File name to be generated from outbound text file data
Hi Experts,
I am collecting IDOCs and generating IDOC-XML(for IDOCS) file and sending it to PI 7.0 using sender file adapter.
This is File to File scenario.
IDOC-XML file picked by sender file adapter gets transformed using XSL mapping in to .dat(text) file.
Sample Output of .dat file (target file)
STR SE 2008-10-3011:13:00$SEQ
EIH21148862 D2008102820081127SEK000000894800000000894800000000000000 0000XYZ co Ltd KL25533781 2114886209 335592 2508867
EIL21148862 0000000000000000100000000000020081021 335592 20081010KILLL899 Operating System
Now I want output file name to be: ABC_DEF_cc_yyyymmdd_segno.dat
ABC_DEF is constant
cc - means country code, in this case it should be "SE", which is marked in bold immediately after STR.
yyyymmdd - date format
segno - which means no of records like number of lines in text file, (say three records: STR, EIH, EIL)
Please feel free for any clarifications required.
I hope I am able to explain scenario.
I would really appreciate if you can help me with your valuable inouts.
Thanks,
Divyesh
hi,
just put one more mapping as the last mapping in your interface mapping
it can be abap or java mapping
then as per this blog fill out Filename attribute which will set the file name
/people/william.li/blog/2006/04/18/dynamic-configuration-of-some-communication-channel-parameters-using-message-mapping
you can parse the whole IDOC structure in tthose mappings to get all the data you need for the filename
this is the easiest way I'd say

Trying to Scan in a List of Names Using a Delimiter from a Text File
Hello everyone,
I tried posting this question onto [Codecall Forums|http://forum.codecall.net/java-help/16064-trying-scan-list-names-using-delimiter-text-file.html] for an answer, but nobody really helped to solve this problem, so I'm reposting it here.
I'm trying to solve this problem on the Euler Project for practice. For the first part of the problem, I am supposed to scan in names in the following format: "name1","name2","name3". To solve this, I wrote the following code:
import java.io.*;
import java.util.*;
public class AlphabeticalSort
public static void main(String args[]) throws IOException
//import the file
Scanner input = new Scanner(new File("names.txt"));
input.useDelimiter("[\",]");
System.out.println(input.delimiter());
//scan it for the length of the array
int n = 0;
while (input.hasNext())
input.next();
n++;
System.out.println(n);
//import the names into the array
Scanner input2 = new Scanner(new File("names.txt"));
input2.useDelimiter("[\",]");
String[] names = new String[n];
for (int i=0; i<n; i++)
names[i] = input2.next();
System.out.println(names);
}However, when I tested this with a file containing "BOB","STEVE","MARK", n equaled 7 and my output was the names each separated by two empty lines. There are other methods I can use to solve this problem, but I would really like to know why my delimiters are not working so I can use them in the future.
Thanks,
helixed

I believe "[\",]+"{code} will get you the results you need.

How to copy a files name and spotlight comments to a text file for an entire folder
I have movie covers saved as a jpeg for every movie my family and I own. There is about 700 and they each have a comment of the main actors, release dates, and descriptions. This makes it easy to find what to watch. I want my parents to have all of this info but they have a windows laptop so the comments don't transfer with the file and can't be searched like you can on a mac. Is there an applescript, automator, program I can download, or program code supported in xcode that will do at least one of the following things?
1)Take the name of the picture file and spotlight comment, copy and paste it into a text document like word that looks like this...
File Name1- Spotlight Comment for file 1
File Name 2- Spotlight Comment for file 2
. for all 700 files in a folder
2) It would be equally helpful if there was something that would take the name of the picture file and spotlight comment, copy and paste it to a movie file's comments with the same name but obviously has different extention. For an example
In a Pictures folder
Name: Dark Knight, The.jpeg Comment: (2008) Genre: Action... <- copy comment
In a Movie Folder
Name: Dark Knight, The.m4v Comment: <- paste
and do this for all 700 files
3) Is there a free photo program that works on mac and windows that I can put all my movie pictures in and have a description like I did with the comments? It would also need a place that to search the description for keywords. So Basically an itunes for pictures that works on both mac and windows. If so I still need a way to get the spotlight comments to the description.
4) I feel like this would make things more difficult, but if not I can put all of the .m4v files in itunes so instead of pasting all the comments back into a file in finder paste them in a description in itunes
5) At the very least a code that I can run one by one for every file that will paste the comments into the same document
Note: When I say spotlight comments I mean the comment box that is available when you click on get info of a file. The pictures are in the pictures section of finder in a folder called Movie Pictures. The movie files are on an external hard-drive in a file called Movies. Also I am slightly familiar with applescript and automater in that I have used both to create keyboard shortcuts and simple voice commands. I have programmed in c++ and C too. So If you give me a code for applescript I do know what to do with it.
Thanks to anyone who takes the time to read all of this and extra thanks to anyone who tries to help.Clendenen02 wrote:

