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: Microsoft Windows [Version 6.2.9200] (c) 2012 Microsoft Corporation. All rights reserved.

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.
i have programmed a game using JPanel and JFrame. My App is of this type (if this is relevant to the problem):
public class Main extends JPanel { private JFrame frame; public static void main(String[] args) { new Main(); } public Main() { frame.setSize(WIDTH, HEIGHT);
[Code] ....
The problem is, When i export the file in eclipse as Runnable jar file,and run the exported file, it gives me a blank screen (white default) and nothing is running. Whereas, normal debugging of the game is working quite well.
For my jsp file, the code editor shows no error, but the projects window shows an error. I built my project again, cleaned the project, restart eclipse twice and summoned cthulhu. But my project still shows an error. How do I find the cause.

While going through stpring batch,every where there uses pom.xml. But in my office maven repo is blocked. How to get the jar files .
Is there any way to run pom.xml online and download required jar to my local drive. or how to run a pom.xml file after setting maven, I had done all the same but some unknown issues.
I have a very basic question about the Maven. I compile 2 dependent projects on maven and they have a problem, then I change a code and I recompile the project.
After that in the jar file of this project, I see that the code is the same, the error also shows me that the file is the same ( from the error line i can understand that) ....
This might make me look pretty silly but I was curious if there was a way to make a dynamic web page in java. Basically only using pure Java, with only HTML5, CSS and mySQL.
I have code which query value from database, the use case is the user can enter value as 1,01,11 in database but when the user enter value in xml file he can only enter 11,01,12 in database there is two columns lets say column test1=1 and test2=2 combination of this is 12, which is the value the use will enter in xml, but sometime the use can enter test1=04 than column test2=00 how can i approach this
I got table called card with column crdind,crdpos1,cardpos2 as primary key. The user can enter value as
The rule say if you enter one number in crdpos1 eg 2 than you must enter value in crdpos2 it can be any number 1-9 but if you enter 00-09 in crdpos1 than crdpos2 is 00
The challenge I have is to query this value after they been enter. I have xml file which got field crdpos the use enter 15 which is the combination of column crdpos1=1 and crdpos2=5 ... How can I split the value crdpos and got and able to query in database in two separate column ....

I use a program called eclipse. I want to know how to build a house with the program. We use a pen in java. It is a drawing tool. I dont know how to do it.
I should do, for my academic project, draw from a java project some information, for example, the class name and the relative method, and for each class even the package name where the class is. The information found must be saved an XML files...
I have a gameengine stil partially in the works for pc made in java, I am attempting a port over to java but certain classes and other fuctions are not available for android that there is in java. this means that my render engine, gameengine and a couple of other clases therefore don't work.
My question is, is there anyway of using the gameengine classes that work into the project so that all i have to do is declare within the engine what i want to export for wheather this is android or java. or importing packages from the game engine project and directly linking with the ability of re-writing the odd few classes that do not work.

I'm programming a game in Eclipse using Java for Android. I was wondering if any good example of a Health bar using Images. All I can find is people using the progress bar, but i feel that's unprofessional looking.
My goal is to layer 2 images. 1 being the frame of the health bar, 1 being the value of the health bar. I figured it would be something like moving the value health bar image few pixels over depending on the variable of health.
