Is there anyway to create a Java program that runs like most programs do in Windows ,by double clicking on their icons?
Thanks,
Vance

Looks kinda cool. Most java-2-exe programs are usually way too expensive and wont work with GUIs and require other dlls/libraries...

Help required - running a Java program from the command line

Hi,
I have a small non-graphical Java application, packaged into a Jar file. My program relies on classes in another (external) Jar file.
When I run the application from the IDE, everything works fine. However, when I try to run the application from the command line, I keep getting a NoClassDefFoundError for classes in the external jar.
Both the application jar file and the external jar file are in my root directory (C:\).
My command line call is as follows:
java -cp c:MyExternalLib.jar -jar MyApp.jar
Any help greatly appreciated.
Thanks,
Walter

Problem with running a java program from the command line

I have this code:
package pkg;
import jxl.*;
import java.io.File;
public class TestClass {
     public static void main(String[] args) {
          try{
               Workbook book = Workbook.getWorkbook(new File("d:/testWorkspace/excFile.xls"));
               Sheet sheet = book.getSheet(0);
               String s=sheet.getCell(4, 2).getContents();
               System.out.println(s);
          }catch (Exception e){System.err.println(e);}
}I've wrote it in Eclipse, added jxl.jar to the buildpath, and it works fine.
Then I tried to run it from the command line and I did it like this:
D:\testWorkspace\testProject\bin> java -cp \jxl.jar pkg.TestClassThe result was:
Exception in thread "main" java.lang.NoClassDefFoundError: pkg/TestClass
Caused by: java.lang.ClassNotFoundException: pkg.TestClass
...but the file TestClass.class DOES exist in the folder d:\testWorkspace\testProject\bin\pkg\ and the file jxl.jar IS on the root of drive D (like I already wrote, it worked fine inside the Eclipse).
So, my question is: How to run this code from the command line?
I have no idea what went wrong.
Can someone help me, please?

The current directory is not implied in the classpath.
D:\testWorkspace\testProject\bin> java -cp .;d:\ pkg.TestClassor
D:\testWorkspace\testProject\bin> java -cp .;d:\jxl.jar pkg.TestClassI always forget which is right since I never work with jars...

How to run multiple java files concurrently using command line?

Hi,
I have to write a script to run multiple java files and c files concurrently. Say, A and C are java files and B is another binary executable file, I have to make sure they are run in the order A-B-C, then I was trying to run by using
java A & ./B & java C
But it turned out that B could run before A started... Is there any way that I can ensure that A runs before B, and B runs before C by using the command line?
Thanks a lot.

Sorry, I didn't make my question clear enough...
A has to give some output files that B needs to get started,Then B can start at any time--even before A--and just wait for those files to be written. For instance, A could write to a temp file, then rename it to the real name. However, if there are multiple files, and they all have to exist, even this won't necessarily work. There are other approaches that will though.
although writing the output takes very short time,Depends on when the OS decides to give A CPU time, what else is going on on that disk controller and/or network, etc.
B could still run before A finishes the writing, As it can if you sleep for 1, or 10, or 1,000,000 seconds before starting B.
if B can't find the info it wants, it fails to move on. That's why I need to make sure A starts before B.No, you need to make sure A's data is there before B tries to use that data.

How to run a java program without Java Compiler

I have a small project and I want share it with my friends but my friend'pc have not
Java compiler.
for example, I writen a application like YM, then 2cp can sent,receive messege. My cumputer run as Server, and my frien PC run as client.
How can my friend run it? or how to create an icon in dektop tu run a java program..??..
(sorry about my English but U still understand what i mean (:-:)) )

To run a program you don't need a Java compiler. Just the Java Runtime Engine. That can be downloaded from the Sun website and comes with an installer.
You could then turn your application into an executable jar file and start it somehow like jar myYM.
There is also software that packs a Java program into an executable file. I've never used that but one that comes to my mind is JexePack. It's for free if you can live with a copyright message popping up every time you start the program.

Running a Java program without the JRE...

Hi there,
I was wondering whether it is possible to run my java applications on a system that does not have the JRE installed?
Is there a way to compile the java bytecode into an executable - let's say for windows.
Thank you

How to run a java program in the JVM of an already running program?