This Bash script will do it.
Edit "PicDir" and "MovDir" to the location of your Folders
(Note: The comment is written to the m4v file using xattr, so the Spotlight comment field appears blank in Finder, but the comment metadata is still indexed by Spotlight (If you add a Spotlight comment from Finder, it is stored both as an extended attribute and in a .DS_Store file)
#!/bin/bash
PicDir=$HOME/Desktop/Pictures
MovDir=$HOME/Desktop/Movies
for f in $PicDir/*
do
if [ ! -d "$f" -a "${f##*.}" == "jpeg" ]; then
comment=$(mdls -raw -name kMDItemFinderComment "$f")
if [[ $comment != "(null)" ]]; then
picname=${f##*/}
movname=${picname%.*}.m4v
if [ -e "$MovDir"/$movname ]; then
xattr -w com.apple.metadata:kMDItemFinderComment "\"$comment\"" "$MovDir"/$movname
fi
fi
fi

Reading data from a text file into PAS - Dimension member names truncated
Hi,
I created a procedure to dump variables and data into a text file to load into another model. I used a semicolon as a field seperator.
The data, measures and dimension members are dumped properly into a text file and no dimension member names are truncated .
However when I read the data into a measure, and I issue a peek command, dimension meber names are read in truncated
and remain full names in the text file. Any reason for this? What do I need to do to prevent this from happening?
THanks.
LungileHi Lungile,
The problem that you're likely having is that you haven't created a file description for the file from which you're reading. When loading data into Application Server from a text file, you would normally go through three steps:
1. Enter the ACCESS EXTERNAL subsystem
2. Specify the name of the file to be read
3. Specify the format of the file field names, types, widths, and positions.
If you go into the Application Server help, select "Application Server Help", then "Application Server at the command level", then "Variables and reading in data", and then "Reading an external file", you will have the process of the steps you need to follow outlined for you, including links to the help topic for each command you need to issue.
So what I think you need to do is use the DESCRIPTION command to specify the names of your fields, their type, and also their width, in order to ensure no truncation of data on the load.
The same DESCRIPTION statement is required if you want to use your text file as the source of a dimension.
Hope this helps,

Ability to create a collection from a text file containing the names of the pictures
1 thing that would be very good is the ability to create a collection / quick collection from a text file that contains the names of the picture we want in that collection...
The reason for that is when i receive an order from a customer typicaly 100-200 different pictures (i'm a wedding photographer), i ask my customer to send me an excel spread sheet with all the name or number of the picture thay want with size & quantity...
I would like to be able to use that file as an input for a batch job that would add all those files to a collection "customer order" instaid od adding them 1 by 1... it would save me lots of time and would prevent some errors in the order...
I am currently able to do that with the help of a small utility (Useful File Utility) is the name... with the other RAW converter i use... BibbleWell, it is workflow software, true, but it's really focussed on image development. What you're proposing would necessarily make the primary focus be on the business angle, I suspect.
If you're talking about tools to help customers sit down and pick what they want for manual processing later, that's one thing - but going the rest of the distance to order processing and fulfillment would be out of scope, at least in my view. The reason is that there is just so much room for potential variation in how this gets conducted that I can't see how Adobe could possibly satisfy every pro with one implementation. Even just dealing with all of the possible payment vendors is a hugely problematic area.
I agree with Don; a third-party plugin via the upcoming SDK might be a distinct possibility, particularly if it were for a "plus services" solution in which the plugin were designed to work with a specific fulfillment vendor. THAT could work quite nicely, and the plugin might even be free (in return for giving the vendor your business, of course).
In other words, it's not that I see it as a bad idea, it's just that I don't think it belongs in the "core" of LR. This is something that is best dealt with using the SDK so that differences in processes can be allowed for. -
How to save input from a text file in to array
I got this assignment, and almost have no clue, and my teacher doesn't even teaches us anything
This is what i am suppose to do
5. The program must store the following data about each student in this Talent Show:
* The student's name (store as a String)
* The student's average time score [only for the events they competed in] (store as a Double)
Note: Some of the data comes directly from the text file, and some of the data must be calculated from the data that is read from the file.
6. The program must search through all of the student's scores to find the student who has the minumum average time of all students.
7. You must calculate how many events each student played. Zero values are not counted.
8. You must then generate a report on the screen that prints out
* the total number of students in the competition,
* the winning student's ...
o name
o times
o average time (rounded to one decimal places)
Sample output
btw this is the data file

}My question, how do i save the data in to an array, and how do i seperatly save names in to different array, and their scores in to different arrays
bte he said you can use scanner class
Thanks

