Running jar files

Hi,
I hv a jar file created by compiling the program in an IDE.Now I want to run the jar file directly from command prompt.i.e I want to run it something like
java -jar myjar.jar <arguments>
Also the program imports another package which is included in the classpath in the IDE.
Now while running the jar file in the command prompt do I hv to set the classpath again to include the imported package.
Can anyone tell me how to do it??

When running a jar, the content of the jar becomes
the classpath. So add any class you need to it and
you should be fine. If your jar depends on classes
outside the jar, it will not run on other systems
without those classes being present.Hi
Thanks a lot.I got the answer I was looking for.
Thanks again!!!!!

Error messege when run jar file

when i run jar file of my project give me that error(Fatel exception occured.program will exist)
what is the reason of that error

"can't get that path". Sounds like requisite classes aren't on the classpath.
Please paste the ENTIRE error message that it's producing into your next reply. You have probably forgotten to include necessary classes - perhaps a JDBC driver - in your JAR file.

Unable to run jar file without lib folder containing swing-layout-1.0.jar

I have done my project through NetBeans 5.0. Eventhough I have copied my lib foloder containing swing-layout-1.0.jar inside my project.jar, I am still unable to run my project.jar in other systems, it is creating an error as Could not find the main class. Program will exit. But if I copy the lib foloder containing swing-layout-1.0.jar in the same path as the project.jar, then my project.jar is running.
But I want to give only the project.jar for other users and not also lib foloder containing swing-layout-1.0.jar each time.
Could someone please help me with this.

When you develop GUI applications using the Netbeans you may endup using netbeans specific jar files in your auto generated code.
And when you build jar files with netbeans it copy the third party jar files used in a application in to a lib folder in the same directory as the jar file of your project. And then set a class path entry to those jar files in your project jar file's manifest file.
So if you want to redistribute the package you have to redistribute your jar file and every thing in the lib folder in with the same directory structure.
If you want to change the structure you will have to change the class path to suit the new structure.

Getting error while running jar file

Hi,
I am getting below error while running the jar file

Running Jar Files created in Sun Java Studio

Hi everyone,
I am still trying to explore the functionalities (especially as regards deployment issues) of this robust IDE. However I do have a problem. I have developed a very basic program that connects to a database (MSSQL) using Java Studio 8. However after building the jar file, if I try to execute the jar file it gives me this message
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver.....
But all goes well within the IDE and it runs well if I use my notepad or vi editor,compile it from the command line and execute the generated class file. The classpath have been set for all the necessary jdbc jar files.
Any Help Will Be Appreciated

1. Sun Java Studio Enterprise 8 is based on NetBeans 4.1 which does not provide direct support for packing an application. One alternative you may want to consider is to use NetBeans 5.0 (http://www.netbeans.info/downloads/download.php?type=5.0) or JSE 8.1 which is based on NB5.0 and which is now in beta (http://developers.sun.com/prodtech/javatools/jsenterprise/downloads/index.jsp).
You may want to refer to http://www.netbeans.org/kb/articles/javase-deploy.html for packing and deploying a standalone application is NB5.0 or JSE8.1.
2. Using JSE8, you may want to try copying all the library jars (including database drivers) used by your application to your projects dist directory manually and then package them all into one jar.
3. You should not have to know the exact location of the jdbc jar on the client machine. How are you instantiating the driver in your code? Are you using 'Class.forName()'? If so, java should be able to pick up the driver from the classpath. (Pl. ref to http://forum.sun.com/jive/thread.jspa?forumID=122&threadID=62696, which may be of help).

Error with running JAR files created with NetBeans

I have been having difficulty running the JAR files that NetBeans compiles. When I run my code from NetBeans, it always works just fine, but when I try to run the compiled JAR I get the following errors:

This is happening for multiple projects now, though I don't remember it happening before. What am I doing wrong? Why is this happening? How can I fix it? Thank you for any insights...

Oh, I forgot to mention, all the NetBeans samples work, just not apps that I create. This is very frustrating!

