How we write into properties file using get class method

Hi
I want to set some value into properties file using given code
can any one please tell me how i can do this.

               FileOutputStream oOutput= new FileOutputStream("Setting.properties");
               obj.store(oOutput, "");
thanks.

You can't.
If you have properties that change dynamically, you should not be using a properties file that sits in the classpath, you should be using Preferences, or a properties file that sits in some application or possibly even user directory, but not one in the classpath. The proper way to do this, would be to have a properties file in your jar (or otherwise in your classpath) that contains the defaults, and another one outside of the classpath in one of the twwo above mentioned areas, then, you read the default one only if the other doesn't exist, or you read the default one first, then read the other overwriting the values from the defaults.
Don't forget to save the properties again (right after loading if you loaded, or always load, the defaults) after every change.

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
     * @param args [0] = source filename
     *        args [1] = destination filename
    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println ("Syntax: java -cp . Kopy source destination");
            System.exit(1);
        File in = new File(args[0]);
        long fileLength = in.length();
        long t = System.currentTimeMillis();
        FileInputStream fis = new FileInputStream (in);
        FileOutputStream fos = new FileOutputStream (args[1]);
        FileChannel fci = fis.getChannel();
        FileChannel fco = fos.getChannel();
        fco.transferFrom(fci, 0, fileLength);
        fis.close();
        fos.close();
        t = System.currentTimeMillis() - t;
        NumberFormat nf = new DecimalFormat("#,##0.00");
        System.out.print (nf.format(fileLength/1024.0) + "kB copied");
        if (t > 0) {
            System.out.println (" in " + t + "ms: " + nf.format(fileLength / 1.024 / t) + " kB/s");
}

Hey, I couldnot find any xsl usage inside pipeline pair in the links given by you. Do you have any links that gives a sample example.I could not find any links with examples. I will send you a simple config jar demonstrating the use of XSLT resources/transformations.
secondly should MFL doc replicate the name(s)of the nodes of the source xsd:I'm not sure If I understood your question.Can you please explain?

How to write run.bat files

Can anyone tell me how to write run.bat files to run java classes. Currently my run.bat file has the following two lines,
c:\j2sdk1.4.1_02\bin\javac.exe *.java
c:\j2sdk1.4.1_02\bin\java.exe questionnair
But the class is not executed. Thanks in advance.

you'll have to provide more details.
Firstly, which package is the class a part of? and secondly, where on the filesystem is the root of the package?
You might also benifit from placing the c:\j2sdk1.4.1_02\bin\ into the classpath.
On a rainy day, check out the ANT tool, it will take care of all that crapola for you.

How to get sql query data and write into csv file?

I am writing to seek help, in how can I create bat. script which can execute the following logic:
connection to the database
run sql query
create CSV file
output query data, into CSV file
save the CSV file
osql
-S 84.18.111.111
-U adw
-P rem
-i "c:\query.sql"
send ""
sed -e 's/,\s\+/,/g' MCI_04Dec2014.csv > localNoSpaces.csv
-o "c:\MCI_04Dec2014.csv"
This what i have so far, and I am little struggling with the logic after creating CSV file. I am unable to get the above script to work, please advice further, where I may be going wrong.
Can you create if statement logic within window's script, to check for null parameters or data feeds?
Any hints would be most appreciated.

Thank you for your reply.
Apology for posting the code irrelevant to the forum, as I am still novice scripting user.
My goal is to create window's script which can compute the above logic and send the final output file (csv), to FTP folder.
Can this logic be implemented via bat. script, if so, is there a example or tutorial i could follow, in order to achieve my task.
Any help would be much appreciated.

Help to export data into a file

Hi,
I am having more than 200 columns in a table. Client wants to export the data into a file with all 215 columns data. When i write the select * from tablename into a spool file. It is getting the data into a multiple lines however client wants each record into a single line.(right now records are getting into multiple lines). I tried to use to_nclob(columnname1)....to_nclob(column215), this way it is getting a single line for each record but it is taking much time(means in a table we have 10M records and explain plan is showing 3 days to export the file). Could you please help me how we can achieve these type of functionalities.
Thanks in advance

Hardly surprising it's taking ages to export 10 million rows, if you're doing it through SQL*Plus, as that involves transporting all the data over the network to the client, which is then rendering all that data in the display (which can be slow to scroll, depending on the size of the window) etc.
Better to get the database to access the file system directly, using UTL_FILE (though this does mean that the file is produced on the server) and then transfer the resultant file to where it needs to go.
Example of a generic template to use as a starting point...

CREATE OR REPLACE DIRECTORY TEST_DIR AS '\tmp\myfiles'

As myuser:

The procedure allows for the header and data to go to seperate files if required. Just specifying the "header" filename will put the header and data in the one file.
Adapt to output different datatypes and styles are required.

How to write 'into' a PDF-document ?

hi there,
i have a new small project to do with the following problem:
i get a file (text-file) with invoices from an external system.
I want to 'overlay' this file with a form, which is a PDF-document.
the question is: is it possible to write 'into the PDF'-form the contents of the text-file ? if yes, how is it possible ?
regards, Martin

well,
this is not what i need, sorry
i don't want to convert the text-file into a PDF-file.
i have an existing PDF-file (a FORM with all the overlay, like graphics, company-logo, etc....). and i have a text file. and i want to 'merge' the text into
the pdf-file.
regards, Martin

Using UTL_FILE i'm able to read csv file. I'm stuck up in appending some more columns to same csvYou'll struggle to append data to an existing CSV.
You'd be better to read the data from one CSV, and create another CSV using that data, and the extra data you want, and then when finished, delete the original file and rename the new file to the old filename.
You should be able to do that using External Tables to read the source file (easier than using UTL_FILE) and UTL_FILE to write the new file.

How to write data to file Java ME cldc 1.1 midp 2.0?

I newly in java me, please help me.
I make project in NetBeans 7.0.1. and use cldc 1.1 midp 2.0.
I want to write data to the file.
How can I do it?
I try to use FileOutputStream. But it don't exists in java.io
NetBeans shows me only this list of classes and interfaces in java.io:
ByteArrayInputStream, ByteArrayOutputStream, DataInput, DataInputStream, DataOutput, DataOutputStream, InputStream, InputStreamReader, OutputStream, OutputStreamWriter, PrintStream, Reader, Writer.
Why it so short?
And how I can write data to file?
Data can be array of bytes (byte[]) or Object it better.

You must use JSR 75: FileConnection. Please check the following article "Getting Started with the FileConnection APIs":
http://developers.sun.com/mobility/apis/articles/fileconnection/
Be sure to use FileSystemRegistry.listRoots().
And welcome to Java ME development. :)

The Write to Spreadsheet File is not the same as writing to Excel -- for that, you should use the Report Generation Toolkit (and there have been a number of posts here, as well as examples that ship with LabVIEW).
That being said, it is not clear (a) what you are trying to do, and (b) what is (or is not) happening. The image you attached looks OK ...
