Batch File With Some Relative Folders
Jul 17, 2014
Batch file (. BAT) problems with some folders on. I created an application in Java and put the JRE folder within the application, because some users do not have Java installed on your machine and the way I did, my application runs. JAR with the JRE that is contained in my application but I created a BAT file that contains the following command:
start "" jre8 bin javaw-jar app.jar
So I run my program in java through the file. BAT calling JRE that is inside the folder and then this JRE runs the mine. JAR and works great anywhere in windows, worked well on a USB key with this command is within. BAT (start "" jre8 bin javaw-jar app.jar).
BAT in certain folders, eg Program Files and Program Files (x86), I need this code to be able to find any directory, regardless of whether the directory has spaces in the name, symbols, numbers or anything else, because maybe people will put the application folder to another location or rename the folder, and if this happens the program will stop working? And especially do not give problems to run inside the Program Files and Program Files (x86) because the application runs everywhere except in these two folders.

There is no problem in the file creation of sequence.FASTA
ERROR IN: the batch file is not execute, So the I am not able to get the output file for display.
ERROR is : java.io.FileNotFoundException: D:vaibhav_workspace.metadata.pluginsorg.eclipse.wst.server.core mp4wtpwebapps oxin-dataoutputprotein.txt (The system cannot find the file specified)
Technologies Used :JSP,Servlet,Process-builder
I have the following code as :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out=response.getWriter();
String values=request.getParameter("t1");
ServletContext servletContext = request.getSession().getServletContext();
servletContext = request.getSession().getServletContext();
String path="//sequence.FASTA"; /*file is created in getRealPath()*/

I get the following error when I try to run my jar file from a Batch file and CMD manually (The batch file is just set to run the jar and record any output to a text file, and open it after).
Exception in thread "main" java.lang.IllegalArgumentException: input == null!

However running from Netbeans, it works perfectly; JFrame and all. I'm not sure if it's something wrong with my classpath (which I don't think is likely) or something in my code that's affecting it, here's the code:

I can't get Relative paths to work. I have created the class.dat file and I can't get java to recognize it. I am using Eclipse as an IDE. Was wondering if I could get Eclipse to recognize it. I tried with a .txt file as well and couldn't get that to work.
import java.io.*;

All I want to do is load an image into a swing JLabel and display it, but I'm going to have to make a JAR of the program and submit it for grading, so I need to be able to get the path of the image file relative to the JAR (at least I think that's how it works - I've never made a JAR before. Right now I'm just trying to load it from a path relative to my netbeans project). I've tried at least 20 different combinations of paths, file locations within the project, etc., but nothing works.
Anyways, here's the test class I've been using to try to figure this out in its current iteration. Right now the image I want to load is in src/resources and the class is in
src/imagedisplaytest
package imagedisplaytest;
import javax.swing.*;
import java.awt.*;
public class ImageDisplayTest extends JFrame {
private JLabel testLabel;
public ImageDisplayTest()
[Code]...
What's the best way to do this?

I done a small application with Javafx that start an Embedded Jetty. All works fine in Windows also with native package. Instead in Mac it works only before native packaging. Seems that the problem is how relative path are considered.
The tree of the content is this:
myfile.jar
webapp (folder)
libs (folder)
Look at this code:
String webAppDir = "webapp";
File f = new File(webAppDir);
log.debug("Path webapp folder: " + f.getAbsolutePath());
if (!f.exists())
throw new Exception("The folder " + f.getAbsolutePath() + " doesn't exist");
[Code] ....
The problem is that before the packaging in Mac the relative path is that where the main .jar is located an so the code works because the webapp folder is found. Instead after the bundle the path became /Users/MyUser/webapp and of course the folder is not found because it is bundled inside the file.app near the libs folder.

I'm currently making a Breakout clone to learn about different ways of organizing my code and whatnot but I've run into a problem with the positioning of some pieces versus the position of the mouse.
I've created a blue rectangle on the screen that turns white when the mouse hovers over it, BUT it actually only ends up turning white about halfway down and then continues on off the block. I moved the rectangle to 0,0 to see where it draws and it looks like it is drawing to the very top left corner of the window itself but for the mouse coordinates, the top left is just where the black area is and excludes the borders of the window.
Here is the class rendering the rectangle, it extends from a class that in turn extends from the JPanel class:
public class MainMenuState extends MenuState {
JFrame gameFrame;
Graphics2D g;
// PlayButton variables
int playPosX = 0;
int playPosY = 0;
int playWidth = 100;
int playHeight = 50;
[Code] ....
A few other things I tried that I can think off the top of my head: Play around with different layouts (at times this caused the screen to shrink to a small size as well as using pack()), using setSize() setLocation() or setBorder() in the MainMenuState class which had no effect.
Someone on another forum also suggested trying to utilize component.getLocationOnScreen(): I tried two things with the getXOnScreen method, first subtracting with the location of the JPanel which of course gave me the same problem. After that I tried
MOUSE.x = event.getXOnScreen() - gameFrame.getLocationOnScreen().x;
MOUSE.y = event.getYOnScreen() - gameFrame.getLocationOnScreen().y;
but that resulted in some errors (null pointers) and the mouse was just printing out a position of 0,0

When I assign a classpath-relative URL to an ImageView's 'Image' property, SceneBuilder is unable to display the Image in the Preview. It shows the text "Image not found" instead as a placeholder, which makes sense. What I'd like to do is add a classpath entry to SceneBuilder such that it is able to locate and display the Images. Any way to accomplish this (or similar)?

I am copying the xml files from one folder to other folder, in the source folder, i have some files which have some content like "backing File="$IDP_ ROOT/metadata/iPAU-SP-metadata.xml" but while writing to the destination folder.i am replacing the "$IDP_ROOT" with my current working directory. The entire copying of files is for deploying into tomcat server. The copying is done only when server starts for the first time.Problem: If i change the folder name from my root path in my machine after i run the server,the entire process will be stopped because the destination folder files already contains the content which is with existed files names or folder names.
So i want to change it to relative path instead absolute path. What is the best way to do it? Please look at code below:
[ // Getting the current working directory
String currentdir = new File(".").getAbsoluteFile().getParent() + File.separator;
if(currentdir.indexOf("ControlPanel")!=-1){
rootPath=currentdir.substring(0, currentdir.indexOf("ControlPanel"));
}else{
rootPath=currentdir;

I am creating a web application that runs on server X(unix) and it has another unix system mounted on it. I want to generate the file tree structure of this mounted unix file system and show it on to a web application so that users can select a file and move it onto this current unix machine.
I know this sounds stupid and you may want to say why cant we directly copy the file, I am doing a proof of concept and using this as a basis.

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] .....
And then here is the data from the text file that i must extract to use to create product objects.
Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19
These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....

New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.
