hi Jin
im trayin do a UDF enconding, but in dont know how to do that. I Created a User Function.
Imports: com.sap.aii.mapping.api.DynamicConfigurationKey;com.sap.aii.mapping.api.DynamicConfiguration;
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keyF = DynamicConfigurationKey.create( URLFile, "FileName");
DynamicConfigurationKey keyD = DynamicConfigurationKey.create( URLFile, "Directory");
String valueOld = conf.get(keyF);
String valueOldD = conf.get(keyD);
if (valueOld != null) {
    String valueNew = valueOld.replaceAll("Sender.xml",file);
    conf.put(keyF, valueNew);
if (valueOldD != null) {
    String valueNewD = valueOldD.replaceAll("/IN",dir);
    conf.put(keyD, valueNewD);
return name;
URLFile: http://sap.com/xi/XI/System/File.
I dont know if the logic of function is right.
I made a Test in XI and the result was this:
Compilation of dynamic_directory_MM successful Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._dynamic_directory_MM_ method FileCOutput$[http://sap.com/xi/XI/System/File, Sales.xml, c:/, Rodrigo, com.sap.aii.mappingtool.tf3.rt.Context@9159fe] com.sap.aii.utilxi.misc.api.BaseRuntimeException: Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._dynamic_directory_MM_ method FileCOutput$[http://sap.com/xi/XI/System/File, Sales.xml, c:/, Rodrigo, com.sap.aii.mappingtool.tf3.rt.Context@9159fe]

Error in sender file adapter: source directory does not exist

Hi,
The PI system is 7.11
I've created sender file adapter with following details:
Transport Protocol : File System
Source directory: /interfaces/In
I checked in AL11 that this path really exists and it does. (I can even see the .txt file that should be processed.)
But still i get in Communication Channel Monitoring the following error:
"Configured Source directory "/interfaces/In" does not exist.
(i also tried to give the source directory as "interfaces/In" and as "//interfaces/In" but still the same error.
Any suggestions as to what is wrong?

Actually, Need to use forward slash (/) to separate directory names in accordance with the Java specification.
But wanted to try if that works..
Also check directory name , path again as this is case sensitive...

How do i delete Older files from the directory before create a new file?

Hi,
How do i delete older files in a particular directory,
the senorio is count the number of .txt files in a directory and delete the older files if file count is more than 10. (if i add 11th file the very first file has to be deleted)
i have written the code to count the files and delete , but it is deleting all the files instead of older file
public class ExtensionFilter implements FilenameFilter {
private String extension;
public ExtensionFilter( String extension ) {
    this.extension = extension;
public boolean accept(File dir, String name) {
    return (name.endsWith(extension));
public class FileUtils{
public static void main(String args[]) throws Exception {
    FileUtils.deleteFiles("c:/countfile/", ".txt");
public static void deleteFiles( String directory, String extension ) {
    ExtensionFilter filter = new ExtensionFilter(extension);
    File dir = new File(directory);
    String[] list = dir.list(filter);
    File file;
    if (list.length == 0) return;
    for (int i = 0; i < list.length; i++) {
      //file = new File(directory + list);
file = new File(directory, list[i]);
if ((list[i]).length()>=10)
     System.out.print(file + " deleted : " + file.delete());
Thanks,
Jamin Rosina

What your code is doing now, is deleting all filenames that are longer than 10 characters.
Your problem lies in the line:
if ((list).length()>=10)

How do I delete a file from a directory

The f.delete() is after I copy the file to an archive directory.

