  • 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"

  • 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.

  • 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 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.

  • 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 via a batch file,which is called from a webserver

    REM This batch file runs the Spider with the [-v] option.
    REM Lines 51 through 54 are simple DOS commands..they call the Spider
    REM The location of the Spider package is the important piece of information here...
    REM a batch file has access to the whole computer where the server resides.
    setlocal
    set JDK=C:\j2sdk1.4.1_01
    set PATH=%JDK%\bin;.;%PATH%
    CLASSPATH=%JDK%\jre\lib\*.jar;.;%JDK%\jre\lib\ext\*.jar;.;%CLASSPATH%
    java spiderpackage.EntryPoint -v
    endlocal
    I am trying to call this batch file from my web server but I am unable to capture the result.I tried to append the result to a file but It writes nothing to it.What should I do to proceed?

    I am not entirely sure if this is analogous, but I once wrote a PHP script uner Linux that invokes java and returning the output. I found that it was necessary to pipe the output of the Java program from stderr to stdout in order to properly receive it in PHP. The command would be as follows:
    java spiderpackage.EntryPoint -v 2>&1
    The pipe syntax (2>&1) should be exactly the same under MSDOS. So add that, and then continue as normal (appending it to a file or whatever else you want to do). Hope that helps

  • 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?

  • 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

  • How to run a Java program

    Ok, well I'm new to the world of Java and am excited to learn. I know C++ pretty well and I think that is what is kinda confusing me right now. When I made a simple "Hello world" app and tryed to run it nothing happens. I double clicked on the class file. What I really what to know it how to set up and run a basic application how anyone would. It's a little differnt than just compiling and running an .exe and I think that is what is kinda confusing me as I said before.

  • How to run executable Java app from command line: No Main( ) method

    This is the opposite question from what most users ask. I have the Java source code and a running Java executable version of the program in a windows environment. I don't want to run it in the normal way by double-clicking on it or using the executable. I need to be able to run the same application from the command line. If I can do this, I can then compile and run the code on my Mac, too, which is what I am ultimately trying to accomplish.
    Normally, this would be easy. I would look for a Main method, normally public static void main (String[] args ) or some variation. I cannot find a main() anything, anywhere when searching the files. There must be some windows executable that links to the Java classes. It's very clever, no doubt, but that's not helping me.
    I am trying to run what I can determine as the Main class, with a standard command line call, but that is not working either.
    It is a Java graphics program, so mostly Swing container stuff.
    I am not finding a manifest.txt file, telling me where a main method is, nor anything about the Main Class. There is no readme file for the program.
    Any insight that would point me in the right direction? What should I be looking for?
    Thanks in advance, Bloozman

    It's possible there's a clever Windows executable that runs the class. But if it's a plain old Java class then there's a good chance there's a constructor. Look for that; it's possible you may be able to start by writing another Java class that creates an instance of your mystery class.
    When you have that done, try running it. It's possible that just creating an instance might be sufficient to run it. Swing programs are sometimes written like that. If not, then start looking for methods with names like "run" or "go" or "start" that your little controller program can call.

  • 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.
