    Default Re: can some one make me a runable jar file?

    I use the jar command to make my jar files. Here is a batch file I use for one program:
    @Rem create the IRAComps.jar file:
    set JarName=IRAComps.jar
    %DEV_DRIVE%
    cd %DEV_HOME%\JavaDevelopment\Misc_Projects\IRAComps
    jar -cmf IRAComps.mnf %JarName% *.class *.ini 
    cd %DEV_HOME%\JavaDevelopment
    jar -uf %DEV_HOME%\JavaDevelopment\Misc_Projects\IRAComps\IRAComps.jar NormsTools\IntInputField*.class NormsTools\DoubleInputField*.class NormsTools\ErrDialog*.class NormsTools\MakeEnterDoAction*.class NormsTools\MessageArea*.class NormsTools\MyLabel*.class NormsTools\AppletWrapper*.class NormsTools\AppletHelper*.class
    Echo -------------- Created %JarName% ---------------------

    Have you read the following tutorial?
    Lesson: Packaging Programs in JAR Files (The Java™ Tutorials > Deployment)
    What about the process is the problem? Can you package into a jar? Did you include a manifest file defining the main class? When you run the jar, are there exceptions (hence it may look like it is not running)?

    To get any hidden error messages: Open a command prompt window, change to the folder with the jar file and enter:
    java -jar test.jar

    Copy the whole contents of the command prompt window and paste it here.

    Unpackage the jar you created using the jar command to see if all the appropriate .class files exist within the jar, especially Main.class which the class loader cannot find based upon post #6

    1: Is there not an option in Eclipse to export jars by right-clicking your project, and selecting export, and using the export wizard?

    2. The error you got was a little odd, are you sure you exported the WHOLE project?

    Is the Main class in a package? If so, the file's location in the jar file must have the package path.
    See the jar command in post#2. Many classes were in the NormsTools package.

    Default Re: can some one make me a runable jar file?

    What is the name of the package?
    Is the class file in the jar file saved with the package path folder?

    Here is a tool I wrote years ago for checking the contents of jar files:
    http://normsstuff.zxq.net/NormsJavaT...kClassRefs.jar

    For jar files, select the From jar radio button and then click on the Choose button after the filename field and select the jar file to examine.

    For the Help to work you need this jar file:
    http://normsstuff.zxq.net/NormsJavaT...werWParser.jar

    META-INF/MANIFEST.MF
    That's the manifest file. Open it to see. It's needed for the java command to find the starting class.

    # Found 1 classes. 1 NOT found.

    its a image and it say no found is that ok? bc its a image and not a class.


    also i enter in cmd:
    start META-INF/MANIFEST.MF
    and it say:
    windows cantnot find 'META-INF/MANIFEST.MF'. make sure you typed the name correctly

    If the program needs images, you should add the image files to the jar file being sure to put them in the correct folder as used in the get resource method.


    My program only knows about class files. I'm not sure what it does when asked to look for other types of files.

    What is in the manifest file?

    Does the last line in the manifest file have an end of line character? Press Enter at the end of line.

    Where did you see an example using lowercase letters?
    My manifest:
    Main-Class: CheckClassRefs

    Have you read: http://docs.oracle.com/javase/tutori...jar/index.html