Java Program to copy file from one directory to another failing

Hello All,
Oracle Applications 12.1.3
RDBMS: 11.2.0.30
SQL*Plus: 10.1.0.5.0
Java beginner here so help is much appreciated. I'm have some java code that I'm using to copy a file from one directory to another in an Oracle Applications Server. I notice that when moving to a new instnace I started to get file not found errors. I think it's because of the directory. My question is, does the directory in which I trying to pick up the file have to be a DBA_DIRECTORY, or a UTL_FILE directory in order for the java to find the file and move it?
Here is my code...
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "COPY_FILE_JVS" AS
import java.io.*;
public class COPY_FILE_JVC{

    File source = new File(SourceFile);
    File dest = new File(DestDir);
    File cpDestFile = null;
    try {
      if (dest.isDirectory()) {
          if(source.isFile()) {
            System.out.println("File name = " + source.getName());
            System.out.println("File name dest = " + dest.getPath() );
            System.out.println("File name cpDestFile = " + dest.getPath() + File.separator + source.getName());
            cpDestFile = new File(dest.getPath() + File.separator + source.getName());
          else {
            System.out.println("Directory or File Not Found");
            return;
      BufferedInputStream br = new BufferedInputStream (new FileInputStream (source));
      BufferedOutputStream bw = new BufferedOutputStream (new FileOutputStream (cpDestFile));
      int read = 0;
      while((read = br.read()) != -1) {
        //System.out.println((char)read);
        bw.write(read);
      br.close();
      bw.close();
    catch (FileNotFoundException e) {
    e.printStackTrace();
    catch (IOException e) {
    e.printStackTrace();

I get these messages when calling the java from SQL Plus as follows...
serveroutput on size 100000;
dbms_java.set_output(1000000);

PL/SQL procedure successfully completed.
Directory or File Not Found
PL/SQL procedure successfully completed.
If I change the directory from /home/my_user/ to any directory that is defined in DBA_DIRECTORIES or is a UTL_FILE directory to program works. Is it perhaps because the java is in a PL/SQL package as seen below? The PL/SQL program runs as the APPS user and I have issued the following the command grant JAVASYSPRIV to APPS.
Here is the PL/SQL Package....

How to open and read many files from a directory and store contents in 2D array?

I want to make a VI that opens and reads the data from various files contained in a directory (200 files each with 2 columns) and store these in a single 2D array. For file number 1 I want to store the data from both columns in the 2D array, but for files 2 to 200 I only want to store the second column of each file. Can someone please help?

Hi Nadav,
Thanks for your help. I have followed your instructions but i cannot get it to work. I used the LIST DIRECTORY to list the files in the directory - that works. However, how do I read each of the 200 files using READ FROM SPREADSHEET FILE without me having to manually select each of the 200 files? So, if I use LIST DIRECTORY to list all 200 files in an array, how do I get each of these to open and store the data in a 2D array? Here is what I have done (File called read_files.VI) Could you please help me? Thank you very much in advance.

Open file from a directory that is not web accessible?

Subject says it all really, I'd like users to be able to download files from a directory that is otherwise not accessible by the browser. There is a way to do this is PHP, the readfile() function. Is there something equivalent in Java?
Thanks!

You can do that with a Servlet and a shot of java.io API.
Here's an example: [http://balusc.blogspot.com/2007/07/fileservlet.html].

Script to open all PST files in a directory and open with Outlook.

Hi! I am looking for a script that opens all PST files in a directory, opens it in outlook, and writes to a log to see if it completed correctly. I'm new to VBscript and just want to see how the script would be written.
Thank you!!

Thank you for all the input! JRV, I went through the repository and couldn't find anything about importing into Outlook. I will use it for future references and I appreciate you directing me there.
Grant, I need to be able to locate all PST files within a directory, not point it to a specific pst. I also need it written to a log file. Here is what I have...Don't laugh, I'm very new...
const ForAppending = 8
set objTextFile = objFSO.OpenTextFile ("C:\Users\jimmy.nguyen\Desktop\Lucky.txt", ForAppending, True)
set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
strCommand = "C:\Program Files (x86)\Microsoft Office\Office12\outlook.exe"
Set objExecObject = objShell.Exec(strCommand)
wscript.sleep 4000
Set myOlApp = CreateObject("Outlook.Application")
Set myNS = myolapp.GetNamespace("MAPI")
myNS.AddStore "objfile.name"
Sub ShowSubFolders(fFolder)
Set objFolder = objFSO.GetFolder(fFolder.Path)
Set colFiles = objFolder.Files
For Each objFile in colFiles
If UCase(objFSO.GetExtensionName(objFile.name)) = "pst" Then
objFile.Name
End If
Next
For Each Subfolder in fFolder.SubFolders
ShowSubFolders(Subfolder)
Next
End Sub
strResults = ShowSubFolders(fFolder)
objTextFile.WriteLine(strResults)
objTextFile.Close

How do i move a file from one directory to another?