How to input data into an arraylist from a text file?
I am trying to take data from a text file and put that data into an arraylist. First here is the text file:
[item1, 10, 125.0, item2, 10, 12.0, item3, 20, 158.0]
3
4530.0
[item5, 65, 555.5, item4, 29, 689.0]
2
56088.5
[item7, 84, 34.5, item6, 103, 0.5, item8, 85, 1.36]
3
3065.1The text between the [ ] is the output from my arraylists. I have three arraylists. The first [ ] belongs to arraylist A, the second to arraylist B, and the third to arraylist C. The format of the arraylists is this:
<item name>,<# in stock>,<value of one item>
The first number below the arraylists in the text file represents the number of items in the list. The second number below the arraylists represents the total value of the items in the arraylists.
Here is the class file I have (yes, it does everything):

String line4 = null;
String line5 = null;
String line6 = null;
//Get the item count and total value for each warehouse.
while(inDetails.readLine() != null)
line1 = inDetails.readLine();
line2 = inDetails.readLine();
line3 = inDetails.readLine();
line4 = inDetails.readLine();
line5 = inDetails.readLine();
line6 = inDetails.readLine();

Reading one line from a text file into an array
i want to read one line from a text file into an array, and then the next line into a different array. both arays are type string...i have this:
public static void readAndProcessData(FileInputStream stream){
InputStreamReader iStrReader = new InputStreamReader (stream);
BufferedReader reader = new BufferedReader (iStrReader);
String line = "";
try{
int i = 0;
while (line != null){
names[i] = reader.readLine();
score[i] = reader.readLine();
line = reader.readLine();
i++;
}catch (IOException e){
System.out.println("Error in file access");
this section calls it:
try{
FileInputStream stream = new FileInputStream("ISU.txt");
HighScore.readAndProcessData(stream);
stream.close();
names = HighScore.getNames();
scores = HighScore.getScores();
}catch(IOException e){
System.out.println("Error in accessing file." + e.toString());
it gives me an array index out of bounds erroroh wait I see it when I looked at the original quote.
They array you made called names or the other one is prob too small for the amount of names that you have in the file. Hence as I increases it eventually goes out of bounds of the array so you should probably resize the array if that happens. -
Filling an object ArrayList from a text file
Hi all,
I am developing a project (for university) which has a class named "SupplierAgent", which is required to keep database of custom objects of type "InventoryItem". Basically these consist of a String (for the name of the item), an int representing the quantity on hand, and an int representing the unit price (in cents). I wish to have this inventory loaded from a text file rather than a binary file - that way the user can add new items to the file before loading the agent.
I have included the code below, which works provided the file is rigidly structured. The main problem is the user having to type the path to the file: I cannot guarantee the user will have the file in any folder, and so the user is required to type in the absolute path. Is there any way to make this less annoying? Or is there a better way of loading a preset inventory while allowing the user to edit that inventory at will?
I have included the current code below. it's not exactly in accordance with coding standards, because we are using the JADE agent architecture (hence why the method is called "action") rather than something more informative.
I should also mention that it uses a command line interface. The "io" class basically includes a scanner and the System.out.println method. Its "yesOrNo()" method is for convenience: it asks the user a question and allows them to select y or n.
public void action() {
boolean loadFromFile = io.yesOrNo("Would you like to load the inventory from a file?");
if(loadFromFile) {
BufferedReader br = null;
boolean fileFound = false;
while(!fileFound) {
io.output("Please enter the absolute path to the file, including filename extension: ");
inventoryFile = io.input();
try {
FileReader fr = new FileReader(inventoryFile);
br = new BufferedReader(fr);
fileFound = true;
catch (FileNotFoundException e) {
io.output("File not found. ");
String fileLine = null;
int lineNumber = 1;
InventoryItem item = null;
try {
while((fileLine = br.readLine()) != null) {
switch((lineNumber % 4)) {
case 1: item = new InventoryItem();
item.setName(fileLine); break;
case 2: item.setQuantity(Integer.parseInt(fileLine));
case 3: item.setPrice(Integer.parseInt(fileLine));
case 0: inventory.add(item);
io.output("Inventory loaded successfully\n");
catch(Exception e) {
io.output("Error at line " + lineNumber + " of inventory file\n");
io.output("Unable to fill inventory. Please ensure file is structured correctly\n");
io.output("See readme for explanation of file structure requirements\n");
myAgent.doDelete();

}Some tips:
1) If you are adding or deleting stuff from a text file you need to write a new, modified file and then, optionally, do something like:
rename the old file to whatever.bak or the like.
rename the new file to the old.
2) Don't depend on System.out so much on a GUI application. For example if you get an exception use javax.swing.JOptionPane to display an alert (and show the message from the exception). You can write the stack trace to System.out if you want.
3) Don't muck about with calculating bounds for screen objects, let a layout manager sort it out. I like BoxLayoutManager for most things like this.
4) For bonus points do your IO in a separate Thread. Generally you don't want anything happening in an actionPerformed method which significantly delays it's return. The method should launch a new Thread to do the job, and disable the button until the Thread finishes. -
Retrieve data from a text file and insert in table
hi,
i am writing an application which when executes would creates a user table and populates it with the data i.e. username and passwords taking it from a text file.

