I'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.
I am trying to apply for a job in testing the following java application.I have received a tool written in Java and I need to run it with the command line:
Can we set the class path for one level down the current directory? My structure is like
binlibresourceshexicon.cmdinside the folder dist.
In this case I could run the .cmd file which has java -cp .;lib;resources client.Test .
c: rycpdist>java hexicon.cmdBut if i put the .cmd file inside bin as like this and run as c: rycpdistin>java hexicon.cmdI am getting this error Error: Could not find or load main class
Is there any possibility to set the class path in this case
I have downloaded jns-1.7 & tried to run an example program "Simulator.java" by specifing the jar classpath while compiling as "javac -cp <path-to-jns-jar-file> Simulator.java". But i got 21 errors as follows:
Simulator.java:3: error: package jns.command does not exist import jns.command.Command; ^ Simulator.java:4: error: package jns.element does not exist import jns.element.Element;
[Code] ...

I am trying my hand on JNS as i need to deveop a key-distribution scheme (random Key-Distribution scheme) using a simulator. As i have experience in java, i thought to use JNS instead of NS2/NS3 which seems very complex to me.
I'm developing a JavaEE system with several applications on a Weblogic AS (10.3.5) using Eclipse indigo with OEPE plugin. I turned my computer off, turned it back on, started the eclipse, and all of a sudden I get class-path errors all over the place (didn't change a thing).
Now let me get this straight:
1. Say I have an application with one EAR project that contains an EJB project and an EJBClient project (both in the deployment assembly). 2. I have written a new regular Java project, and I want to use it in both the EJB and EJBClient projects (it needs to be visible to them). 3. As far as I know, I can simply add this Java project to the EAR project's deployment assembly, and it will be visible to the EJB and EJBClient projects. 4. This has been working for me so far, but now I get class-path errors and I have to add this Java project to the build path of each project.
How should I set the class-path when using JavaEE technology in Eclipse?
I am copying the xml files from one folder to other folder, in the source folder, i have some files which have some content like "backing File="$IDP_ ROOT/metadata/iPAU-SP-metadata.xml" but while writing to the destination folder.i am replacing the "$IDP_ROOT" with my current working directory. The entire copying of files is for deploying into tomcat server. The copying is done only when server starts for the first time.Problem: If i change the folder name from my root path in my machine after i run the server,the entire process will be stopped because the destination folder files already contains the content which is with existed files names or folder names.
So i want to change it to relative path instead absolute path. What is the best way to do it? Please look at code below:
[ // Getting the current working directory String currentdir = new File(".").getAbsoluteFile().getParent() + File.separator;
i am using a frame over which i am loading a dialog. The singleton dialog holds a progress bar. I have created my own swing worker. i am controlling the construct method of swing worker(which functions like doInBackground method).I am trying to call hidedialog from an external file.

Cannot reinstall java on this windows xp. Get an error -1 and install didn't complete. There are no java versions installed and apparently no java control panel either.
I 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.
I want to create a Web page which can monitor and display the status of Schedule Tasks setup on different remote machine. This Dashboard should also has the capability to re-run the schedule task.
I know that I can achieve this via Runtime class by running schtasks /Query and get all the details. But I just wanted to know if we have any other better way to do this.
I manage a small company through our bank's online system, that uses java, but I can't access it through any browser , they all give the same issue; after I choose the certificate file on my PC, nothing happens.
If i dual boot Ubuntu on my PC it works, so it's clearly something with the Windows installation.
Things tried :
- Reinstall Java, multiple times - Clean anything Java and Oracle related in my PC (except registry, I don't know how to fuzz with that) - Different browsers
Is it possible to edit hosts file in java program? I tried it but I'm getting "AccessDeniedException". I need to have permissions for it, but can i somehow set the permissions in java program for current user?
I've just installed the last Java kit JDK plus netbeans and I've done my first project in Java. It is running perfect from command line<but is is difficult to execute each time from there my tests> but I couldn't run the jar file from windows with double click he jar file even I've spent 3 hour on google to find different methods (registry modifying, control panel/program running in windows, a patch file etc, ) ....
I have an applet and start some process on Windows from applet. When I start this process just from another code(test), this code works fine and process runs from rt.exec() to proc.destroy(). When I use html call for applet - process runs only for 5 seconds every time (!!!) and then just alive, doesn't work, to proc.destroy(). This is really interesting for me (newbie in applets). I think, this issue caused by AccessController. I use Windows, medium Java security lever and applet is self-signed. It asks me to 'allow', applet works.Here's the code:
I'd like to know if there's a way to embed Windows Painter (mspaint.exe) in a browser. I'm not sure it's possible with Java and if it doesn't, any relevant reference to this subject.
In the image, the color of the frame of the window/JFrame is black. My question is that can we set the color of this frame, or is it just provided by the operating system and whatever color is default color of windows in an operating system will appear in our application?
I am talking about the frame, the boundary in the JFrame container which contains the close, maximize, and minimize buttons.
When I run the following code from Java HeadFirst, everything goes fine but along with one error ( i don't know is it an error or exception, or some other windows stuff). The code is
import javax.sound.midi.*; class ExceptionHandling { public static void main(String[] args){ ExceptionHandling o = new ExceptionHandling(); o.play();
[Code] ....
And what I got on cmd ( I am using Windows 7) :
Jaspreet javac ExceptionHandling.java Jaspreet java ExceptionHandling Jun 11, 2014 5:19:40 PM java.util.prefs.WindowsPreferences <init> WARNING: Could not open/create prefs root node SoftwareJavaSoftPrefs at root 0 x80000002. Windows RegCreateKeyEx(...) returned error code 5.

What is meant by code in blue? I know its some message from windows os and not from jvm. but i didn't understand it.
editing Slideshow Gadget file (Win7). Unfortunately, I've no coding experience so that's why I can't find solution for it myself. What I've dreamed for is slideshow on my desktop where I can see motivational pictures that would change once per 30 mins. Unfortunately windows gadget doesn't have such option (5 mins max) and it is too small for my needs. I tried to edit file by myself but I couldn't recieve results I wanted.
#1 when I tried to add 30 mins option in scroll menu the program wouldn't even start.I changed this:
var pictureArray= new Array(); var selectArray= new Array(); var slideTimeArray= new Array( ["5 " + L_SECONDS_TEXT, 5], ["10 " + L_SECONDS_TEXT, 10], ["15 " + L_SECONDS_TEXT, 15], ["30 " + L_SECONDS_TEXT, 30], ["1 " + L_MINUTE_TEXT, 60], ["2 " + L_MINUTES_TEXT, 120], ["5 " + L_MINUTES_TEXT, 300]);
[code]....
#2 When I tried to change size of slideshow it wouldn't fit in border -->I changed this
var maxDockedWidth= 120; var maxDockedHeight= 90; var maxUndockedWidth= 320; var maxUndockedHeight = 240;
[code]....
If the size of slideshow could be 534x333 px that would be perfect!