How to create a running jar-file

I created a "Java Class Library" project including 20 class files in several packages and some libraries.
Because I would like to start the project from the console, I added the main-class property (right-click project, Properties, Run). Then I cleaned and built the project and tried to start it with the following command:
java -jar PROJECTNAME.jarBut it won't work, because the archive is not complete: MANIFEST.MF lacks the main-class and all involved libraries.
I managed to add the main-class attribute manually, but adding all library references seems to be very error-prone.
So does anyone know if I did something wrong or if this is a bug of Creator?
Regards,
Felix

The main intent of this project type is to provide a libraray which normally wouldn't run with a "main". I suggest you use NetBeans to create a "Java Application" project. Here's what is in the README.txt file produced with the jar. This looks like what you're looking to do. So you can create the Jar in NetBeans then if you want to use it in Java Studio Creator, you can add it to the Creator project. Also, if you caught the news at JavaOne, we are providing Creator features for a pack that will run in NetBeans so you won't have to switch back and forth between the tools. Keep an eye on the NetBeans and Creator web sites for more info.
Thanks!

README.txt
========================
BUILD OUTPUT DESCRIPTION
========================
When you build an Java application project that has a main class, the IDE
automatically copies all of the JAR
files on the projects classpath to your projects dist/lib folder. The IDE
also adds each of the JAR files to the Class-Path element in the application
JAR files manifest file (MANIFEST.MF).
To run the project from the command line, go to the dist folder and
type the following:
java -jar "JavaApplication3.jar"
To distribute this project, zip up the dist folder (including the lib folder)
and distribute the ZIP file.
Notes:
* If two JAR files on the project classpath have the same name, only the first
JAR file is copied to the lib folder.
* If the classpath contains a folder of classes or resources, none of the
classpath elements are copied to the dist folder.
* If a library on the projects classpath also has a Class-Path element
specified in the manifest,the content of the Class-Path element has to be on
the projects runtime path.
* To set a main class in a standard Java project, right-click the project node
in the Projects window and choose Properties. Then click Run and enter the
class name in the Main Class field. Alternatively, you can manually type the
class name in the manifest Main-Class element.

Hey I solved the problem in following order
JLabel jbl = new JLabel(new ImageIcon(getClass().getResource("image/theme.GIF")));I have a tips to all who are absorving in this problem
that you should check that whether the extension is in capitalletter or small letter in the jar. Follow the format in your coding
thnx

Could not read Log4j configuration file when I run jar file

Hi,
I'm using Log4J in my application..
I configure the log4j, as follows;
PropertyConfigurator.configure("properties/logging.properties");and then go on to use it.
The .properties is in the root when I jar my source. I use Ant to Jar the file. It all works good when I run the jar file from ant.
The problem is when I run the jar file by double clicking on it, I get an error
" Could not read configuration file [properties/logging.properties]."
I tried the following options;
PropertyConfigurator.configure("/logging.properties");
PropertyConfigurator.configure("./logging.properties");
PropertyConfigurator.configure("../logging.properties");But in all cases, I get corresponding errors on running the jar file through Ant:
log4j:ERROR Could not read configuration file [logging.properties].
log4j:ERROR Could not read configuration file [./logging.properties].
log4j:ERROR Could not read configuration file [../logging.properties].
I want to be able to run the Jar by double clicking on it or through Ant.. Would any one know how to fix this issue so that I can use both methods..

Keep your properties file inside the root folder of your application.It is working fine

Running .jar files in linux on double click

Hi,
i needed a solution to run the jar files on double click in linux system.Necessity is mainly because when i run the jar file by java -jar myapp.jar in terminal it works fine .Iam running my app continuosly in system tray(a server kind).But if i close the terminal my app exits.
How to resolve this ?

I am taking a SWAG.....it sounds like your problem is how to run a java app without a terminal window. So as I recall, there is some way in Linux to enter a command and have it execute in a new process. I don't recall the syntax but maybe putting a '&' character in the command line? Anyway, you should be able to use the method and use "javaw" instead of "java" to launch your app. You should be able to do this in a batch file too. Something like, javaw -jar yourjar.jar &

Running .jar files from Java code

Hi.
I am designing a sort of platform to run some games which are saved in .jar files. Basically this platform is a menu from which the user can select the game which he/she wants to run. It also has the feature of adding new games.
Is is possible to run the .jar file from within java code?
Thanks for any help!

Just list the jar in the classpath list and call the class in the jar.

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);
}
