I am working on a card game and for lack of better terms, have royally screwed up my files. I do still have an executable jar that I would like to go back to if possible and try to redo what I messed up. What I was able to do was to use WinRAR and get ?encrypted? class files. Something that is obviously not editable. How can I go about converting these back to editable java files, if possible?
View RepliesI am trying to uses classes from a non executable jar called noexec.jar in an executable jar called exec.jar. With no defined manifest in the nonexec jar and a manifest in the exec jar. The folder structure where the jars are held look like so.
ROOT
/lib
|
---nonexec.jar
---exec.jar
With the class path defined in the manifest for the executable jar as Class-Path: nonexec.jar . However every time I run java -jar exec.jar, I get Exception in thread "main" java.lang.NoClassDefFoundError: What even though I am including nonexec in my class path why the classes contained within the jar are not being found?
This is the manifest file
Manifest-Version: 1.0
Class-Path: nonexec.jar .
Main-Class: start
example input (#federer #great #game )->
output : [federer] [great][game], [federer, game],[federer,great], [game,great], [federer, game,great]
Okay So I am creating an application but I'm not sure how to get certain parts of the string. I have read In a file as such:
*tp*|21394398437984|163600
*2*|AAA|1234567894561236|STOP|20140527|Success||Automated|DSPRN1234567
*2*|AAA|1234567894561237|STOP|20140527|Success||Automated|DPSRN1234568
*3*|2
I need to read the lines beggining with *2* so I done:
s = new Scanner(new BufferedReader(new FileReader("example.dat")));
while (s.hasNext()) {
String str1 = s.nextLine ();
if(str1.startsWith("*2*")){
System.out.print(str1);
}
}
So this will read the whole line I'm fine with that, Now my issue is I need to extract the 2nd line beggining with numbers the 4th with numbers the 5th with success and the 7th(DPSRN). I was thinking about using a String dilemeter with | how to extract them once i've used the dilemeter.
Suppose i have a string S="a.png,b.png,c.xlsx";
I need to extract only c.xlsx, how i will do these in java
I have these sample strings in a text file : goldfish, fish, dish, filter and i need to extract them out with letters : "is" and need to print them out in another text file. Currently I am able to read the contents of the file but I am not able to print the same it in the new file.
public class Demo {
public static void main(String[] args) {
String filename = "a.txt";
try {
[code]....
I want to extract a specific String from HTML, specifically, I want to extract a String from in between <...>
So far, I've got this
package main;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class HTMLGrabber {
static String allOneString = "";
[code]....
The problem I have is when I change the last parameter in this line:
System.out.println("And the Keywords are:
" +allOneString.substring(allOneString.lastIndexOf("meta name="keywords" content=") + 30, allOneString.indexOf("Fictional History">")+17));
to
System.out.println("And the Keywords are:
" +allOneString.substring(allOneString.lastIndexOf("meta name="keywords" content=") + 30, allOneString.indexOf("">")));
i.e. the generic alternative, I get this error message:
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -366
at java.lang.String.substring(Unknown Source)
at main.HTMLGrabber.main(HTMLGrabber.java:45)
Is there a better and simple way to extract a substring?
I am trying to do is extract numbers that are in word format in a long String, i.e. a song, and return each of their numerical values, in order to add them all up. So I'd like to calculate the sum of all of the numbers in the text. This has to work for any piece of text and for all numbers up to a trillion.
So I broke the string down into tokens and stored them in a String []. And I divided up the possible numbers in word format into:
LARGEST: thousand, million, billion, trillion
HUNDRED: hundred
TENS: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
UNITS: one, two, three, four, five, six, seven, eight, nine
SPECIALS: ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
I believe that these are the only words that it will need to recognize. I began reading the tokenized string from right to left and then when I came across a unit, special or tens as the first number I hit, I would then set it's numerical value and check if the word before was also a number and whether to add or multiply etc. i.e. First number hit is a two, if the number before is sixty, then I would just add it to sixty and check the word before that and so on.
However, when implementing it, it seems like an extremely long way around it. How I could implement this in a swifter manner? An example of it working would be:
"Nine Million rockets turned Three times and met Twenty Two Aliens", it would extract, Twenty Two as 2, then 20 = 22, then extract Three as 3, and then Nine Million as 1,000,000 x 9 = 9,000,000
9,000,000 + 22 + 3 = 9,000,025
I've been working quite a bit with a login system the past couple of months and I now have a version that I would like to try "for real" by extracting it as a runnable .jar or .exe file. I've looked at a couple of guides that told me how to do this properly, but even after following every step precisely it didn't work.
One of the guides I tried: 3 Ways to Create an Executable File from Eclipse - wikiHow
Double clicking the file or selecting it and pressing enter does nothing, the computer loads for a second and then nothing happens. I don't receive any visible errors when extracting the program, either.
However, when running the file from the command prompt I do receive an odd error:

I must say I don't quite understand the error, it seems to be unable to load an image which is odd considering the program works fine without any errors at all in Eclipse.