As far as I know about JVM, each time we run a program a separate instance of JVM is created where the program runs. Correct me if I am wrong.
Is there any way for another program to execute itself in the same JVM?
Currently I am working on JFCUnit which is a tool used to automate swing applications. I am trying to automate JConsole.
If I open "JConsole.exe" through a program and then try to get the handles using JFCUnit, things are not working.
If I use JConsole.jar in JDK/lib and create a new instance of JConsole and then try to get the handles using JFCUnit, I am able to proceed with automation.
But here comes the problem :-
The application which needs to be automated through JConsole requires it to be started with few arguments, which is as follows:
%JDK_HOME%\bin\jconsole -J-Djava.class.path=%CLASSPATH% -J-Dcom.sun.management.jmxremote.ssl=false -J-Dcom.sun.management.jmxremote.authenticate=true -J-Djmx.remote.protocol.provider.pkgs=oracle.oc4j.admin.jmx.remote "service:jmx:rmi://localhost:23791"So this problem can be solved in two ways,
Either
1. JFCunit could be made to recognize the JConsole.exe which would be running is a different JVM.
OR
2. JConsole.jar to be used in a way so that it takes the required arguments, hereby an instance of JConsole would be created that too in the same JVM as that of the program.
I am more interested in the first solution as it would definitely be helpful in other projects as well.
Please let me know if any other solution is possible.
Any kinda solution is appreciated :)
Thanks in advance.

How to run a java program in another folder

Hello!
I want to run for example the java class file in the path ./sourcecode/javafile.class. It works fine if I do the following:
cd sourcecode
java javafile
but it cannot work if I do:
java sourcecode/java
The error it outputs is NoClassDefFoundError.
Can someone tell me how to run a java program in another folder
thanks a lot.

You need to specify the classpath using the -cp flag when running. so instead of
"java sourcecode/javafile"
Try
"java -cp sourcecode javafile"

I've put the appsborg2.zip file in my classpath. I've also copied the entire (1 GB) worth of Java .class files for Oracle apps onto my computer and placed it on my classpath. Is there something that prevents me from testing out my Java concurrent program on my Windows machine from the command line?

i think if u run the ap in the command line then it has to stay open, you could try writing a .bat file then when that is executed it will only open the command line for the program execution (i think)

Is it possible to run a java program without using the command prompt?

Hi,
I was wondering whether it is possible to run a Java program (not an applet) without using a command line in the command prompt?
Basically I want to run a program that will be continually running in the background and hence I don't want to have a command prompt screen loaded up as well - I just want the program to be running in the task bar.
I know how to run the program in the task bar - but I still need to launch the program from the command prompt - is there anyway I can get a program running without having to start it from the command prompt?
Cheers

Or create a desktop shortcut (in Windows) or an application launcher ( in Linux GUI).

URGENT: How to run a Java program from a different directory?

Hi.
How do I run a Java program from a directory that the file is not located in? So lets say im in c:\Java. But the file is in c:\Java\abc\efg\.
What would be the command to run the Java file from c:\Java.
I can't remember it and I need it asap.
Cheers.

If the class you are trying to run is MyApp.class, try
c:\Java\>java -cp abc\efg MyAppThe actual classpath you specify will depend on whether or not MyApp.class is in a package (I've assumed it isn't) and whether or not any 3rd party jars are involbed (I've assumed not).
Edited by: pbrockway2 on Apr 1, 2008 6:42 PM
The command arguments read as "Run the MyApp class using as a classpath abc\efg relative to here (c:\Java)".

How to run a java program using additional jar files

Hi everyone in the forum,
i ve created an app using the hFreeChart in eclipse, so i added them as external jar files and tested the program.
now my problem is that the program should run using a terminal in win and i do not know how can i do to make the command line or the system to find them, i added to the path but i read somtehing about classpath, but i have no idea. if anyone can help?
thanks in advanced

Actually, the best way to prepare a program for regular running is to make it an executable jar file, which means adding a manifest file which contains (at least) a Main-class: and a Class-Path: line. Referenced class libraries typically sit in a lib directory next to the java file. Then you can run it using java -jar myprog.jar.
Failing that create a batch file or link that supplied java with command line parameters including a -classpath=
Using the class path environment results in too much contention between competing values of it.

How to run a java program remotely

hi,
i have a simple hello-world java program on my windows machine.
is it possible to run this program remotely from a linux server?
any suggestions, links to suggestions will be helpful. thanks!

i think that would be a problem for me, so i will need to use some other approach. what i'm trying to do actually is that we have a university server which is set up so that students can have combination fo shell and cgi scripts in their home directory and with that, they can have web pages.
but students cannot use that server to run java applications. so to work around that, i was hoping that i can have my java application, and the database on my own windows machine, and be able to invoke the java program from the shell script on the linux server and once i have my ouptut, i can display that on the web page with CGI script.
is there any other practical approach that i can use to accomplish the above?
