Call a jar in the command

Hi, I generated a jar out of my java project, and I want to invoke it in the command.
The problems are:
1. The class I want to turn to is in a package.
2. I want to invoke specific method in it
My class that contain the method to invoke is: myClass
The method I want to invoke inside myClass :myMethod
The jar file name is : myJar
The package name is: myPackage.
Should I write in the command:
java -jar myJar.myPackage.myClass.myMethod ???
Thanks.

Go through [_this tutorial_|http://java.sun.com/docs/books/tutorial/deployment/jar/index.html] and learn about the jar manifest.
Or include the jar in the -cp (classpath) flag and use a driver class with a main(...) method that loads 'myClass' (should be MyClass, class names should always start with a capital letter) and invokes the method.

  • Running a jar from the command line

    I am trying to run a Jar from the command line. I have a number of classes in a package called "trainnn".
    I put all the classes into a jar
    jar cvf name.jar trainnn\*.classI then creat a file called mainClass.txt with the line (with a blank return line after it, where QueryMatch has the main). This file was placed in the same directory as the package and the jar file
    Main-Class: QueryMatch
    then
    jar cmf mainClass.txt network.jar G:/TrainNN/src/trainnn/QueryMatch.classthis worked fine.....but it is from here I have problems when I try run the jar
    java -jar network.jarbut get this error.
    Exception in thread "main" java.lang.NoClassDefFoundError: QueryMatch
    I cant figure out this error, I have tried specifying the exact path in the mainClass.txt file but that didnt work.
    Any ideas
    Thanks in advance.

    Hi,
    To start a java app in the command line with "java -jar yourJarFile.jar", the jar needs to have a mainfest file "MANIFEST.MF" in a folder called "META-INF". The manifest file would have to contain the name of your starting class, e.g. it could look like thisManifest-Version: 1.0
    Main-Class: com.yourCompany.yourProject.YourClass Hope that helps. Cheers, HJK

  • Calling a newly deployed EJB from an EJB gives a NoSuchMethod Exception if the jar of the newly deployed ejb is not in the classpath

    Hi ,
    I have an EJB A which is already deployed when the server starts. A second ejb
    B is deployed at a later time.
    EJB A calls methods in EJB B. I use reflection in EJB A to call methods in EJB
    B.
    I get a NoSuchMethodException when I call the create method in the Home object
    of EJB B. If I add the ejb jar file to the classpath before the server starts
    then it is able to resolve the method.
    The problem is the EJBs which are called from EJB A is not known before the server
    is started. New EJBs can be deployed at runtime and EJB A should be able call
    the methods in newly deployed EJB's.
    I also use the URLClassLoader to load all the classes in the jar file of the newly
    deployed EJB in EJB A and it still gives a NoSuchMethodException because it cannot
    resolve the stub class.
    My error log is shown below.
    This is an urgent issue.

    Hi,
    I am attaching a test case. This test case actually demonstrates a security bug.
    Unzip the file and modify the StartWeblogic.cmd in domainA to not refer to the
    SampleRemoteEJB.jar in the classpath. If u run the test client under the client
    dir u will see a NoSuchMethodException.
    The reason is it is not able to load the dynamically generated stub file.
    Initially I had the getMethod and it didn't work. You might have to modify the
    files to suit ur env. The easier way is to run th edomain wizard and create 2
    domains. Run the servers in development mode and place the jars under the applications
    dir
    Thanks

    Why is it giving you a NoSuchMethodException instead of a

    Can you post the code from SampleConctorEJB.java, line 181?
    Try changing your call to getDeclaredMethod() to getMethod().
    getDeclaredMethod() searches only the class you called it on, whereas
    getMethod() traverses to the superclasses and interfaces. You onlyneed
    getDeclaredMethod() when you're accessing a nonpublic method.
    Not sure if this will help, but it's worth a shot.