Can anyone help me in moving a file from one directory to another?
The following code just does not work!!
File source_file = new File(source_file);
if(source_file.exists())
File dest_file = new File(destination_file);
if(!dest_file.exists())
boolean moved = source_file.renameTo(dest_file);
System.out.println("moved.."+moved);
The varirable moved is always false.
Can anyone tell me whts wrong in this code?

The problem in your code is you used file object as argument when you create a new File. I changed a little bit codes and it should be fine now.
String source_file1="test111.txt";
String destination_file1="test222.txt";
try{
     File source_file = new File(source_file1);
     if(source_file.exists())
          File dest_file = new File(destination_file1);
          if(!dest_file.exists())
               boolean moved = source_file.renameTo(dest_file);
               System.out.println("moved.."+moved);
catch(Exception e){
           e.printStackTrace();
}

How to get all files in one directory

Hi there,
is there any way to get all the files in one directory?
e.g. a method
File[] getAllFiles(String directory){
Thank you

Just out of interest, which part of the File API was confusing?
http://java.sun.com/j2se/1.5.0/docs/api/index.html
If you look down the left-hand side, you'll see a frame listing "All File". If you select "File" from that list, it opens up the API in the right-hand frame. Quite near the top you'll find "listFiles".
I only ask as this (and other questions easily answered by looking at the API) are frequently asked. Did you overlook it when you read the API or did you just not read it?
I really want to know. I think there is scope to cater for that behaviour within this site. A nice API finder would be good; something more intelligent than the search function (which people use less frequently even than the API docs).

How can I get a file to copy all of the files in a directory except itself and the source of the copy function will be the directory the final program is in?

How can I get a file to copy all of the files in a directory except itself and the source of the copy function will be the directory the final program is in? This application must be in Lab View 8.

you mean something like this (see below)?
Now you may have to implement code to check if the destination folder exists and to create it, etc. But if you use the Front Panel Control to select the destination folder, it should be okay.
Not the best implementation, mind you but you'll get the idea..

How can I create a array with all files from a directory

How can I create a array of files or varchar with all files from a directory?

I thought the example could be improved upon. I've posted a solution on my blog that doesn't require writing the directory list to a table. It simply returns it as a nested table of files as a SQL datatype. You can find it here:

How can i traverse between files in a directory

how can i traverse between files in a directory. I ahve seen in the site that isFile can be used to switch from one file to other but i didn't found such method. I am working in Eclipse. I would be thankful if u send me the solution.I mean the way to traverse

listFiles() returns all the files in a directory. You can check if it is a file and read it. Read the API docs.
If you have specific problem with your code, post the code and the problem description.

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap?

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).
import java.io.*;
public class CacheData {
public static void main(String[] args) throws IOException {
String target_dir = "C:\\Files";
String output = "C:\\Files\output.txt";
File dir = new File(target_dir);
File[] files = dir.listFiles();
// open the Printwriter before your loop
PrintWriter outputStream = new PrintWriter(output);
for (File textfiles : files) {
if (textfiles.isFile() && textfiles.getName().endsWith(".txt")) {
BufferedReader inputStream = null;
// close the outputstream after the loop
outputStream.close();
try {
inputStream = new BufferedReader(new FileReader(textfiles));
String line;
while ((line = inputStream.readLine()) != null) {
System.out.println(line);
// Write Content
outputStream.println(line);
} finally {
if (inputStream != null) {
inputStream.close();

I don't understand your question.
If you don't know how to use TreeMap why do you think a TreeMap is the correct solution for what you want to do?
If you are just asking how to use TreeMap then there are PLENTY of tutorials on the internet and the Java API provides the methods that area available.
TreeMap (Java Platform SE 7 )
Are you sure you want a map and not a tree instead?
