I 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.
View RepliesI'm trying to run a command line executable file using java but there is no output. On the task manager a conhost process opens when the application is run. I've tried
1)try {
Runtime.getRuntime().exec("D: est.exe");
} catch (Exception e) {
e.printStackTrace();
}
2)String[] cmd = { "D: est.exe"};
Process p = Runtime.getRuntime().exec(cmd);
p.waitFor();
and
3)//Runtime.getRuntime().exec("D: est.exe", null, new File("D:"));
same thing happens i.e. nothing happens.
I want to know is there any way to run java program without installing jdk.
I want to run my code on system which dnt have jdk installed on it. is it possible??
I wrote some java applications on my computer, which is 32-bit Ubuntu 12.04 LTS. Could the application run on both 32-bit and 64-bit versions of linux? Or could it only run on 32-bit versions of linux?
System.out.println(System.getProperty("sun.arch.da ta.model")); // outputs 32
I would like to know if I run it on a 64-bit version of linux if it will take advantage of the performance advantages of 64 bits.
I 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?
when I am programming let say in VB using Visual Studio, finally I build .exe file that can be run on all Windows by double click.For Java I am using Eclipse and to run those apps I am using run from Eclipse.How I can create a sort of "executable" for my Java app that I would be able to run it by file click on Windows or Linux?
View Replies View RelatedI am wondering if there is an easy way to create a java exe(cutable) binary, by packing the JRE and ship it like a compiled C++ bin file? I know JAR is good but, I still prefer to create a standalone install - free exe, no matter if the user has or has not Java installed on her PC.
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 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

i have a program in UNIX directory /home/me/java/src
package bin;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
I have manage to compile it successfully(class file will be in bin directory) using command below: javac -d /home/t_bmf/java/bin HelloWorld.java
My problem now is how would I execute the class in bin directory in UNIX? I already tried different ways on how to execute it as suggested in my internet research The one I tried is this:
java $CLASSPATH:.:bin/HelloWorld
but I got this error message:
Exception in thread "main" java.lang.NoClassDefFoundError: :/:bin/HelloWorld
Caused by: java.lang.ClassNotFoundException: :.:bin.HelloWorld

I am trying to run my program through netbeans and I get a message:
...build-impl.xml:1048 the module has not been deployed.
see the server log for details.
The corresponding line in the xml document is:
<nbdeploy clientUrlPart="${client.urlPart}" debugmode="false" forceRedeploy="${forceRedeploy}"/>
And in the server log there is a long list of comments, the first which looks to be of significance to this issue is:

javax.naming.NameNotFoundException: Name [comp/env] is not bound in this Context. Unable to find [comp].
There are others further down the list which might also be significant such as:

The corresponding line of code for the first warning that I listed is for the DataSource object and I wrote it as follows:
dataSource = (DataSource)
ic.lookup("java:/comp/env/jdbc/trans_board");
I'm pretty sure the issue has something to do with connecting to the database since it ran fine before I added the database related code.
I had some questions about a theoretical java program. Say you had a java program on a linux server/pc that referenced a folder on that server. And say you had a Client PC (Windows) that had a share folder to that java program.
If that windows client PC tried to run the program would it run (with a GUI if it had one) and would the main directory of the java program still be on the linux server or would it be on the windows computer since that is the computer that is running the program?
Basically I have a program I am trying to find the best way to run it remotely on a windows computer but it references files on the linux server it is located at and needs to put files it creates there as well. I am just trying to make sure I understand my theory here on how the program will run if it IS run remotely.
I made a software using Netbeans and javaswing. Accidently i deleted my main file which contains my main class and main method. Just to test, i tried to compile and run and it worked but the style of my buttons and windows has changed. So, what happened? How can i change the style of my programs?

I have a program that is a XML-parser, and it works fine when I'm running it from NetBeans. But when I create a JAR-file and run the very same program, it cannot find the xml file. Consider this small program that addresses my problem:

I was doing some exercises of a java tutorial website, and realized when I ran the code that they had , my program just kept running with no result, why is this? It just hangs.

It is working fine when i run in Eclipse, but is giving error when i run in cmd.. What i need to do to over come this..
Can we cance/stop a long running database query execution instantly so that we can do any another task.
As i know swing uses a single thread i,e Event Dispatch Thread (EDT), But at the same time we can use Swingworker class for better use of UI. When we use Swingworker class the process goes to a different thread and our basic UI is not Frozen. Infact we can do another task. But what I want is I want to stop of cancel the execution of swingworker thread ( Because I that thread takes long time to execute). How can I do that??
I used ProgressMonitor and in the cancel option i canceled the task ( worker.cancel(true) also i closed the connection and statement for executing the database query using stmt.close() and conn.close() methods.
But it does not work. How to cancel a long running database background process in a Java Swing Program.
I've been playing around with this for about an hour.
Java Code:
Runtime runTime = Runtime.getRuntime();
try {
Process process = runTime.exec("notepad");
} catch (IOException e) {
e.printStackTrace();
} mh_sh_highlight_all('java');
So that works. Notepad will open.
However, I'm trying to get other programs to open. Specifically, this program: C:Octave3.2.4_gcc-4.4.0inoctave-3.2.4.exe...However, using that in place of notepad doesn't work. I'm assuming that there is some sort of system variable that explains why simply typing "notepad" works? As if you type notepad into the run box, notepad will open. Soo does that snippet work by going through some sort of system variables?How would I go about opening other programs, such as the one I referenced above.

I am running the this from a Linux command line , in the cmd first i use :
javac -classpath acm.jar Chap6_ex1.java
end then :
java -cp .:acm.jar Chap6_ex1
The output i m getting after second command is :
Exception in thread "main" acm.util.ErrorException: Cannot determine the main class.

I know the problem is from the RandomGenerator class in packet acm.util.* but i dont know how to fix the problem . Every other program has worked . What I am missing or how this whole issue of packet importing works when running a java file from cmd ?
I have built a Java app that uses SQLite (sqlite-jdbc-3.8.7.jar). Running the jar file on windows works as expected however, trying to run it on Ubuntu Server 14.04 has turned into quite a task!
I put together a brand new machine in VirtualBox for testing. I installed Java (sudo apt-get install default-jre) and have installed SQLite (sudo apt-get install cl-sql-sqlite3 sqlitebrowser). I created a new sub-directory within my home directory and copied over the jar file. From terminal, I then run the command: sudo java -jar ProductionView.jar and I receive a java.lang.unsatisfiedlinkerror. For troubleshooting, within the app, before making a connection to the db, I have printed out the location of where the db is to be created and it is correct (see attached pic). Is there more that needs to be configured before I can run this app on Ubuntu? I have posted the relevant code below :
(AppDatabasePath() is what is printed in the image...).
public static String AppDatabasePath() {
return AppPath() + APP_NAME + ".db";
}
public static String AppDatabase() {
return "jdbc:sqlite:" + AppDatabasePath();