  • Running jar files from the command line

    I have always felt it would be useful to run a jar file from th command line in EXACTLY the same way as an EXE. On some systems, typing MYAPP.JAR will run the app, but doesn't output and command line data, so it only works for GUI apps. I've come up with a tiny C program that runs java -jar xxxx.jar for you.
    #include <stdio.h>
    #include <string.h>
    #include <process.h>
    void main(int argc,char *argv[])
         char cmd[1024];
         strcpy(cmd,"java -jar ");
         strcat(cmd,argv[0]);
         strcat(cmd,".jar");
         for(int arg=1;arg<argc;arg++)
              strcat(cmd," ");
              strcat(cmd,argv[arg]);
         system(cmd);
    }Simply compile this to an exe, rename the exe to the name of your jar file and put it in the same directory. Then just type 'MyJarFile' (no jar extension) and it should run. It passes all command live args as well. Comments ?

    Here's a better version. The JAR and the EXE can be anywhere in the PATH:
    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>
    #include <process.h>
    void main(int argc,char *argv[])
         char jar[1024];
         char cmd[1024];
         strcpy(cmd,argv[0]);
         strcat(cmd,".jar");
         _searchenv(cmd,"PATH",jar);
         strcpy(cmd,"java -jar ");
         strcat(cmd,jar);
         for(int arg=1;arg<argc;arg++)
              strcat(cmd," ");
              strcat(cmd,argv[arg]);
         system(cmd);
    }

  • Run a jar on Windows without the command window

    I would like to run a jar and close the command window after starting up. Is this possible please.

    I would like to run a jar and close the command window after starting up. Is this possible please.why do you want to do that? jar files are executable files so when you double click it, it will execute without having to run it from the command prompt. So, you don't have to even open the cmd prompt to run .jar files.

  • Jar file runs from the command line, but not when I double click it

    Hello, I'm running windows xp. I've created an executable jar file and it runs fine from the command line when I type;
    java -jar wizard.jar
    but, when I double click it . . . nothing.
    Any ideas?

    nothing ? that's weird, windows XP should prompt you to select the program you want to use in order to open Jar files (and give you this silly piece of advice to search the web for the appropriate program)
    you might want to check what program (if any) got associated with .jar extensions :
    in Windows Explorer : Tools => Folder Options => File Types

  • Distrubuting jar (the command)

    I am currently developing an installer for my team and it would be really useful to jar various things together at install time. (Dynamically provide a .jar with the functionality users want.)
    Is it ok to have the jar program in my installer? WIll that violate Sun's licensing? The installer will not leave the jar executable on the customer's system.
    Thank you
    (Sorry if there is a better forum for this question.)

    Your best bet would be to get a lawyer, and give him/her the EULA for the JDK.
    .jars are just zip files, so you could either just use any zip tool, or if the installer is in Java, then the java.util.zip and java.util.jar packages.
    Or distribute as multiply zip files, then have the installer build the -classpath argument to the javaw link/bat/sh/�?

  • Can't run JavaFX app as a jar file from command line

    I'm trying to build a JavaFX app from scratch (that is, by including the jar file from the JavaFX SDK rather than by using the special JavaFX project type from NetBeans). It runs fine in NetBeans. However, when I try to launch it as a jar file from the command line (using "java -jar dist\TestApp") I get the following. Has anybody seen this before, and if so how can I fix it?:

    Unsatisfied link means that Java is trying to access a native library, but it cannot be found. As to why this error is being thrown, here is my guess:
    If you open up one of the sample jars with a zip viewer, you will see that the Manifest file has the following entries:
    >
    Manifest-Version: 1.0
    JavaFX-Version: 2.0
    implementation-vendor: Oracle
    implementation-title: BrickBreaker
    implementation-version: 1.0
    JavaFX-Application-Class: brickbreaker.Main
    Created-By: JavaFX Packager
    Main-Class: com/javafx/main/Main
    >
    In other words, a JavaFX project works a bit differently than a normal Java project. com/javafx/main/Main is used as the Main class and your "Main" class is called later.
    If you are trying to build this from a normal Java project, then com/javafx/main/Main will not be created and it will call your Main class right away. Thus, whatever setup is needed to run JavaFX will not occur.
