I've added a small program that reads from a .txt file to the windows 8 startup folder using a .bat file ... The problem I have Is I've used relative paths for text files In the program and It doesn't work unless I change them to absolute paths.
The .bat file Is basically java -cp[absolute path to program directory] ReadAFileApp . Is there something (most likely yes!) I'm missing here ?
When my app starts up is it possible to create a blank xml file in the c drive? so I can use it later on down the line
View Replies View RelatedAt startup, the class containing your main method is loaded. It loads all classes that it needs. Each of those loaded classes loads the classes that it needs, and so on. That can take a long time for a big application, frustrating the user. You can give users of your program the illusion of a faster start with the following trick. Make sure that the class containing the main method does not explicitly refer to other classes. In it, display a splash screen. Then manually force the loading of other classes by calling Class.forName.
I'm not sure if I got this right - the tip amounts to suggesting to load all the classes altogether in the main method while displaying the splash screen?
Second, how can the main method not refer explicitly to other classes? It has to create some objects after all...

I am having some trouble with a Java program. I have a txt data file, which I will display, that I need to add into two separate arrays. The text file is 8 lines long that is supposed to go into two separate 4x4 matrices. A little background info on this program, reads in two arrays, compares them and outputs the largest elements of the same index and outputs them in a separate array. I somehow cannot seem to figure out how to do this. My code is below:
Data File:
2 7 6 4
6 1 2 4
9 7 2 6
8 3 2 1
4 1 3 7
6 2 3 8
7 2 2 4
4 2 3 1
Code:
public class prog465a {
public static void main(String[] args) {
Scanner inFile = null;
try {
inFile = new Scanner(new File("prog465a.dat.txt"));

View Replies View RelatedI have a UI that uses fx:include to include a handful of nodes in a StackPane. So far I have less than 10 panes and I can already notice a delay of ~3 seconds (on an older machine) when the initial scene is built. It's especially noticeable because I'm using a pre-loader with a progress bar. The progress bar runs smoothly until the pre-loader calls start() on my application. After that, the scene is built on the application thread, so the progress bar doesn't get any more updates. It looks like the progress bar freezes until the main scene is built and shown.
I was hoping I could build the main scene on the JavaFX launcher thread, but that doesn't work. I tried it and, not surprisingly, get an exception for not being on the application thread. What are the options, if any, for making an application's start up feel a bit smoother?

View Replies View RelatedI have 2 different apps, one of them is a java desktop app and the other one is a c# web app. which uses java applet in order to e-sign. The problem is desktop java app requires 1.5.0_14 and on the other hand web app. requires 1.7 and higher version of java.
I installed both java 1.5 and 1.7 versions on my PC. In order to run desktop java app., I go to C:Progra~2Javajre1.5.0_14in and run javacpl to disable 1.7 and enable 1.5. Then I make a shortcut to javaws 1.5.0_14 to my desktop and add the jnlp of this java app to the target of javaws shortcut. After those settings, the java desktop app. runs.
Now I need to also run the web app which requires 1.7 java. In order to run this app. properly Java 1.5 should be disabled, 1.7 enabled on the Java Control Panel settings. Problem is when you run this web app. the settings for 1.5.0_14 breaks down, I mean all of the java versions become enabled in javacpl under C:Progra~2Javajre1.5.0_14in directory. If I restart my PC, I need to reset the java versions. Is there a way to make this happen without a pain in the head?
By the way, I tried to use batch files etc. but not succeded.
Im running an eclipse application in my machine. I have two queries
1. I would like to know how to check the default heap size that the jvm is using to run the application.Im using a windows machine to run the java application. I tried to check the default heap size by the following way
ControlPanel--->Programs--->JavaSetting--> JavaTab -->View Button ---> JavaRuntimeEnvironment settings window ---> Userstab --> Value under RuntimeParameters
But in my system, there is no runtime parameters defined. Is there a command that I can execute via command prompt to check the default heap size in my machine.
2. How to increase the heap size parameter and run the eclipse plugin application from command prompt. For eg: To increase the heap size and execute the jar file we use the below command java -Xms64m -jar MyApp.jar. I would like to know how to set heap parameters and execute my java application which is an exe file. I tried to execute use the below command, but the command prompt doesnot recognise the command
java -Xms512m iepsd.exe
Where iepsd.exe is my java application.

At our company we run a third-party Java-based GUI application on one of our Linux server machine, displaying the application to our local Windows work stations using the Cygwin X Server.We noticed a few problems with a new version of this application and was able to narrow it down to the following conditions:
1. Java Swing application running on a UNIX host;
2. Java used is 1.6 (problem not noticed when using Java 1.5)
3. Displaying to Cygwin X server (I've heard other windows-based X servers have the same issue, but I don't have access to any others at this time).
If we run the application natively on Windows, I'm told if the application runs on the Linux host and displays natively to that machine's display there are no problems (although I'm not able to verify this myself).The problems are:
1. Any new frame/dialog is opened in the geographic center of the dual displays, rather than in the middle of one or the other;
2. Any attempt to drag the window to a different location on the display seems to work, but as soon as you let go of the drag, the window snaps back to the original location. This only happens the first time you try to move each window.
3. Drop-down controls (JComboBox, for example) just close back up as soon as you click on them. If you click and drag the mouse to attempt to make a selection, no selection can be made.
Are these known problems using 1.6 on UNIX displaying to Windows-based X Servers?
The only real problem is number 3. I expect that if I put more work into the window placement, I should be able to get past number 1. Number 2 is just a minor annoyance.The following is a simple Java Swing application which when run in the correct environment will exhibit the problems.

View Replies View RelatedI don't really understand the question is the thing. Its about calling a file in the java program. I read the book and i can see how to call a file from a directory and how to save it and edit it but I don't understand what the instructor is asking for. Mostly what files need called and println.
Assuming the object that manages output will be called writer, write a statement that opens a text file called home.html for output by println statements.
To be file-writable and file-readable, an object must be an instance of a class that implements___________.
Write a statemnt that opens a file for input of objects and assigns a reference to the connection to ObjectIn. Assume the file is in the current directory, with the name automobiles. data.

How to deploy Java Swing application as windows software. I have tried the following to do this :
I have created jar file for my project after that created exe file using Launch4j and Advanced installer, exe file produced by both software are working fine but those are placing the jar file inside that exe file, My problem is any one who has that exe file can extract and view the source code by decompiling java class file. Is there any way to deploy java application without decompiling the code.