View Replies View RelatedSo let's say i have an executable jar and inside that jar is a bunch of files. How do I access files within my jar?
Assuming like, a main class is currently running and that is what's inside the manifest file as the main class inside that executable jar..
I am new to JAVA. I need to execute a program, based on the OS. If I am on Mac, the program is a .x and if It is on Windows the program is .exe. The program also requires a line of commands attached to it (i.e. relap5.(x) or (exe) -i inputFile -o outputFile -r restartFile -s stripFile
Here is my coding
String in = " -i ", tfIntdta.getText();
String rst = " -r ", tfRstplt.getText();
String out = " -o ", tfOutdta.getText();
String strp = " -s ", tfStpdta.getText();
if tfStpdta.contains(".csv")
String run = in, rst, out, strp;
else
String run = in. rst, out;
// I want to execute either a .x file or .exe file, depending on if I am
// running the app on windows or mac
run relap5.(x) or (exe) (string run goes here)
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?

View Replies View RelatedEmbedding 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!

View Replies View RelatedI have a little application that I made, it requires that I save data to a file in data/coins.cdp. When I run the application with java myProg in the terminal everything is correct, when I create the executable jar and run java -jar myJar.jar or ./myjar.jar everything also works. Even if I copy the jar to a different location, and run it through the terminal, it still works fine. Things get weird through when I copy the jar to a new location and double click on it, because then no folder gets created and no file is written.
Why is that?
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.
View Replies View RelatedI have tried to get my dinky little program I wrote to be stored as an executable through Eclipse to no avail. It seems I have tried everything else as well, to no avail. I do not want it to go through command prompt, but rather have it be its own entity. As you can probably tell my knowledge of Java and coding is limited, but always willing to expand.

I have one Project -"A".Inside of that I use, .XLS to read data.
Structure - A/src/TestData
Inside of the TesetData - I have placed XLS files.
I have main method in TestDriver class.If I run this in Eclipse, running fine.But after exported to executable/runnable Jar, and ran via command line (command - jar -jar myjar.jar), I see issue: "Exception in thread "main" java.io.FileNotFoundException: srcTestDataTestCaseController.xls"
public static void main(String[] args)
throws Exception
{
ResultSet rs;
rs = readExcelData(testControllerName, sheetName, "");
}
As I use main() method which is static, I am getting error if I write like the below:
public void getXls(){
String testControllerName ="TestCaseController.xls"
TestDriver.getClass().getClassLoader().getResource (testControllerName);
}

I was wondering if their is an easily explainable way to convert a jar for a text-based game that runs off the command prompt into a executable. I would guess there probably is not and the game would have to run off of completely different commands, but I thought it couldn't hurt to ask.
View Replies View RelatedI am totally new to java. How to convert the below java code to an executable file?
var intInterval = 0
function importdata(){
filename = "C:1.txt";
AmiBroker1 = new ActiveXObject("Broker.Application" );
AmiBroker1.Import( 0, filename, "custom.format" );
AmiBroker1.RefreshAll();
}
It simply imports numerical data from 1.txt into an application amibroker. Also this import function has to be in a loop of 60 seconds.
I have made a simple h2 db viewer using jdbc and in eclipse it has a horizontal scrollbar so it works and displays correctly.
When I run the jar from cmd it works as it should but the results all go onto new lines so all formatting is lost and it looks.. ugly...
somehow make it so the console has a forced horizontal scrollbar but dunno how.
I've been trying to deploy my desktop application as an executable jar file but I'm facing the following problem: Whenever I move the jar file from its original build location, my application becomes unable to write to its external files. I initially thought the problem was path related; however, when moved the app can still load data from these files.
The solution is probably simple but for some reasons I've yet to find it .
The app consists of a jar file and a folder named "files" containing text files (such as library.data) to which serialized objects are written.
I wouldn't be surprise if the problem has to do with the xml build file, but all modification I've tried so far have failed. If it is likely that it is the problem, I'll be happy to post a copy of it upon request.
public static void saveLibraryToFile() {
File file = new File(System.getProperty("user.dir")+"fileslibrary.data");
if (file != null && file.exists()) {
library = new Library(sortedAccounts, accountCategoriesMap, accountCategoriesList);
