Create A Jar File That Would Open 3 Other Jar Files
Jan 13, 2015
I was just wondering how would I create a jar file that would open 3 other jar files when I open the jar file with my batch file it and when I type stop in the batch file it will out put the stop command into all 3 of the other jar files.
This is for my Minecraft server so I can launch them all at the same time and inStead of having to enter the commands in all the server batch files I just have to do the command in 1 I know their is things like multi craft to do this but I want the code so I don't have to use multicraft.

I am creating an application in core java where i am using database. I need to create a database configuration file & include it all other files. So, how can i do that ?
Java Code:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:MYDSN","system","tiger"); mh_sh_highlight_all('java');
I cannot do this in an interface since only abstract methods exist there. I tried to create an another class file to extend it but my program is already extending other class i.e. javax.swing.JFrame..How can i implement this ? just by creating the object of that class in main method ?

I have written a program (DOM Parser) that parses data from a XMl File. I would like to create an individual file with the corresponding name for each set of data parsed from the xml document. If the parsed output is Single, Double, Triple, I would like to create an individual xml file (Single.xml, Double.xml, Triple.xml)with those corresponding names. How do I create the xml files and give each file the name of my parsed data output?
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;

I have looked over other people code relating to files that are related to my actual studies in class. My teacher hasn't worked on a lot of file problems so I want to gain some understanding on it.
1.) I have this class with variables declared
import java.io.*;
public class FileDisplay {
private String filename;
FileWriter outputfile;
File Inputfile;
I'm aware that having a private variable would not allow that variable to be accessed outside the code. Vice versa, public variable would do that. The FileWriter and the File Inputfile is something I don't understand, especially have them in classes. What is the purpose of them?
2.)
public class FileDisplay {
private String filename;
FileWriter outputfile;
File Inputfile;
[Code] ....
I have made this code here that opens the output and input file. If I make another method, how would I display the text onto that same file. Hard to clarify for me, but in each method do I just keep creating :
FileWriter outputfile=new Filewriter(filename)

What does this error mean, and also, when I get it, the command line hangs so that I can't do anything else (Is there a way to recover from that?). I'm running Windows 7.

i have an older file I was working on 2 months ago and when i try to open it in eclipse I get a message corruption error. I know this is not possible since I was just working on it a while back, and it's the same program version as what i am currently using..Or would I do a file import instead?

Is there a way we can open a .chm file stored at server through jsp application without downloading the file and saving it to the local machine.
What I googled is : we cannot download .chm files from a web browser and simply click Open. Download the .chm file to your computer first, right-mouse click it in Windows Explorer and select Properties. Then click Unblock.
But I want my users to simply view the file without downloading it.

I am trying to write a java code for a homework problem in my intro java class but im having problems. This is the problem:
Write a program that open the MyFile.txt and read from a file with these criteria.
1)-The program should display the first five lines of the file’s contents only.
2)-If the file contains less than five lines, it should display the file’s entire content. You must check for end of file and less than 6 lines on the loop iterations.
3)- your program should use loop to read the line by line of the file MyFile.txt.
The serperate myfile.txt has this
I can still remember, at the end of that year, we sat for the last time in our circle together. She played us her favorite song, "like a bridge over troubled water" and quietly passed out a gift she had made for each of us.She had made each of us a pottery heart with our name and the date on it on the back each read "I believe in ME".We all cried including her. She told us she would always remember US. We believed she would.
and this is what the code is suppose to look like after you run it : Java33.png
And this is what i have so far : Java22.png
what needs to go next to complete the javascript to show the first 5 lines of the text files?

I have recently taken up some java after a period of time learning batch scripting. the issue I have run into is that my build compiled and ran just
fine when invoking from within the netbeans IDE but after that I 'cleaned and built' the jar and the IDE stored it in the directory that I specified while installing.
I went to that folder, double clicked on my gui and go nothing. So then I opened a command prompt did, "java -jar myapp.jar" and got the following of which has me completely lost:

So I am trying to open a file and store the contents into a two dimensional array. I seem to have no problem using this same basic code to read the file and output it. But when I try to change it so that all the data is stored into the array, it does not work.
Java Code:
public void convertFile()
{
String filePath = ("C:UsersBradDownloadsFB1.csv");
String [][] rowCol = new String [429][6];
try
{
BufferedReader br = new BufferedReader(new FileReader(filePath));
StringTokenizer st = null;
System.out.println("Your file is being converted to an array. This may take several minutes.");

I'm working on a problem where I have to use the FileInputStream to opens a file that contains the name of a user's favorite book and then displays it.
If the file doesn't exist, then I prompt for the book title and write it to the file using FileOutputStream. This is what I have so far but I'm lost because if I put a file that exists in line 8 then it closes, but if I don't and the user puts their favorite book nothing happens. Or, as far as I can tell nothing does.
import java.io.*;
class DisplayBook {
public static void main(String[] args)

-I created the project with the checkbox "Create separate folder for sources and class files."
-I've tried running the program with the "mfq.txt" file in the root directory, the src directory, and the bin directory.
-I've even tried it in all three directories at once!
-I've also refreshed my project after each change in eclipse
-My error is the "FileNotFoundException" error
Here is the line giving me trouble
Scanner file = new Scanner(new File("mfq.txt") );
Where my code is wrong/where I should put my file? :tax:

I'm making a website with articles (like a blog). I have a webpage called admin.html where you insert the data of the article (title, post etc).
Admin.html calls to a servlet and this sends the information to a SQL Database and it stores and my index.jsp calls to database and show the articles.
This works perfect, and a non-programmer can insert new articles. The problem is that I need to create an .html file for every article/post and save it into my server online.
For example if I create "CoolArticle", I need the file "CoolArticle.html" and save it in my hosting.
How I can do it? I never have seen examples online, all were local, so I can't continue.

I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data. Here is the base Product class that must be used to create the objects for the array.
public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;
[Code]...
these continue for about 40-50 entries, they are not seperated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name seperated with spaces, then price after a comma, then quanity after the second comma.....
