View Replies View RelatedHow To Set Different Java Versions For Different Apps On A Windows PC
Nov 25, 2014I 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.
How To Identify Default Java Heapsize In Windows
Sep 26, 2013Im 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.

May 7, 2014I am developing a JavaFX application under Java 8 on my Ubuntu 14.04 (32 bit) system.

Swing/AWT/SWT :: Running Application Using Java 1.6 And Windows-based X Server
Apr 15, 2011At 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.
import java.awt.EventQueue;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;

Swing/AWT/SWT :: Embedded Browser In A Standalone Java App Running On Windows
Aug 24, 2014I have an embedded browser in a standalone java app running on windows. The browser calls up web pages over the internet with no problem.
import org.eclipse.swt.browser.Browser;
final Browser browser = new Browser(group01, SWT.NONE);
browser.setBounds(0, 0, 1000, 400);
browser.setVisible(true);
browser.pack();
browser.setUrl(texturl.getText());
I have a C executable which captures and documents network traffic. I communicate with it by entering http://27.0.0.1:6500 into any browser (it works with them all). It responds with a simple html form (three buttons, a tick box, a label, and one text box).However I cannot get it to work with the embedded SWT browser.

Apr 5, 2014 Is it possible to launch windows, specifically 8.1, directly into a java based program which would serve as the password entry screen? That is to say, instead of using the standard windows screen, could a java based alternative be used?
I have the source code used on jurassicsystems.com. I would absolutely kill to have a tweaked version of this system act as my password entry screen. It is literally something Ive wanted to have done for ages, and this emulation finally means it may be possible.

Class Path With Windows 7
May 28, 2010I've just got a new computer and i tried to set the class path the way i did with windows xp but it's not working. This is what i have done. I added a Path variable to user variables and added C: Program Files (x86)Javajdk1.6.0_20/bin as the variable value. But when i got to command prompt and type javac HelloWorld.java it just tells me javac is not recognised as an internal or external command.
Also another problem is after trying this and it not working i tried to add a path to the system variables. I added a new path variable but i think once i did that it deleted the one that was already there. Is that going to mess up my computer? What the default path variable for windows 7 is?i've got the right destination as i typed cd to change directory and when i typed C: Program Files (x86)Javajdk1.6.0_20/bin it changed to that. And i noticed if i typed in the destination wrong its just made an error.
Two Windows Are Being Made Of Game
Jan 19, 2014I have a game which is very simple: it is two images, and one needs to reach the other. Once it does, it resets. I have a class which holds the two images, and another which holds the game. My images class extends my game class. The problem I am having is that when I run the program, not one, but two frames appear. One is the perfect game, working perfectly, and the other is the game without images. I want the one that is the game without images to simply stop appearing. I believe it is appearing because my class that displays the image is extending the game class, but I can't not extend it because if I do I get a whole lot of bugs and errors.
Image class:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

- Clean anything Java and Oracle related in my PC (except registry, I don't know how to fuzz with that)
