package java.io
InputStream.read(): int
Reads the next byte of data from the input stream.
Implementation:
InputStreamReader
An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted.

How to store the contents of a text file directly in to a clob field

Hi All,
Could anyone help me to store the contents of a text file (*.txt,*.xml etc)directly in to a clob field.
Thanks in advance
Jayaram.

One way is to use sqlloader. Three files are used. A control file, an xml data file, and a file with the path of the xml data file. Here's the control file. It reads load.file, which is the file with the path of the xml data file. It names the path ext_path, and inserts the xml into field xml_field.
CONTENTS OF CONTROL FILE:
load DATA
INFILE 'load.file'
APPEND
INTO TABLE xml_table
( ext_path FILLER CHAR(13),
"XML_FIELD" LOBFILE(ext_fname) TERMINATED BY EOF
CONTENTS OF FILE LOAD.FILE:
/tmp/load.dat
The xml is in the file /tmp/load.dat.
null

Hi,
Let us consider you have list of names(Seperated by delimeter) in a text file and you want to display in a table.
1. Create Context Node "Names" and context attribute "Name"
2. Create Table and bind to the above context.
3.Write the following code in the "Init method.
try{
FileReader f =new FileReader("");
BufferedReader r=new BufferedReader(f);
String names=r.readLine();
Vector Names=new Vector();
// Use Tokenizer and store all the names i a vector//
for(int i=0;i<Names.size();i++){
IPrivate<<VieName>>.INameElement ele=wdContext.createNameElement();
ele.set<<Name>>( Names.get(i).toString());
wdContext.NodeName().addElement(ele);

How to check the content in a text file line

hi all,
i had the following problem:
There is a text file with multiple lines of data in it
The data comprises of characters, numbers and symbols
In this file, any line can be commented (till the end) by using symbol ';'(semi-colon)
Now i have to find the number of occurences of a symbol '$' in this data, such that
it should not exist in a commented line
One more limitation is that ';' (semi-colon) could occur at any position in a line, i.e., if this occured in the middle of the line, then all the following data in the line is taken to be as commented one and we have to skip it and move to next line.
Plz do help.

santosh

How to display the contents of a text file on the command line?

I realize I need to utilize classes from the java.io.* package, but I don't know which ones to use exactly. This is what I would like to do in a nutshell:
public static void main(String[] args) throws IOException {
File inputFile = new File( <path to the file>);
// code that reads data from the above file and is able to
// append it to a string object or display it on the command
// line (System.out.println)
}Thanks for your time!

It's pretty easy. Here's a little example that reads a file, stores it in a string, and prints it to the command line.
import java.io.*;
public class OpenFile {
 public static void main(String args[]) {
 try {
 File fileToOpen = new File("something.txt");
 FileReader fileIn = new FileReader(fileToOpen);
 BufferedReader br = new BufferedReader(fileIn);
 String fileContent = new String();
 String line;
 while ((line = br.readLine()) != null) {
 fileContent += line + "\n";
 System.out.println(fileContent);
 br.close();
 catch (IOException e) {
 System.out.println("Exception: " + e);
}Good luck,
Alex

Why don't you try Xerces2?Why don't you tell him to use the javax.xml APIs that are already built in? And that use Xerces2 under the hood? Instead of throwing out a suggestion that might lead to him adding another copy of Xerces into his application?
@OP there are several techniques:
- string replacement as suggested by jschell
- XML parsing to a DOM and then use the DOM API
- XSLT
Which you should use depends on the complexity of your requirement.

I want to read the content of a text file dropped in a watched folder into a string variable

I have a workbench process with 2 variable.
inDoc (DataType=Document/input/required)
outStr (DataType = String/output)
The document being passed to the workflow is a text file with 4 lines of text in it. when the text file is dropped into the watched folder, it will be assigned to the inDoc parameter in the workflow.
My workflow needs to extract the 4 lines of text and write it into a string (outStr).
Id like to use the FileUtilsService.ReadString service but i can't since its input parameter is the file path. When i do, i get the following error...

at com.adobe.livecycle.fileutils.FileUtilsService.readDocument(FileUtilsService.java:363)
which is what i expected...
I've also tried with the Script.executeScript to call some java code but im not too strong in java and in all the examples i find, the file pointer requires a file path.
import java.io.*;
FileInputStream f = new FileInputStream(patExecContext.getProcessDataValue("/process_data/inDoc"));
OR
File f = new File(patExecContext.getProcessDataValue("/process_data/inDoc"));
OR
File f = patExecContext.getProcessDataValue("/process_data/inDoc");
Any clue how to resolve my problem?

Try the following code snippet to read the String content from the file recieved through watched folder endpoint.
com.adobe.idp.Document inputDoc = patExecContext.getProcessDataDocumentValue("/process_data/inDoc");
java.io.InputStream inStream = inputDoc.getInputStream();
byte[] dataBuffer = new byte[inStream.available()];
inStream.read(dataBuffer);
String strData = new String(dataBuffer);
patExecContext.setProcessDataStringValue("/process_data/outStr",strData);
The code is not tested, hence if you find any mistakes, correct and test the functionality.
