Running a java application in command prompt

hi, I'm new to this forum.
I would like to know what exactly needs to be specified to run a java application in a normal DOS command prompt.
I know it is something like:
javaw -classpath .\class GUI.applicationGUI
where applicationGUI is the main class, right? What else do I need to do, since I have some other non-GUI classes that I need, inside the class folder ?
Thanks for your time.

You need to import those classes. And you need to make packages.
In classes 1, 2 and 3 put:
package class;
In class 4 put;
package class.GUI;
Then you need to make the connection:
In classes 1,2 and 3 put:
import class.GUI.*;
In class 4 put:
import class.*;
Compile each directory separately while in the respective directory. javac *.java
Then go back to the directory above the directory "class" and run
java class/GUI/name_of_file_containing_main_method

Running eclipse java project on command prompt

Hi all,
I have one simple java project and that is very well running in eclipse. I have added some external JARs to that project. It performs this job- it creates connection to server, and listens to the signals from server.
My question is - how do I run that java project on command prompt?*
I want to run that using ANT or simply I want to make a JAR file so I can execute JAR on command prompt. I created JAR, but it doesn't contain external jar which I added to the project. So I was not able to run that project.
Can you please tell me any of the method - using ANT or by making JAR?
Also can you be little bit more explanatory in reply?
Thanks

I want to make a JAR file so I can execute JAR on command prompt.This is very likely a good way to proceed. It is explained in great detail in Sun's Tutorial in the section on [Packaging Programs in JAR Files|http://java.sun.com/docs/books/tutorial/deployment/jar/index.html].
I created JAR, but it doesn't contain external jar which I added to the project. So I was not able to run that project.Yes - the jar file you create has to know about the classes and other resources in that external jar. Otherwise, at runtime, the program will not be able to get at the stuff it needs. Usually you don't include that other jar (or its contents) in the jar file you are creating. Instead you provide your jar file with a manifest that describes the other jar's location. Details are also in the tutorial.
One thing to note is that Sun's tutorial provides a lot of explanatory, conceptual, material. To that end it keeps the context simple and transparent by describing the steps as they would be carried out by someone working at the command line. The Eclipse documentation and forums might provide a more click-this-drag-that "explanation". If you do follow the method in the Tutorial and get stuck, post a description of the actual commands you used and their outcome.

Hi,
Are you able to start the Standalone Agent(KANBAN) and test it in the Topology?
Check the value of the ODI_MASTER_URL variable in odiparams file(at the path <ODI_HOME>\oracledi\agent\bin) of the agent.
Specify the full the JDBC URL properly not like localhost(until the DB is on same machine as your ODI).

How can I run a java-application on starting of Windows 2000

How can I run a java-application without any user on starting of Windows 2000?
For example, if the computer is restarted and nobody enter into it yet, my java-application should run anyway.
How can I do that?

Hi, you have to put it in a Windows service.
To do this you have a program, Srvany.exe that allow to insert a .exe or .bat program in a Windows service.
For example, i develop a program, TomcatGuardian and i put it in a service because i need to run it in a server without Administrator logged in.

Ivan.

Running a java application from a java application

Running a Java application from a Swing GUI

Hi,
I was wondering if there is a simple way to run a Java application from a GUI built with Swing. I would presume there would be, because the Swing GUI is a Java application itself, technically.
So, I want a user to click a button on my GUI, and then have another Java application, which is in the same package with the same classpaths and stuff, run.
Is there a simple way to do this? Do any tutorials exist on this? If someone could give me any advice, or even a simple "yes this is possible, and it is simple" or "this is possible, but difficult" or "no this is not possible" answer, I would appreciate it. If anyone needs more information, I'll be happy to provide it.
Thanks,
Dan

I don't know if it is possible to run the main method from another Java app by simply calling it...
But you could just copy and paste the stuff from your main method into a new static method called something like runDBQuery and have all the execution run from there.
How does that sound? Is it possible?
What I'm suggeting is:
Original
public class DBQuery{
public static void methodA(){
public static void doQuery(){
methodA();
public static void main(String[] args){
// Your method calls
//Your initializing
doQuery();
}Revised:
public class DBQuery{
public static void methodA(){
public static void doQuery(){
methodA();
public static void doMyQuery(){
// Your method calls
//Your initializing
doQuery();
// No main needed!!
//public static void main(String[] args){
// Your method calls
//doQuery();
//}

Is it possible to run a java application within a web browser?

Hello everyone here! I have a question about running a java application within a web browser and I would appreciate it very much if anyone here can give me some answers.
I have a standalone java application written with AWT. Basically this free application lets users to select spectral lines from a big file based on some criteria and plot those selected lines. Yes, it is a very simple application. Now I want to run this application within a web browser so that users don't need to download the application from the ftp site and thus don't need to install in their machine. Is it possible to run this application within browser? If yes, can we get the same plotting function as we run the application separately and where should I start out?
Thanks in advance!

Can we run a java application using Runtime.exec()?

Can we run a java application using Runtime.exec()?
If yes what should i use "java" or "javaw", and which way?
r.exec("java","xyz.class");

The best way to run the java application would be to dynamiically load it within the same JVM. Look thru the class "ClassLoader" and the "Class", "Method" etc...clases.
The problem with exec is that it starts another JVM and moreover you dont have the interface where you can throw the Output directly.(indirectly it can be done by openong InputStreams bala blah............). I found this convenient. I am attaching part of my code for easy refernce.

Proble regarding running a java application

hi guys
i'm new to java environment .
when i'm running a java application in a console ,
it is not able to give output in other directories.it is working only in c:\j2sdk\bin.
i think its the problem of setting classpath.
can any one help me hw to run java program in any folder.

You need to add that directory to your PATH. Follow
the installation instructions more completely.Howdy sheriff Warnerja! How's life in the Schmuckville Home of the Ball-less? Any leads regarding the dot flasher case? I see you're on the PATH.

Running a Java Application in Windows

Hi, Can anyone tell me how to run a Java Application in Windows? I've tried to run it using TextPad 4.5 but it gives me an exception saying it can't find a class defenition. I'm actually using IBM VisualAge for Java to develop the app and it runs fine INSIDE VisualAge and I've exported my compiled class files and so on, to run it stand-alone in Windows. I'm using some custom objects and inner classes, could these be the problem?

YES! SUCCESS! I exported my class files from VAJ and along with the manifest file that it adds automatically. I opened up the jar with Winrar, extracted the manifest file and added the Main-class: header pointing to my executable and then put it back in the jar with winrar. And PRESTO! I can now run it with javaw! Thanks for your help peeps...

I want to run a java application once only.Pl help.

i want to run a java application once only.
i.e. if some application is running on Win NT OS then that
particular appliaction again should not run,but other java application can run.
Pl help with some sample code.
Thanx.

Hi,
I if understood your question then your requirement is to run the application when the system is on.If this is the case then you can configure your OS schdular to do the job an let the OS do it.You can
write the java code for this but that will require to run on the OS layer,so better to configure the schedular setting.....But then for some other requirement it cannot be useful....
think...

Running my application from command prompt

Hi im a student and kind of a rookie. My program runs fine from eclipse but when i run from command prompt it gives:
Exception in thread "main" java.lang.MoClassDefFoundError: Mainclass
This is what i am typing: java Mainclass. And i am sure i am in the right folder. I know it gives the same problem when you are not in the right folder. ALso my program uses jre5.0 and it runs fine on eclipse.
Any help greatly appreciated

From the directory containing Mainclass.class try java -cp . Mainclass The effect of "dash cee pea space dot space" is to
set the classpath to the current directory.
