette. Is this GOOP and Excel Toolkit only for Labview 6.x ?
I solve it with ActiveX and Excel, but my very big Problem is, i need to read2 string from the Excel table from the same time, and with ActiveX i don't find any method how can i do that.
I don't know how can i read 2 Strings from a Excel table, Can i do it with the Excel Toolkit,if yes how, maybe anyone make it or any helpfiles?
Thanks for your answer in advance ,

I'm pretty sure the excel toolkit is written for 5.1, and don't know why it
would give you problems. Do you have excel installed? I'm not sure what
you mean that you cant link the *.llb in function pallette. Have you tried
opening the llb using '\functions\select a vi' ? As to how to read two
cells at once, you could read a block of cells including both cells (ie:
A5..D10) and then pull the data out of the array.

Function module to read xml files from application server

Hi experts,
I need to read xml files from application server to sap. Is the any siutable function moldule for that?

Hi Cenosure,
Donno about FM which will upload data directly to SAP, I think you have to do some mapping for it so that it will suit the SAP format. Again it depends on your requirement..
Please elaborate more about your requirement.
Please have a look on below FM
TEXT_CONVERT_XML_TO_SAP
Also search on SCN there are many threads on the same topic available.
http://abapreports.blogspot.com/2008/09/upload-xml-file-from-application-server.html
This is the link which will give you the Code
http://www.geocities.com/rmtiwari/Resources/MySolutions/Dev/Codes/Report/Z_RMTIWARI_XML_TO_ABAP_46C.html
Use this XML file to Upload the same, this Program will work for your XML file also,
http://www.geocities.com/rmtiwari/Resources/MySolutions/Dev/Codes/Report/input_xml.xml
See the below thread also
Upload XML to internal table and vice versa in SAP 4.6C
Hope it will solve your problem..

Reading XML File from application server

Hi experts,
My aim is to read a XML file from application server and extract the relevant data from it and process further.
When I am trying to read a XML file from application server it is reading success fully but the problem is that its not reading the last root structure of XML file why is so happening can any body help me?
I am using the following code:
TYPES: BEGIN OF xml_line,
text(256) type x,
END OF xml_line.
DATA: e_file LIKE rlgrap-filename VALUE 'applcatin server path'
OPEN DATASET e_file FOR INPUT IN BINARY MODE.
IF sy-subrc EQ 0.
DO.
    READ DATASET e_file INTO wa_item1-text.
    IF sy-subrc EQ 0.
      APPEND wa_item1 TO gt_item1 .
      CLEAR wa_item1.
    ELSE.
      EXIT.
    ENDIF.
ENDDO.
ENDIF.
CLOSE DATASET e_file.
after this i am passing this internal table to "cl_ixml" class to extract the data
but it returning the itab with required value except the last record.
The stream reading the file it self is i thought in complete thats why it is not converting the all values.
Please help me...
Thanks a ton in advance.

Hi,
1 Copy Report BCCIIXMLT1
2 (you can change the way of filling internal table xml_table if necessary)
3 you don't need the part between
*-- render the DOM back into an output stream/internal table
and
*-- print the whole DOM tree as a list...
Comment it out or simply delete it
4 Rename form print_node to your liking e.g. process_node
5 In your new form you need three extra variables:
data: attribs type ref to IF_IXML_NAMED_NODE_MAP,
      attrib_node type ref to IF_IXML_NODE,
      attrib_value type string.
6 After the lines:
when if_ixml_node=>co_node_element.
string = pNode->get_name( ).
Insert:
attribs = pNode->get_attributes( ).
clear attrib_value.
case string.
when ''. "put your XML tag name here
    attrib_node = attribs->get_named_item(name = '' ). "put your XML attribute name here
    attrib_value = attrib_node->get_value( ).

Is there a way for the end user menu to read a value from a query string?
Or can user/main.jsp be modified to pass the value from the query string to the end user menu?

can you brief ur requirement?

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.
