Executable Jar File - Will Not Load Data From CSV File
May 5, 2015
I have a small application that I have been working on for several months. It works great. Now when I created an executable .jar file for it, it will not load data from a .csv file. I have tried looking into everything I can think if. I checked file paths, etc. I am using OpenCVS to read the csv. Is there an issue with that when you include it into another .jar file? I am trying to log if there is an error but I don't even get an error. I just doesn't run past that statement...
I am trying to remove a line based on user input. myFile.txt looks like:
Matt Brian John
However when I enter "Brian" (to remove this line), It is deleted on the temp file (myTempFile.txt), but not renamed back to the original file (myFile).
I made a project in eclipse and exported it with libraries into a jar file.
Now I need to obfuscate that jar file so it can't be reverse engineered or anything.
I just need something basic. Just where I put the jar file as input and it will output another jar file that is obfuscated.
I looked at proguard but it looks complex for something like this. I don't want to be spending ages making config files or anything... What I should use?
Embedding an executable .jar file on a webpage. I am not a programmer and we use Blackboard Publish to package our Blackboard sessions into a standalone executable .JAR file which gives the user the full Blackboard experience. We want to embed this file on our webpage, so I did some research and I understand I have to use a Japplet (?). I have tried putting the basic (J)applet code I found on the web (modified of course) onto the webpage (see code below) but I get a 'ClassNotFoundException' error. I don't have the ability to define the files that are in the .JAR created by Blackboard Publish. How I would go about embedding this file? I can look at the files within the .jar with Winzip but there seem to be loads of .class files and I am unclear which one my webpage is trying to find!
I have an executable jar file that I decompile using androchef. I have to use androchef otherwise I get to many errors especially with jd-gui. I need to know how to export the files after I have decompiled them with androchef so that I can edit a file then send to netbeans and rejar.
I'm trying to run a command line executable file using java but there is no output. On the task manager a conhost process opens when the application is run. I've tried
I'am trying to finish my first Java Game with the slick2D library. I had it all working in eclipse but when i was about to make a jar file of it i did realize that i had to use class loader to load my png - SpriteSheets. But now to the problem. My ResourceLoader Class looks like this:
My init-Method in the BasicGame class, where i try to load my png-files looks like this:
public void init(GameContainer arg0) throws SlickException { InputStream inputStream1 = MyResourceLoader.load("images/piratR.png"); sprite1 = new SpriteSheet("",inputStream1,32,32);
InputStream inputStream2 = MyResourceLoader.load("images/monkey.png"); sprite2 = new SpriteSheet("",inputStream2,32,32);
animation1 = new Animation(sprite1,200); animation2 = new Animation(sprite2,250); }
And that works fine for loading the FIRST png-file(eg piratR.png), but whenever i try to load another file it just loads the first one again. So in this case sprite1 and sprite2 looks the same though there are different images.
When i switch the "Load order" and Load sprite2 before sprite1 both animations looks different, so I'm sure that i have two different pictures and its always the one that i load first that will get loaded to all the other SpriteSheets.
I can not load my jar file and it is telling me it can not find the main and I thought I had the right files in the right spots. Do I need the .class of my main file for it to make the jar file. I do not understand If I need to make a .jar out of the main then add all the other files to create the jar.
I have a problem. Depending on one of the request variables, i need to load different properties files. All these property files have same keys, but with different messages. I need to take the user to different sites(though internally, the backend logic remains same...Look and feel of the front end along with messages to be shown change to make the users feel they are being directed to a different site).
I am thinking of loading the properties file from the JSP when the user logs in first time from login page so that these properties are available until the session expires & not read the properties file in Controller.
Okay I am having a problem I wrote some code to transfer a file from my server when requested by the client. The problem is that when the file which is requested is transferred the file cannot be open in its respected file launcher when clicked. The File launcher throws back this msg "My Issue It request the File but after the File is requested and stored on the Client Machine when I Hit the File to be Launch adobe says the file "Adobe could not open the File for it is not supported file type or because the file as been damage"
So i have two pair sets of code for original coded by me. Original code i had first Server
import java.io.*; import java.net.*; public class SimpleFileServer { public final static String FILE_TO_SEND = "c:/Users/Acer/Downloads/COAFlags.pdf"; // you may change this public static void main(String args[]) {
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.
I have a couple .java examples I want to mess with but don't know how to get them into Netbeans so I can work with them. What is the process in loading a .java into Netbeans so I can work with the code and run it in Netbeans?
I'm trying to load a class file into Oracle using loadjava and I get the following error:
ORA-29552: verification warning: java.lang.UnsupportedClassVersionError: helloworld (Unsupported major.minor version 51.0)
Presumably this is related to an inconsistency between the jdk that I used to compile helloworld and the Oracle JVM? Or something like that?
My JAVA_HOME is C:Program Files (x86)Javajre7bin My javac version used to compile the code is javac 1.7.0_15 java -version is "1.7.0_15" When I do a find on java.exe in the oracle installation directory (I'm running 11.2) I get
I am trying to load a CSS file from a mySql DB table (each row represent a customer that use the application, and each one can set his own CSS file).
How can I convert the Stream / String that I loaded from the Clob column to something that I can use here XXXX
scene().getStylesheets().add( XXXX );
I found alot of examples, but they all talking about files from filesystem, or URLs. My CSS file is in the application memory. I want to prevent the option to write my string as a new file and then read it again. I have no problem with loading the CSS file from database, this part is O.K.
I would like to understand how does multipart/form-data works during file upload scenario's, Does it chunks the data from client to server while transferring the files ?
By using FileReader, FileWriter and their constituents, I am creating a file to contain employee information ( name, age, hours, etc. ). The user is to input all of the data on a single line and we were asked to implement StringTokenizer to assign that data to the file. I have never used the StringTokenizer before, but I have a rough idea how it is to function. I used pw.println to test what I have so far, now I would like to let the user build the initial file with the "first employees" of the company, and then view the file, and then go back and append new employee data to that same file. My question is, how can I take the user input as a StringTokenizer and add that to the file?
In the for loop below, I thought I would see if it would work, but it does not. The loop only executes once and does not allow me to enter data.
public class Records { public static void main(String [] args) throws IOException { Scanner input = new Scanner(System.in); FileWriter fw = new FileWriter("dbs3.java"); BufferedWriter bw = new BufferedWriter(fw); PrintWriter pw = new PrintWriter(bw); System.out.println("NEW EMPLOYEE DATA SHEET"); System.out.print("Number of new employees: "); int number = input.nextInt();
I am creating a program where it reads the data inside a file and then places this data into arrays. The file I created has numbers 1-30 in it, file named, testing1.txt .
I am writing a java program which searchs data from a database on a website , my problem is that the url does not works on IE but works fine in other browsers..