Read data from a text file, one line at a time.
I need to read data from a text file, and display each line in a String Indicator on Front Panel. It displays each line, but I get Error 4, End Of Line, unless I enter an extra line of data in the file that I don't need. I tried Read From Text File.vi, made by Nat Instr, and it gave the same error.
The Read from Text File.vi reads data from a text file line by line until the user stops the VI manually with the Stop button on the front panel, or until an error (such as "Error 4, End of file") occurs. If an error occurs, the Simple Error Handler.vi pops up a dialog that tells you which error occurred.
The Read from Text File.vi uses a while loop, but if you knew how many lines you wanted to read, you could replace the while loop with a for loop set to read that many lines from the file.
If you need something more dynamic because the number of lines in your files vary, then you could change the code of the Read from Text File.vi to the expect "Error 4, End of file" and handle it appropriately. This would require unbundling the error cluster that comes fro
m the Read File function with the Unbundle By Name function, so that you can expose the individual error "status" and error "code" values stored in the cluster. If the value of the error "code" is 4, then you can change the error "status" from true to false, and you can rebundle the cluster with the Bundle by Name function. Setting the error "status" to false instructs the Simple Error Handler to ignore the error. Otherwise, pass the original error cluster to the Simple Error Handler.vi, so that you can see what the error is.
Of course, if you're not interested in what the errors are, you could just remove the Simple Error Handler.vi, but then you wouldn't see any error messages.
Best of Luck,

How can I use Automator to extract specific Data from a text file?
I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:
Link Time =
DD/MMM/YYYY
Random
Text
161 179
bytes of CODE memory (+ 68 range fill )
16 789
bytes of DATA memory (+ 59 absolute )
1 875
bytes of XDATA memory (+ 1 855 absolute )
90 783
bytes of FARCODE memory
What I would like to have as a final file:
EXCEL COLUMN1
Column 2
Column3
Column4
Column5
Column6
MM/DD/YYYY
filename1
161179
16789
1875
90783
MM/DD/YYYY
filename2
xxxxxx
xxxxx
xxxx
xxxxx
MM/DD/YYYY
filename3
xxxxxx
xxxxx
xxxx
xxxxx
Is this possible? I can't imagine having to go through each and every file one by one. Please help!!!Hello
You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);
my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
local $/ = qq(\\n);
# CSV spec
# - record separator is CRLF
# - field separator is comma
# - every field is quoted
# - text encoding is UTF-8
local $\\ = qq(\\015\\012); # CRLF
local $, = qq(,); # COMMA
# print column header row
my @dd = ('column 1', 'column 2', 'column 3', 'column 4', 'column 5', 'column 6');
print map { s/\"/\"\"/og; qq(\").$_.qq(\"); } @dd;
# print data row per each file
while (@ff) {
my $f = shift @ff; # file path

warn qq(Failed to open $f: $!);

Error while loading data from a text file to a datastore
Hi all,
i am a starter in ODI. I am trying to load data from a text file into a datastore. I have put the file on a unix server whose location is defined in the topology manager. when i am trying to "view data" it is giving me error file does not exist at <location where i have put the file>. Please help meHi,
1. If your files are on a remote File System, you will need to copy one of your files to the machine ODI Designer is running on to allow ODI to retrieve the metadata information of the file.
2. In Topology create a Physical Schema, the directory you enter for Data and Work Schema should point at this local file.
3. Then define the File Datastore in ODI Designer. Enter a name, browse and select the file and fill in each filed of the Files tab.
* If its a Fixed file, click on the grid icon on the Columns tab to enter the columns and have Automatic Adjustment checked.
* If its a Delimited file, use the Reverse button on the Columns tab to reverse the columns.
* Right click on the File Datastore select View Data, if you can view data, that means the File Datastore has been defined correctly.
* If not, check each tab of the File Datastore to make sure everything is defined correctly and retry.
4. Once View Data is successful, you now change the directories (Data and Work Schema in Topology) to point at the remote File System. These directories must be accessible to the ODI Agent that will be used to run the transformations. The directory can be an absolute path (m:/public/data/files) or relative to the ODI Agent startup directory (../demo/files). It is strongly advised to use a UNC (independent from the execution location) for the path. When running the transformations with "no agent", the directory is relative to the directory where Oracle Data Integrator has been installed.
You need to have a agent process running at the system where your source file resides .
Then while running the odi interface choose that agent .
Thanks,
